摘　　要：针对掘进机二级行星减速器传动特点,在一定的假设条件下,建立了单级齿轮传动模型;考虑到第1级的行星轮架和第2级的太阳轮可视为弹性连接,由此确立了两级之间的耦合关系,建立了二级行星轮系的耦合扭转动力学模型。并利用Lagrange方程得到了其数学模型,建模过程中考虑了时变刚度、啮合刚度、齿圈切向支撑刚度及齿轮啮合部位的静态传递误差。振动模型为进一步研究掘进机二级行星减速器的振动特性,解决工作中出现的破坏问题奠定了基础。According to the two stage planetary reducer transmission characteristics of roadheader, a single stage gear transmission model is established under certain assumptions; Considering the first planet wheel rack and the second round of the sun can be seen as elastic connection, which established the coupling relationship between the two stages, established the two planetary gear train coupling torsional dynamics model. And got the mathematical model using Lagrangc equation, considering the time-varying stiffness meshing stiffness of ring gear tangential support stiffness and gear mesh parts of the static transmission error in the modeling process. The vibration model laid the foundation for further study on two stage planetary reducer vibration characteristics and solving the problem of failure in the work of roadheader.
