On Surface Durability of Involute-cycloid Composite Tooth Profile Gear

Abstract

In a previous paper, the authors have already reported on the design of an involute-cycloid composite tooth profile gear having larger bending and contact strengths than the involute gear. In the present paper, the surface durability of the involute-cycloid composite tooth profile gear is investigated by carrying out a pitting test, and the experimental result explaines the growth of a pitting of this gear. Furthermore, the superiority of the surface durability of the involute-cycloid composite tooth profile gear is confirmed experimentally, compared with the durability of the involute gear measured at the same time.
