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.

Abstract: A toothed disc for the adjustment device of a reclining car seat and a method of manufacturing the same. A material strip is placed onto a precision blanking machine. The material strip is stamped so that a portion of the material strip is displaced and formed in a first direction away from the material strip, the portion corresponding to at least one of addendum circle and a hub of a toothed gear. Next, the portion is formed in a direction towards the material strip, whereby the material corresponding to at least one of the addendum circle and a hub of the toothed gear is thickened. Then, a toothed gear is formed in the material strip. Lastly, the toothed gear is blanked from the material strip. All of the aforementioned steps are performed in sequence.
