摘要

为了研究两级行星轮系的动态均载特性,建立了两级行星轮系的平移扭转耦合动力学模型,综合考虑了时变啮合刚度、齿轮安装误差、偏心误差、齿侧间隙及级间耦合等非线性因素,推导了系统的无量纲化动力学方程。采用数值方法对方程组进行求解,对中心构件浮动形式、行星轮误差、级间耦合刚度等因素对系统动态均载特性的影响进行了分析,为两级行星轮系的动力学分析和动态均载特性的研究提供了参考,对两级行星齿轮传动系统的设计有一定的指导意义。

Abstract

To study the dynamic load sharing characteristics of two- stage planetary gear train,a translation- torsion coupling dynamics model is established by taking the nonlinear factors like time- varying mesh stiffness,position error,eccentric error,gear backlash and coupling stiffness into account,and the dimensionless dynamics differential equations for the system are derived and solved by numerical method. The effects of floating components,planetary gear error and coupling stiffness on the load sharing characteristics are analyzed.The research work has guiding significance for the design of multi- stage planetary gear train,and the reference basis for the research of dynamics analysis and dynamic load sharing characteristic of two- stage planetary gear is provided.
