为解决限位板-限位销磨损问题,通过Solidworks软件对EBZ-260型掘进机截割减速器第1级太阳轮进行三维精确建模,模拟真实的载荷情况,利用Solidworks Simulation对三维模型进行有限元静力学分析,进而得出第1级太阳轮花键齿部变形,带入轴向力计算模型计算得出太阳轮所受轴向力,最后分析了影响轴向力的其他因素计算求得总轴向力,为限位板-限位销磨损量数值分析模型提供了精确载荷数据。 In order to solve the problem of the wear of the limit plate and the stopper pin, Solidworks software was used to 3D modeling the first-stage sun gear of EBZ-260 roadheader cutting reducer to simulate the real load condition. Solidworks Simulation was applied to the 3D model Finite element static analysis, and then get the first level of the sun gear spline tooth deformation, into the axial force calculation model calculated by the sun gear axial force, and finally analyzed the impact of axial force calculation of other factors The resultant axial force provides accurate load data for the numerical analysis of the limit plate-stop pin wear.
