|
Abstract:
本文建立了单排2K-H型行星齿轮减速机的动力学模型，推导了其振动微分方程。以某实验用减速机参数为仿真参数，对支撑刚度对行星齿轮传动系统均载特性的影响规律进行了仿真研究。结果发现：采用较小的太阳轮轴承支撑刚度可以优化系统内啮合副的均载特性，较小的支撑刚度，就意味着中心件具有一定的浮动效果，从而可以优化均载特性。
In this paper, the dynamics model of a single-row 2K-H planetary gear reducer is established, and its vibration differential equations are derived. Using the parameters of an experimental gearbox as simulation parameters, a simulation study was conducted on the influence law of support stiffness on the equal load characteristics of the planetary gear transmission system. It is found that the use of a smaller support stiffness of the sun wheel bearing can optimize the equal load characteristics of the internal meshing pair of the system, and a smaller support stiffness means that the center member has a certain floating effect, which can optimize the equal load characteristics.
