Abstract

When the involute spur gear is working, a large bending stress is generated at the root of the tooth, which is prone to root fracture. In this paper, the double arc transition curve, the arc transition curve and the elliptical arc transition curve are compared. Through the dynamic finite element simulation of Abaqus software, it is concluded that the stress on the elliptical arc transition curve is the smallest. The stress at the root of the tooth can be reduced, the possibility of gear fatigue fracture can be decreased, which providing a certain reference for the design of plastics gears.
