Study on load sharing behavior of planetary gear train based on deformation compatibility

以2K-H行星齿轮传动系统为研究对象,根据整个系统构成功率流动闭环的特点,建立了系统的力矩平衡条件和变形协调条件,并运用当量啮合误差理论,计算了各个行星轮以及系统的均载系数.从静力学角度分析了各构件的制造误差、安装误差以及浮动对行星传动均载性能的影响.提出了一种新的算法,以供工程应用参考.

The deformation compatibility equations and the torque balance equations were found of the 2K-H-type planetary transmission system based on the characteristic that the system composed a closed-loop of power flow.In consideration of the manufacturing error,assembly error and float of the parts,the load sharing coefficient of each planetary gear was calculated by using the theory of equivalent mesh error and equivalent mesh stiffness.The effects of the errors on load sharing were studied.The study provides useful theoretical guideline for the design of planetary gear systems.
