In light of the issues such as carrying capacity and the running smoothness of gear with small tooth deference, a new type of a small modules planetary gear reducer with small tooth deference is designed. This new reducer has advantages such as mean load, running smoothly and quickly. In order to reveal its working principle and movement, a three-dimensional model of gear reducer is established by SolidWorks Software; and then the 3D model is imported into ADAMS to achiveve the virtual prototype model. Taking ADAMS software as a platform to complete kinematical and dynamic simulations, the dynamic change rule of the gear mesh force in time-domain and frequency-domain in the process of inside gearing is simulated. The simulation results are roughly in accordance with ones of theoretical calculation, so as to prove the correctness of virtual prototype model. The rationality and reliability are proved on this new planetary gear reducer, which will provide the theoretical guidance for the design of fine-pitch small tooth deference planetary gear reducer.
