Abstract
1437680 Rolling gear teeth LEAR SIEGLER Inc 16 Dec 1974 [28 Feb 1974] 54186/74 Heading B3M A die for finish-rolling the teeth in a workpiece gear has teeth approximately conjugate to those to be formed on the workpiece, but with its teeth having flanks divided substantially equally between ones having smooth uninterrupted surfaces and ones having parallel grooves extending between root and crest. Each workpiece gear tooth is arranged, where possible, to be contacted successively by a smooth and then a grooved flank. In one arrangement, Fig. 1, the die teeth T1 to T9 (shown in developed form and in section) each have one smooth flank and one grooved flank. Tooth T1, for example, has grooves G1 between lands L1, whereas tooth T3 has similar lands offset on a line 20 from those of T1. The grooves may have slightly rounded edges and may be provided in straight or helical die teeth. In an alternative form, successive teeth are either grooved on both flanks or smooth on both flanks. Or the die teeth may be divided into groups of two or more smooth teeth followed by the same number of grooved teeth.
