Analysis of modal vibration characteristics of cycloidal wheel and planetary frame assembly in RV reducer

In order to solve the vibration problem of cycloidal wheel and planetary frame in the process of RV reducer transmission, finite element analysis software ANSYS Workbench was used to carry out constraint modal analysis. By analyzing the first 12 order frequency and mode nephogram of cycloidal wheel and assembly, it is found that the weak links are located in the tooth output axis of cycloidal wheel respectively. The meshing frequency of the gear and the rotation frequency of the planetary frame are calculated and compared with the first order frequency to verify that the cycloidal wheel and the assembly do not resonate.
