Description

Technical Field

[0001] This disclosure generally relates to earthmoving machinery with grounding devices, and more specifically to tooth tip assemblies with replaceable tooth tips and adapter systems attached to the leading edge or base edge of such grounding devices. Background Technology

[0002] Earthmoving machinery (such as excavators, wheel loaders, hydraulic mining shovels, cable shovels, bucket wheels, bulldozers, and dragline excavators) is typically used to excavate or tunnel through soil or rock, and / or move loose work materials from one location on a work site to another. This earthmoving machinery includes a variety of earthmoving implements, such as buckets or blades, used for excavating or moving work materials. These implements can suffer significant wear and tear due to the abrasion and impacts experienced during earthmoving operations.

[0003] To facilitate earthmoving processes and extend implement life, multiple toothed assemblies can be placed and attached to the implement's surface along the base edge. The toothed assemblies protrude forward from the base edge, serving as the first point of contact and penetration with the work material and reducing wear on the base edge. With this arrangement, the toothed assemblies may wear and break due to repeated engagement with the work material. Ultimately, while the toothed assemblies must be replaced, the implement can remain usable after multiple toothed assembly replacements. Depending on the equipment's purpose and the diversity of work materials, it may also be necessary to modify the type or shape of the toothed assemblies to utilize the implement most effectively.

[0004] By providing the tooth tip assembly as a two-part system, installation and replacement of the tooth tip assembly can be facilitated. The system may include an adapter attached to the base edge of the implement and a grounded tooth tip configured to attach to the adapter. The adapter and the grounded tooth tip can be connected via a retaining mechanism. The adapter may be welded, bolted, or otherwise secured to the base edge and the tooth tip.

[0005] U.S. Patent Publication No. 2022 / 0290413A1 (“'413 application”), published September 15, 2022 by Michael B. Roska et al., discloses a wear-resistant assembly comprising a base having a nose and a wear-resistant element having a slot. The nose and slot in the '413 application include complementary stabilizing surfaces in a front and a rear portion. Both the front and rear portions include bearing surfaces. For example, the front portion includes a first front bearing surface on the top or bottom of a mounting cavity, two second front bearing surfaces on the top or bottom of the mounting cavity opposite to the first front bearing surface, and a front bearing wall perpendicular to the front bearing surface at the front end of the mounting cavity. Simultaneously, the rear portion includes a first rear bearing surface on the top or bottom of the mounting cavity opposite to the first front bearing surface, and two second rear bearing surfaces on the top or bottom of the mounting cavity opposite to the first rear bearing surface.

[0006] The '413 application provides a base nose and slot with complementary bearing surfaces. However, the '413 application may not maximize the contact area of ​​the bearing surfaces and the friction under load, or may not properly support the load conditions from every direction, resulting in increased stress on the nose and wear parts, increased relative movement between the nose and wear parts, increased wear concentration leading to premature failure, and increased load on the holding mechanism.

[0007] This disclosure aims to overcome one or more of the disadvantages described above and / or other problems of the prior art. Summary of the Invention

[0072] Asymmetric adapter ( FIG. 4 to FIG. 11 and FIG. 33 to FIG. 39 )

[0073] FIG. 4 to FIG. 11 and FIG. 33 to FIG. 39 An exemplary embodiment of adapter 12 is shown in more detail below. FIG. 4 This is an isometric view of the exemplary adapter 12. (Reference) FIG. 4 The adapter 12 may include a rear portion 19 having a top strap 20 and a bottom strap 22, a middle portion 24, and a nose 26 disposed at the front or forward position (e.g., facing direction F) of the adapter 12. A gap 21 may be defined between the top strap 20 and the bottom strap 22 for receiving the base edge 18 of the loader bucket assembly 1 and / or the excavator bucket assembly 6. FIG. 1 , FIG. 2 The nose portion 26 may include one or more retaining holes 16, which are configured to engage with the retaining mechanism 13. FIG. 3The adapter 12 is mated to secure the tooth tip 14. The retaining hole 16 may include, for example, a through hole or recess configured to receive the retaining mechanism 13. The retaining hole 16 may also include threads and / or internal grooves. Similarly, in some exemplary embodiments, the retaining hole in the nose 26 (corresponding to the retaining hole 16) may also include threads and / or internal grooves.

[0074] FIG. 5 Examples FIG. 4 Side view of adapter 12. (See attached image.) FIG. 5 As shown, the top band 20 may have a bottom surface 30 and a top surface 31 facing the gap 21. The bottom band 22 may have a top surface 34 and a bottom surface 35 facing the gap 21. The adapter 12 can be secured to the base edge 18 of the loader bucket assembly 1 or the excavator bucket assembly 6 by attaching the top band 20 and the bottom band 22 to the base edge 18 using any connection method or mechanism known to those skilled in the art. FIG. 1 , FIG. 2 The adapter 12 is positioned appropriately on the substrate. In one exemplary embodiment, the top band 20, bottom band 22, and base edge 18 may have corresponding holes (not shown) through which fasteners (not shown), such as bolts or rivets, can be inserted to secure the adapter 12 in place. Alternatively, the top band 20 and bottom band 22 may be welded to the base edge 18 such that the adapter 12 and the base edge 18 do not move relative to each other during use. To reduce the impact of the top surface weld and the bottom surface weld on the metal strength of the base edge 18, the top band 20 and bottom band 22 may be configured with different shapes to minimize the overlap of welds formed on the top and bottom surfaces of the base edge 18.

[0075] It is conceivable that other connection configurations of adapter 12 could be provided as alternatives to the top band 20 and bottom band 22 illustrated and described above. For example, the rear portion 19 of adapter 12 could be provided with a single top band 20 without a bottom band 22, wherein the top band 20 is attached to the base edge 18 ( FIG. 1 , FIG. 2 The top surface of the adapter 12. Alternatively, a single bottom band 22 may be provided instead of a top band 20, wherein the bottom band 22 is attached to the bottom surface of the base edge 18. As another alternative, a single center band may be provided on the rear portion of the adapter 12, wherein the center band is inserted into a gap in the base edge 18 of the loader bucket assembly 1 or the excavator bucket assembly 6.

[0076] The intermediate portion 24 of the adapter 12 provides a transition between the rear portion 19 and the nose 26. The intermediate portion 24 may extend between the rear portion 19 and the rear end of the nose 26 (as defined by a vertical plane “P”), which may generally be arranged perpendicular to a longitudinal axis “A” passing through the nose 26. The longitudinal axis “A” may be positioned midway between the two sides of the nose 26, as will be explained below. The nose 26 may be configured to be centered on the corresponding nasal cavity 126 of the tooth tip 14. FIG. 19 The receiving plane “P” can be positioned along the longitudinal axis “A” at the location where the nose 26 of the adapter 12 may have its maximum cross-sectional area before transitioning to the intermediate portion 24. The plane P can also generally be perpendicular to the longitudinal axis A.

[0077] FIG. 6 and FIG. 7 Examples FIG. 4 Isometric view of the nose 26 of adapter 12. (e.g.) FIG. 6 and FIG. 7 As shown, the nose portion 26 may have a front surface 36, a top surface 46, opposing side surfaces 60, and a bottom surface 66. In one embodiment, the side surface 60 may have a corresponding retaining hole 16 (e.g., similar to...). FIG. 3 ), maintain mechanism 13 (e.g., similar to FIG. 3 The tooth tip 14 can be inserted into the retaining hole to secure it in the proper position on the nose 26 of the adapter 12.

[0078] like FIG. 6 As shown, the front surface 36 of the nose 26 may include a generally planar portion surrounded by curved edge portions. The planar portion of the front surface 36 may be substantially perpendicular to the substantially longitudinal axis "A" ( FIG. 5 Orientation, the longitudinal axis "A" can be located on the opposite side surface 60 of the nose 26. FIG. 6 Centered between and perpendicular to the vertical plane "P" of the rear part of the nose 26 of the limiting adapter 12. FIG. 5 Alternatively, the planar portion of the front surface 36 may form an angle of 1° to 5° counterclockwise relative to the plane "P," or an angle of -1° to -15° clockwise relative to the plane P. In some exemplary embodiments, the front surface 36 may include a degree of curvature (e.g., it may have a curved surface surrounded by curved edge portions), such as FIG. 7 exemplified.

[0079] FIG. 8 Examples FIG. 4 A side view of the nose 26 of the adapter 12, and FIG. 9 Examples FIG. 4 Front view of the nose 26 of adapter 12. (See attached image.) FIG. 9As shown, the front surface 36 may be hexagonal, including a bottom edge 37, opposing side edges 38 oriented at approximately 90° relative to the bottom edge 37, a top horizontal edge 39 oriented approximately parallel to the bottom edge 37, and an opposing top inclined edge 40 connecting the top horizontal edge 39 to the side edges 38. The angle q between the top horizontal edge 39 and the top inclined edge 40 may be between approximately 18.5° and 30°, and may preferably be approximately 24.5°. FIG. 6 As shown, the front edges 37 to 40 can be curved.

[0080] The top surface 46 of the nose 26 FIG. 6 It can be configured to support the tooth tip 14 during use of the loader bucket assembly 1 or the excavator bucket assembly 6, and to facilitate holding the tooth tip 14 on the nose 26 when bearing the load of the work material. FIG. 8 and FIG. 10 As shown, the top surface 46 may include a front portion 48 disposed near the front surface 36, a transition portion 51 extending rearward from the front portion 48 toward the plane P, and a rear portion 52 extending rearward from the transition portion 51 toward the plane P. The front portion 48 may include a generally planar front center surface 49 extending rearward from the top horizontal edge 39 of the front surface 36. The front center surface 49 may be disposed between two generally planar, opposing front inclined surfaces 50 that extend rearward from the top inclined edge 40 of the front surface 36 and slope downward away from the front center surface 49 in a lateral direction (e.g., along the +B and -B directions, perpendicular to the longitudinal axis A). FIG. 10 Examples FIG. 4 A top view of the nose 26 of adapter 12. (See attached image.) FIG. 10 As illustrated, as the front center surface 49 extends rearward from the top horizontal edge 39, the lateral width of the front center surface 49 may decrease symmetrically, resulting in the front center surface 49 having a generally trapezoidal shape. Alternatively, the lateral width of the front center surface 49 may be constant, or it may increase as the front center surface 49 extends rearward from the top horizontal edge 39.

[0081] like FIG. 8As shown, the front center surface 49 may extend upward away from the top horizontal edge 39, such that the front center surface 49 and the front surface 36 may be arranged at an angle f of 85° to 105°, preferably about 95°. Alternatively, the front center surface 49 may extend substantially perpendicular to the front surface 36, for example, at an angle of 88° to 92°, preferably 90°. Alternatively, the front center surface 49 may extend at an acute angle relative to the front surface 36, for example, at an angle of 85° to 87°. The front side inclined surface 50 may be oriented relative to the front center surface 49, such that the two surfaces may be arranged at an angle θ of 18.5° to 30°, preferably about 24.5°. The front side inclined surface 50 may help provide stability to the tooth tip assembly 10 during downward and lateral loading modes, for example, by acting as a wedge-shaped surface to reduce the distance between the nose 26 of the adapter 12 and the nasal cavity 126 of the tooth tip 14. FIG. 19 The relative movement between the nose 26 of the adapter 12 and the nasal cavity 126 of the tooth tip 14 is further increased by the front inclined surface 50, thereby reducing stress throughout the nose 26. Furthermore, when a load is applied to the tooth tip assembly 10, the front inclined surface 50 additionally increases friction, thereby reducing the load on the tooth tip 14 and the retaining mechanism 13, especially when combined with other lateral inclined surfaces (e.g., the rib-side surface 80 described below).

[0082] Back FIG. 10 The rear portion 52 of the top surface 46 may include a generally planar rear center surface 53 extending rearward from the transition portion 51 toward the middle portion 24 of the adapter 12. The planar rear center surface 53 may be arranged between two opposing rearward inclined surfaces 54 extending rearward from the transition portion 51 and sloping downward away from the rear center surface 53 in the lateral directions +B and -B. The rearward inclined surfaces 54 serve to provide increased stability; for example, during downward and lateral loading of the tooth tip assembly 10, the rearward inclined surfaces reduce relative movement between the nose 26 and the tooth tip 14 and increase the contact area by acting as wedge-shaped surfaces. Furthermore, the increased contact area provided by the rearward inclined surfaces 54 reduces stress on the nose 26.

[0083] As the rear center surface 53 extends rearward, its lateral width may initially increase and then decrease. In some embodiments, the width of the rear center surface 53 near the front center surface 49 is 0.1 to 0.4 times, preferably about 0.23 times, the lateral width ("RTW") at the rear of the nose 26 (at vertical plane "P"). In some embodiments, the width of the rear center surface 53 at its widest point as it extends rearward is 0.6 to 0.9 times, preferably about 0.73 times, the lateral width ("RTW") at the rear of the nose 26. In some embodiments, the width of the rear center surface 53 near the middle portion 24 of the adapter 12 is 0.3 to 0.6 times, preferably about 0.46 times, the lateral width ("RTW") at the rear of the nose 26. The rear center surface 53 may be inclined upward relative to the front center surface 49. The different angles of the front center surface 49 and the rear center surface 53 relative to the approximate longitudinal axis "A" provide the advantage of generating friction on the front center surface 49, thereby transferring the load from the retaining mechanism 13 to the nose 26 of the adapter 12. For example, as FIG. 8 As shown, the rear central surface 53 can be oriented relative to the front central surface 49 such that the angle between the two surfaces is 0° to 15°, preferably about 9°. Furthermore, the tilt angle of the rear central surface 53 relative to the generally longitudinal axis "A" can be about 5° to 25°, preferably 14°. The tilt of the rear central surface 53 facilitates the insertion of the nose 26 into the nasal cavity 126 of the tooth tip 14. FIG. 19 In the middle, the width of the central surface 53 then restricts the twisting of the tooth tip 14 after it is mounted on the nose 26.

[0084] like FIG. 10 As further illustrated, the rear inclined surface 54 may include a generally planar triangular front bowtie surface 55 and a generally planar triangular rear bowtie surface 56, the two surfaces oriented with their vertices pointing towards each other. The front bowtie surface 55 provides the advantage of acting as a primary wedge surface during push-in loading. For example, as FIG. 8 As shown, the front bowtie-shaped surface 55, extending in the rearward direction R, can be inclined upward relative to the front inclined surface 50 (e.g., in the U direction). For example, the front bowtie-shaped surface 55 can be oriented relative to the front inclined surface 50 such that the angle between the two surfaces is 15° to 27.5°, preferably about 21.5°. Furthermore, for example, as... FIG. 9 As shown, the front bowtie-shaped surface 55 may be tilted downwards (e.g., in the D direction) as it extends from the rear center surface 53 in the lateral directions +B and -B. For example, the front bowtie-shaped surface 55 may be oriented relative to the rear center surface 53 such that the angle between the two surfaces is 17.5° to 32.5°, preferably about 25°.

[0085] For example, such as FIG. 8 andFIG. 10 As shown, the rear bowtie surface 56 may be inclined downwards (e.g., in the D direction) as it extends from the rear center surface 53 in the lateral directions +B and -B. The inclination angle between the rear bowtie surface 56 and the rear center surface 53 may differ from the inclination angle between the front bowtie surface 55 and the rear center surface 53. More specifically, the inclination angle between the rear bowtie surface 56 and the rear center surface 53 may be greater than the inclination angle between the front bowtie surface 55 and the rear center surface 53. For example, the rear bowtie surface 56 may be oriented relative to the rear center surface 53 such that the angle between the two surfaces is 30° to 45°, preferably about 37.5°. Furthermore, when the rear bowtie surface 56 extends rearward from the front bowtie surface 55, the rear bowtie surface 56 may be oriented approximately parallel to the generally longitudinal axis "A". Alternatively, when the back necktie surface 56 extends rearward from the front necktie surface 55, the back necktie surface 56 may be tilted upward, but at a shallower angle relative to the generally longitudinal axis "A" than the angle of the front necktie surface 55. For example, the back necktie surface 56 may be oriented relative to the front necktie surface 55 such that the angle between the two surfaces is 18.5° to 30°, preferably about 24.5°. Reference FIG. 8 The relative surface angles of the front inclined surface 50, the front collarbone-shaped surface 55, and the rear collarbone-shaped surface 56 provide the advantage of wedging the tooth tip 14 into the nose 26, especially during front loading, reducing the overall movement of the tooth tip 14 and dispersing stress and wear through the nose 26.

[0086] refer to FIG. 10 The front portion 48 of the top surface 46 of the nose 26, the rear portion 52 of the top surface 46 of the nose 26, and the middle portion 24 of the adapter 12 may each be separated by a transition portion 51, which may include one or more curved surfaces that transition between relative angles of otherwise adjacent, normally planar surfaces. Individually defined surfaces within the front portion 48 and the rear portion 52 of the top surface 46 (e.g., front center surface 49 and rear center surface 53, front lateral inclined surface 50, and front bowtie surface 55 and rear bowtie surface 56) may also be separated by the transition portion 51. FIG. 33 Examples are shown along such FIG. 5 The illustrated horizontal cross-sectional view taken by the CC line. FIG. 33 Examples of surfaces associated with the nose 26 of adapter 12 and discussed above are also shown. For example... FIG. 33 As illustrated, in some exemplary embodiments, the top band 20 of the adapter 12 may include an opening or a recess 23.

[0087] FIG. 11 yes FIG. 4 A bottom view of the nasal cavity of the adapter. (As shown in...) FIG. 11As can be seen, the bottom surface 66 may include a generally planar front portion 68 disposed near and extending rearward from the front surface 36, and a rear portion 70 extending rearward toward the middle portion 24 of the adapter 12. A transition portion 51 may be disposed between the front portion 68 and the rear portion 70. The front portion 68 provides a flat and stable surface as the primary contact area during loading, which has the advantage of reducing wear on the tooth tip assembly 10. FIG. 8 As shown, the front portion 68 can be oriented at an angle of 85° to 105° relative to the front surface 36, preferably at an angle of about 90°. Furthermore, the front portion 68 can be oriented at an angle of 0° to 15° relative to the front center surface 49, preferably at an angle of about 5°. This orientation of the front portion 68 provides the advantage of increased friction between the tooth tip 14 and the adapter 12, thereby reducing slippage, for example, when the tooth tip 14 is loaded in the upward direction, resulting in a reduction in load on the retaining mechanism 13.

[0088] As in FIG. 11 As can be seen, the rear portion 70 of the bottom surface 66 may include: an opposing, generally planar shoulder surface 72 that slopes downward (e.g., in the D direction, see...). FIG. 8 Alternatively, it may be parallel to the front portion 68; and a bottom rib 74, which slopes downward relative to both the front portion 68 and the shoulder surface 72 (e.g., in the D direction). FIG. 8 As shown, the shoulder surface 72 can be oriented at an angle of 0° to 10° relative to the front portion 68, preferably at an angle of about 4°.

[0089] As in FIG. 11 As can be seen, the bottom rib 74 of the bottom surface 66 may include a downward slope relative to the front portion 68 (e.g., in the D direction, see...). FIG. 8 The front rib portion 76 is typically planar, and the portion slopes downward relative to the front rib portion 76 (e.g., in the D direction, see...). FIG. 8 The rear rib portion 78, which is typically planar, is located between opposing rib side surfaces 80 of the front rib portion. The bottom rib 74 provides advantages such as increased stability during side loading and increased wedging during push-in loading. FIG. 8 As shown, the front rib portion 76 may be oriented relative to the front portion 68 such that the angle between the two surfaces is 6° to 18°, preferably about 12.5°. The rear rib portion 78 may be oriented relative to the front rib portion 76 such that the angle between the two surfaces is 0° to 15°, preferably 6°. For example, the different angles of the front rib portion 76 and the rear rib portion 78 provide the benefits of reducing relative movement between the adapter 12 and the tooth tip 14, reducing wear, and distributing stress more evenly.

[0090] As in FIG. 11As can be seen, the rib-side surfaces 80 of the bottom rib 74 may include a front rib-side surface 81 and a rear rib-side surface 82. The front rib-side surface 81 connects the front rib portion 76 to the shoulder surface 72. The rear rib-side surface 82 connects the rear rib portion 78 to the shoulder surface 72. The front rib-side surfaces 81 of the bottom rib 74 may be generally parallel to each other, such that the lateral width of the front rib portion 76 (along the +B and -B directions) is generally constant as the front rib portion 76 extends rearward. Alternatively, the front rib-side surfaces 81 of the bottom rib 74 may be oriented relative to each other, such that the distance between the front rib-side surfaces 81 decreases approximately symmetrically with a longitudinal taper angle "LTA" of 0° to 20° relative to a longitudinal line oriented parallel to the generally longitudinal axis "A". Furthermore, in some exemplary embodiments (not shown), the rear rib-side surfaces 82 of the bottom rib 74 may be generally parallel to each other, such that the lateral width of the rear rib portion 78 (e.g., along the +B and -B directions) is approximately constant as the rear rib portion 78 extends rearward. Alternatively, as FIG. 11 As shown, the rear rib side surfaces 82 of the bottom rib 74 can be oriented relative to each other such that the distance between the rear rib side surfaces 82 decreases approximately symmetrically at a longitudinal taper angle "LTA" of 0° to 20°, preferably about 5°, relative to a longitudinal line oriented parallel to the generally longitudinal axis "A". The orientation of the rib side surfaces 80 relative to the generally longitudinal axis "A" provides the advantage of increased wedging, thereby reducing relative movement, including reduced lateral pivoting, and reduced wear during push-in loading and downward loading. FIG. 9 As shown, the rib side surfaces 80 of the bottom rib 74 can be oriented relative to each other such that the distance between the rib side surfaces 80 decreases approximately symmetrically with a vertical taper angle “VTA” of 30° to 50°, preferably about 39.5°, relative to the parallel vertical line. Furthermore, the rib side surfaces 80 can be oriented relative to the shoulder surface 72 such that the angle between the two surfaces is 40° to 60°, preferably about 50.5°. This orientation of the rib side surfaces 80 provides the following advantages: increased stability during side loading; reduced nose volume; enhanced strength; and an additional wedging effect that increases the contact area and reduces sliding motion and associated wear.

[0091] refer to FIG. 11 The front portion 68 of the bottom surface 66 of the nose 26, the rear portion 70 of the bottom surface 66 of the nose 26, and the middle portion 24 of the adapter 12 may each be separated by a transition portion 51, which may include one or more curved surfaces that transition between relative angles of otherwise adjacent, normally planar surfaces. Individually defined surfaces within the front portion 68 and the rear portion 70 of the bottom surface 66 (e.g., shoulder surface 72, front rib portion 76, rear rib portion 78, and rib side surface 80) may also be separated by the transition portion 51.

[0092] like FIG. 7As shown, the side surface 60 of the nose 26 may generally be planar and extends upward between the bottom surface 66 and the top surface 46. FIG. 8 As illustrated, the side surface 60 may include: a generally planar front side surface 61 disposed adjacent to the front surface 36; a generally planar middle side surface 62 extending rearward from the front side surface 61; and a rear side surface 63 extending rearward from the middle side surface 62 to the middle portion 24 of the adapter 12. The front side surfaces 61 may be longitudinally aligned such that they separate the front inclined surface 50 of the top surface 46 from the front portion 68 of the bottom surface 66. The middle side surfaces 62 may be longitudinally aligned such that they separate the front bowtie-shaped surface 55 of the top surface 46 from the shoulder surface 72 of the bottom surface 66. The rear side surfaces 63 may be longitudinally aligned such that they separate the rear bowtie-shaped surface 56 of the top surface 46 from the shoulder surface 72 of the bottom surface 66.

[0093] like FIG. 10 As shown, the front side surface 61 and the middle side surface 62 can be parallel and continuous as they extend rearward from the side edge 38 of the front surface 36. The front side surface 61 and the middle side surface 62 can be oriented relative to the front surface 36 such that the angle between these surfaces is 90° to 105°, preferably about 93°. Furthermore, as... FIG. 8 As shown, the front surface 61 can be configured such that the distance between the top surface 46 and the bottom surface 66 is approximately constant as the front surface 61 extends rearward from the side edge 38. Alternatively, the front surface 61 can be configured such that the distance between the top surface 46 and the bottom surface 66 increases slightly as the front surface 61 extends rearward from the side edge 38. The intermediate side surface 62 can be configured such that the distance between the top surface 46 and the bottom surface 66 increases significantly as the intermediate side surface 62 extends rearward.

[0094] like FIG. 10As shown, as the rear side surfaces 63 extend rearward from the intermediate side surface 62, they may be inclined outward relative to the front side surface 61 and the intermediate side surface 62 (e.g., along the +B and -B directions), such that the lateral distance between the rear side surfaces 63 (e.g., along the +B and -B directions) increases symmetrically as the rear side surfaces 63 extend rearward. For example, the rear side surfaces 63 may be inclined outward relative to the intermediate side surface 62 at an angle greater than 0° to 15°, preferably at an angle of about 7°. An angle greater than 0° provides the following advantages: allowing the rear side surfaces 63 to act as wedge surfaces during push-in loading; increasing the contact surface between the adapter 12 and the tooth tip 14 during operation, and thus reducing slippage and wear; and improving removability during removal by reducing friction between the adapter 12 and the tooth tip 14. Alternatively, in some exemplary embodiments, the rear side surfaces 63 may be oriented generally parallel to the intermediate side surface 62. In some exemplary embodiments, the rear surface 63 may be configured such that the distance between the top surface 46 and the bottom surface 66 decreases slightly as the rear surface 63 extends rearward.

[0095] The front side surface 61, middle side surface 62, rear side surface 63, top surface 46, bottom surface 66 of the side surface 60 of the nose 26 and the middle portion 24 of the adapter 12 may be separated by a transition portion 51, which may include one or more curved surfaces that transition between relative angles of originally adjacent, normally planar surfaces.

[0096] like FIG. 8 As shown, the vertical height (“RVH”) at the rear of the nose portion 26 (at the vertical plane “P”) can be 0.5 to 1.0 times the longitudinal length (“LL”) of the nose portion 26, where the longitudinal length (“LL”) is defined as the distance from the vertical plane “P” to the anterior surface 36 along the approximately longitudinal axis “A”. The vertical height (“FVH”) at the front of the nose portion 26 (at the anterior surface 36) can be 0.2 to 0.5 times the longitudinal length (“LL”) of the nose portion 26. FIG. 10 As shown, the lateral width (“RTW”) at the rear of the nose portion 26 (at vertical plane “P”) can be 0.8 to 2.0 times the lateral width (“FTW”) at the front of the nose portion 26 (at front surface 36). The lateral width (“FTW”) at the front of the nose portion 26 (at front surface 36) can be 0.4 to 1.5 times the longitudinal length (“LL”) of the nose portion 26. The longitudinal length (“LL”) of the nose portion 26 can be 0.7 to 2.0 times the lateral width (“RTW”) at the rear of the nose portion 26 (at vertical plane “P”). FIG. 34 A top view of adapter 12 is shown, and FIG. 35 Examples are shown along FIG. 34 The image shows a vertical cross-sectional view of the adapter taken by the EE line.FIG. 35 Some of the surfaces associated with the nose 26 of the adapter 12 and discussed above are also illustrated.

[0097] FIG. 36 Examples are shown with cross-section lines FF, GG, and HH. FIG. 4 A side view of the adapter. (e.g.) FIG. 36 As illustrated, the cross sections corresponding to the FF line, GG line, and HH line can be located at distances of approximately 0.1X, 0.4X, 0.8X, and 1.0X from the anterior surface 36 of the nose 26. FIG. 37 Examples are shown along such FIG. 36 A cross-sectional view of the nose 26 of the FF line shown. (See attached image.) FIG. 37 As illustrated, the front center surface 49 may be arranged between two generally planar, opposing front inclined surfaces 50. The front inclined surfaces 50 may be oriented relative to the front center surface 49 such that the angle between the two surfaces is 18.5° to 30°, preferably about 24.5°. FIG. 38 Examples are shown along such FIG. 36 A cross-sectional view of the nose 26 of the GG line shown. (See attached image.) FIG. 38 As illustrated, the front bowtie-shaped surface 55 may be tilted downwards (e.g., in the D direction) as it extends from the rear center surface 53 in the lateral directions +B and -B. For example, the front bowtie-shaped surface 55 may be oriented relative to the rear center surface 53 such that the angle between the two surfaces is 17.5° to 32.5°, preferably about 25°.

[0098] FIG. 39 Examples are shown along such FIG. 36 A cross-sectional view of the nose 26 of the GG line shown. (See attached image.) FIG. 39 As illustrated, the back necktie surface 56 may slope downwards (e.g., in the D direction) as it extends from the back center surface 53 in the lateral directions +B and -B. The angle of inclination between the back necktie surface 56 and the back center surface 53 may differ from the angle of inclination between the front necktie surface 55 and the back center surface 53 (see [reference]). FIG. 38 More specifically, the angle of inclination between the back bowtie surface 56 and the back center surface 53 may be greater than the angle of inclination between the front bowtie surface 55 and the back center surface 53. For example, the back bowtie surface 56 may be oriented relative to the back center surface 53 such that the angle between the two surfaces is 30° to 45°, preferably about 37.5°.

[0099] Symmetrical adapter ( FIG. 12 to FIG. 17 and FIG. 40 to FIG. 45 )

[0100] FIG. 12 to FIG. 17 and FIG. 40 to FIG. 45 An alternative embodiment of the adapter 12, including a symmetrical nose 27, is shown.FIG. 12 This is a side view of an alternative embodiment of the exemplary adapter 12. A symmetrical nose 27 is configured to be received by a corresponding alternative embodiment of a tooth tip 14, which includes a symmetrical nose cavity 127. FIG. 27 to FIG. 32 The symmetrical nose 27 and the corresponding symmetrical nose cavity 127 provide the following benefits: allowing the user to reverse the top-bottom orientation of the tooth tip 14 when it is attached to the adapter 12, resulting in more uniform wear on the top and bottom surfaces of the tooth tip. The symmetrical nose 27 also allows for the mounting of a tooth tip that provides an angle of attack in one orientation and a different angle of attack when mounted in another orientation (e.g., rotated 180° from that orientation). The intermediate portion 24 of the adapter 12 provides a transition between the rear portion 19 and the symmetrical nose 27. The intermediate portion 24 may extend between the rear portion 19 and the rear end of the symmetrical nose 27 (as defined by a vertical plane “P”), which may generally be arranged perpendicular to the longitudinal axis “A” passing through the symmetrical nose 27. The longitudinal axis “A” may be located midway between the two sides of the symmetrical nose 27, as explained below. The plane “P” can be positioned along the longitudinal axis “A” at a location where the adapter 12 can have its maximum cross-sectional area before transitioning to the intermediate portion 24. The plane P can also generally be perpendicular to the longitudinal axis A.

[0101] FIG. 13 and FIG. 14 Examples FIG. 12 An isometric view of the nose 27 of adapter 12. (See attached image.) FIG. 13 and FIG. 14 As shown, the symmetrical nose portion 27 may have a front surface 36, opposing top surfaces 46 and bottom surfaces 66, and opposing side surfaces 60. FIG. 5 to FIG. 11 Unlike the asymmetrical nose 26, the top surface 46 and bottom surface 66 may have similar features and may extend rearward at similar angles relative to a longitudinal axis "A," the orientation of which is defined as the center located between opposing side surfaces 60 of the symmetrical nose 27 and between the top surface 46 and the bottom surface 66. In one embodiment, the side surface 60 may have corresponding retaining holes 16 (not shown), into which a retaining mechanism 13 (not shown) may be inserted to secure the tooth tip 14 to the appropriate position on the symmetrical nose 27 of the adapter 12 (e.g., FIG. 3 (As shown). The retaining hole 16 may include, for example, a through hole or recess configured to receive the retaining mechanism 13. The retaining hole 16 may also include threads and / or internal grooves.

[0102] The anterior surface 36 of the symmetrical nose portion 27 may be substantially similar to the anterior surface 36 of the nose portion 26. The anterior surface 36 may include a planar portion (such as... FIG. 13 (as shown) or may include a certain degree of curvature (such as...) FIG. 14 (As shown).FIG. 15 yes FIG. 12 Side view of the nose 27 of adapter 12. (See attached image.) FIG. 15 As shown, the planar portion of the front surface 36 may be approximately perpendicular to the generally longitudinal axis A or may be consistent with the above description. FIG. 5 and FIG. 6 The manner described is similar to that of angular orientation (e.g., see the tilt of the front surface 36 relative to axis Z).

[0103] FIG. 16 yes FIG. 12 Front view of the nose section 27 of the adapter. (See attached image.) FIG. 16 As shown, the front surface 36 may be octagonal, including opposing top and bottom horizontal edges 39, opposing side edges 38 oriented at approximately 90° relative to the top and bottom horizontal edges 39, and opposing top and bottom inclined edges 40 connecting the top and bottom horizontal edges 39 to the side edges 38. The angle between the top and bottom horizontal edges 39 and the top and bottom inclined edges 40 is approximately 18.5° to 30°, preferably approximately 24.5°. FIG. 13 and FIG. 14 As shown, the front edge 38 to 40 can be curved.

[0104] The top surface 46 of the symmetrical nose 27 can be configured to support the tooth tip 14 during use of the loader bucket assembly 1 or the excavator bucket assembly 6, and to facilitate holding the tooth tip 14 on the symmetrical nose 27 when bearing the load of the work material.

[0105] FIG. 17 yes FIG. 12 Bottom view of the nose section 27 of the adapter. (See attached image.) FIG. 17 As shown, the top surface 46 and bottom surface 66 may include a front portion 48 disposed near the front surface 36, a transition portion 51 extending rearward from the front surface 36, and a rear portion 52 extending rearward from the transition portion 51 toward the middle portion 24 of the adapter 12. The front portion 48 may include a generally planar front center surface 49 extending rearward from the top or bottom horizontal edge 39 of the front surface 36 and situated between two generally planar, opposing front inclined surfaces 50 extending rearward from the top or bottom inclined edge 40 of the front surface 36 and inclined laterally (e.g., along the +B and -B directions) away from the front center surface 49 toward the side surface 60. As the front center surface 49 extends rearward from the top or bottom horizontal edge 39, the lateral width of the front center surface 49 (e.g., along the +B and -B directions) may decrease symmetrically, resulting in the front center surface 49 having a shape similar to an isosceles trapezoid, such as... FIG. 17As illustrated in the example embodiment. Alternatively, the lateral width of the front center surface 49 may be constant, or it may increase as the front center surface 49 extends rearward from the top horizontal edge or the bottom horizontal edge 39.

[0106] like FIG. 15 As shown, the front center surface 49 may extend rearward away from the generally longitudinal axis "A" (e.g., in the upward U direction or the downward D direction), such that the front center surface 49 and the front surface 36 can be arranged at an angle of 85° to 105°. The front inclined surface 50 may be oriented relative to the front center surface 49 such that these surfaces form an angle of 18.5° to 30°, preferably about 24.5°. The front inclined surface 50 provides stability to the tooth tip assembly 10 during upward, downward, and lateral loading modes, for example by acting as a wedge-shaped surface to reduce relative movement between the symmetrical nose 27 of the adapter 12 and the symmetrical nose cavity 127 of the tooth tip 14. The front inclined surface 50 additionally increases the contact area between the symmetrical nose 27 of the adapter 12 and the symmetrical nose cavity 127 of the tooth tip 14, thereby reducing stress throughout the symmetrical nose 27. Furthermore, when a load is applied to the tooth tip assembly 10, the front inclined surface 50 additionally increases the frictional force, thereby reducing the load on the tooth tip 14 and the retaining mechanism 13, especially when combined with other lateral inclined surfaces (e.g., the rear bowtie-shaped surface 56 described below).

[0107] Back FIG. 17 The rear portion 52 of the top surface 46 and the bottom surface 66 may include a generally planar rear center surface 53 that extends rearward from the transition portion 51 toward the middle portion 24 of the adapter 12 and is located between two opposing rearward inclined surfaces 54 that extend rearward from the transition portion 51 and slope downward away from the rear center surface 53 in a lateral direction (e.g., along the +B and -B directions) (e.g., in the D direction, see...). FIG. 15 The rearward inclined surface 54 serves to provide increased stability, for example, during upward, downward, and lateral loading of the tooth tip assembly 10. This rearward inclined surface reduces relative movement between the symmetrical nose 27 and the tooth tip 14 and increases the contact area by acting as a wedge-shaped surface. Furthermore, the increased contact area provided by the rearward inclined surface 54 reduces stress on the symmetrical nose 27.

[0108] As the rear center surface 53 extends rearward from the transition portion 51, the lateral width of the rear center surface 53 (e.g., along the +B and -B directions) may initially increase and then decrease. In some embodiments, the width of the rear center surface 53 near the front center surface 49 is 0.1 to 0.4 times, preferably about 0.23 times, the lateral width (“RTW”) at the rear of the nose 26 (at the vertical plane “P”). In some embodiments, the width of the rear center surface 53 at its widest point as it extends rearward from near the front center surface 49 is 0.6 to 0.9 times, preferably about 0.73 times, the lateral width (“RTW”) at the rear of the nose 26. In some embodiments, the width of the rear center surface 53 near the middle portion 24 of the adapter 12 is 0.3 to 0.6 times, preferably about 0.46 times, the lateral width (“RTW”) at the rear of the nose 26. FIG. 15 As illustrated, the rear center surface 53 may extend rearward away from the generally longitudinal axis "A" (e.g., in the U and D directions). The different angles of the front center surface 49 and the rear center surface 53 relative to the generally longitudinal axis "A" provide the advantage of generating friction on the front center surface 49, thereby transferring the load from the retaining mechanism 13 to the symmetrical nose 27 of the adapter 12. For example, as FIG. 15 As shown, the rear central surface 53 can be oriented relative to the front central surface 49 such that the angle between these surfaces is 0° to 15°, preferably about 9°. Furthermore, the tilt angle of the rear central surface 53 relative to the generally longitudinal axis "A" can be about 5° to 25°, preferably 14°. The slope of the rear central surface 53 facilitates the insertion of the symmetrical nose portion 27 into the symmetrical nasal cavity 127 of the tooth tip 14. FIG. 27 In the middle, the width of the central surface 53 then restricts the twisting of the tooth tip 14 after it is mounted on the symmetrical nose 27.

[0109] like FIG. 17 As illustrated, the rear inclined surface 54 may include a generally planar triangular front bowtie surface 55 and a generally planar triangular rear bowtie surface 56, the two surfaces oriented with their vertices pointing towards each other. The front bowtie surface 55 provides the advantage of acting as the primary wedge surface during push-in loading. For example, as FIG. 15 As shown, the front bowtie-shaped surface 55 can be inclined relative to the front inclined surface 50 as it extends in the rearward direction R. For example, the front bowtie-shaped surface 55 can be oriented relative to the front inclined surface 50 such that the angle between the two surfaces is 15° to 27.5°, preferably about 21.5°. Furthermore, for example, as... FIG. 16As shown, the front bowtie-shaped surface 55 may be inclined toward the side surface 60 as it extends from the rear center surface 53 in the lateral direction (e.g., along the +B and -B directions). For example, the front bowtie-shaped surface 55 may be oriented relative to the rear center surface 53 such that the angle between the two surfaces is 17.5° to 32.5°, preferably about 25°.

[0110] For example, such as FIG. 15 and FIG. 17 As shown, the rear bowtie surface 56 may be inclined toward the side surface 60 as it extends from the rear center surface 53 in the lateral direction (e.g., along the +B and -B directions). The inclination angle between the rear bowtie surface 56 and the rear center surface 53 may differ from the inclination angle between the front bowtie surface 55 and the rear center surface 53. More specifically, the inclination angle between the rear bowtie surface 56 and the rear center surface 53 may be greater than the inclination angle between the front bowtie surface 55 and the rear center surface 53. For example, the rear bowtie surface 56 may be oriented relative to the rear center surface 53 such that the angle between these surfaces is 30° to 45°, preferably about 37.5°. Furthermore, as the rear bowtie surface 56 extends rearward from the front bowtie surface 55, the rear bowtie surface 56 may be oriented approximately parallel to the generally longitudinal axis "A". Alternatively, when the rear bowtie surface 56 extends rearward from the front bowtie surface 55, the rear bowtie surfaces 56 may be angularly distant from each other in the vertical direction, but the angle relative to the approximate longitudinal axis "A" is shallower than the angle of the front bowtie surface 55. For example, the rear bowtie surface 56 may be oriented relative to the front bowtie surface 55 such that the angle between the two surfaces is 18.5° to 30°, preferably about 24.5°. The relative surface angles of the front inclined surface 50, the front bowtie surface 55, and the rear bowtie surface 56 provide the advantage of wedging the tooth tip 14 into the symmetrical nose 27, especially during front loading, reducing the overall movement of the tooth tip 14 and dispersing stress and wear through the symmetrical nose 27.

[0111] like FIG. 17 As illustrated, the front portion 48 of the top surface 46 and the bottom surface 66 of the symmetrical nose 27, the rear portion 52 of the top surface 46 and the bottom surface 46 of the symmetrical nose 27, and the middle portion 24 of the adapter 12 may each be separated by a transition portion 51, which may include one or more curved surfaces that transition between relative angles of otherwise adjacent, generally planar surfaces. Individually defined surfaces within the front portion 48 and the rear portion 52 of the top and bottom surfaces 46 (e.g., the front center surface 49 and the rear center surface 53, the front lateral inclined surface 50, and the front bowtie surface 55 and the rear bowtie surface 56) may also be separated by the transition portion 51.

[0112] like FIG. 15As shown, the side surfaces 60 of the symmetrical nose portion 27 may be generally planar and extend between the top surface 46 and the bottom surface 66. The side surfaces 60 may include: a generally planar front side surface 61 disposed close to the front surface 36; a generally planar middle side surface 62 extending rearward from the front side surface 61; and a rear side surface 63 extending rearward from the middle side surface to the middle portion 24 of the adapter 12. The front side surfaces 61 may be longitudinally aligned such that they separate the front inclined surfaces 50 of the top and bottom surfaces 46. The middle side surfaces 62 may be longitudinally aligned such that they separate the front bowtie-shaped surfaces 55 of the top and bottom surfaces 46. The rear side surfaces 63 may be longitudinally aligned such that they separate the rear bowtie-shaped surfaces 56 of the top and bottom surfaces 46.

[0113] like FIG. 17 As shown, the front side surface 61 and the middle side surface 62 can be parallel and continuous as they extend rearward from the side edge 38 of the front surface 36. The front side surface 61 and the middle side surface 62 can be oriented relative to the front surface 36 such that the angle between these surfaces is 90° to 105°, preferably about 93°. Furthermore, as... FIG. 15 As shown, the front surface 61 can be configured such that the distance between the top surface 46 and the bottom surface 66 is approximately constant as the front surface 61 extends rearward from the side edge 38. Alternatively, the front surface 61 can be configured such that the distance between the top surface 46 and the bottom surface 66 increases slightly as the front surface 61 extends rearward from the side edge 38. The intermediate side surface 62 can be configured such that the distance between the top surface 46 and the bottom surface 66 increases significantly as the intermediate side surface 62 extends rearward.

[0114] like FIG. 17 As shown, as the rear side surfaces 63 extend rearward from the intermediate side surface 62, they may be inclined outward relative to the front side surface 61 and the intermediate side surface 62 (e.g., along the +B and -B directions), such that the lateral distance between the rear side surfaces 63 increases symmetrically as the rear side surfaces 63 extend rearward. For example, the rear side surfaces 63 may be inclined outward relative to the intermediate side surface 62 at an angle greater than 0° to 15°, preferably at an angle of about 7°. An angle greater than 0° provides the following advantages: allowing the rear side surfaces 63 to act as wedge surfaces during push-in loading; increasing the contact surface between the adapter 12 and the tooth tip 14 during operation, and thus reducing slippage and wear; and improving removability during removal by reducing friction between the adapter 12 and the tooth tip 14. Alternatively, in some exemplary embodiments, the rear side surfaces 63 may be generally parallel to the intermediate side surface 62. In some exemplary embodiments, the rear side surfaces 63 may be configured such that the distance between the top surface 46 and the bottom surface 66 decreases slightly as the rear side surfaces 63 extend rearward.

[0115] The front side surface 61, middle side surface 62, rear side surface 63, top surface and bottom surface 46 of the side surface 60 of the symmetrical nose 27 and the middle portion 24 of the adapter 12 may be separated by a transition portion 51, which may include one or more curved surfaces that transition between relative angles of originally adjacent, normally planar surfaces. FIG. 40 Examples FIG. 12 The front view of adapter 12, and FIG. 41 Examples are shown along FIG. 40 The vertical cross-sectional view of adapter 12 taken by the JJ line is shown. FIG. 41 It also shows examples of... FIG. 12 The adapter 12 is associated with the symmetrical nose 27 and some of the surfaces discussed above.

[0116] like FIG. 15 As shown, the vertical height (“RVH”) at the rear of the symmetrical nose 27 (at the vertical plane “P”) can be 0.5 to 1.0 times the longitudinal length (“LL”) of the symmetrical nose 27, where the longitudinal length (“LL”) is defined as the distance from the vertical plane “P” to the front surface 36 along the approximately longitudinal axis “A”. The vertical height (“FVH”) at the front of the symmetrical nose 27 (at the front surface 36) can be 0.2 to 0.5 times the longitudinal length (“LL”) of the symmetrical nose 27. FIG. 17 As shown, the lateral width (“RTW”) at the rear of the symmetrical nose 27 (at vertical plane “P”) can be 0.8 to 2.0 times the lateral width (“FTW”) at the front of the symmetrical nose 27 (at front surface 36). The lateral width (“FTW”) at the front of the symmetrical nose 27 (at front surface 36) can be 0.4 to 1.5 times the longitudinal length (“LL”) of the symmetrical nose 27. The longitudinal length (“LL”) of the symmetrical nose 27 can be 0.7 to 2.0 times the lateral width (“RTW”) at the rear of the symmetrical nose 27 (at vertical plane “P”).

[0117] FIG. 42 Examples are shown with cross-section lines KK, LL, and MM. FIG. 12 Side view of adapter 12. (See attached image.) FIG. 42 As illustrated, the sections corresponding to the KK line, LL line and MM line can be located at distances of approximately 0.1X, 0.4X, 0.8X and 1.0X from the anterior surface 36 of the symmetrical nose 27. FIG. 43 Examples are shown along such FIG. 42 A cross-sectional view of the symmetrical nose 27 of the KK line shown. (See attached image.) FIG. 43As illustrated, the front center surface 49 may be positioned between two generally planar, opposing front inclined surfaces 50, which are inclined laterally (e.g., along the +B and -B directions) away from the front center surface 49 toward the side surface 60. The front inclined surfaces 50 may be oriented relative to the front center surface 49 such that these surfaces form an angle of 18.5° to 30°, preferably about 24.5°. FIG. 44 Examples are shown along such FIG. 42 A cross-sectional view of the symmetrical nose 27 of the LL line shown. (See figure) FIG. 44 As illustrated, the front bowtie-shaped surface 55 may be inclined toward the side surface 60 as it extends from the rear center surface 53 in the lateral direction (e.g., along the +B and -B directions). For example, the front bowtie-shaped surface 55 may be oriented relative to the rear center surface 53 such that the angle between the two surfaces is 17.5° to 32.5°, preferably about 25°.

[0118] FIG. 45 Examples are shown along such FIG. 42 A cross-sectional view of the symmetrical nose 27 of the MM line shown. (See figure) FIG. 45 As illustrated, the rear bowtie surface 56 may be inclined toward the side surface 60 as it extends laterally from the rear center surface 53 (e.g., along the +B and -B directions). The inclination angle between the rear bowtie surface 56 and the rear center surface 53 may differ from the inclination angle between the front bowtie surface 55 and the rear center surface 53. More specifically, the inclination angle between the rear bowtie surface 56 and the rear center surface 53 may be greater than the inclination angle between the front bowtie surface 55 and the rear center surface 53. For example, the rear bowtie surface 56 may be oriented relative to the rear center surface 53 such that the angle between these surfaces is 30° to 45°, preferably about 37.5°.

[0119] The tooth tip corresponding to the asymmetric adapter ( FIG. 18 to FIG. 25 and FIG. 46 to FIG. 49 )

[0120] FIG. 18 and FIG. 19 Examples of the same FIG. 4 Isometric view of the tip 14 corresponding to the nose 26 of the adapter 12. FIG. 18 to FIG. 25 and FIG. 46 to FIG. 49 The tooth tip 14 corresponding to the nose 26 of adapter 12 is shown in more detail. (Reference) FIG. 18The tooth tip 14 may generally be wedge-shaped and have a rear edge 90. The tooth tip may have a top outer surface 92 extending forward (e.g., in the F direction) from the top edge 91 of the rear edge 90, and a bottom outer surface 94 extending forward from the bottom edge 93 of the rear edge 90. The top outer surface 92 may be inclined downward (e.g., in the D direction) relative to the rear edge 90, and the bottom outer surface 94 may be inclined upward (e.g., in the U direction), such that the top outer surface 92 and the bottom outer surface 94 converge at a front edge 96 at the front of the tooth tip 14. The tooth tip 14 also includes lateral outer surfaces 98 extending between the top outer surface 92 and the bottom outer surface 94 on both sides of the tooth tip 14. Each of the lateral outer surfaces 98 may have a corresponding retaining hole 16 into which a retaining mechanism 13 (not shown) may be inserted to secure the tooth tip 14 in the appropriate position on the nose 26 of the adapter 12 (e.g., ...). FIG. 3 (As shown). The retaining hole 16 may include, for example, a through hole configured to receive the retaining mechanism 13. The retaining hole 16 may also include a ramped surface, an alignment groove, a thread, and / or an internal groove. Alternative configurations of the outer surfaces 92, 94, 98 and edges 90, 96 of the tooth tip 14 will be compatible with embodiments of the adapter 12 for the tooth tip assembly 10 according to the present disclosure described above. It is also contemplated that the tooth tip assembly 10 according to the present disclosure is not limited to any particular configuration of the outer surfaces and edges of the tooth tip 14.

[0121] like FIG. 19 As shown, the tooth tip 14 can be configured to be received on the nose portion 26 of the adapter 12. A nasal cavity 126 can be defined within the tooth tip 14. The nasal cavity 126 can have a complementary configuration relative to the nose portion 26 of the adapter 12 and can include a bottom inner surface 166, a top inner surface 146, a pair of opposing side inner surfaces 160 extending between the top inner surface 146 and the bottom inner surface 166, and a front inner surface 136.

[0122] FIG. 20 Examples are shown along FIG. 18 A side view of the vertical cross-section of tooth tip 14 taken by the NN line. FIG. 21 Examples are shown along FIG. 18 An enlarged view of the vertical cross-sectional side view of the tooth tip 14, taken by the NN line, showing the nasal cavity 126. (See image) FIG. 20 and FIG. 21As shown, the anterior inner surface 136 of the nasal cavity 126 may be planar or may include a degree of curvature. As illustrated in the example embodiment, the anterior inner surface 136 may be oriented approximately perpendicular to a generally longitudinal axis “H,” the orientation of which is defined as being centered between opposing lateral inner surfaces 160 of the nasal cavity 126 and between the top outer surface 92 and bottom outer surface 94 of the tooth cusp 14. Alternatively, the anterior inner surface 136 may extend upward from the bottom inner surface 166 at an angle of 1° to 5° away from the rear edge 90, or at an angle of 1° to 15° toward the rear edge 90.

[0123] FIG. 22 yes FIG. 18 Rear view of tooth tip 14. (See example) FIG. 22 As shown, the front inner surface 136 may be hexagonal, including a bottom inner edge 137, a opposing side inner edge 138 oriented at approximately 90° relative to the bottom inner edge 137, a top horizontal inner edge 139 oriented approximately parallel to the bottom inner edge 137, and a opposing top inclined inner edge 140 connecting the top horizontal inner edge 139 to the side inner edge 138. The angle between the top horizontal inner edge 139 and the top inclined inner edge 140 is approximately 18.5° to 30°, preferably approximately 24.5°. The inner edges 137 to 140 may be curved.

[0124] FIG. 23 Examples are shown along FIG. 18 Bottom view of the horizontal cross-section of tooth tip 14 taken by the OO line. FIG. 24 Examples are shown along FIG. 18 An enlarged view of the bottom horizontal cross-section of the tooth tip 14, taken by the OO line, showing the nasal cavity 126. (See image below.) FIG. 23 and FIG. 24 As shown, the top inner surface 146 of the nose cavity 126 can be configured to support the tooth tip 14 during use of the loader bucket assembly 1 or the excavator bucket assembly 6, and to facilitate holding the tooth tip 14 on the nose 26 when carrying a load of work material. FIG. 24As shown, the top inner surface 146 may include a front inner portion 148 disposed near the front inner surface 136, a rearward (e.g., in the R direction) transition portion 151, and a rear portion 152 extending rearward from the transition portion 151 toward a rearward edge 90. The front inner portion 148 may include a generally planar front central inner surface 149 extending rearward from the top horizontal inner edge 139 of the front inner surface 136 and situated between two generally planar, opposing front inclined inner surfaces 150 extending rearward from the top inclined inner edge 140 of the front inner surface 136 and sloping downward in the lateral direction (e.g., along the +B and -B directions) away from the front central inner surface 149. As the front central inner surface 149 extends rearward from the top horizontal inner edge 139, the lateral width of the front central inner surface 149 (e.g., along the +B and -B directions) may decrease symmetrically, resulting in the front central inner surface 149 having a shape similar to an isosceles trapezoid, such as... FIG. 24 As illustrated in the example embodiment. Alternatively, the lateral width of the front center inner surface 149 may be constant, or it may increase as the front center inner surface 149 extends rearward from the top horizontal inner edge 139.

[0125] like FIG. 21 As shown, the front central inner surface 149 may extend upward (e.g., in the U direction) away from the top horizontal inner edge 139, such that the front central inner surface 149 and the front inner surface 136 form an angle of 91° to 105°, preferably about 95°. Alternatively, the front central inner surface 149 may extend substantially perpendicular to the front inner surface 136, for example, forming an angle of 88° to 92°, preferably 90°. Alternatively, the front central inner surface 149 may extend at an acute angle relative to the front inner surface 136, for example, forming an angle of 85° to 89°. The front lateral inclined inner surface 150 may be oriented relative to the front central inner surface 149, such that the two surfaces form an angle of 18.5° to 30°, preferably about 24.5°. The front lateral inclined inner surface 150 provides stability to the tooth tip assembly 10 during upward and lateral loading modes, for example, by acting as a wedge-shaped surface to reduce relative movement between the nose 26 of the adapter 12 and the nasal cavity 126 of the tooth tip 14. The front inclined inner surface 150 additionally increases the contact area between the nose 26 of the adapter 12 and the nasal cavity 126 of the tooth tip 14, thereby reducing stress throughout the nose 26. Furthermore, when a load is applied to the tooth tip assembly 10, the front inclined inner surface 150 additionally increases friction, thereby reducing the load on the tooth tip 14 and the retaining mechanism 13, especially when combined with other laterally inclined surfaces (e.g., the channel side surface 180 described below).

[0126] Back FIG. 24The rear portion 152 of the top inner surface 146 may include a generally planar rear central inner surface 153 extending from near the front central inner surface 149 toward the rear edge 90 and situated between two opposing rearwardly inclined inner surfaces 154, which in turn extend rearward from the frontwardly inclined inner surface 150 and are inclined laterally away from the rear central inner surface 153 (e.g., along the +B and -B directions). The rearwardly inclined inner surfaces 154 serve to provide increased stability; for example, during downward and lateral loading of the tooth tip assembly 10, these surfaces reduce relative movement between the nose 26 and the tooth tip 14 and increase the contact area by acting as wedge-shaped surfaces. Furthermore, the increased contact area provided by the rearwardly inclined inner surfaces 154 reduces stress on the nose 26.

[0127] As the posterior central inner surface 153 extends posteriorly from the anterior central inner surface 149, the lateral width of the posterior central inner surface 153 (e.g., along the +B and -B directions) may first increase and then decrease. In some embodiments, the width of the posterior central inner surface 153 near the anterior central inner surface 149 is equal to the width of the nasal cavity 126 (as shown in...). FIG. 23 The width of the posterior central inner surface 153 at its widest point extending posteriorly from the anterior central inner surface 149 is 0.1 to 0.4 times, preferably about 0.23 times, the posterior central inner surface 153 at its widest point is 0.6 to 0.9 times, preferably about 0.73 times, the posterior central inner surface 153 at its widest point is 0.3 to 0.6 times, preferably about 0.46 times, the posterior central inner surface 153 near the posterior edge 90 is 0.3 to 0.6 times, preferably about 0.46 times, the posterior central inner surface 153 at its posterior edge 90. FIG. 21 As illustrated, the rear center inner surface 153 may be inclined upward relative to the front center inner surface 149. The different angles of the front center inner surface 149 and the rear center inner surface 153 relative to the generally longitudinal axis "H" provide the advantage of generating friction on the front center inner surface 149, thereby transferring the load from the retaining mechanism 13 to the nose 26 of the adapter 12. For example, as FIG. 21 As shown, the rear central inner surface 153 can be oriented relative to the front central inner surface 149 such that the angle between the two surfaces is 0° to 15°, preferably about 9°. Furthermore, the angle of inclination of the rear central inner surface 153 relative to the generally longitudinal axis "H" can be about 5° to 25°, preferably 14°. The slope of the rear central inner surface 153 facilitates the insertion of the nose portion 26 into the nasal cavity 126 of the tooth tip 14, while the width of the rear central inner surface 153 restricts the twisting of the tooth tip 14 after it is mounted on the nose portion 26.

[0128] like FIG. 24As illustrated, the rear-side inclined inner surface 154 may include a generally planar triangular front bowtie-shaped inner surface 155 and a generally planar triangular rear bowtie-shaped inner surface 156, the two surfaces oriented with their vertices pointing towards each other. The front bowtie-shaped inner surface 155 provides the advantage of acting as a primary wedge-shaped surface during push-in loading. For example, as FIG. 21 As shown, the front bowtie-shaped inner surface 155 may extend rearward away from the generally longitudinal axis "H" (e.g., in the U direction). For example, the front bowtie-shaped inner surface 155 may be oriented relative to the front inclined inner surface 150 such that the angle between the two surfaces is 15° to 27.5°, preferably about 21.5°. Furthermore, for example, as... FIG. 22 As shown, the front bowtie-shaped inner surface 155 may be inclined downward as it extends from the rear center inner surface 153 in the lateral direction (e.g., the +B and -B directions). For example, the front bowtie-shaped inner surface 155 may be oriented relative to the rear center inner surface 153 such that the angle between the two surfaces is 17.5° to 32.5°, preferably about 25°.

[0129] For example, such as FIG. 21 and FIG. 22 As shown, the rear bowtie-shaped inner surface 156 may slope downwards as it extends from the rear center inner surface 153 in the lateral direction (e.g., along the +B and -B directions). The angle of inclination between the rear bowtie-shaped inner surface 156 and the rear center inner surface 153 may differ from the angle of inclination between the front bowtie-shaped inner surface 155 and the rear center inner surface 153. More specifically, the angle of inclination between the rear bowtie-shaped inner surface 156 and the rear center inner surface 153 may be greater than the angle of inclination between the front bowtie-shaped inner surface 155 and the rear center inner surface 153. For example, the rear bowtie-shaped inner surface 156 may be oriented relative to the rear center inner surface 153 such that the angle between the two surfaces is 30° to 45°, preferably about 37.5°. Furthermore, as the rear bowtie-shaped inner surface 156 extends rearward from the front bowtie-shaped inner surface 155, the rear bowtie-shaped inner surface 156 may be oriented approximately parallel to the generally longitudinal axis "H". Alternatively, when the rear bowtie inner surface 156 extends rearward from the front bowtie inner surface 155, the rear bowtie inner surface 156 may be inclined upward, but at a shallower angle relative to the generally longitudinal axis "H" than the angle of the front bowtie inner surface 155. For example, the rear bowtie inner surface 156 may be oriented relative to the front bowtie inner surface 155 such that the angle between the two surfaces is 18.5° to 30°, preferably about 24.5°. The relative surface angles of the front inclined inner surface 150, the front bowtie inner surface 155, and the rear bowtie inner surface 156 provide the advantage of wedging the tooth tip 14 into the nose 26, especially during front loading, reducing the overall movement of the tooth tip 14 and dispersing stress and wear through the nose cavity 126.

[0130] like FIG. 24As illustrated, the anterior inner portion 148 of the inner top surface 146 of the nasal cavity 126, the posterior portion 152 of the inner top surface 146 of the nasal cavity 126, and the posterior edge 90 may each be separated by an inner transition portion 151, which may include one or more curved surfaces that transition between relative angles of otherwise adjacent, generally planar surfaces. Individually defined surfaces within the anterior inner portion 148 and the posterior portion 152 of the inner top surface 146 (e.g., the anterior central inner surface 149 and the posterior central inner surface 153, the anteriorly inclined inner surface 150, and the anterior bowtie-shaped inner surface 155 and the posterior bowtie-shaped inner surface 156) may also be separated by the inner transition portion 151.

[0131] FIG. 25 Examples are shown along FIG. 18 A top view of the horizontal cross-section of tooth tip 14 taken from the PP line. FIG. 25 Examples are shown along FIG. 18 An enlarged top view of the horizontal cross-section of the tooth tip 14 taken by the PP line, showing the nasal cavity 126. (As in...) FIG. 25 and FIG. 26 As can be seen, the bottom inner surface 166 may include a generally planar front portion 168 disposed near and extending rearward (e.g., along the R direction) from the front inner surface 136, a transition portion 151 extending rearward from the front portion 168, and a rear portion 170 extending rearward from the transition portion 151 toward the rear edge 90 of the tooth tip 14. The front portion 168 provides a flat and stable surface as the primary contact area during loading, which has the advantage of reducing wear on the tooth tip assembly 10. FIG. 21 As shown, the front portion 168 can be oriented at an angle of 85° to 105° relative to the front inner surface 136, preferably at an angle of about 90°. Furthermore, the front portion 168 can be oriented at an angle of 0° to 15° relative to the front central inner surface 149, preferably at an angle of about 5°. This orientation of the front portion 168 provides the advantage of increased friction between the tooth tip 14 and the adapter 12, thereby reducing slippage, for example, when the tooth tip 14 is loaded in the upward direction, resulting in a reduction in load on the retaining mechanism 13.

[0132] Back FIG. 21 and FIG. 26 The rear portion 170 of the inner bottom surface 166 may include: an opposing, generally planar inner shoulder surface 172 that slopes downward (e.g., in...). FIG. 21 (in the direction of D) or alternatively parallel to the front portion 168; and bottom channel 174 (see FIG. 26 The bottom channel slopes downward relative to both the front portion 168 and the inner shoulder surface 172 (e.g., in...). FIG. 21 (in the direction of D). For example FIG. 21As shown, the inner shoulder surface 172 may be oriented downward relative to the front portion 168 at an angle of 0° to 10° (e.g., in the D direction), preferably at an angle of about 4°.

[0133] As in FIG. 26 As can be seen, the bottom channel 174 of the bottom inner surface 166 may include a downward slope relative to the front portion 168 (e.g., in the D direction, see...). FIG. 21 The generally planar front passage portion 176, and the portion that slopes downward relative to the front passage portion 176 (e.g., in the D direction, see...). FIG. 21 The rear passage portion 178 is typically planar. The front passage portion 176 and the rear passage portion 178 may extend between opposing passage side surfaces 180. The bottom passage 174 provides advantages such as increased stability during side loading and increased wedging during push-in loading. FIG. 21 As shown, the front channel portion 176 can be oriented relative to the front portion 168 such that the angle between the two surfaces is 6° to 18°, preferably about 12.5°. The rear channel portion 178 can be oriented relative to the front channel portion 176 such that the angle between the two surfaces is 0° to 15°, preferably 6°. For example, the different angles of the front channel portion 176 and the rear channel portion 178 provide the benefits of reducing relative movement between the adapter 12 and the tooth tip 14, reducing wear, and distributing stress more evenly.

[0134] As in FIG. 26As can be seen, the channel side surface 180 of the bottom channel 174 may include a front channel side surface 181 and a rear channel side surface 182. The front channel side surface 181 connects the front channel portion 176 to the inner shoulder surface 172. The rear channel side surface 182 connects the rear channel portion 178 to the inner shoulder surface 172. The front channel side surfaces 181 of the bottom channel 174 may be generally parallel to each other, such that the lateral width of the front channel portion 176 (e.g., along the +B and -B directions) is generally constant as the front channel portion 176 extends rearward. Alternatively, the front channel side surfaces 181 of the bottom channel 174 may be oriented relative to each other, such that the distance between the front channel side surfaces 181 decreases approximately symmetrically with a longitudinal taper angle "LTA" of 0° to 20° relative to a longitudinal line oriented parallel to the generally longitudinal axis "H". Furthermore, the rear passage side surfaces 182 of the bottom passage 174 may be generally parallel to each other, such that the lateral width of the rear passage portion 178 (e.g., along the +B and -B directions) remains generally constant as the rear passage portion 178 extends rearward. Alternatively, the rear passage side surfaces 182 of the bottom passage 174 may be oriented relative to each other such that the distance between the rear passage side surfaces 182 decreases approximately symmetrically with a longitudinal taper angle "LTA" of 0° to 20°, preferably 5°, relative to a longitudinal line oriented parallel to the generally longitudinal axis "H". The orientation of the passage side surfaces 180 relative to the generally longitudinal axis "H" provides the advantage of increased wedging, thereby reducing relative movement, including reduced lateral pivoting, and reduced wear during push-in loading and downward loading. Figure 22 As shown, the channel side surfaces 180 of the bottom channel 174 can be oriented relative to each other such that the distance between the channel side surfaces 180 decreases approximately symmetrically with a vertical taper angle “VTA” of 30° to 50°, preferably about 39.5°, relative to the vertical line. Furthermore, the channel side surfaces 180 can be oriented relative to the inner shoulder surface 172 such that the angle between these two surfaces is 40° to 60°, preferably about 50.5°. This orientation of the channel side surfaces 180 provides the following advantages: increased stability during side loading; reduced nose volume; enhanced strength; and an additional wedging effect that increases contact area and reduces sliding motion and associated wear.

[0135] like Figure 26 As shown, the anterior portion 168 of the bottom inner surface 166 of the nasal cavity 126, the posterior portion 170 of the top inner surface 166 of the nasal cavity 126, and the posterior edge 90 are each separated by an inner transition portion 151, which may include one or more curved surfaces that transition between relative angles of otherwise adjacent, generally planar surfaces. Individually defined surfaces within the posterior portion 170 of the bottom inner surface 166 (e.g., the inner shoulder surface 172, the anterior channel portion 176, the posterior channel portion 178, and the channel side surface 180) may also be separated by the inner transition portion 151.

[0136] like Figure 20 and Figure 21 As shown, the lateral inner surface 160 of the nasal cavity 126 may be generally planar and extends between the bottom inner surface 166 and the top inner surface 146. The lateral inner surface 160 may include: a generally planar anterior inner surface 161 disposed adjacent to the anterior inner surface 136; a generally planar intermediate inner surface 162 extending rearward (e.g., in the R direction) from the anterior inner surface 161; and a posterior inner surface 163 extending rearward from the intermediate inner surface to the posterior edge 90 of the tooth cusp 14. The anterior inner surface 161 may be longitudinally aligned such that the anterior inclined inner surface 150 of the top inner surface 146 is spaced from the anterior portion 168 of the bottom inner surface 166. The intermediate inner surface 162 may be longitudinally aligned such that the front bowtie-shaped inner surface 155 of the top inner surface 146 is spaced from the inner shoulder surface 172 of the bottom inner surface 166. The rear inner surface 163 can be longitudinally aligned so that the back collar knot-shaped inner surface 156 of the top inner surface 146 is separated from the inner shoulder surface 172 of the bottom inner surface 166.

[0137] like Figure 24 As shown, the front inner surface 161 and the middle inner surface 162 can be parallel and continuous as they extend rearward from the inner side edge 138 of the front inner surface 136. The front inner surface 161 and the middle inner surface 162 can be oriented relative to the front inner surface 136 such that the angle between these surfaces is 90° to 105°, preferably about 93°. Furthermore, as... Figure 21 As shown, the front inner surface 161 can be configured such that the distance between the top inner surface 146 and the bottom inner surface 166 is substantially constant as the front inner surface 161 extends rearward (e.g., in the R direction). Alternatively, the front inner surface 161 can be configured such that the distance between the top inner surface 146 and the bottom inner surface 166 increases slightly as the front inner surface 161 extends rearward. The middle inner surface 162 can be configured such that the distance between the top inner surface 146 and the bottom inner surface 166 increases significantly as the middle inner surface 162 extends rearward.

[0138] like Figure 24As shown, as the rear inner surfaces 163 extend rearward from the intermediate inner surface 162, they may be inclined outward relative to the front inner surface 161 and the intermediate inner surface 162 (e.g., along the +B and -B directions), such that the lateral distance between the rear inner surfaces 163 increases symmetrically as the rear inner surfaces 163 extend rearward. For example, the rear inner surfaces 163 may be inclined outward relative to the intermediate inner surface 162 at an angle of 0° to 15°, preferably at an angle of about 7°. An angle greater than 0° provides the following advantages: allowing the rear inner surfaces 163 to act as a wedge-shaped surface during push-in loading; increasing the contact surface between the adapter 12 and the tooth tip 14 during operation, and thus reducing slippage and wear; and improving removability during removal by reducing friction between the adapter 12 and the tooth tip 14. Alternatively, the rear inner surfaces 163 may be oriented generally parallel to the intermediate inner surface 162. The rear inner surface 163 can be configured such that the distance between the top inner surface 146 and the bottom inner surface 166 decreases slightly as the rear inner surface 163 extends rearward.

[0139] The anterior inner surface 161, the middle inner surface 162, the posterior inner surface 163, the top inner surface 146, the bottom inner surface 166, and the posterior edge 90 of the tooth tip 14 of the lateral inner surface 160 of the nasal cavity 126 may each be separated by an inner transition portion 151, which may include one or more curved surfaces that transition between relative angles of originally adjacent, generally planar surfaces.

[0140] like Figure 20 As shown, the vertical height (“RVH”) at the posterior portion of the nasal cavity 126 (at the vertical plane “P”) can be 0.5 to 1.0 times the longitudinal length (“LL”) of the nasal cavity 126, where the longitudinal length (“LL”) is defined as the distance along the approximately longitudinal axis “A” from the vertical plane “P” to the anteroinner surface 136. The vertical height (“FVH”) at the anterior portion of the nasal cavity 126 (at the anteroinner surface 136) can be 0.2 to 0.5 times the longitudinal length of the nasal cavity 126. Figure 23 and Figure 25 As shown, the posterior transverse width (“RTW”) of the nasal cavity 126 (at the vertical plane “P”) can be 0.8 to 2.0 times the anterior transverse width (“FTW”) of the nasal cavity 126 (at the anteroinner surface 136). The anterior transverse width (“FTW”) of the nasal cavity 126 (at the anteroinner surface 136) can be 0.4 to 1.5 times the longitudinal length (“LL”) of the nasal cavity 126. The longitudinal length (“LL”) of the posterior transverse width (“RTW”) of the nasal cavity 126 (at the vertical plane “P”) can be 0.7 to 2.0 times.

[0141] Figure 46Examples are shown with cross-section lines TT, UU, and VV. Figure 18 A side view of the vertical cross-section of the tooth tip along the NN line. (e.g.) Figure 46 As illustrated, the cross sections corresponding to the TT line, UU line and VV line can be located at distances of approximately 0.1X, 0.4X and 0.8X from the anterior inner surface 136 of the nasal cavity 126. Figure 47 Examples are shown along such Figure 46 A cross-sectional view of the nasal cavity 126 of the TT line is shown. Figure 47 As illustrated, the front inner surface 136 may be hexagonal, including a bottom inner edge 137, an opposing side inner edge 138 oriented at approximately 90° relative to the bottom inner edge 137, a top horizontal inner edge 139 oriented approximately parallel to the bottom inner edge 137, and an opposing top inclined inner edge 140 connecting the top horizontal inner edge 139 to the side inner edge 138. The angle between the top horizontal inner edge 139 and the top inclined inner edge 140 is approximately 18.5° to 30°, preferably approximately 24.5°. The inner edges 137 to 140 may be curved.

[0142] Figure 48 Examples are shown along such Figure 46 A cross-sectional view of the nasal cavity 126 shown in the UU line. Figure 48 As illustrated, a generally planar rear central inner surface 153 may be arranged between two opposing rear inclined inner surfaces 154, which are inclined away from the rear central inner surface 153 in the lateral direction (e.g., the +B and -B directions). The rear central inner surface 153 may be oriented relative to the front central inner surface 149 such that the angle between the two surfaces is 0° to 15°, preferably about 9°. Figure 49 Examples are shown along such Figure 46 A cross-sectional view of the nasal cavity 126 shown in the VV line. (See attached image.) Figure 49 As illustrated, the normally planar triangular front bowtie-shaped inner surface 155 and the normally planar triangular back bowtie-shaped inner surface 156 can be oriented with their vertices pointing towards each other. Furthermore, for example, as... Figure 22As shown, the front bowtie-shaped inner surface 155 may slope downwards as it extends from the rear center inner surface 153 in the lateral direction (e.g., along the +B and -B directions). For example, the front bowtie-shaped inner surface 155 may be oriented relative to the rear center inner surface 153 such that the angle between the two surfaces is 17.5° to 32.5°, preferably about 25°. The rear bowtie-shaped inner surface 156 may slope downwards (e.g., in the D direction) as it extends from the rear center inner surface 153 in the lateral direction (e.g., along the +B and -B directions). The angle of inclination between the rear bowtie-shaped inner surface 156 and the rear center inner surface 153 may differ from the angle of inclination between the front bowtie-shaped inner surface 155 and the rear center inner surface 153. More specifically, the angle of inclination between the rear bowtie-shaped inner surface 156 and the rear center inner surface 153 may be greater than the angle of inclination between the front bowtie-shaped inner surface 155 and the rear center inner surface 153. For example, the inner surface 156 of the back bow tie shape may be oriented relative to the inner surface 153 of the back center, such that the angle between the two surfaces is 30° to 45°, preferably about 37.5°.

[0143] The tooth tip corresponding to the symmetrical adapter ( Figures 27 to 32 and Figures 50 to 53 )

[0144] Figures 27 to 32 and Figures 50 to 53 An alternative embodiment of the tooth tip 14 is shown, which includes a symmetrical nasal cavity 127. The symmetrical nasal cavity 127 is configured to receive a corresponding alternative embodiment of the adapter 12, which includes a symmetrical nose 27. Figures 12 to 17 (This will be described more fully below.) The symmetrical nose cavity 127 and the corresponding symmetrical nose 27 provide the following benefits: allowing the user to reverse the top-bottom orientation of the tooth tip 14 when it is attached to the adapter 12, to achieve more uniform wear on the top and bottom surfaces of the tooth tip. Although in Figures 27 to 32 Not shown, but each of the lateral outer surfaces 98 ( Figure 27 The adapter 12 may have a corresponding retaining hole (not shown) in the retaining hole 16, into which a retaining mechanism 13 (not shown) can be inserted to secure the tooth tip 14 in the appropriate position on the symmetrical nose 27 of the adapter 12 (e.g., Figure 3 (As shown). The retaining hole 16 may include, for example, a through hole configured to receive the retaining mechanism 13. The retaining hole 16 may also include a ramped surface, an alignment groove, a thread, and / or an internal groove.

[0145] Figure 27 An isometric view illustrating an alternative embodiment of the tooth tip 14 is shown. Figure 27As shown, the tooth tip 14 can be configured to be received on the symmetrical nose portion 27 of the adapter 12. The symmetrical nose cavity 127 can be defined within the tooth tip 14. The symmetrical nose cavity 127 can have a complementary configuration relative to the symmetrical nose portion 27 of the adapter 12, and can include a pair of opposing top inner surfaces 146 and bottom inner surfaces 166, a pair of opposing side inner surfaces 160 extending between the top inner surfaces 146 and bottom inner surfaces 166, and a front inner surface 136.

[0146] Figure 28 It is along Figure 27 A side view of the vertical cross-section of the tooth tip 14 of the QQ line, and Figure 29 It is along Figure 27 An enlarged view of the vertical cross-sectional side view of the tooth tip 14 of the QQ line, showing the nasal cavity 127. (See image) Figure 28 and Figure 29 As shown, the anterior inner surface 136 of the symmetrical nasal cavity 127 can be planar, or it may include a certain degree of curvature. Figure 28 As shown, the anterior inner surface 136 may be oriented approximately perpendicular to a general longitudinal axis “H”, which is defined as the center located between the opposing lateral inner surfaces 160 of the symmetrical nasal cavity 127 and between the top inner surface 146 and the bottom inner surface 166.

[0147] Figure 30 Examples Figure 27 Rear view of tooth tip 14. (See example) Figure 30 As shown, the front inner surface 136 may be octagonal, including opposing top and bottom horizontal inner edges 139, opposing side inner edges 138 oriented at approximately 90° relative to the top and bottom horizontal inner edges 139, and opposing top and bottom inclined inner edges 140 connecting the top and bottom horizontal inner edges 139 to the side inner edges 138. The angle between the top and bottom horizontal inner edges 139 and the top and bottom inclined edges 140 is approximately 18.5° to 30°, preferably approximately 24.5°. The inner edges 139 to 140 may be curved.

[0148] Figure 31 It is along Figure 27 A top view of the horizontal cross-section of the tooth tip 14 of the SS line, and Figure 30 It is along Figure 27 An enlarged top view of the horizontal cross-section of the tooth tip 14 of the SS line, showing the nasal cavity 127. (See image) Figure 31 and Figure 32As shown, the top inner surface 146 and bottom inner surface 166 of the symmetrical nose cavity 127 can be configured to support the tooth tip 14 during use of the loader bucket assembly 1 or the excavator bucket assembly 6, and to facilitate holding the tooth tip 14 on the symmetrical nose 27 when bearing the load of the workpiece. Figure 32 As shown, the top inner surface 146 and the bottom inner surface 166 may include a front inner portion 148 disposed near the front inner surface 136, a transition portion 151 extending rearward (e.g., in the R direction) from the front inner portion 148, and a rear portion 152 extending rearward from the transition portion 151 toward a rear edge 90. The front portion 148 may include a generally planar front central inner surface 149 extending rearward from the top or bottom horizontal inner edge 139 of the front inner surface 136 and situated between two generally planar, opposing front lateral inclined inner surfaces 150 extending rearward from the top and bottom lateral inclined inner edges 140 of the front inner surface 136 and inclined in a lateral direction (e.g., along the +B and -B directions) away from the front central inner surface 149 toward the side inner surface 160. As the front central inner surface 149 extends rearward from the top horizontal inner edge 139 and the bottom horizontal inner edge 139, the lateral width of the front central inner surface 149 can decrease symmetrically, resulting in the front central inner surface 149 having a shape similar to an isosceles trapezoid, such as... Figure 32 As illustrated in the example embodiment. Alternatively, the lateral width of the front center inner surface 149 may be constant, or it may increase as the front center inner surface 149 extends rearward from the top horizontal inner edge and the bottom horizontal inner edge 139.

[0149] like Figure 29As shown, the front central inner surface 149 may extend rearward away from the generally longitudinal axis "H" (in the U and D directions), such that the front central inner surface 149 and the front inner surface 136 form an angle of 91° to 105°, preferably about 95°. Alternatively, the front central inner surface 149 may extend generally perpendicular to the front inner surface 136, for example, forming an angle of 88° to 92°, preferably 90°. The front lateral inclined inner surface 150 may be oriented relative to the front central inner surface 149, such that these surfaces form an angle of 18.5° to 30°, preferably about 24.5°. The front lateral inclined inner surface 150 provides stability to the tooth tip assembly 10 during downward and lateral loading modes, for example by acting as a wedge-shaped surface to reduce relative movement between the symmetrical nose 27 of the adapter 12 and the symmetrical nose cavity 127 of the tooth tip 14. The front inclined inner surface 150 additionally increases the contact area between the symmetrical nose 27 of the adapter 12 and the symmetrical nose cavity 127 of the tooth tip 14, thereby reducing stress throughout the symmetrical nose 27. Furthermore, when a load is applied to the tooth tip assembly 10, the front inclined inner surface 150 additionally increases friction, thereby reducing the load on the tooth tip 14 and the retaining mechanism 13, especially when combined with other laterally inclined surfaces (e.g., the rear bowtie-shaped inner surface 156 described below).

[0150] Back Figure 32 The rear portion 152 of the top and bottom inner surfaces 146 may include a generally planar rear central inner surface 153 that extends rearward (e.g., in the R direction) toward the rear edge 90 from the transition portion 151. The planar rear central inner surface 153 may also extend between two opposing rearwardly inclined inner surfaces 154 that extend rearward from the transition portion 151 and are inclined laterally (e.g., along the +B and -B directions) away from the rear central inner surface 153. The rearwardly inclined inner surfaces 154 serve to provide increased stability, for example, during upward, downward, and lateral loading of the tooth tip assembly 10, by acting as wedge-shaped surfaces to reduce relative movement between the symmetrical nose 27 and the tooth tip 14 and increase the contact area. Furthermore, the increased contact area provided by the rearwardly inclined inner surfaces 154 reduces stress on the symmetrical nose 27.

[0151] As the posterior central inner surface 153 extends posteriorly from the anterior central inner surface 149, the lateral width of the posterior central inner surface 153 (e.g., along the +B and -B directions) may first increase and then decrease. In some embodiments, the width of the posterior central inner surface 153 near the anterior central inner surface 149 is symmetrical about the nasal cavity 127 (as shown in...). Figure 31The width of the rear lateral width (“RTW”) at the rear of the vertical plane “P” shown is 0.1 to 0.4 times, preferably about 0.23 times. In some embodiments, the width of the rear central inner surface 153 at its widest point as it extends rearward from the front central inner surface 149 is 0.6 to 0.9 times, preferably about 0.73 times, the lateral width (“RTW”) at the rear of the symmetrical nasal cavity 127. In some embodiments, the width of the rear central inner surface 153 near the rear edge 90 is 0.3 to 0.6 times, preferably about 0.46 times, the lateral width (“RTW”) at the rear of the symmetrical nasal cavity 127. The rear central inner surface 153 may extend rearward away from the generally longitudinal axis “H”. The different angles of the front central inner surface 149 and the rear central inner surface 153 relative to the generally longitudinal axis “H” provide the advantage of generating friction on the front central inner surface 149, thereby transferring the load from the retaining mechanism 13 to the symmetrical nose 27 of the adapter 12. For example, as Figure 29 As shown, the rear central inner surface 153 can be oriented relative to the front central inner surface 149 such that the angle formed by these two surfaces is 0° to 15°, preferably about 9°. Furthermore, the angle of inclination of the rear central inner surface 153 relative to the generally longitudinal axis "H" can be about 5° to 25°, preferably 14°. The slope of the rear central inner surface 153 facilitates the insertion of the symmetrical nose portion 27 into the symmetrical nose cavity 127 of the tooth tip 14, while the width of the rear central inner surface 153 restricts the twisting of the tooth tip 14 after it is mounted on the symmetrical nose portion 27.

[0152] like Figure 32 As illustrated, the rear-side inclined inner surface 154 may include a generally planar triangular front bowtie-shaped inner surface 155 and a generally planar triangular rear bowtie-shaped inner surface 156, the two surfaces oriented with their vertices pointing towards each other. The front bowtie-shaped inner surface 155 provides the advantage of acting as a primary wedge-shaped surface during push-in loading. For example, as Figure 32 As shown, the front bowtie-shaped inner surface 155 can extend rearward away from the generally longitudinal axis "H". For example, the front bowtie-shaped inner surface 155 can be oriented relative to the front inclined inner surface 150, such that the angle between the two surfaces is 15° to 27.5°, preferably about 21.5°. Furthermore, for example, as... Figure 30 As shown, the front bowtie-shaped inner surface 155 may be inclined toward the side inner surface 160 as it extends from the rear center inner surface 153 in the lateral directions +B and -B. For example, the front bowtie-shaped inner surface 155 may be oriented relative to the rear center inner surface 153 such that the angle between the two surfaces is 17.5° to 32.5°, preferably about 25°.

[0153] For example, such as Figure 30As shown, the rear bowtie-shaped inner surface 156 may be inclined toward the side inner surface 160 as it extends from the rear center inner surface 153 in the lateral directions +B and -B. The inclination angle between the rear bowtie-shaped inner surface 156 and the rear center inner surface 153 may differ from the inclination angle between the front bowtie-shaped inner surface 155 and the rear center inner surface 153. More specifically, the inclination angle between the rear bowtie-shaped inner surface 156 and the rear center inner surface 153 may be greater than the inclination angle between the front bowtie-shaped inner surface 155 and the rear center inner surface 153. For example, the rear bowtie-shaped inner surface 156 may be oriented relative to the rear center inner surface 153 such that the angle between these surfaces is 30° to 45°, preferably about 37.5°. Furthermore, when the rear bowtie-shaped inner surface 156 extends rearward from the front bowtie-shaped inner surface 155, the rear bowtie-shaped inner surface 156 may be oriented approximately parallel to the generally longitudinal axis "H". Alternatively, when the rear bowtie inner surface 156 extends rearward from the front bowtie inner surface 155, the rear bowtie inner surface 156 may be angled away from the generally longitudinal axis "H", but the angle relative to the generally longitudinal axis "A" is shallower than that of the front bowtie inner surface 155. For example, the rear bowtie inner surface 156 may be oriented relative to the front bowtie inner surface 155 such that the angle between the two surfaces is 18.5° to 30°, preferably about 24.5°. The relative surface angles of the front inclined inner surface 150, the front bowtie inner surface 155, and the rear bowtie inner surface 156 provide the advantage of wedging the tooth tip 14 into the symmetrical nose 27, especially during preloading, reducing the overall movement of the tooth tip 14 and dispersing stress and wear through the symmetrical nose cavity 127.

[0154] like Figure 32 As illustrated, the anterior portion 148 of the top inner surface and bottom inner surface 146 of the symmetrical nasal cavity 127, the posterior portion 152 of the top inner surface and bottom inner surface 146 of the symmetrical nasal cavity 127, and the posterior edge 90 may each be separated by an inner transition portion 151, which may include one or more curved surfaces that transition between relative angles of otherwise adjacent, generally planar surfaces. Individually defined surfaces within the anterior portion 148 and posterior portion 152 of the top inner surface and bottom inner surface 146 (e.g., anterior central inner surface 149 and posterior central inner surface 153, anteriorly inclined inner surface 150, and anterior bowtie-shaped inner surface 155 and posterior bowtie-shaped inner surface 156) may also each be separated by an inner transition portion 151.

[0155] like Figure 28 and Figure 29As shown, the lateral inner surfaces 160 of the symmetrical nasal cavity 127 may be generally planar and extend between the top inner surface and the bottom inner surface 146. The lateral inner surfaces 160 may include: a generally planar anterior inner surface 161 disposed adjacent to the anterior inner surface 136; a generally planar intermediate inner surface 162 extending rearward (e.g., in the R direction) from the anterior inner surface 161; and a posterior inner surface 163 extending rearward from the intermediate inner surface to the posterior edge 90 of the tooth cusp 14. The anterior inner surfaces 161 may be longitudinally aligned such that they separate the anterior inclined inner surfaces 150 of the top and bottom inner surfaces 146. The intermediate inner surfaces 162 may be longitudinally aligned such that they separate the anterior bowtie-shaped inner surfaces 155 of the top and bottom inner surfaces 146. The rear inner surfaces 163 can be longitudinally aligned so that they separate the rear bow tie-shaped inner surfaces 156 of the top inner surface and the bottom inner surface 146.

[0156] like Figure 32 As shown, the front inner surface 161 and the middle inner surface 162 can be parallel and continuous as they extend rearward from the inner edge 138 of the front inner surface 136. The front inner surface 161 and the middle inner surface 162 can be oriented relative to the front inner surface 136 such that the angle between these surfaces is 90° to 105°, preferably about 93°. Furthermore, as... Figure 29 As shown, the front inner surface 161 can be configured such that the distance between the top inner surface 146 and the bottom inner surface 166 is substantially constant as the front inner surface 161 extends rearward from the inner side edge 138. Alternatively, the front inner surface 161 can be configured such that the distance between the top inner surface and the bottom inner surface 146 increases slightly as the front inner surface 161 extends rearward from the inner side edge 138. The middle inner surface 162 can be configured such that the distance between the top inner surface and the bottom inner surface 146 increases significantly as the middle inner surface 162 extends rearward.

[0157] like Figure 32As shown, as the rear inner surfaces 163 extend rearward from the intermediate inner surface 162, they may be inclined outward relative to the front inner surface 161 and the intermediate inner surface 162 (e.g., along the +B and -B directions), such that the lateral distance between the rear inner surfaces 163 (e.g., along the +B and -B directions) increases symmetrically as the rear inner surfaces 163 extend rearward. For example, the rear inner surfaces 163 may be inclined outward relative to the intermediate inner surface 162 at an angle of 0° to 15°, preferably at an angle of about 7°. An angle greater than 0° provides the following advantages: allowing the rear inner surfaces 163 to act as wedge surfaces during push-in loading; increasing the contact surface between the adapter 12 and the tooth tip 14 during operation, and thus reducing slippage and wear; and improving removability during removal by reducing friction between the adapter 12 and the tooth tip 14. Alternatively, the rear inner surfaces 163 may be oriented substantially parallel to the intermediate inner surface 162. The rear inner surface 163 can be configured such that the distance between the top inner surface and the bottom inner surface 146 decreases slightly as the rear inner surface 163 extends rearward.

[0158] The anterior inner surface 161, the middle inner surface 162, the posterior inner surface 163, the top inner surface, and the bottom inner surface 146 of the lateral inner surface 160 of the symmetrical nasal cavity 127, as well as the posterior edge 90 of the tooth tip 14, may each be separated by an inner transition portion 151, which may include one or more curved surfaces that transition between relative angles of originally adjacent, generally planar surfaces.

[0159] like Figure 28 As shown, the vertical height (“RVH”) at the posterior portion of the symmetrical nasal cavity 127 (at the vertical plane “P”) can be 0.5 to 1.0 times the longitudinal length (“LL”) of the symmetrical nasal cavity 127, where the longitudinal length (“LL”) is defined as the distance along the approximately longitudinal axis “A” from the vertical plane “P” to the anteroinner surface 136. The vertical height (“FVH”) at the anterior portion of the symmetrical nasal cavity 127 (at the anteroinner surface 136) can be 0.2 to 0.5 times the longitudinal length of the symmetrical nasal cavity 127. Figure 31 As shown, the posterior transverse width (“RTW”) of the symmetrical nasal cavity 127 (at the vertical plane “P”) can be 0.8 to 2.0 times the anterior transverse width (“FTW”) of the symmetrical nasal cavity 127 (at the anteroinner surface 136). The anterior transverse width (“FTW”) of the symmetrical nasal cavity 127 (at the anteroinner surface 136) can be 0.4 to 1.5 times the longitudinal length (“LL”) of the symmetrical nasal cavity 127. The longitudinal length (“LL”) of the symmetrical nasal cavity 127 can be 0.7 to 2.0 times the posterior transverse width (“RTW”) of the symmetrical nasal cavity 127 (at the vertical plane “P”).

(e.g.) Figure 50 As illustrated, the cross sections corresponding to the WW line, XX line and YY line can be located at distances of approximately 0.1X, 0.4X and 0.8X from the anterior inner surface 136 of the symmetrical nasal cavity 127. Figure 51 Examples are shown along such Figure 50 A cross-sectional view of the symmetrical nasal cavity 127 along the WW line. (See figure) Figure 51 As illustrated, the front inner surface 136 may be hexagonal, including a bottom inner edge 137, an opposing side inner edge 138 oriented at approximately 90° relative to the bottom inner edge 137, a top horizontal inner edge 139 oriented approximately parallel to the bottom inner edge 137, and an opposing top inclined inner edge 140 connecting the top horizontal inner edge 139 to the side inner edge 138. The angle between the top horizontal inner edge 139 and the top inclined inner edge 140 is approximately 18.5° to 30°, preferably approximately 24.5°. The front inner edges 137 to 140 may be curved.

[0161] Figure 52 Examples are shown along such Figure 50 A symmetrical cross-sectional view of the nasal cavity 127 along line XX. (See figure.) Figure 52 As shown, the generally planar triangular front bowtie-shaped inner surface 155 and the generally planar triangular rear bowtie-shaped inner surface 156 can be oriented with their vertices facing each other. The front bowtie-shaped inner surface 155 may slope downward as it extends from the rear center inner surface 153 in the lateral direction (e.g., directions +B and -B). The front bowtie-shaped inner surface 155 may slope towards the side inner surface 160 as it extends from the rear center inner surface 153 in the lateral directions +B and -B. For example, the front bowtie-shaped inner surface 155 may be oriented relative to the rear center inner surface 153 such that the angle between the two surfaces is 17.5° to 32.5°, preferably about 25°.

[0162] Figure 53 Examples are shown along such Figure 50 A cross-sectional view of the symmetrical nasal cavity 127 along the YY line. (See figure) Figure 53As illustrated, the rear bow tie-shaped inner surface 156 may slope downwards (e.g., in the D direction) as it extends from the rear center inner surface 153 in the lateral directions +B and -B. The angle of inclination between the rear bow tie-shaped inner surface 156 and the rear center inner surface 153 may differ from the angle of inclination between the front bow tie-shaped inner surface 155 and the rear center inner surface 153. More specifically, the angle of inclination between the rear bow tie-shaped inner surface 156 and the rear center inner surface 153 may be greater than the angle of inclination between the front bow tie-shaped inner surface 155 and the rear center inner surface 153. For example, the rear bow tie-shaped inner surface 156 may be oriented relative to the rear center inner surface 153 such that the angle between these surfaces is 30° to 45°, preferably about 37.5°.

The tooth tip assembly 10 may include: an adapter 12 configured to attach to a base edge, such as the base edge 108 of the tool 100. Figure 1 and Figure 2 The tooth tip assembly 10 may include a grounding tip 14 configured to attach to the adapter 12. The tooth tip assembly 10 may also include a retaining mechanism 500 for securing the grounding tip 14 to the adapter 12. The retaining mechanism 500 may be an exemplary embodiment of a retaining mechanism 13. The retaining mechanism 500 may include a retainer 525, a retainer block 530, and a spring 535. The adapter 12 may include a cutout 510 to allow mounting of the retainer block 530. The grounding tip 14 may include an opening 515 (such as a through-hole) to allow the retainer 525 to be mounted into the retainer block 530 when the grounding tip 14 is attached to the adapter 12. Once attached to the adapter 12, the grounding tip 14 may extend outward from a base edge (such as the base edge 108 of the tool 100) to make initial engagement with the work material.

Figure 56When the locking mechanism is engaged, the locking notch 545 can interact with the spring 535 to prevent the retainer 525 from being used with the bucket assembly 1 (see...).

[0165] Industrial applicability

[0166] The tooth tip assembly 10 according to this disclosure integrates several features that extend the service life of the tooth tip assembly 10. The design of the tooth tip assembly 10 according to this disclosure provides various surfaces and surface angles on the nose 26 and symmetrical nose 27 of the adapter 12, and corresponding surfaces and surface angles in the nose cavity 126 and symmetrical nose cavity 127 of the tooth tip 14. These surfaces and surface angles work together to provide various advantages, including increasing the contact area between the tooth tip 14 and the adapter 12, reducing stress on the adapter 12 and the tooth tip 14, increasing the friction between the tooth tip 14 and the adapter 12 during loading, increasing the stability of the tooth tip assembly 10 during loading, reducing the relative movement between the tooth tip 14 and the adapter 12, making the wear distribution of the tooth tip assembly 10 more uniform, reducing the load on the retaining mechanism 13, reducing the force required to remove the tooth tip 14 from the adapter 12, and reducing the volume of the nose 26 of the adapter 12 and increasing its strength. While the discussion below focuses primarily on the various surfaces and surface orientations of the nose 26 and the symmetrical nose 27, those skilled in the art will understand that when the tooth tip 14 is mounted on the adapter 12, the interaction of the relevant surfaces of the nose 26 and / or the symmetrical nose 27 with the corresponding surfaces in the nasal cavity 126 or the symmetrical nasal cavity 127 provides the described advantages.

[0167] The tooth tip assembly 10 according to this disclosure provides an increased contact area between the tooth tip 14 and the adapter 12. For example, when using the tooth tip assembly 10, it may bear loads in various directions. When a downward load is applied to the tooth tip assembly 10, a large portion of the load is borne by the front portion 48 of the top surface 46 of the nose 26 or the symmetrical nose 27 of the adapter 12. Because, as in Figure 10 As can be seen, the front portion 48 may include three different surfaces at different angles (anterior central surface 49 and two anterior inclined surfaces 50), so the total contact area between the front portion 48 and the corresponding anterior inner portion 148 of the nasal cavity 126 of the tooth tip 14 or the top inner surface 146 of the symmetrical nasal cavity 127 (as shown in the image) is... Figure 24 and Figure 32 (As can be seen in the image) is larger than the contact area when the front portion 48 and the corresponding front inner portion 148 are limited to a single surface. Similarly, with regard to the asymmetric adapter 12, due to the relative orientation of the rear rib portion 78, the rear rib side surface 82, and the shoulder surface 72 of the bottom surface 66 (as seen in the image), the contact area is greater than that of the front portion 48 and the corresponding front inner portion 148 when the contact area is limited to a single surface. Figure 11As can be seen from the image), these surfaces will also bear a large portion of the downward load, thus increasing the contact area with the corresponding surface of the inner bottom surface 166 of the nasal cavity 126 of the tooth tip 14 (as shown in the image). Figure 26 (As can be seen from the image) is greater than the contact area when the bottom surface 66 and the corresponding inner bottom surface 166 are composed of a single surface.

[0168] When an upward load is applied to the tooth tip assembly 10, a large portion of the load is borne by the rear portion 52 of the top surface 46 of the nose 26 or symmetrical nose 27 of the adapter 12, such as Figure 10 As shown. More specifically, the rear center surface 53 and the rear bowtie-shaped surface 56 will bear a large load. Since the rear center surface 53 and the rear bowtie-shaped surface 56 can be oriented at different angles, the total contact area with the corresponding surfaces of the nasal cavity 126 of the tooth tip 14 or the inner top surface 146 of the symmetrical nasal cavity 127 (e.g., Figure 24 and Figure 32 (As shown) is greater than the contact area when the top surface 46 and the corresponding top inner surface 146 are composed of a single surface.

[0169] When a lateral load is applied to the tooth tip assembly 10, the load is borne by the nose 26 or the symmetrical nose 27 having a lateral profile (such as...). Figure 8 Multiple surfaces (as shown) are distributed, including a front inclined surface 50, a front bowtie-shaped surface 55, a rear bowtie-shaped surface 56, a front surface 61 and a middle side surface 62, a rear side surface 63, and (in the case of the nose 26) a rib-side surface 80. Because these surfaces are oriented at different angles, the total contact area between the nose 26 or symmetrical nose 27 and the corresponding surfaces of the nasal cavity 126 or symmetrical nasal cavity 127 of the tooth cusp 14 (as shown) is... Figure 21 and Figure 29 (As shown) The contact area when the transverse contour of the nose 26 or the symmetrical nose 27 is composed of a single surface.

[0170] When a push-in load is applied to the tooth tip assembly 10, the load is generated by the nose 26 or the symmetrical nose 27 having Figure 9 or Figure 16 The contour in the front view is shared by multiple surfaces, such as the front surface 36, the rear center surface 53, the front bowtie surface 55, the rear side surface 63, and (in the case of the asymmetric adapter 12) the front rib portion 76, the rear rib portion 78, and the rib side surface 80. Because these surfaces are oriented at different angles, the total contact area between the nose portion 26 or the symmetrical nose portion 27 and the corresponding surfaces of the nasal cavity 126 or the symmetrical nasal cavity 127 of the tooth tip 14 (e.g., Figure 22 and Figure 30 (As shown) The contact area is greater than that of the front contour of the nose 26 or the symmetrical nose 27 when it is composed of a single surface.

[0171] Compared to the same load applied to the adapter 12 and tooth tip 14, which have a smaller contact area, the increased contact area between the nose 26 or symmetrical nose 27 of the adapter 12 and the nose cavity 126 or symmetrical nose cavity 127 of the tooth tip 14, as described above, reduces the stress on the adapter 12 and tooth tip 14.

[0172] The tooth tip assembly 10 according to this disclosure provides increased friction between the tooth tip 14 and the adapter 12 during loading. For example, when a downward load is applied to the tooth tip assembly 10, the tooth tip 14 mounted to the nose 26 will tend to slide forward, the top surface 46 of which slopes downward toward the front of the nose 26. However, in the tooth tip assembly 10 according to this disclosure, the front portion 48 and the rear bowtie-shaped surface 56 of the top surface 46 of the nose 26 of the adapter 12 have a reduced forward angle compared to the rear center surface 53 of the top surface 46, such as... Figure 8 and Figure 15 As shown. These reduced-angle surfaces increase the frictional force under downward loads that secures the tooth tip 14 to the appropriate position on the nose 26 or symmetrical nose 27 of the adapter 12.

[0173] When an upward load is applied to the tooth tip assembly 10, the tooth tip mounted to the nose 26 will tend to slide forward, with the bottom surface 66 of the nose inclined upward toward the front of the nose 26. However, in the tooth tip assembly 10 according to this disclosure, the front portion 68 of the bottom surface 66 (with respect to the nose 26) or the front central surface 49 of the top surface 46 (with respect to the symmetrical nose 27) may have a reduced forward angle compared to the rear portion 70 of the bottom surface 66 (with respect to the nose 26) or the rear central surface 53 of the top surface 46 (with respect to the symmetrical nose 27). For example, the front portion 68 or the front central surface 49 may be oriented substantially parallel to the substantially longitudinal axis "A", such as Figure 8 and Figure 15 As shown. This configuration increases the frictional force that secures the tooth tip 14 to the nose 26 of the adapter 12 at the appropriate position under upward load.

[0174] When a lateral load is applied to the tooth tip assembly 10, the load is borne by the nose 26 or the symmetrical nose 26 having a lateral profile (such as...). Figure 8 and Figure 15 Multiple surfaces (as shown) are distributed, including a sloping surface 50, a front bowtie-shaped surface 55, a rear bowtie-shaped surface 56, a front side surface 61 and a middle side surface 62, a rear side surface 63, and (in the case of the asymmetric adapter 12) a rib-side surface 80. Because these surfaces are oriented at different angles, the total contact area between the nose 26 or symmetrical nose 27 and the corresponding surfaces of the nasal cavity 126 or symmetrical nasal cavity 127 of the tooth tip 14 (as shown) is... Figure 21 and Figure 29(As shown) The contact area when the transverse contour of the nose 26 or the symmetrical nose 27 is composed of a single surface.

[0175] The tooth tip assembly 10 according to this disclosure provides increased stability to the tooth tip assembly 10 during loading. For example, when a downward load is applied to the tooth tip assembly 10, the front inclined surface 50 and the rear inclined surface 54 provided on both sides of the front center surface 49 and the rear center surface 53 (such as...) Figures 9 to 10 and Figures 16 to 17 The surfaces (as shown) combined with the corresponding surfaces of the nasal cavity 126 or the symmetrical nasal cavity 127 act as wedge-shaped surfaces, increasing the stability of the tooth tip assembly 10 under downward loads. Regarding the asymmetrical adapter 12, the rib-side surfaces 80 (as shown) provided on both sides of the bottom rib 74... Figure 9 and Figure 11 (As shown) Similarly, when a downward load is applied, the corresponding surface of the nasal cavity 126 acts as a wedge-shaped surface, thereby improving stability.

[0176] When an upward load is applied to the tooth tip assembly 10 with the asymmetric adapter 12, the front portion 68 of the bottom surface 66, combined with the corresponding surface of the nasal cavity 126, provides increased stability. This front portion may have a reduced forward angle compared to the rear portion 70 of the bottom surface 66. For example, the front portion 68 may be approximately parallel to the approximately longitudinal axis "A," as... Figure 8 As shown. Furthermore, regarding the nose portion 26 or the symmetrical nose portion 27, the rear collarbone-shaped surfaces 56 (as shown) are provided on both sides of the rear central surface 53. Figures 9 to 10 and Figures 16 to 17 The corresponding surface combination of the nasal cavity 126 (shown) and the symmetrical nasal cavity 127 also acts as a wedge surface when an upward load is applied to the tooth tip assembly, thereby improving stability.

[0177] When a lateral load is applied to the tooth tip assembly 10, the front inclined surface 50 of the nose 26 and the symmetrical nose 27, the front bowtie surface 55, the rear bowtie surface 56, and (in the case of the asymmetrical adapter 12) the rib side surface 80 (as shown in the figure) Figure 8 and Figure 15 The surfaces (shown) combine with the corresponding surfaces of the nasal cavity 126 or the symmetrical nasal cavity 127 to act as wedge-shaped surfaces, increasing stability by preventing the tooth tips 14 from pivoting around the front of the nose 26 or the symmetrical nose 27. Furthermore, compared to the nose 26 having a single flat side surface, the orientation differences between the anterior side surface 61 and the middle side surface 62 relative to the posterior side surface 63 (e.g., ...) Figure 10 and Figure 17 (As shown) it provides additional stability under lateral loads.

[0178] When a forward load is applied to the tooth tip assembly 10, the front inclined surface 50, the front bowtie surface 55, the rear bowtie surface 56, and the rear surface 63 of the nose 26 and the symmetrical nose 27, as well as (in the case of the asymmetrical adapter 12) the front rib portion 76, the rear rib portion 78, and the rib side surface 80 (these surfaces are oriented at different angles in the lateral direction, such as...) Figure 8 and Figure 15 (As shown) The corresponding surfaces of the tooth tip 14 are combined with the corresponding surfaces of the nasal cavity 126 or the symmetrical nasal cavity 127 to serve as wedge-shaped surfaces, thereby increasing the stability of the tooth tip 14 on the adapter 12.

[0179] The increased stability of the tooth tip 14 on the nose 26 or symmetrical nose 27 of the adapter 12, provided by the surfaces described above and their corresponding surfaces in the nose cavity 126 or symmetrical nose cavity 127 of the tooth tip 14, reduces the relative motion between the tooth tip 14 and the adapter 12 under each directional load. This reduction in relative motion provides the advantage of distributing overall wear throughout the tooth tip assembly 10, thereby increasing the durability of the tooth tip assembly 10. The reduction in relative motion also provides the advantage of reducing the load on the retaining mechanism 13, which is designed to secure the tooth tip 14 to the adapter 12. This reduction in load on the retaining mechanism 13 increases the reliability and durability of the retaining mechanism 13 and the entire tooth tip assembly 10.

[0180] The rear surface 63 also provides the benefit of reducing the force threshold required to remove the tooth tip 14 from the nose 26 or symmetrical nose 27 of the adapter 12. This is because, as Figure 10 and Figure 17 As shown, the rear surface 63 can be oriented such that the distance between the opposing surfaces increases as they extend rearward. Therefore, the rear surface 63 provides a release point during tooth tip removal and reduces the total force required to remove the tooth tip 14 from the adapter 12.

[0181] Additionally, for the asymmetric adapter 12, the bottom ribs 74 on the bottom surface 66 (as shown in the image) Figure 11 (as shown) and the corresponding bottom channel 174 of the nasal cavity 126 (as shown) Figure 22 (As shown) the tooth tip assembly 10 according to this disclosure provides a reduced volume of the nose 26 of the adapter 12 and enhanced strength.
