| Abstract: | This paper analyzes accurately the load distribution among gear teeth by Ansys Workbench and establishes the model of contact deformation angle of the cycloidal gear.Firstly,the transmission principle of RV reducer and the forceon the tooth surface during the meshing process of the cycloid planetary gear are analyzed.Secondly,the tooth contact between the modified cycloid gear and the pin wheel is analyzed by the finite element method and related engineering software.Then the load distribution between teeth is further analyzed based on kinematics and Hertz theory.Finally,the concept of contact deformation angle of the cycloidal gear is proposed and its finite element calculation is carried out,which can provide the basis for improving the dynamic characteristics and transmission accuracy of RV reducer,prolonging service life and ensuring its stability. |
