Simulation and analysis of contact state between cycloid gear and pin wheels in RV reducer

By using the finite element method, the contact state between cycloid gear and pin wheels of RV reducer is simulated and analyzed. The comparative analysis about the number of contact teeth pairs between cycloid gear and pin wheels, and the maximum values of contact stress under different working loads (output torques) is completed. The results show that the dowel pin hole on cycloid gear has a certain extent influence on the contact state between cycloid gear and pin wheels. With the increase of working load of RV reducer, the deformation quantity of dowel pin hole on cycloid gear also increasing, it makes the number of the contact teeth pairs between cycloid gear and the pin wheels increasing at the same time. Therefore, the deformation of dowel pin hole is beneficial to improve the contact state between cycloid gear and pin wheels.
