Zahnrad und Welle und Verfahren zu deren Herstellung

摘要

A method for producing a unitary toothed part with a shaft and the resulting products. In the process, a blank (1) is formed. The blank includes a shaft part (9b) and a flange part (1a). The flange part having a thicker outer diameter and a thinner inner diameter. The outer diameter is formed into a tubular part (2a) by drawing. A plurality of teeth (3d) and remnants (3f) are formed by extruding the tubular part. At least one spline (3e) is formed by extruding the shaft part. Through the steps of forming, drawing, and extruding, a blank is made into a unitary part (3) having teeth and a shaft thus increasing precision, rigidity, durability, and reducing forming costs.
