摘要

以分布式电驱动轮毂减速器为对象，应用有限元法求解行星轮轴承支承刚度和柔性销轴支承刚度。将行星轮轴承刚度与柔性销轴支承刚度引入集中参数动力学模型，建立综合考虑行星销轴柔性、时变啮合刚度、时变啮合阻尼、综合误差的动力学模型，探究了均载系数与综合误差、销轴柔度的关系。通过比较两种行星销轴支承结构下行星传动系统的均载系数，表明所提出的柔性销轴结构能够提升系统均载性能。研究结果为行星齿轮减速器均载性能提升及结构优化提供了理论依据。

Abstract

Taking the distributed electric drive hub reducer as study object，by using the FEA method, the support stiffness of the planetary wheel bearing and the flexible pin is solved. The obtained support stiffness are introduced into the lumped parameter dynamics model, a dynamics model that comprehensively considers the planetary pin shaft flexibility, time-varying mesh stiffness, time-varying mesh damping and comprehensive error is established. The relationship between the load sharing coefficient and the comprehensive error and the pin flexibility is explored. Moreover, by comparing the load sharing coefficient of the planetary transmission system under two planetary pin support structures, it shows that the proposed flexible pin structure can improve the system load sharing performance. The results provide a theoretical basis for the performance improvement and structural optimization of planetary gearbox.
