Procedure for making a friction ring for clutches or brakes with a sintered friction lining.

摘要

The production of a friction ring (1) for clutches or brakes, having a sintered friction lining (2), is based on a supporting ring (3) which is stamped from a flat metal plate and is provided with a sintered-on friction lining (2) before the sintered supporting ring (3) is formed into a conical or cylindrical friction ring (1) while at the same time impressing grooves or slots (8), distributed over the circumference, into the friction lining (2). …In order to ensure adequate maintenance of dimensions during this forming process, the supporting ring (3) is formed to correspond to the grooves or slots (8) when they are impressed. ……
