摘要:
If the slot width is reduced with a decrease in the number of laminated plates of a ring, a die stress sharply increases, thereby hindering production. Elements satisfy (h/t) 40, where h is a slot width of the elements, t is a plate thickness thereof, and S is a head area thereof. Even if the slot width h is reduced, increasing the head area reduces a hydrostatic pressure applied in a punching process, and thus, reduces the load on a die. The present invention is preferably used in endless metal belts in which elements having a width on a pitch line of 24 [mm], and a ring is formed by laminating six plates.

The invention relates to a transverse element (32) for a drive belt (3) for a continuously variable transmission, with an opening (33) extending between a front side (37) and a rear side (38) of the transverse element (32), through which opening a pulling element (31) of the drive belt (3) can be passed, a web part (34) of the transverse element (32) situated below the opening (33) at the position of the opening (33) being provided with a radially upwardly directed bearing surface (42) which forms the lower side of the opening (33), and which in the peripheral direction of the pulling element (31) is provided with an asymmetrical surface contour, a highest point or part (B) of which is situated closer to the front side (37) than to the rear side (38) of the transverse element (32). The transverse element (32) on its rear side (38) in this case is provided with a projecting protuberance (40) and on its front side (37) is provided with a recessed depression (41) which is provided substantially concentrically relative to the protuberance (40).
摘要:
Transverse element (63) for a drive belt for a continuously variable transmission, which element is provided with a recess (64) with a nominal height Hn for at least partially accommodating a set of rings (61) of the drive belt and with a tilting region (70), which forms a transition between a top part of the transverse element (63) with a substantially constant, nominal thickness Dn of the transverse element (63) and a bottom part thereof, the thickness of which decreases in the radially inward direction to a smallest thickness Dm of the transverse element (63), for which purpose a first main plane of the transverse element (63) is oriented at an acute angle ϑ with respect to a second main plane. The nominal thickness Dn, the smallest thickness Dm, the nominal height Hn and said angle ϑ are matched to one another in such a way as to prevent two or more of the transverse elements (63) becoming jammed together during the drive belt manufacturing process.
摘要:
A metal V-belt (25) includes a plurality of metal elements (42) supported by a metal ring (41). The metal ring (41) includes front and rear main surfaces (50r), a pair of left and right slots (45) that receive the metal ring (41) therein, the slots (45) being defined between a saddle surface (54) and an ear-part bottom surface (55). A protrusion (53f) is provided on one of the front and rear main surfaces (50r), and a concavity (53r) is provided in the other of the front and rear main surfaces (50r). A clearance ( d ) defined between an outermost peripheral surface of the metal ring (41) and the ear-part bottom surface (55) of the metal element (42) is set to a value that at an exit of a driven pulley (21), contact of the innermost peripheral surface of the metal ring (41) with the saddle surface (54) of the metal element (42), and contact of the protrusion (53f) of a succeeding metal element (42) and the concavity (53r) of a preceding metal element (42) is avoided.
摘要:
A metal ring polishing method and device capable of polishing the lateral end edge of a metal ring without performing barrel polishing or polishing by a grindstone. Subsequent to loading process for loading a metal ring (W) by a loading means (6), a first blush polishing process is performed for polishing one end edge of the metal ring (W) by a polishing brush (60). Then, a reversing process is performed for reversing the metal ring (W), having its one end edge polished by the first brush polishing process, by a reversing means (10). Subsequently, a second blush polishing process is performed for polishing the other end edge of the metal ring (W), reversed by the reversing process, by a polishing brush (60). And a sweep-out process is performed for sweeping out the metal ring, having the other end edge polished by the second blush polishing process, by a sweep-out means (7).
