ABSTRACT:
In a method of making a rotation-symmetrical gear member, an outer edge of a circular blank is shaped to form a concentric thickened area which extends in axial direction to thereby realize a ring structure. A remaining area of the circular blank is then shaped into a cap-like structure through application of compressive forces by means of a pressure roller such that the ring structure adjoins a sidewall of the cap structure and projects outwardly in radial direction. The ring is then formed with outer teeth in opposition to the sidewall.
