摘 要：
The invalidation of the harmonic gear drive is mostly caused by the fatigue fracture of the flexspline,so determining the stress magnitude and distribution of the flexspline is a key point of the research on flexspline.In this paper a finite element contact analysis model of the flexspline and wave generator in harmonic gearing was established.The analysis produces the stress distribution of the flexspline.The analysis results show that the maximum stress occurs at the region where the tooth rim contacts the wave generator,and the stress distributes symmetrically at the circle direction and is larger at the major axis and the minor axis and at the bottom of the flexspline.
