Transmission Design and Kinematics Simulation of Fixed Gear and Planetary Gear

Abstract

Based on the theory of 2K-H planetary gear ransmission, a fixed-axis gear planetary gear transmission scheme is designed, the gear meshing parameters are determined, and the theoretical transmission ratio and output speed are calculated. The 3D model software UG NX8.0 is used to build the solid model, and the virtual prototype model is built based on ADAMS 2013 and the kinematics simulation is carried out. The simulation results are compared with the theoretical values. The results show that the errors of speed and gear ratio are 0.43% and 0.50%. The correctness of the design parameters and the credibility of the virtual prototype model are validated, which lays the foundation for further research on the dynamic characteristics of the planetary gear mechanism.
