Description

Technical Field

[0001] The present invention relates to a treibglied for a saw chain and an arrangement structure for multiple treibglieds for a saw chain. Background Technology

[0002] A saw chain, mounted on a workpiece (such as a motor saw), is used to remove or cut workpieces. A saw chain can consist of numerous links, such as drive links, cutting links, and connecting links.

[0003] The drive link has a drive protrusion (Treibansatz) on its lower side, which engages with a groove in the guide rail when the saw chain is mounted. A drive link ridge (Treibgliedhöcker) may be provided on the upper side of the drive link. This type of drive link is also called a ridged drive link. In the saw chain's travel direction, the drive link with the ridge is positioned in front of the cutting link and serves to reinforce the depth limiter of the cutting link. As a result, the saw chain has a particularly low backlash.

[0004] This transmission element is manufactured using a stamping method. A sheet metal strip is guided through a stamping tool, wherein the upper and lower parts continuously close and open, and the transmission element is punched out from the sheet metal strip.

[0005] A disadvantage of known transmission links is that, due to their relatively large area size, only a low output can be obtained for each strip during the manufacturing process. Summary of the Invention

[0006] The purpose of this invention is to provide a transmission element of this type that enables cost-effective manufacturing of both the transmission element and the saw chain.

[0007] This objective is achieved through a drive link for a saw chain, wherein the drive link has two openings for hinge elements, a drive protrusion, and a drive link ridge; wherein the drive link is planarly constructed and extends in a drive link plane; wherein the drive link has an opening plane that includes the central axis of the opening and extends perpendicular to the drive link plane; wherein the drive link has a transverse plane that is perpendicular to the opening plane and extends centrally between the central axes of the two openings; and wherein the drive link has a longitudinal axis that extends in the drive link plane and intersects with the openings. The central axes intersect, wherein the transmission link protrusion is constructed asymmetrically about the transverse plane, wherein the transmission link has an upper side away from the opening plane, the upper side extending at least partially at the transmission link protrusion, wherein a functional surface and a contact surface spaced apart from the functional surface are provided on the upper side of the transmission link, and wherein the functional surface is constructed on the transmission link protrusion and includes an upper section in which the upper side has a maximum distance (a) from the opening plane, wherein the functional surface on the upper side of the transmission link is constructed symmetrically about the symmetrical point with respect to the contact surface in the direction of view toward the transmission link plane.

[0008] In stamping methods, as in other manufacturing methods, the goal is always, in principle, to obtain a workpiece profile that corresponds to the theoretical profile to be manufactured. To achieve this, precise cutting must be performed during stamping. The present invention is based on the understanding that such precise cutting can be obtained if the profiles to be stamped are sufficiently spaced apart from each other, ensuring sufficient resistance during cutting at the material bridging portions between the two profiles. Alternatively, if two workpiece profiles are produced in a single cut, a precise cut profile can be generated. The following transmission mechanism allows for a corresponding arrangement of the transmission mechanism in which two workpiece profiles can be produced in a single cut.

[0009] The drive link for a saw chain has two openings for the hinge element, a drive protrusion, and a drive link ridge. The drive link is planar and extends in the drive link plane. The drive link has an opening plane that includes the central axis of the opening and extends perpendicular to the drive link plane. The drive link has a transverse plane that is perpendicular to the opening plane and extends centrally between the central axes of the two openings. The drive link has a longitudinal axis that extends in the drive link plane and intersects the central axis of the opening. The drive link ridge is asymmetrically constructed with respect to the transverse plane. The drive link has an upper side facing away from the opening plane, which at least partially extends at the drive link ridge. A functional surface and a contact surface spaced apart from the functional surface are provided on the upper side of the drive link. The functional surface is constructed on the drive link ridge and includes an upper section in which the upper side has the maximum distance from the opening plane. The functional surface on the upper side of the drive link is symmetrically constructed with respect to the contact surface about a point of symmetry in the direction of view towards the drive link plane.

[0010] This invention configures the geometry of the transmission links such that their stamped profiles can contact each other. Through a point-symmetric design of the contact surface and functional surface of the transmission links, two transmission links can be arranged such that they contact each other at their upper sides. Here, the functional surface of one transmission link contacts the contact surface of the other transmission link. Furthermore, the contact surface of one transmission link contacts the functional surface of the other transmission link. Thus, the stamped profiles of the transmission links are compactly arranged across the width of the sheet metal strip, thereby increasing the output of transmission links manufactured for each sheet metal strip and reducing the production cost of the transmission links. Because the transmission links are directly arranged, the profiles of two transmission links can be produced in a single cut. Therefore, during the manufacturing process of the transmission links, small manufacturing tolerances can be maintained even with a large number of parts.

[0011] Advantageously, the upper functional surface extends at a depth measured in a direction perpendicular to the opening plane, wherein the depth corresponds to at most 20%, and especially at most 10%, of the maximum distance between the functional surface and the opening plane. Thus, the functional surface is the upper section of the transmission link that contacts the bottom of the cut when cutting the material and serves as a depth limiter for the cut.

[0012] Preferably, the length of the functional surface measured in the direction of the longitudinal axis is at least 15%, and especially at least 25%, of the length of the transmission link measured in the direction of the longitudinal axis.

[0013] Preferably, the upper side of the transmission link has a first intermediate section and a second intermediate section, wherein the first intermediate section extends from the functional surface to the symmetrical point and the second intermediate section extends from the symmetrical point to the abutting surface.

[0014] The first and second intermediate sections are advantageously constructed such that, when the two transmission links are arranged relative to each other, their upper sides contact each other and their symmetrical points overlap, without forming a Zwickel between the upper intermediate sections. In an alternative construction of the transmission links, the first and second intermediate sections are particularly constructed such that, when the two transmission links are arranged relative to each other, their upper sides contact each other and their symmetrical points overlap, with a Zwickel between the upper intermediate sections having a minimum radius of at least 1.5 mm, preferably at least 1.65 mm. Preferably, the radius of the Zwickel is at least 1.5 times the thickness of the sheet metal or the width of the transmission link. Therefore, if the upper side should have an asymmetrical section, the resulting Zwickel should have a corresponding minimum radius. In other words, the diameter of the Zwickel is at least 3 mm. Due to the predetermined minimum size of the Zwickel, precise cutting of the Zwickel is possible.

[0015] Advantageously, the first intermediate section is constructed symmetrically with respect to the second intermediate section about at least a portion of the symmetry point in the direction of view towards the plane of the transmission link. Preferably, the first intermediate section is constructed symmetrically with respect to the second intermediate section about the symmetry point in the direction of view towards the plane of the transmission link. If there is complete symmetry on the upper side, no shoulder is generated on its upper side when the two transmission links are arranged. This greatly simplifies the manufacturing process because it is not necessary to punch out the shoulder during the preceding stamping process. Preferably, the functional surface, the first intermediate section, the second intermediate section, and the abutment surface form the upper side of the transmission link.

[0016] Preferably, the upper side has a length measured in the direction of the longitudinal axis, wherein the length of the upper side corresponds to at least 65%, particularly at least 75%, and preferably about 85% of the length of the transmission link. As the length of the upper side increases, scrap material between multiple transmission links arranged with each other or between their stamped profiles is reduced.

[0017] The symmetrical points are preferably located between the central axes of the openings in the direction of the longitudinal axis, especially between the openings, and particularly advantageously centrally between the openings. Advantageously, the symmetrical points are spaced from the transverse plane at a distance less than 10% of the length of the transmission link, especially less than 5%. The more centrally the symmetrical points are arranged about the longitudinal axis, the more compactly the transmission links can be arranged relative to each other.

[0018] Advantageously, the transmission element is configured such that it has a first end side at one longitudinal end and a second end side at the other longitudinal end, wherein the profiles of the two end sides are identically constructed in a viewing direction perpendicular to the plane of the transmission element. Alternatively, the profiles of the two end sides can be oriented parallel to each other in a viewing direction perpendicular to the plane of the transmission element. Furthermore, it is suitable that the profiles of the two end sides are identically constructed and oriented parallel to each other in a viewing direction perpendicular to the plane of the transmission element. In a particularly preferred embodiment, the end sides of the transmission element are oriented parallel to the transverse plane. By constructing the above features, two transmission elements or their stamped profiles can be arranged such that their end sides are at least partially, preferably completely, in contact. Therefore, two transmission elements can be arranged such that the first end side of one transmission element contacts the second end side of the other transmission element, forming a unique cutting profile. Thus, a compact arrangement of the stamped profiles in the direction of the longitudinal axis of the transmission element can also be obtained.

[0019] Another object of the present invention is to describe an arrangement of multiple transmission links that allows for cost-effective manufacturing of saw chains.

[0020] This objective is achieved through an arrangement of multiple drive links for a saw chain, the arrangement having at least four identical drive links according to the drive links for the saw chain, wherein each drive link has two openings for a hinge element, a drive protrusion, and a drive link ridge, wherein the drive link is planarly constructed and extends in a drive link plane, wherein the drive link has an opening plane that includes the central axis of the opening and extends perpendicular to the drive link plane, wherein the drive link has a transverse plane that is perpendicular to the opening plane and extends centrally between the central axes of the two openings, wherein the drive link has a longitudinal axis that extends in the drive link plane and intersects the central axis of the opening, wherein the drive link ridge is asymmetrically constructed with respect to the transverse plane, wherein the drive link... The moving link has an upper side facing away from the opening plane, which at least partially extends at the raised portion of the transmission link. A functional surface and a contact surface spaced apart from the functional surface are provided on the upper side of the transmission link. The functional surface is constructed on the raised portion of the transmission link and includes an upper section in which the upper side has a maximum distance (a) from the opening plane. The functional surface on the upper side of the transmission link is symmetrically constructed about a point of symmetry with respect to the contact surface in the view direction of the transmission link plane. Each transmission link has a first end side at one longitudinal end and a second end side at the other longitudinal end. Two transmission links contact each other on their respective upper sides and at their respective end sides. The transmission link surrounds a central shoulder with its contour between the upper and end sides.

[0021] Of course, the advantages of the transmission element according to the invention mentioned above also apply to this arrangement. Furthermore, it is advantageously configured that the minimum radius of the intermediate shoulder is at least 1.5 mm. Therefore, the transmission element can be manufactured with low tolerances.

[0022] The embodiments of the present invention will now be explained with reference to the accompanying drawings. Wherein: Figure 1 A perspective view of a section of a saw chain for a motorized saw with a transmission element according to the invention is shown. Figure 2 A side view of the transmission element according to the present invention is shown. Figure 3 It shows that according to Figure 2 Rear view of the transmission system. Figure 4 The transmission link is shown along Figure 2 A cross-sectional view of line IV in the diagram, and Figure 5 A side view showing the arrangement of multiple transmission links. Detailed Implementation

[0023] exist Figure 1 The diagram shows a section of a saw chain 1 for use in work implements, particularly for motorized saws. The saw chain 1 is constructed from a cutting link 2, a connecting link 3, and drive links 4 and 5. The drive links 4 and 5, the cutting link 2, and the connecting link 3 are hinged together via hinge elements 7, particularly riveting bolts. The saw chain 1 has a travel direction 8, in which it must be mounted on the motorized saw to cut materials such as wood. The drive links 4 and 5 are arranged in the middle of the saw chain 1, and the connecting link 3 is located on the outside of the drive links. In an embodiment, each drive link 4 and 5 has a drive protrusion 9 for engaging with the drive link of the motorized saw. The drive links 4 and 5 have a rear opening 13 and a front opening 13' with respect to the travel direction 8. Figure 2 The rear openings 13 of the transmission links 4 and 5 are respectively connected to the front rivet openings of the connecting links 3, and the front openings 13' of the transmission links 4 and 5 are respectively connected to the rear rivet openings of the connecting links 3. Viewed in the travel direction 8, a cutting link 2 is arranged for every two connecting links 3 instead of a connecting link 3. The cutting links 2 are alternately arranged on the longitudinal side of the saw chain 1. The cutting links 2 have cutting teeth 11, which are forward-positioned with a depth limiter 19 about the travel direction 8. The cutting teeth 11 are used to remove the material by cutting. Adjacent to the depth limiter 19, a transmission link ridge 6 is provided at the adjacent transmission link 5 to reinforce the depth limiter 8. An alternative structure for the saw chain 1 can also be provided.

[0024] exist Figure 2 The diagram shows a transmission link 5 with a transmission link protrusion 6. The transmission link 5 has two openings 13, 13', namely a rear opening 13 and a front opening 13'. Furthermore, the transmission link 5 includes a transmission protrusion 9, at which the lower side 32 of the transmission link 5 extends at least partially. Figure 4 As shown, a lubricant channel 33 is constructed at the transmission link 4, which is connected to the openings 13, 13'. During the operation of the saw chain 1, lubricant reaches the riveting bolt 7 via the lubricant channel 33.

[0025] exist Figure 4 The diagram shows a cross-sectional view of the transmission element 5 along line IV in the travel direction 8. The planar structure of the transmission element 5 can be clearly seen in the cross-sectional view. The transmission element 5 extends in the transmission element plane 16. Figure 2 and Figure 4 As can be seen, the transmission element 5 has an opening plane 15. The opening plane 15 includes the central axis 14 of the opening 13. The opening plane 15 is oriented perpendicular to the transmission link plane 16.

[0026] like Figure 2 As shown, the transmission link 5 has a transverse plane 17. The transverse plane 17 is oriented perpendicular to the opening plane 15. The transverse plane 17 extends centrally between the central axes 14 of the two openings 13. Furthermore, the transmission link 5 has a longitudinal axis 18, which extends in the transmission link plane 16 and intersects the central axis 14 of the openings 13. The transmission link protrusion 6 is constructed asymmetrically with respect to the transverse plane 17.

[0027] like Figure 2As shown, the transmission link 5 has an upper side 12 facing away from the opening plane 15. The lower side 32 of the transmission link 5 also faces away from the upper side 12. The upper side 12 extends at least partially at the transmission link protrusion 6. A functional surface 22 is provided on the upper side 12 of the transmission link 5. The functional surface 22 is constructed on the transmission link protrusion 6. The functional surface 22 corresponds to a section of the upper side 12 of the transmission link 5 that functionally interacts with the cutting bottom during material cutting, i.e., contacts the cutting bottom and thus acts as a depth limiter for cutting. The functional surface 22 therefore includes a section of the upper side 12 in which the upper side 12 has a maximum distance a from the opening plane 15. Furthermore, the functional surface 22 of the upper side 12 extends at a depth b measured in a direction perpendicular to the opening plane 15. The depth b corresponds to at most 20%, and particularly at most 10%, of the maximum distance a between the functional surface 22 and the opening plane 15. The cutting process is highly dynamic, thus allowing for effective connection of the transmission link 5 not only at the "highest point" of its transmission link protrusion 6 but also in the region adjacent to the "highest point." This region is schematically represented by a boundary line 34 corresponding to the depth b of the functional surface 22. Furthermore, the functional surface 22 has a length c measured in the direction of the longitudinal axis 18, wherein the length c of the functional surface 22 is at least 15%, and particularly at least 25%, of the length d of the transmission link 5 measured in the direction of the longitudinal axis 18.

[0028] like Figure 2 As shown, a contact surface 23 is provided at the upper side 12. The contact surface 23 is constructed on the upper side 12 at a distance from the functional surface 22. The functional surface 22 of the upper side 12 of the transmission link 5 is constructed symmetrically with respect to the contact surface 23 about a point 20 in the viewing direction toward the transmission link plane 16. In a preferred embodiment, the point 20 is located on the upper side 12 of the transmission link 5. Figure 5 As shown, this at least partially symmetrical design of the upper side 12 enables the arrangement of two structurally identical transmission links 5, 5' such that, in the embodiment, the upper side 12 is in complete contact at the functional surface 22 and the abutment surface 23, especially along its entire upper side 12, and particularly continuously in contact at the intermediate sections 24, 25. In the embodiment, the foremost and rearmost points of the upper sides 12, 12' of one transmission link 5 and the other transmission link 5' abut against each other. In an alternative embodiment, it may be suitable that the upper side 12 of the transmission link 5 is constructed such that, in the arrangement, the upper sides 12 of the two transmission links 5, 5' only contact a portion of the functional surface 22 and the abutment surface 23 of the other transmission link 5'.

[0029] like Figure 2As shown, the upper side 12 of the transmission link 5 has a first intermediate section 24 and a second intermediate section 25. The first intermediate section 24 extends from the functional surface 22 to the symmetry point 20. The second intermediate section 25 extends from the symmetry point 20 to the abutment surface 23. In an embodiment, the functional surface 22, the first intermediate section 24, the second intermediate section 25, and the abutment surface 23 form the upper side 12 of the transmission link 5. The upper side 12 here has a length e measured in the direction of the longitudinal axis 18, wherein the length e corresponds to at least 65%, particularly at least 75%, and preferably about 85% of the length d of the transmission link 5. In an embodiment, in the viewing direction toward the plane 16 of the transmission link, the contours of the first intermediate section 24 and the second intermediate section 25 together form a connecting line between the functional surface 22 and the abutment surface 23. The connecting line intersects the symmetry point 20. Therefore, in an embodiment, the first intermediate section 24 and the second intermediate section 25 are also constructed perfectly symmetrically about the symmetry point 20 in the viewing direction toward the plane 16 of the transmission link. Therefore, in an arrangement of two identical transmission links 5, the transmission links are abutted against each other at their upper sides 12 and do not have a shoulder between the upper sides 12. Figure 5 ).

[0030] In an alternative embodiment of the transmission link, also according to the invention, the first intermediate section 24 may be configured to be only partially point-symmetrical about the symmetry point 20 relative to the second intermediate section 25 in the direction of view toward the transmission link plane 16. Therefore, the two intermediate sections 24, 25 will be at least partially asymmetrically constructed. This results in the upper sides 12 of the transmission links 5 only partially contacting each other in an arrangement of two structurally identical transmission links 5 (in which the upper sides 12 of the transmission links 5 are in contact with each other and their symmetry points 20 overlap). Therefore, a shoulder exists between the upper sides 12 of the transmission links 5 in the region of the intermediate sections 24, 25. To still achieve a compact arrangement of the transmission links, the shoulder must be manufacturable. Therefore, the intermediate sections 24, 25 are constructed such that the minimum radius r is at least 1.5 mm. The minimum radius r is in particular at least 1.5 times the width f of the transmission link 5. The width f of the transmission link 5 is measured perpendicular to the transmission link plane 16.

[0031] like Figure 2 As shown, the symmetry point 20 is located between the central axes 14 of the openings 13 and 13' in the direction of the longitudinal axis 18. In a preferred embodiment, the symmetry point 20 is located between the openings 13 and 13' of the transmission link 5. The symmetry point 20 has a distance from the transverse plane 17 that is less than 10% of the length d of the transmission link 5, and particularly less than 5%. In a preferred embodiment, the symmetry point 20 is located in the transverse plane 17.

[0032] like Figure 2 and Figure 4As shown, the transmission link 5 extends along its longitudinal axis 18 from one longitudinal end 27 to the other longitudinal end 29. The transmission link 5 has a first end side 28 at one longitudinal end 27 and a second end side 30 at the other longitudinal end 29. In a preferred embodiment, the end sides 28 and 30 are oriented parallel to each other. Furthermore, the end sides 28 and 30 are oriented parallel to the transverse plane 17. Figure 5 As shown, this allows for the arrangement of two identical transmission links 5,5" such that the end sides 28,28",30,30" contact each other and at least partially, but preferably completely, cover each other. According to... Figure 5 In the arrangement structure, the transmission links 5,5" are arranged in the longitudinal direction 18 such that the second end side 30 of one transmission link 5 contacts the first end side 28" of another transmission link 5.

[0033] In an alternative embodiment of the transmission link 5, the end sides 28, 30 may also have other profiles, particularly curved profiles. In order to still arrange the transmission link 5 such that its end sides contact each other and substantially overlap, the second end side 30 of the transmission link 5 is moved parallel to the first end side 28 of the transmission link. This parallel movement preferably occurs along the longitudinal axis 18 of the transmission link 5.

[0034] like Figure 2 and Figure 4 As shown, the functional surface 22 and therefore the abutment surface 23 are constructed parallel to the opening plane 15. Furthermore, in an alternative embodiment, the functional surface 22 and the abutment surface 23 can be shaped differently. For example, the upper side 12 can have an S-shaped profile. Therefore, the profile can form at least one partial point symmetry between the functional surface 22 and the abutment surface 23.

[0035] like Figure 5 As shown, four identical transmission links 5,5',5",5"' are arranged relative to each other. Two transmission links 5,5',5",5"' contact each other at their upper sides 12,12',12",12"' respectively, and two transmission links 5,5',5",5"' contact each other at their end sides 30,28",30',28"' respectively. Here, the transmission links 5,5',5",5"' surround the intermediate shoulder 26 with their contours between the upper sides 12,12',12",12"' and the end sides 30,28",30',28"'. The contours are constructed such that the minimum radius r of the intermediate shoulder 26 is at least 1.5 mm. The minimum radius r of the intermediate shoulder 26 is preferably also 1.5 times the width f of the transmission link 5.
