摘要：
An experimental evaluation of bending fatigue strength for austempered ductile iron (ADI) spur gears have been performed using Zwickfatigue tester. The gear material was manufactured by vertically continuous casting, in which the radius of the graphite grains is smaller. The Stress-Number of Cycles curve (S-N curve) for the bending fatigue strength of the ADI spur gears are manufactured without any specific surface treatments, and have been obtained by post-processing software. It was 9bserved that when the reliability was 50%, thefatigue limit was 304.89 MPa. It has provided a reliable basis to rate the reliability design of the small gearboxes in automation later.
