摘要

以轮毂电机中行星传动系统为研究对象,考虑时变啮合刚度、啮合相位和当量啮合误差等影响因素,建立了系统的运动微分方程,并运用Runge-Kutta法求解得到系统传递误差。基于传递误差曲线,分析了各类误差和支撑刚度变化对系统传递误差幅值的影响,并对误差初相位进行优化。结果表明,误差值的大小与系统传递误差幅值呈正比,误差初相位的变化可以在不改变构件精度的条件下减小系统传递误差幅值,支撑刚度的大小与系统传递误差幅值成反比。研究工作为行星传动系统的设计提供指导作用,降低了制造难度和安装成本。

Abstract

Taking the planetary transmission system of hub motor as the research object,the kinematic differential equations of the system are established by considering the influence factors of time-varying mesh stiffness,meshing phase and equivalent mesh error,and the Runge-Kutta method is used to get the system transmission error. Based on the transmission error curve,the influence of various error and support stiffness on the system transmission error amplitude is analyzed,and the initial phase of the error is optimized. The results show that the magnitude of the error value is proportional to the amplitude of the system transmission error,the change of the initial phase of the error could reduce the transmission error amplitude without changing the component accuracy,the magnitude of the support stiffness is inversely proportional to the amplitude of the system transmission error. The research work has provided guidance for the design of the planetary transmission system,which reduces the manufacturing difficulty and the installation cost.
