Gearing production method for producing a rotationally symmetrical gearing part for motor vehicles, especially a single-piece starter ring, has a flange and concentric neck

摘要

On the outer edge of a flange (2) there is a toothed ring/crown gear (7) that extends axially on one side and has teeth (6) sunk in on an outer side. Molded onto the flange, a concentric neck (8) is aligned on-axis opposite to the toothed ring/crown gear. The outer diameter of the neck is smaller than the outer diameter of the toothed ring/crown gear. An outer edge is formed on a circular blank on one side in an axial direction to a circular crown/ring. An independent claim is also included for a rotationally symmetrical gearing part, especially a single-piece starter ring.
