TOOTHED DISC AND METHOD FOR MANUFACTURING THE TOOTHED DISC

摘要

A novel method of manufacturing a toothed disc is taught wherein the teeth can be cold formed to a relatively high set of tolerances in a relatively time-efficient manner. A cold-formed disc blank with an annular thickened ring about its periphery is forced through a set of tooth forming rollers which engage the annular thickened ring. As the blank is forced through the set of rollers, the rollers cold forming tooth structures in the annular ring. In some circumstances, the tooth structure can be a final desired tooth profile and in other circumstances, the disc blank may be forced through two or more different sets of tooth forming rollers, each set of tooth forming rollers contributing to the forming of the final, desired tooth profile.

1. A method of forming a toothed disc, comprising the steps of:
providing a disc blank disposed about a disc axis; and forming a plurality of teeth simultaneously along a periphery of the disc blank; the forming step including engaging the periphery of the disc blank with a plurality of tooth forming rollers simultaneously, and the tooth forming rollers each rotating about a respective axis which is not parallel to the disc axis.
