Abstract

A non-involute gear (24) used in a gear pair. A first gear has a plurality of radially extending, circumferentially spaced teeth, each with a generally cylindrical, arcuate shaped end surface. A second gear (24) has a plurality of spaced, non-involute shaped teeth. Each tooth of the second gear (24) is formed with opposed base faces (58, 60) disposed at an identical radius. A pair of flats (62, 64) extend in parallel from the ends of each circular base face and terminate in inwardly extending end portions (63, 65) extending from the flats to the top land (56) of each gear tooth (73).
