摘　　要：设计了一种应用于星轮式爬楼梯轮椅的差动行星齿轮翻转爬升传动系统,并根据翻转爬升传动系统在爬楼梯轮椅中空间尺寸限制及爬楼梯性能要求,完成了传动比要求下各轮齿数的分配;同时为改善传动质量,对齿轮齿形参数进行了修正。采用SolidWorks软件建立了其三维实体模型,并利用SolidWorks Motion对行星齿轮传动以碰撞接触进行仿真分析,验证各轮齿传动及啮合情况,将SolidWorks Motion的输出结果输入到SolidWorks Simulation中,对输出中心齿轮轮齿进行有限元分析,验证其满足承载能力要求,也为进一步优化结构设计提供了理论依据。A differential planetary gear for flip climbing transmission system which is applied to the star-climbing wheelchair is designed. According to the space limitation and the stair climbing per- formance requirements of climbing transmission system in the stair climbing, the tooth number distrib- uting for each gear under transmission ratio requirements is accomplished. Furthermore, the tooth profile parameters on each gear are modified for improving the quality of the transmission. By using SolidWorks software, the three-dimensional model is established. Then impact and contact simulated analysis is carried out based on the SolidWorks Motion Plugins, and the transmission and meshing con- dition is verified. At the same time, the SolidWorks Motion output result is as input to the SolidWorks Simulation. Through the simulation results, the output center gear tooth can meet the carrying capaci- ty requirements is validated. On the other hand, it also provides theoretical basis for further improve the structure design.
