通过Pro/E三维建模和Abaqus有限元软件仿真分析齿轨轮和销轨在标准节距和标准中心距、最小节距和最大中心距以及最大节距和最小中心距3种工况下的齿轨轮-销轨啮合特性。对比分析仿真结果认为齿轨轮在最大节距、最小中心距啮合时容易导致失效,为了降低齿轨轮失效率,应适当增加齿轨轮啮合中心距。 Through the Pro / E 3D modeling and Abaqus finite element software simulation analysis of the gear wheel and the pin rail in the standard pitch and standard center distance, minimum pitch and maximum center distance and maximum pitch and minimum center distance under three conditions Cogwheel-to-toothed rail engagement characteristics. The result of simulation shows that the gear wheel can easily lose its effectiveness when the maximum pitch and the minimum center distance are meshed. In order to reduce the failure rate of the gear, the meshing center distance of the gear should be increased properly.
