Abstract: The effective contact area and circumferential load distribution of cycloid gear tooth surfaces under specific loads were calculated by taking into account the elastic deformations and backlash of cycloid tooth surfaces. A mathematical model of contact stress in the tooth width direction of cycloidal gears was established by using force balance equation and deformation coordination equation, and the calculation procedure and flow chart were given. The mathematical model was a nonlinear equation set, by solving the nonlinear equations, the stress distribution and contact width in the tooth width direction of cycloidal gears were obtained. The mathematical model of contact stress and computational procedures were given to simulate the contact tooth width and contact stress distribution of cycloidal gear under ideal conditions and alignment errors. And the correctness and feasibility of the proposed method were verified by combined with testing and simulation results.
