On Design Performance of Involute-cycloid Composite Tooth Profile Gear

Abstract

Involute gears have been widely used because of their many advantageous properties. However, involute gears have a drawback that their tooth contact strength is weak, because the convex tooth surfaces contact each other in meshing. In the present study, the authors designed an involute-cycloid composite tooth profile gear having higher bending and contact strengths than those of an involute gear, and confirmed experimentally the superiority of this gear.
