Abstract: In order to solve the dynamic performance problems of gear drive with meshed medium belt, vibration model considering the gear meshing stiffness, error excitation and damping of the belt was established for the dynamic analysis. The finite element model of the gear drive with meshed medium belt was set up in the ANSYS Workbench software based on the solid model made by Solidworks. Then the dynamic performance of two gear systems was compared via the analysis and simulation by ANSYS. The results indicate that the meshed belt can not change the variable regularity of stress during the gear transmission process. The vibration amplitude and vibration cycle of the gear drive with meshed medium belt is decreased and increased respectively compare with the ordinary involute gear drive system. The meshed belt can change the meshing stiffness and meshing damping, and reduce the vibration and noise of the gear drive with meshed medium belt.
