Description

Technical Field

[0001] This disclosure relates in general to earthmoving machinery with ground engagement implements, and more specifically, to ground engagement implements with a retaining mechanism having a threaded block locking mechanism. 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 they experience during earthmoving operations.

[0003] To facilitate earthmoving and extend implement life, multiple tip assemblies can be placed along the base edge of the implement and attached to its surface. The tip assemblies extend forward from the base edge as the first point of contact and penetration with the work material, reducing wear on the base edge. With this arrangement, the tip assemblies may suffer wear and breakage due to repeated engagement with the work material. Ultimately, the tip assemblies must be replaced, but the implement can remain usable after multiple tip assembly replacements. Depending on the various uses of the equipment and the work material, it may also be desirable to vary the type and / or shape of the tip assemblies to utilize the implement most effectively.

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

[0005] U.S. Patent No. 10,364,553 (“'553 Patent”) was published by Christopher D. Snyder on July 30, 2019, and discloses a ground engagement tool tip assembly including a base, a wear-resistant member, and a lock. The lock includes a retainer and a lock body. The lock body passes through alignment openings in the base, retainer, and wear-resistant member to engage the retainer and secure the wear-resistant member to the base. The lock body and retainer include corresponding fasteners having engaging elements such as lugs and threads.

[0006] The '553 patent could provide a ground engagement tool assembly comprising a base, a wear-resistant member, and a lock. However, the '553 patent requires the lock body to be held in place within the wear-resistant member by a nut or retaining ring. Providing the lock body and the nut or retaining ring may require precise manufacturing tolerances, which could potentially reduce the adequacy of the locking mechanism. Additionally, it may be difficult to ensure that the lock body is tightened to the appropriate degree to provide maximum support for the '553 patent's ground engagement tool tip assembly.

[0007] This disclosure aims to overcome one or more of the problems set forth above and other problems in the prior art. Summary of the Invention

[0049] Figure 1 An exemplary implement 100 for bottom-wear applications, such as loader applications, is illustrated. The implement 100 may take the form of a bucket assembly incorporating features of this disclosure. The bucket assembly may include... Figure 1 The bucket 102 is partially shown. The bucket 102 can be used for material excavation on a loader. The bucket assembly may include a pair of opposing arms 104, on which corresponding corner guards 106 may be mounted. The bucket 102 may include a plurality of tip assemblies 110. The bucket assembly may further include a plurality of edge protection assemblies 109 inserted between the tip assemblies 110, wherein the edge protection assemblies 109 and the tip assemblies 110 are fixed along a base edge 108 of the bucket 102.

[0050] Figure 2 Another exemplary implement 100 for top-wear applications, such as excavator applications, is illustrated. In this example, implement 100 may have the form of an excavator bucket assembly. The excavator bucket assembly may include a bucket 102 with corner guards 106 on both sides. The bucket 102 may include a plurality of tip assemblies 110. The excavator bucket assembly may further include an edge protection assembly 109 inserted between the tip assemblies 110, wherein the edge protection assembly 109 and the tip assemblies 110 are secured along a base edge 108 of the bucket 102.

[0051] Various embodiments of the tip component can be implemented in bottom-wear or top-wear applications. While specific tip component or component embodiments may be described with respect to specific bottom-wear or top-wear applications, it should be understood that the tip component is not limited to a particular type of application and can be interchanged between implements for various applications.

[0052] Figure 3 This is an exploded view illustrating the components of an exemplary tip assembly 110. The tip assembly 110 can be used to have a base edge (such as base edge 108 (see...)). Figures 1 to 2 The tool assembly 110 may include an adapter 205 and a ground engagement tip 210, the adapter being configured to attach to a base edge (such as base edge 108 of tool 100), the ground engagement tip being configured to attach to the adapter 205. The tip assembly 110 may further include a retaining mechanism 200 for securing the ground engagement tip 210 to the adapter 205. The retaining mechanism 200 may include a retainer 225, a retaining block 230, and a spring 235. The adapter 205 may include a cutout 220 to allow mounting of the retaining block 230. The ground engagement tip 210 may include an opening 215 (such as a through-hole) to allow the retainer 225 to be mounted into the retaining block 230 when the ground engagement tip 210 is attached to the adapter 205. Once attached to the adapter 205, the ground engagement tip 210 may extend outward from the base edge (such as base edge 108 of tool 100) for initial engagement with the work material.

[0053] Adapter 205 may extend from front end 206 to rear end 208 and may include top band 240 and bottom band 245. In one exemplary embodiment, as shown... Figure 3 As illustrated, the top belt 240 can be positioned higher than the bottom belt 245 relative to the direction of gravity. However, the terms top and bottom should be understood as defining positions relative to each other and not necessarily relative to the direction of gravity. For example, depending on the position of the tool 100 on the machine or its position when disassembled from the machine, the top belt 240 can be positioned higher or lower than the bottom belt 245 relative to the direction of gravity.

[0054] The top band 240 and the bottom band 245 may define a gap between them for accommodating the tool 100 (see...). Figures 1 to 2The adapter 205 is secured in place on the base edge 108. The top band 240 may have a bottom surface that can oppose and engage with the top surface of the base edge 108. The bottom band 245 may have a top surface that can oppose and engage with the bottom surface of the base edge 108. The adapter 205 can be secured in place on the base edge 108 by attaching the top band 240 and bottom band 245 to the base edge 108 using any known connection method or mechanism. In one embodiment, the top band 240, bottom band 245, and base edge 108 may have corresponding orifices through which fasteners such as bolts or rivets can be inserted to hold the adapter 205 in place. Alternatively, the top band 240 and bottom band 245 may be welded to the corresponding top and bottom surfaces of the base edge 108 such that the adapter 205 and the base edge 108 do not move relative to each other during use. The adapter 205 may also include a nose 250, which may have a longitudinal axis 251 that passes through the center of the nose 250 in a direction from the front end 206 to the rear end 208 of the adapter 205.

[0055] Figures 4 to 6 The adapter 205 is depicted (see Figure 3 Various views of the nose (250°). (e.g.) Figures 4 to 6 As depicted, the nose 250 of the adapter 205 may have a bottom surface 315, a top surface 330, opposing side surfaces 335, a front surface 340, and a rear edge 380. The rear edge 380 may be positioned substantially perpendicular to the longitudinal axis 251 (see [reference]). Figure 3 The plane of the adapter coincides with that of the adapter 205 at the location where the adapter 205 has its maximum cross-sectional area.

[0056] The bottom surface 315 may include a generally planar front portion 316 and a rear portion 317, the front portion being disposed adjacent to and extending rearward from the front surface 340, and the rear portion (e.g., in...) Figure 3 The tip 250 extends rearward from the front portion 316 toward the rear edge 380 in the direction from the front end 206 toward the rear end 208. The bottom surface 315 can provide a stable surface to serve as a contact area during loading, while reducing the tip assembly 110 (see...). Figure 3 Wear and tear.

[0057] The top surface 330 of the nose 250 can be configured in the machine tool 100 (see Figures 1 to 2 During use, support ground engagement tip 210 (see) Figure 3 And when bearing the load of the work material, it facilitates holding the ground engagement tip 210 on the nose 250. The top surface 330 may include multiple surfaces as explained below.

[0058] like Figure 5 As depicted, the nose 250 may include surfaces such as: a generally planar front surface 305 disposed adjacent to the front surface 340; a generally planar intermediate side surface 345 (e.g., in...) Figure 3 The front surface 305 extends rearward from the front end 206 toward the rear end 208; and the rear surface 350 extends rearward from the middle side surface 345 of the nose 250 to the rear edge 380.

[0059] The anterior surface 340 of the nose 250 can be flat, such as Figures 4 to 6 As shown. In other embodiments (not shown), the front surface may include a degree of curvature. For example... Figure 4 As depicted, the front surface 340 may be hexagonal in shape, including a bottom edge 341, opposing side edges 342 oriented at approximately 90° relative to the bottom edge 341, a top horizontal edge 343 oriented approximately parallel to the bottom edge 341, and an opposing top inclined edge 344 connecting the top horizontal edge 343 to the side edges 342. However, it is contemplated that the front surface may have a triangular, square, rectangular, circular, elliptical, polygonal, or any other shape.

[0060] like Figure 6 As depicted, the nose 250 may also include a bottom rib 320 on the bottom surface 315. The bottom rib 320 on the bottom surface 315 may include a generally planar front rib portion 321 and a generally planar rear rib portion 322, the front rib portion being inclined downward relative to the bottom surface 315, and the rear rib portion (e.g., in a direction from the top surface 330 toward the bottom surface 315) being inclined downward relative to the front rib portion 321, the front rib portion and the rear rib portion being located between opposing rib side surfaces. The bottom rib 320 improves stability during lateral loading and enhances wedging during push-in loading.

[0061] The side surface 335 of the nose portion 250 may be generally planar and extends between the bottom surface 315 and the top surface 330. For example... Figure 5 As depicted, the side surface 335 may include: a generally planar front side surface 331 disposed adjacent to the front surface 340; a generally planar middle side surface 332 extending rearward from the front side surface 331; and a rear side surface 333 extending rearward from the middle side surface 332 of the nose portion 250 to the rear edge 380.

[0062] Side surface 335 may include a cutout 220. Cutout 220 may be designed to accommodate retaining block 230 (see [reference]). Figure 19The cutout 220 may include a design to increase the contact surface area between the retaining block 230 and the nose 250. By increasing the contact surface area between the retaining block 230 and the nose 250, when the tip assembly 110 (see...) Figure 3 The load applied during use can be distributed throughout the tip assembly 110. This allows for a tight and stable connection between the adapter 205 and the ground engagement tip 210, which can reduce the load on the tip assembly 110 (see [link]). Figure 3 Wear and tear throughout its use. In some embodiments, each side surface 335 may have a cutout 220 for mounting the retaining mechanism 200. In other embodiments, only one side surface 335 may have a cutout 220 for mounting the retaining mechanism 200 (see [link to documentation]). Figure 3 ) cut 220.

[0063] like Figures 4 to 6 As shown, the notch 220 can be used in conjunction with the retaining mechanism 200 to retain the ground engagement tip 210 and the adapter 205 (see Figure 200). Figure 3 The connection between the cutout 220 and the retaining block 230 (see...) Figure 19 The complementary configuration allows the retaining block 230 to be mounted in a cutout 220 on one of the side surfaces of the side surface 335. The cutout 220 may include a cutout height CH, a cutout width CW, and a cutout depth CD, such as... Figure 5 and Figure 6 The incision width CW can be equal to the incision height CH, or up to twice the incision height CH. Additionally, the incision width CW can range between 10% and 50% of the nasal length NL. The incision depth CD can range between 10% and 100% of the posterior nasal width RNW.

[0064] The cutout 220 may include an outwardly inclined surface 390, an inner surface 391, an inner circular surface 392, and a base surface 393, such as Figure 4 and Figure 5 As depicted. Referring to the outwardly inclined surface 390, these surfaces may provide an inclined connection (such as a ramp) between the side surface 335 and the inner surface 391 of the cut 220. The outwardly inclined surface 390 may extend around the outer perimeter of the inner surface 391 of the cut 220. The outwardly inclined surface 390 may further include a partial or full rounded connection between the inner surface 391 and the side surface 335.

[0065] Cutout 220 may further include inner surface 391, such as Figure 4 As depicted. The inner surface 391 can be positioned at the cutout 220 and the retaining block 230 (see...). Figure 19The inner surface 391 can be located between the outer inclined surface 390 and the inner circular surface 392. The inner surface 391 can define the perimeter of the cut 220 into which the retaining block 230 can be inserted.

[0066] like Figure 7 The inner surface 391 is depicted (see...) Figure 4 The inner surface 391 may include a front surface 360, a front upper surface 362, an upper surface 364, a rear upper surface 366, a rear surface 368, a rear lower surface 370, a lower surface 372, and a front lower surface 374. The inner surface 391 may further include transition side surfaces 361, 363, 365, 367, 369, 371, 373, and 375.

[0067] like Figure 7 As depicted, the inner surface 391 may include the front surface 360. The front surface 360 ​​may interact with the retaining block 230 (see [link to documentation]). Figure 19 The contact surface 610 corresponds to the front surface 360. The front surface 360 ​​may extend between the transition side surface 361 and the transition side surface 375. The front surface 360 ​​may be planar and parallel to the front surface 340. Tip assembly 110 (see...) Figure 3 The tip assembly 110 may be subjected to peak load forces in directions toward and perpendicular to the front surface 340. Therefore, the front surface 360 ​​can have a relatively larger surface area than other side surfaces. This increased surface area allows the load applied to the tip assembly 110 to be distributed throughout the entire tip assembly 110, which can reduce wear on the tip assembly 110 during use. The front upper surface 362 can extend between the transition side surfaces 361 and 363. The front upper surface 362 can be parallel to the rear inclined surface 385. The upper surface 364 can extend between the transition side surfaces 363 and 365. The rear upper surface 366 can extend between the transition side surfaces 365 and 367.

[0068] The rear surface 368 may extend between the transition side surface 367 and the transition side surface 369. The rear surface 368 may be planar and parallel to the rear edge 380. Tip assembly 110 (see...) Figure 3 It may be subjected to large load forces in the directions toward the rear edge 380 and perpendicular to the rear surface 368. Cutout 220 (see...) Figure 4The lower rear surface 335 of the nose 250 can be located on the side surface 335 to provide a sufficiently large distance between the rear surface 368 and the rear edge 380 of the nose 250. Specifically, the distance between the rear surface 368 and the rear edge 380 of the nose 250 can exceed half the overall width of the cut 220 (measured from the front surface 360 ​​to the rear surface 368). By maximizing the surface area of ​​the side surface 335 between the rear surface 368 and the rear edge 380, the load applied in the direction toward the rear edge 380 can be distributed throughout the entire rear region of the nose 250. This distribution allows for a uniform load throughout the tip assembly 110 and can reduce wear on the tip assembly 110 during use. The lower rear surface 370 can extend between the transition side surface 369 and the transition side surface 371. The lower rear surface 372 can extend between the transition side surface 371 and the transition side surface 373. The lower front surface 374 can extend between the transition side surface 373 and the transition side surface 375.

[0069] like Figure 8 The inner surface 391 is depicted (see...) Figure 4 The front surface 360 ​​may further include transition side surfaces 361, 367, 369, and 375. The front surface 360 ​​can be connected to the front upper surface 362 via the transition side surface 361. Figure 8 As depicted, the transition side surface 361 allows the front surface 360 ​​and the front upper surface 362 to be connected relative to each other at an angle α. The angle α can range between 95˚ and 135˚. In an exemplary embodiment, as shown... Figure 8 As illustrated, angle α can be 110˚. The upper rear surface 366 can be connected to the rear surface 368 via a transition side surface 367. (See example...) Figure 8 As depicted, the transition side surface 367 allows the rear upper surface 366 and the rear surface 368 to be connected relative to each other at an angle δ. The angle δ can range between 120˚ and 150˚. In one exemplary embodiment, as shown... Figure 8 As illustrated, the angle δ can be 135˚. The rear surface 368 can be connected to the rear lower surface 370 via a transition side surface 369. (As shown...) Figure 8 As depicted, the transition side surface 369 allows the rear surface 368 and the rear lower surface 370 to be connected relative to each other at an angle ε. The angle ε can range between 120˚ and 150˚. In one exemplary embodiment, as shown... Figure 8 As illustrated, the angle ε can be 135˚. The lower front surface 374 can be connected to the front surface 360 ​​via the transition side surface 375. (As shown...) Figure 8 As depicted, the transition side surface 375 allows the lower front surface 374 and the front surface 360 ​​to be connected relative to each other at an angle θ. The angle θ can range between 95˚ and 135˚. In one exemplary embodiment, as shown... Figure 8As illustrated, angle θ can be 110˚. In some exemplary embodiments, angle α can be equal to angle θ, and angle δ can be equal to angle ε.

[0070] Cutout 220 may further include an inner circular surface 392, such as Figure 4 As depicted. The inner circular surface 392 can be positioned at the cutout 220 and the retaining block 230 (see...). Figure 19 Additional contact surface area is provided between the two components, thereby distributing the force throughout the tip assembly 110 (see [link]). Figure 3 In ), and reduce in machine 100 (see Figures 1 to 2 Wear of the tip component 110 during use. The inner circular surface 392 can be on the base surface 393 (see...) Figure 5 A transition is provided between the inner circular surface 392 and the inner surface 393. The inner circular surface 392 may define the inner circumference of the cutout 220 surrounding the base surface 393. Figure 9 As depicted, the inner circular surface 392 may include a front circular surface 460, a front upper circular surface 462, an upper circular surface 464, a rear upper circular surface 466, a rear circular surface 468, a rear lower circular surface 470, a lower circular surface 472, and a front lower circular surface 474. The inner circular surface 392 may further include transition circular surfaces 461, 463, 465, 467, 469, 471, 473, and 475.

[0071] The cut 220 may further include a base surface 393, such as Figure 5 The depicted base surface 393 may include a planar surface recessed within the cutout 220 for use with the retaining block 230 (see [reference]). Figure 19 The base surface 393 can provide additional contact surface area between the notch 220 and the retaining block 230 to distribute force throughout the tip assembly 110 (see...). Figure 3 The base surface 393 may be recessed into the side surface 335 of the nose portion 250 at a cut depth CD. The base surface 393 may be formed by an inner circular surface 392 (see...). Figure 4 The perimeter of the ) is limited.

[0072] Figure 10 An example is shown along line AA at 250 degrees along the nose (see...) Figure 9 Cross-sectional view of ). Figure 11 An example is shown along line BB of adapter 205 (see...). Figure 3 A cross-sectional view of the cut. The cut 220 may further include an upper draft angle UDA, a lower draft angle LDA, a rear draft angle RDA, and a front draft angle FDA, as shown below. Figure 10 and Figure 11The upper draft angle UDA and lower draft angle LDA, as depicted, can include angles ranging from 90˚ to 110˚. In one exemplary embodiment, as shown... Figure 10 As illustrated, the upper draft angle UDA and lower draft angle LDA can include angles of 91˚. The rear draft angle RDA and front draft angle FDA can include angles ranging from 90˚ to 110˚. In one exemplary embodiment, as Figure 11 As illustrated, the rear draft angle RDA and the front draft angle FDA can both comprise angles of 91˚. Although Figure 10 and Figure 11 The upper draft angle UDA, lower draft angle LDA, rear draft angle RDA, and front draft angle FDA are depicted, but the inner surface 391 (see...) Figure 4 Each inner surface in the ) may also include a similar draft angle.

[0073] Figure 12 A ground engagement tip 210 with an opening 215 is depicted, the opening being used to hold the retainer 225 (see...). Figure 15 Installed into retaining block 230 (see...) Figure 19 The ground engagement tip 210 may be generally wedge-shaped and have a rear edge 420. The tip may have a top outer surface 425 and a bottom outer surface 430, the top outer surface extending forward from the top of the rear edge 420 and the bottom outer surface extending forward from the bottom of the rear edge 420. The top outer surface 425 may slope downward relative to the rear edge 420 and the bottom outer surface 430 may slope upward, such that the top outer surface 425 and the bottom outer surface 430 converge at a front edge at the front portion of the ground engagement tip 210. The ground engagement tip 210 may also include lateral outer surfaces 435 extending on both sides of the ground engagement tip 210 between the top outer surface 425 and the bottom outer surface 430.

[0074] like Figure 12 As depicted, the lateral outer surface 435 of the ground engagement tip 210 may include an opening 215 for mounting the ground engagement tip 210 to the adapter 205 (see [link]). Figure 3 When the upper part is used to accommodate the retainer 225 (see above) Figure 15 The opening 215 may be a through-hole extending through the lateral outer surface 435 of the ground engagement tip 210. The ground engagement tip 210 may include openings 215 on both sides, such as... Figure 12As depicted. In other embodiments, the ground engagement tip 210 may include an opening 215 on its right-side outward surface 435 or left-side outward surface 435. The opening 215 may include an opening depth OD and a diameter D. The opening depth OD may be the same as the ground engagement tip thickness T or up to three times the depth of the ground engagement tip thickness T. In one exemplary embodiment, as Figure 12 As depicted, the opening depth OD can be twice the depth of the ground joint tip thickness T. The diameter D of the opening 215 can range from 40% to 100% of the height H, such as... Figure 13 As depicted. In one exemplary embodiment, as Figure 12 and Figure 13 As depicted, the diameter D of the opening 215 can be 60% of the height H.

[0075] like Figure 13 As depicted, the ground engagement tip 210 can be configured to be received in the nose 250 (see...). Figure 4 The nasal cavity 440 may be defined within the ground engagement tip 210. The nasal cavity 440 may have a configuration complementary to the configuration that accommodates the nose 250, and may include a bottom inner surface 445, a top inner surface 447, a pair of opposing side inner surfaces 449, and an anterior inner surface 450.

[0076] like Figure 14 As depicted, the lateral outer surface 435 of the ground engagement tip 210 may include an opening 215 for mounting the ground engagement tip 210 to the adapter 205 (see [link]). Figure 3 When the upper part is used to accommodate the retainer 225 (see above) Figure 15 The opening 215 can be pre-positioned so that the retainer 225 can be mounted to the retaining block 230 through the opening 215 (see...). Figure 19 When the retainer 225 is in contact with the opening 215, good contact is provided. This is achieved by increasing the contact surface area between the retainer 225 and the opening 215, which is applied to the tip assembly 110 (see [link]). Figure 3 The load can be distributed between the retainer 225 and the opening 215 of the ground engagement tip 210. The opening 215 may also include a draft surface region 405 around the circumference of the opening 215. The draft surface region 405 can reduce surface contact during the removal of the retainer 225 from the retainer block 230.

[0077] Figures 15 to 18 A retainer 225 is depicted for retaining the retaining mechanism 200, which is used to hold the ground engagement tip 210 and the adapter 205 (see [link]). Figure 3 The connection between ). Figure 16 An example is shown for retainer 225 along line CC (see Figure 15A cross-sectional view of the retainer 225. The retainer 225 may include an outer diameter OD, a thread diameter TD, a block diameter BD, and a locking width DW, such as... Figure 16 As depicted. In some embodiments, the thread diameter TD can be at least 90% of the outer diameter OD, but not exceeding the length of the outer diameter OD. In some exemplary embodiments, such as Figure 16 As depicted, the outer diameter OD of the retainer 225 can be equal to the thread diameter TD of the retainer 225. In some exemplary embodiments, the block diameter BD can be between 50% and 90% of the outer diameter OD. In one exemplary embodiment, as... Figure 16 As depicted, the block diameter BD can be 75% of the outer diameter OD. In some exemplary embodiments, the slot width DW can range between 50% and 90% of the block diameter BD. In one exemplary embodiment, as... Figure 16 As depicted, the slot width DW can be 80% of the block diameter BD.

[0078] The retainer 225 may further include a cavity 505, a thread 510, a locking notch 515, and a chamfered bottom surface 520. For example... Figure 17 As depicted, retainer 225 may include cavity 505. Cavity 505 may allow the use of a tool to rotate retainer 225, including but not limited to a flathead screwdriver, square-head actuator, pry bar, or any other tool suitable for rotating retainer 225. The size and shape of cavity 505 may be designed to accommodate such a tool, such that retainer 225 can be rotated to retainer block 230 (see [link to image]). Figure 19 The square shape of the cavity 505 improves the ease with which the end user can remove the retainer 225 from the retaining block 230. For example, in the tip assembly 110 (see...) Figure 3 During use, dust and debris may become trapped in the retaining mechanism 200. Because the cavity 505 is square, an impact hammer tool can be used to remove the dust and debris trapped in the retaining mechanism 200 and connect to the square cavity 505 to remove the retainer 225 from the retaining block 230. This improves the safety of the end user when disassembling the tip assembly 110, because even if dust and debris may be trapped in the retaining mechanism 200, the end user does not need specific tools to remove the retainer 225 from the retaining block 230.

[0079] The retainer 225 may further include a thread 510. The size and pitch of the thread 510 may be designed such that the thread 510 can rotate to the retainer 230 (see [link]). Figure 21In the internal thread 625 of the retainer 225. For example, thread 510 may include a thread wrap angle TWA, which may represent the angle between radial lines connecting the ends of thread 510 in a plane substantially perpendicular to the longitudinal axis of retainer 225. In some embodiments, thread wrap angle TWA may include a wrap angle ranging from 90˚ to 540˚. In an exemplary embodiment, as Figure 18 As depicted, the thread wrap angle (TWA) can include a 360˚ wrap angle. When the retainer 225 is mounted in the retainer block 230, the thread 510 can interact with the internal thread 625 of the retainer block 230 to prevent linear movement of the retainer 225 within the retainer block 230. Additionally, because the thread 510 can have a thread wrap angle (TWA) between 90˚ and 540˚, the retainer 225 can be removed from the retainer block 230 more easily. For example, dust and debris may become trapped between the internal thread 625 of the retainer block 230 and the thread 510 of the retainer 225, which could result in increased friction when the retainer 225 is removed from the retainer block 230. Using a thread 510 with a thread wrap angle (TWA) between 90˚ and 540˚ reduces the amount of dust and debris that may enter the retainer block 230, thereby reducing the friction caused by such dust and debris when the retainer 225 is removed from the retainer block 230.

[0080] The retainer 225 may further include a locking notch 515. For example... Figure 16 As depicted, retainer 225 may include two locking notches 515 positioned on opposite sides of retainer 225, below thread 510 and above chamfered bottom surface 520. The locking notches 515 may include notches in the body of retainer 225, the size and shape of which may be designed to allow spring 235 (see [reference]) to pass through. Figure 23 The spacer retracts into the locking notch 515. For example, in some embodiments, the locking gap DG can range between 0.5 mm and 25 mm. In an exemplary embodiment, as shown... Figure 16 As depicted, the locking gap DG can be 2mm. The locking notch 515 can interact with the spring 235 to prevent the retainer 225 from being in the tool 100 (see...). Figures 1 to 2 Rotation during use. If the retainer 225 begins to move and deviate from alignment due to overload, the interaction between the locking notch 515 and the spring 235 can also provide stability for the retainer 225.

[0081] The locking notch 515 may include a lower surface 530 and an inclined upper surface 525, such as Figure 16 As depicted. The lower surface 530 can be made accessible by spring 235 (see...) Figure 23 The retainer 225 is deflected to unlock from its locked position, thus preventing the retainer 225 from disengaging from the retainer block 230 (see [link]). Figure 19 The lower surface 530 may include a capture angle CA. The capture angle CA may include an angle ranging from 90˚ to 135˚. In one exemplary embodiment, as... Figure 16 As depicted, the capture angle CA can include an angle of 90˚. In the tip assembly 110 (see...) Figure 3 During use, the retainer 225 may be subjected to forces that push it into the retainer block 230. The inclined upper surface 525 can provide a gap between the retainer 225 and the top edge of the spring 235, allowing the retainer 225 to move further into the retainer block 230 without generating greater stress on either the retainer 225 or the retainer block 230. The inclined upper surface 525 may include a stability angle SA. The stability angle SA may include an angle ranging from 90˚ to 135˚. In one exemplary embodiment, as... Figure 16 The stability angle SA can be described as an angle of 124˚.

[0082] like Figure 18 As depicted, retainer 225 may also include a chamfered bottom surface 520. The chamfered bottom surface 520 may be angled inwards as it extends downwards. The chamfered bottom surface 520 may facilitate mounting retainer 225 onto retainer block 230 (see [link to image]). Figure 19 For example, when the retainer 225 rotates into the retainer block 230, the chamfered bottom surface 520 can allow the spring 235 (see) to be inserted. Figure 23 ( ) Deflection. After the retainer 225 has rotated to the proper position in the retainer block 230, the spring 235 can engage the locking notch 515 of the retainer 225 to prevent the retainer 225 from rotating further.

[0083] Figures 19 to 22 An example is shown of a retaining block 230 for retaining mechanism 200, which is used to retain ground engagement tip 210 and adapter 205 (see [link]). Figure 3 The connection between ) . For example Figure 19 As depicted, the retaining block 230 may have a cavity 232 configured to receive the retainer 225, as further explained below. The retaining block 230 may also have an outer surface 234. The outer surface 234 may define a contact surface 610 on one side of the retaining block 230, a back surface 612 on the opposite side of the retaining block 203, and an inclined surface 615 located between the contact surface 610 and the back surface 612. The contact surface 610 may be flat and may increase the distance between the retaining block 230 and the nose 250 (see...). Figure 4 The increased contact surface area between the side surfaces 335 of the retaining block 230 and the nose 250 allows the load to be distributed across the entire tip assembly 110 (see [link]). Figure 3This reduces wear on both retaining block 230 and adapter 205.

[0084] The outer surface of retaining block 230 may further include an inclined surface 615 angled relative to contact surface 610. The inclined surface 615 of retaining block 230 can distribute multi-directional load forces throughout adapter 205 (see...). Figure 3 The size, angle, and length of the inclined surface 615 can be designed to maximize the available surface area on the side surface 335 of the adapter 205. For example, the inclined surface 615 can be connected with the cutout 220 (see...). Figure 4 The inner surface 391 and inner circular surface 392 correspond to each other. Increasing the contact surface area between the inclined surface 615 and the notch 220 can distribute the load force throughout the tip assembly 110, which can reduce the stress on the retaining block 230, adapter 205 and ground engagement tip 210 (see See Figure 3 Wear and tear.

[0085] like Figure 19 As depicted, retaining block 230 may include a draft cylindrical surface region 605. The draft cylindrical surface region 605 can reduce the distance between retaining block 230 and retainer 225 (see [link to image]). Figure 15 The reduced contact surface area due to the draft cylindrical surface area 605 can facilitate the removal of the retainer 225 from the retainer block 230.

[0086] like Figure 22 As depicted, the outer surface of the retaining block 230 may further include a back surface 612 opposite to the contact surface 610. A slot 620 may extend through the back surface 612 for inserting the spring 235 (see [link to original text]). Figure 23 Therefore, slot 620 can be located on the surface of retaining block 230 opposite to contact surface 610. The height and width of slot 620 can be designed to allow spring 235 to be mounted therein. For example, the height of slot 620 can be greater than the cross-sectional thickness XT of spring 235. The width of slot 620 can be greater than the width of front portion 705.

[0087] Figure 21 Example of holding block 230 along such Figure 19 The cross-sectional view of line DD is shown. (As shown) Figure 21 As depicted, retaining block 230 may include internal threads 625 located within cavity 232. The internal threads 625 of retaining block 230 may engage with retainer 225 (see [reference]). Figure 15The thread 510 of the retainer 225 corresponds to the thread 510 of the retainer 225. During installation, the retainer 225 can be rotated into the retainer 230, and the internal thread 625 of the retainer 230 can engage with the thread 510 of the retainer 225. The internal thread 625 prevents the retainer 225 from linearly moving out of or into the retainer 230 during operation. Additionally, using a single internal thread 625 minimizes the risk of damage to the tip assembly 110 (see [link]). Figure 3 The amount of dust and debris that may enter the retaining block 230 during use. Minimizing dust and debris between the internal thread 625 and the thread 510 can reduce the frictional forces generated when the end user removes the retainer 225 from the retaining block 230.

[0088] like Figure 22 As depicted, retaining block 230 may include a cutout 630 within its body. Cutout 630 may be coplanar with slot 620. Cutout 630 may provide space within retaining block 230 to allow for the retention of retainer 225 (see...) Figure 15 When installed in retaining block 230, spring 235 (see...) Figure 23 Deflection. When the retainer 225 is installed into the retainer block 230, the spring 235 can deflect from its rest position into the cutout 630, and after the retainer 225 is installed into the retainer block 230, the spring 235 can retract from the cutout 630 and engage with the locking cutout 515 of the retainer 225.

[0089] like Figure 22 As further described, the retaining block 230 may include a block diameter BD and a block width BW. The block diameter BD may range between 30% and 90% of the block width BW. In one exemplary embodiment, as... Figure 22 As depicted, the block diameter BD can be 60% of the block width BW.

[0090] Figure 23 An exemplary embodiment of spring 235 is illustrated. Spring 235 can pass through slot 620 (see...) Figure 20 The retainer 225 is installed within the retaining block 230. When the retainer 225 is installed within the retaining block 230, the spring 235 can interact with the retainer 225 (see [link]). Figure 15 The retaining notch 515 interacts with the spring 235. This interaction between the spring 235 and the retainer 225 prevents the retainer 225 from engaging with the tip assembly 110 (see...). Figure 3The spring 235 may include a front portion 705, a rear portion 710, and a side portion 715. The front portion 705 may be narrower than the rear portion 710. The narrower front portion 705 may facilitate mounting the spring 235 into the retaining block 230 through the slot 620. When the spring 235 is mounted into the retaining block 230, the larger rear portion 710 may snap into place, which may prevent the spring 235 from dislodging from the retaining block 230 through the slot 620. The spring 235 may further include a side portion 715. The side portion 715 may interact with the locking notch 515 of the retainer 225 to prevent the retainer 225 from rotating during operation of the tip assembly 110. The cross-sectional shape of the spring 235 may be square, rectangular, circular, or elliptical, or may have any other shape.

[0091] Spring 235 may include spring length SL, spring width SW, cross-sectional width XW, cross-sectional thickness XT, front length FL, and rear length RL, such as Figure 24 and Figure 25 As depicted. The spring length SL can be a length ranging from the spring width SW to four times the spring width SW. In one exemplary embodiment, as... Figure 24 As depicted, the spring length SL can be 1.5 times the spring width SW. The cross-sectional width XW can range between 0.5 mm and 12 mm. In one exemplary embodiment, as... Figure 24 As depicted, the cross-sectional width XW can be 1.5 mm. The cross-sectional thickness XT can range between 0.5 mm and 12 mm. In an exemplary embodiment, as... Figure 25 As depicted, the cross-sectional thickness XT can be 1.5 mm. The front length FL of the spring 235 can be equal to the rear length RL, and not exceed twice the length of the rear length RL. In an exemplary embodiment, as... Figure 24 As depicted, the front length FL can be equal to the rear length RL.

[0092] like Figures 26 to 29 The shapes of the depicted front portion 705 or rear portion 710 can include various shapes. For example... Figures 26 to 29 The front portion 705, as depicted, can be flat, circular, concave, or convex. The shapes of the front portion 705 and the rear portion 710 of the spring 235 can be determined based on a desired flexibility-to-stiffness ratio or manufacturing flexibility. Although Figures 26 to 29 The front portion 705 can be depicted as flat, round, concave, or convex, but the rear portion 710 can also be flat, round, concave, or convex. For example... Figures 26 to 29Any combination of the shapes of the front portion 705 and the rear portion 710 depicted can be used to provide the desired level of flexibility for the spring 235.

[0093] Figure 30 The retaining block 230 and retainer 225, which are installed in the adapter 205 and the ground engagement tip 210, are depicted along the... Figure 36 The cross-sectional view of the line EE depicted. (See diagram below.) Figure 30 As shown, retaining block 230 is mounted within cutout 220 of adapter 205. Ground engagement tip 210 is mounted above nose 250 of adapter 205, and retainer 225 is mounted into retaining block 230 through opening 215 of ground engagement tip 210. Spring 235 can interlock with locking cutout 515 of retainer 225. This interconnection between spring 235 and locking cutout 515 prevents the use of tip assembly 110 (see...) Figure 3 When the retainer 225 rotates within the retainer block 230.

[0094] Figure 31 The retaining block 230 and retainer 225, which are installed in the adapter 205 and the ground engagement tip 210, are depicted along the... Figure 36 The cross-sectional view taken from the line FF depicted. For example... Figure 31 As shown, retaining block 230 is mounted within cutout 220 of adapter 205. Ground engagement tip 210 is mounted above nose 250 of adapter 205, and retainer 225 is mounted into retaining block 230 through opening 215 of ground engagement tip 210. Thread 510 can interact with internal thread 625 to prevent damage when using tip assembly 110 (see...). Figure 3 When the retainer 225 moves linearly within the retainer block 230, the retainer 225 may also move linearly. Additionally, as shown... Figure 31 As shown, the opening 215 of the ground engagement tip 210 can be pre-positioned to provide maximum contact between the retainer 225 and the opening 215. This contact prevents the retainer 225 from moving within the retaining block 230 when the tip assembly 110 is used.

[0095] Figure 32 A front view of a retainer 225 is depicted, which is mounted within an opening 215 of a ground engagement tip 210. The inner diameter of the opening 215 may correspond to the outer diameter of the retainer 225, allowing the retainer 225 to be mounted within the opening 215 while maintaining surface contact between the retainer 225 and the opening 215.

[0096] Figure 33 A three-dimensional rendering depicts a retainer 225 mounted within a retaining block 230 via an opening 215 at the ground engagement tip 210. (See attached image.) Figure 33 As depicted, when using the tip component 110 (see...) Figure 3When the ground engagement tip 210 is engaged, the retainer 225 can be recessed in the opening 215 of the ground engagement tip 210 to protect the retainer 225 from external forces.

[0097] Industrial applicability

[0098] Figures 34 to 36 A method for assembling the tip assembly 110 is depicted. Spring 235 (see...) Figure 23 ) can be passed through slot 620 (see Figure 20 It is installed inside retaining block 230. (For example...) Figure 34 As shown, the retaining block 230 with spring 235 can be inserted into the cutout 220 of adapter 205. Figure 34 and Figure 35 As shown, after the retaining block 230 is installed in the cutout 220 of the adapter 205, the ground engagement tip 210 can be installed above the nose 250 of the adapter 205. The ground engagement tip may include a nose cavity 440 (see...). Figure 13 The size and shape of the nasal cavity are complementary to those of the nose 250, allowing the nose 250 of the adapter 205 to be placed within the nasal cavity 440 of the ground engagement tip 210. Figure 36 As shown, the retainer 225 can be mounted within the retainer block 230 through the opening 215 of the ground engagement tip 210. The retainer 225 can be rotated to engage the thread 510 of the retainer 225 (see...). Figure 15 It can be used with the internal thread 625 of retaining block 230 (see...) Figure 21 The retainer 225 is interconnected and mounted within the retaining block 230. When the retainer 225 is mounted within the retaining block 230, the chamfered bottom surface 520 of the retainer 225 allows the spring 235 to deflect to the cutout 630 of the retaining block 230 (see...). Figure 22 Once the retainer 225 is fully installed within the retainer block 230, the spring 235 can engage with the locking notch 515 of the retainer 225. After the retainer 225 is locked within the retainer block 230, the retaining mechanism 200 (see [link to retaining mechanism])... Figure 3 ) can be used in machine 100 (see Figures 1 to 2 During use, the connection between the adapter 205 and the ground engagement tip 210 is maintained.

[0099] The advanced component 110 can be reverse-engineered as follows: Figures 34 to 36 Disassemble using the steps shown. Figure 36 A tip assembly 110 in its assembled form is depicted, wherein a retainer 225 is mounted within a retaining block 230 through an opening 215 in the ground engagement tip 210. The retainer 225 can be removed from the retaining block 230 through the opening 215 in the ground engagement tip 210, as... Figure 35As depicted. Retainer 225 can be removed by rotating it out of retainer block 230 using a tool, including but not limited to a flathead screwdriver, square-head drive, pry bar, or any other tool suitable for rotating retainer 225. Such a tool can be used with respect to the cavity 505 of retainer 225 (see...). Figure 17 The ground engagement tip 210 can then be removed from the nose 250 of the adapter 205, as follows: Figure 34 shown.

[0100] Figures 37 to 40 The image depicts the situation when the retainer 225 is mounted on the retainer block 230 (see [reference]). Figure 19 The deflection mode of spring 235 in the middle. Figure 37 The retainer 225 is depicted in the 180˚ position, where the 0˚ position indicates that the retainer 225 is in its locked position. In the 180˚ position, the spring 235 can be in its natural rest position when the chamfered bottom surface 520 begins to interact with the spring 235. As the retainer 225 rotates into the retaining block 230, the chamfered bottom surface 520 can begin to deflect the spring 235. Figure 38 The retainer 225 is depicted in a 70° position. (As shown) Figure 38 As depicted, when the bottom chamfered surface 520 has rotated beyond the spring 235, the spring 235 can be in a deflected position. The spring 235 can then begin to interact with the edge of the locking notch 515. Figure 39 The retainer 225 is depicted in a 25° position. (As shown) Figure 39 As depicted, as the retainer 225 continues to rotate, the spring 235 can be in a deflected position, thereby increasing the contact between the spring 235 and the locking notch 515. Figure 40 The retainer 225 is depicted in the 0° locked position. In this position, the retainer 225 is fully mounted within the retainer block 230, and the spring 235 is fully engaged with the locking notch 515. Figure 40 As depicted, spring 235 can no longer deflect and can be locked within the locking notch 515. When as Figure 40 When depicted in the locked position, the locking notch 515 can interact with the spring 235 to prevent the retainer 225 from being in the machine tool 100 (see...). Figures 1 to 2 Rotate during use. If retainer 225 begins to move and deviate from alignment due to overload, then Figure 40 The locking position also provides stability for retainer 225.

[0101] Figures 41 to 46 The image depicts the retaining mechanism 200 moving along the retaining block 230 when the retainer 225 is installed in the retaining block 230. Figure 36 An exemplary cross-sectional view of the line EE depicted. Figure 41 The retainer 225 is depicted in the 450˚ position, where the 0˚ position represents the locked position, in which the retainer 225 is fully mounted in the retainer block 230. (See image) Figure 41 As depicted, when the thread 510 of the retainer 225 begins to interact with the internal thread 625 of the retainer 230, the retainer 225 can be partially mounted within the retainer 230. The spring 235 can be in a natural rest position within the retainer 230. Figure 42 The retainer 225 is depicted in a 270° position. In this 270° position, the retainer 225 can be further rotated into the retainer block 230, thereby increasing the contact between the thread 510 of the retainer 225 and the internal thread 625 of the retainer block 230. Figure 43 The retainer 225 is depicted in a 180° position. In this 180° position, the retainer 225 can be further rotated into the retainer block 230. The chamfered bottom surface 520 can begin to contact the spring 235. As the retainer 225 rotates into the retainer block 230, the chamfered bottom surface 520 can help deflect the spring 235. Figure 44 The retainer 225 is depicted in a 70° position. In this 70° position, the spring 235 can be deflected into the cutout 630 of the retainer block 230. As the retainer 225 rotates further into the retainer block 230, the retainer can deflect the spring 235 into the cutout 630 of the retainer block 230. Figure 45 A retainer is depicted in a 25° position. In this 25° position, spring 235 can be deflected by retainer 225 into cutout 630 of retainer block 230. As retainer 225 rotates further into retainer block 230, spring 235 can begin to interact with locking cutout 515 of retainer 225. Figure 46 The retainer 225 is depicted in the 0° locked position. In this position, the retainer 225 can be mounted within the retaining block 230, and the spring 235 can engage within the locking notch 515. The internal thread 625 of the retaining block 230 can fully interconnect with the thread 510 of the retainer 225 to prevent linear movement of the retainer 225 within the retaining block 230. Figure 46 As depicted, spring 235 can no longer deflect and can be locked within the locking notch 515. When as Figure 46 When depicted in the locked position, the locking notch 515 can interact with the spring 235 to prevent the retainer 225 from being in the machine tool 100 (see...). Figures 1 to 2 Rotate during use. If retainer 225 is affected by tip assembly 110 (see...) Figure 3 If the overload causes it to start moving and deviate from alignment, then Figure 46 The locking position also provides stability for retainer 225.

[0102] Figures 47 to 52 A three-dimensional rendering of the retaining mechanism 200 is shown when the retainer 225 is installed inside the retaining block 230. Figure 47 The retainer 225 is depicted in the 450˚ position, where the 0˚ position represents the locked position, in which the retainer 225 is fully mounted in the retainer block 230. (See image) Figure 47 As depicted, when the thread 510 of the retainer 225 begins to interact with the internal thread 625 of the retainer 230, the retainer 225 can be partially mounted within the retainer 230. The spring 235 can be in a natural rest position within the retainer 230. Figure 48 The retainer 225 is depicted in a 270° position. In this 270° position, the retainer 225 can be further rotated into the retainer block 230, thereby increasing the contact between the thread 510 of the retainer 225 and the internal thread 625 of the retainer block 230. Figure 49 The retainer 225 is depicted in a 180° position. In this 180° position, the retainer 225 can be further rotated into the retainer block 230. The chamfered bottom surface 520 can begin to contact the spring 235. As the retainer 225 rotates into the retainer block 230, the chamfered bottom surface 520 allows the retainer 225 to deflect the spring 235. Figure 50 The retainer 225 is depicted in a 70° position. In this 70° position, the spring 235 can be deflected into the cutout 630 of the retainer block 230. As the retainer 225 rotates further into the retainer block 230, the retainer can deflect the spring 235 into the cutout 630 of the retainer block 230. Figure 51 A retainer is depicted in a 25° position. In this 25° position, spring 235 can be deflected by retainer 225 into cutout 630 of retainer block 230. As retainer 225 rotates further into retainer block 230, spring 235 can begin to interact with locking cutout 515 of retainer 225. Figure 52 The retainer 225 is depicted in the 0° locked position. In this position, the retainer 225 can be mounted within the retaining block 230, and the spring 235 can engage within the locking notch 515. Figure 52 As depicted, spring 235 can no longer deflect and can be locked within the locking notch 515. When as Figure 52 When depicted in the locked position, the locking notch 515 can interact with the spring 235 to prevent the retainer 225 from being in the machine tool 100 (see...). Figures 1 to 2 Rotate during use. If retainer 225 is affected by tip assembly 110 (see...) Figure 3 If the overload causes it to start moving and deviate from alignment, then Figure 52 The locking position also provides stability for retainer 225.

[0103] Figures 53 to 58 The diagram depicts the retaining mechanism 200 moving along the retaining block 230 when the retaining member 225 is installed in the retaining block 230. Figures 47 to 52 The cross-sectional view of the line GG depicted. Figure 53 The retainer 225 is depicted in the 450˚ position, where the 0˚ position represents the locked position, in which the retainer 225 is fully mounted in the retainer block 230. (See image) Figure 53 As depicted, the spring 235 can be in a natural resting position within the retaining block 230. Figure 54 The retainer 225 is depicted in a 270° position. In this 270° position, the retainer 225 can be further rotated into the retaining block 230, and the spring 235 can be in a natural rest position within the retaining block 230. Figure 55 The retainer 225 is depicted in a 180° position. In this 180° position, the chamfered bottom surface 520 of the retainer 225 can begin to contact the spring 235. As the retainer 225 rotates into the retainer block 230, the chamfered bottom surface 520 allows the retainer 225 to deflect the spring 235. Figure 56 The retainer 225 is depicted in a 70° position. In this 70° position, the spring 235 can be deflected into the cutout 630 of the retainer block 230. As the retainer 225 rotates further into the retainer block 230, the retainer can deflect the spring 235 into the cutout 630 of the retainer block 230. Figure 57 A retainer is depicted in a 25° position. In this 25° position, spring 235 can be deflected by retainer 225 into cutout 630 of retainer block 230. As retainer 225 rotates further into retainer block 230, spring 235 can begin to interact with locking cutout 515 of retainer 225. Figure 58 The retainer 225 is depicted in the 0° locked position. In this position, the retainer 225 can be mounted within the retaining block 230, and the spring 235 can engage within the locking notch 515. Figure 58 As depicted, spring 235 can no longer deflect and can be locked within the locking notch 515. When as Figure 58 When depicted in the locked position, the locking notch 515 can interact with the spring 235 to prevent the retainer 225 from being in the machine tool 100 (see...). Figures 1 to 2 Rotate during use. If retainer 225 is affected by tip assembly 110 (see...) Figure 3 If the overload causes it to start moving and deviate from alignment, then Figure 58 The locking position also provides stability for retainer 225.
