MANUFACTURE OF FRICTION PLATE, SYNCHRONOUS BLOCKER-RING, ETC.

摘要

PURPOSE: To easily mount friction lining on a supporting body at a low cost by removing edges on the radial inner side or the outer side of a groove after removing the friction lining and mounting a plate connected by the edges on a supporting body. CONSTITUTION: While a friction plate is composed of a supporting plate 1 including an interior spline 2 and a friction lining 3 and the lining 3 is equipped with a plurality of grooves or slots 4, the lining 3 part is removed up to the plate passing the lining at the grooves or the slots 4. The grooves 4 are opened toward the inner end 5. In the case where both ends of the grooves 4 are opened, the grooves 4 are stamped so that the lining edges 8 edges may be retained in order to maintain the positions of each portions 7 of the lining 3 when the lining 3 is mounted on a supporting plate 1 and the edges 8 are removed for the first time after the lining 3 is mounted on the supporting plate 1.
