The cycloid planetary gear drives designed in the so-called RV-type play an important role in precision power transmission. However, the load analysis of such the reducer type is complicated, because of multiple tooth pairs in contact. The aim of the paper is thus to propose a computerized approach of loaded tooth contact analysis (LTCA) either for the contact tooth pairs of the involute stage or of the cycloid stage. The coupled influences of the loads acting on the involute and the cycloid gears are studied considering the friction on the contact tooth flanks as well as the stiffness of the supporting bearings for the cycloid discs. With an industrial example, the contact characteristics during operation, such as the load sharing and the contact stress distribution can be simulated by the proposed approach. The transmitted torques on the crankshaft, the displacements of the main components and the efficiency of each stage calculated accordingly are also illustrated in the paper.
