中文摘要：

针对复合行星轮系均载特性的问题,以Ravigneaux式复合行星轮系统的典型结构为研究对象,基于ADAMS建立了系统的虚拟样机模型,通过对齿轮动态啮合力进行仿真分析,计算出了各啮合副的均载系数,分析了齿轮偏心误差、负载以及输入转速对于系统均载性能的影响。研究结果表明：增加偏心误差、提高转速会降低系统的均载性能;当行星轮偏心误差呈辐射状对称时,系统的均载性能会得到极大提高;太阳轮s1偏心误差对于系统均载性能的影响较s2偏心误差的影响更为明显;增加负载能提高系统的均载性能。

英文摘要：

In order to study the load sharing characteristics of compound planetary gear sets, a virtual prototype of the typical structure of Ravigneaux compound planetary gear train sets was set up based on ADAMS software. By the simulation analysis of the dynamic gear meshing force, the load sharing coefficients of the gear sets were calculated, and the impact of gear eccentric errors, load and input speed on the load sharing characteristic were analyzed. The research results show that the increase of gear eccentric error or the speed of rotation will exacerbate the uneven load of the system. By reasonable distributing the errors of the planet gears in radial symmetry, it will be able to reduce the effect of mesh errors of the planet gears. The load sharing coefficients of the system is more sensitive to the eccentric error of sun gear 1 than sun gear 2. Heavy load makes the load sharing performance better.
