摘　　要：针对太阳轮和内齿圈双浮动行星齿轮传动装置,应用拉格郎日方程,建立了系统的非线性动力学模型,计算了在动力学条件下双浮动行星齿轮传动系统的载荷不均匀系数,对由于行星轮偏心误差、浮动结构、行星轮个数和齿轮间隙引起的双浮动行星齿轮传动系统的不均载进行了动力学分析,同时,对双浮动行星齿轮传动系统中的主要影响因素对浮动量的影响也进行了分析研究。For a planetary gearing transmission with double floating of sun gear and ring,we apply Lagrange equation to establishing the nonlinear dynamic mathematical model.In consideration of the dynamics of the double-floating planetary gearing transmission,the load sharing coefficient was obtained.The dynamics analysis was carried out for the non-sharing load caused by run-out errors,floating structure,the number of planetary gear and gear backlash.In addition,the effects of the main influence factors on floating displacement are also analyzed.These analyses can be used in the optimal design for improving the load sharing capability of a double-floating planetary gearing transmission.
