ABSTRACT:
The gearing component, in this case a synchronizer ring with synchromesh gearing for automobile gear boxes, is manufactured by cutting it out of a strip of material with a precision cutting machine, at the same time forming gearing out of radial and at least nearly cuboid projections to be stamped into teeth which have a given ratio of tooth height to minimum tooth width. The excess material or flash formed during the stamping operation is removed with a punching tool. The teeth are deburred in a grinding operation, and the edges are rounded off to a certain extent at least. This method not only permits the extremely economical manufacture of such gearing components; a previously unobtainable precision of tooth shape and hardness is also made possible.
