Dynamic Analysis of the Planetary Gear Train in the Cutting Section of the Shearer

摘要: 以分析采煤机截割部行星轮系齿轮的啮合传动特性和行星架的受力情况为目的，利用ADAMS对行星传动系统进行刚体动力学仿真分析，并联合ANSYS对行星架做瞬态分析。仿真结果表明：各级行星齿轮的太阳轮与行星轮的啮合力与理论计算所得结果相近，太阳轮与行星轮在X和Y方向的啮合力呈周期性变化且相位相差90˚；二级行星架的花键连接处和二级行星架侧板根部位置应力较大，为二级行星架的危险位置。仿真结果验证了行星轮系齿轮啮合传动特性，并且得到了二级行星架结构的危险位置，为行星架的设计研究提供了参考。

Abstract: In order to analyze the meshing transmission characteristics of planetary gear system of shearer cutting unit and the force condition of planet carrier, the rigid body dynamics simulation analysis of planetary transmission system is carried out by ADAMS, and transient analysis is done by com-bining ANSYS. The simulation results show that the levels of the meshing forces between the plan-etary gear and sun gear are similar to those of theoretical results. The meshing forces in X and Y direction between sun gear and planetary gear change periodically with a phase difference of 90 DEG. The stresses at the spline join and at the root of the side panel of the secondary planetary frame are larger, which is the dangerous positions. The simulation results verify the gear trans-mission characteristics of the planetary gear train, and provide the basis for the study of planetary carrier to get the dangerous position of the two-stage planetary frame structure, providing a ref-erence for the design and research of planetary frame.
