Method of shaping a helical gear, and a pinion cutter used therein.

摘要

A pinion cutter for making a helical gear has a number Z of teeth expressed by the equation: <MATH> where L = lead; PHI = angle of twist; and mn = module; and includes a peripheral portion from which any incomplete tooth has been removed in the event Z is not an integer. A method employing this pinion cutter to make a helical gear is also disclosed.
