以EBZ160掘进机截割部行星减速器为研究对象,建立齿轮传动系统的平移-扭转耦合振动分析模型,运用RecurDyn对其进行仿真实验,研究齿轮的啮合刚度和轴承的弹性变形对减速器动力学特性的影响.仿真结果表明:考虑轴承工作脉动与齿轮工作脉动耦合后,在启动阶段输出轴的转速会出现瞬间的突变,进入稳态阶段后,脉动耦合的影响依然存在,使减速器的输出转速产生了微观的波动;通过仿真结果对行星减速器各级传动中齿轮啮合、轴承外圈与轴承孔座之间的非线性接触力进行了定量分析.仿真结果为行星减速器的动态特性分析提供了可视化数据信息,揭示了耦合振动对减速器动态特性的影响.
Taking EBZ160 TBM’s cutting unit planetary reducer as the research object, the translational-torsional coupled vibration analysis model of gear drive system was established. The RecurDyn model was used to simulate the gear meshing stiffness and the elastic deformation of the bearing. The simulation results show that after the coupling of the working pulsation of the bearing and the pulsation of the gear, the instantaneous sudden change of the rotational speed of the output shaft occurs during the starting phase. After entering the steady state phase, the influence of the pulsating coupling still exists, so that the output of the reducer The rotational speed produced the micro fluctuation; Through the simulation result, the non-linear contact force between the outer race and the bearing seat of the planetary reducer was meshed, and the simulation results were the dynamic characteristics of the planetary reducer Visual data was provided to reveal the influence of coupling vibration on the dynamic characteristics of the reducer.
