The harmonic reducer has been widely used in military, industrial and agricultural fields because of its large transmission ratio, high precision, small backlash, stable transmission and small volume and weight. Flexible bearing is a key component of harmonic reducer, and its static mechanical properties are one of the main factors influencing the fatigue life and load carrying capacity of harmonic reducer. Mathematical model of contact force between rolling element and outer ring is established basing on three bending moment equations. This paper takes the CSF-40-80 flexible bearing with double eccentric arc cam as the research object, the finite element methods (FEM) analysis is used to study the deformation and stress of the flexible bearing under no-load and load. The effect of the double eccentric arc cam eccentricity on the stress is also presented, which provides theoretical support for the optimization of harmonic reducers and the manufacture of high-performance harmonic drive systems.
