带式啮合介质齿轮传动动力学性能分析

针对带式啮合介质齿轮传动中存在的动力学性能问题，首先建立了考虑齿轮啮合刚度、误差激励、介质带阻尼等参数的带式啮合介质齿轮传动系统简化振动模型，然后利用Solidworks软件对带式啮合介质齿轮传动系统进行了实体建模，最后导入ANSYS有限元分析软件对该模型进行了动力学性能分析仿真。研究结果表明：介质带的存在没有改变齿轮传动过程中的应力变化规律；带式啮合介质齿轮传动相比普通渐开线齿轮传动，其振动幅度减小，振动周期增大，介质带的存在改变了传动系统啮合刚度和啮合阻尼，起到了减振降噪的作用。

Dynamic performance research of gear drive with meshed medium belt

In order to solve the dynamic performance problems of gear drive with meshed mediunl 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 dy- namic 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.
