摘要: 本文用Fourier级数法求解了三路功率分流恒星式减速系统的运动微分方程,获得了系统的频域和时域响应,计算了系统的动载和载荷在各路传动上分配的动态均匀性以及太阳轮中心的浮动轨迹,包括了各级联接刚度以及各类偏心误差的影响,以定量的分析为减速器改善动态性能的优化设计提供了依据。

Abstract: By using the fourier series method, the motion differe-ntial equations of a star gearing with three branches has been solved.The responses of this system in frequency domain and time domain ha-vc been obtained. The dynamic loads on gear teeth, the' dynamic load-balancing on each star gear and the floating locus of the centre of sungrar have been computed. The influences of connecting stiffnesses andrun-outs on dy namic characteristics of the system have been analyzed.These quantitative analyses can provide the basis of optimal design forimproving the dynamic behaviours of star gearings.
