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.

A driving belt comprising plate elements juxtaposed in its thickness direction and a flat ring fastening the elements annularly. The elements includes at least one adjuster element configured to adjust an endplay as a total of clearances between the adjacent elements in the elements fastened annularly by the ring. The adjuster element comprises an insertion groove opening toward the endplay, and an inserting member inserted into the insertion groove and configured to protrude partially from the insertion groove thereby adjusting the endplay.

A driving belt, which is improved in its torque capacity and durability without being degraded torque transmission efficiency thereof. The driving belt is formed by a plurality of elements 11 juxtaposed in a same orientation, and a ring 12a mounted on a saddle face 17 of the element 11 to fasten the elements 11 in a circular manner. The element 11 comprises: a rocking edge 15 as a fulcrum point of a tilting motion of the element 11 formed in an inner circumferential side of the saddle face 17; and at least one slit formed radially inside of the saddle face to hold a sub ring 12b.
