摘　　要：The hypocycloid RV reducer is a new type of rotor vector(RV) reducer based on the principle of internal cycloidal planetary transmission. The reducer has a compact and hollow structure. First of all, the component composition, special structure and transmission principle are analyzed. Then, the three-dimension dynamic model for the hypocycloid RV reducer was simulated. Through reasonable assumptions, the dynamic environment was defined, the dynamic model was simplified, and the kinetic equations were listed. The torsional stiffness of the shaft component is calculated, and the meshing rigidity of the cycloidal gear and the needle tooth is calculated. Finally, by using MATLAB software to solve the dynamic equations, combined with the actual parameters of the hypocycloid RV reducer, through the solving equation to obtain the natural frequency of the system, which laid the foundation for the design and research of the following hypocycloid RV reducer.The hypocycloid RV reducer is a new type of rotor vector(RV) reducer based on the principle of internal cycloidal planetary transmission.
