以三路分流恒星式减速器为研究对象,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,计算了各个恒星轮以及系统的功率分配率。从静力学角度分析了恒星传动功率分流与基本构件的支撑刚度、误差以及浮动之间的关系,并与行星传动进行比较。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 of a star gearing with three branches are estabished based on the characteristic that the system composes a closed-loop of power flow.In consideration of the parts manufacturing errors,assembly errors,bearing stiffness and float,the power splitting coefficient of each star gear and the system are calculated by using the theory of equivalent mesh error.The relation between the errors,float and the bearing stiffness and power splitting are analyzed from the perspective of statics,and comparing with planetary transmission.A new algorithm is proposed,the reference for the engineering application is provided.
