摘要
摆线针轮行星减速器作为重要的机械传动部件具有体积小、重量轻、传动效率高的特点。本设计在全面考虑多齿啮合、运转平稳、轮齿均载等运动学和动力学的要求,实现高承载能力、高传递效率、高可靠性和优良动力学性能等指标,而且要便于制造、装配和检修,设计了该具有合理结构的摆线针轮行星传动装置。
本设计建立了合理的动力分析数学模型,对摆线针轮传动中的摆线轮、转臂轴承、柱销及轴进行准确的受力分析,计算并校核主要件的强度及转臂轴承、各支承轴承的寿命,分析结果可以看到,各轴承性能指标均符合要求。

ABSTRACT
The cycloid—gear reducer is one of the most important ponents of the pumping unit by its smaller volume,lighter weight and effective transmission. In order to realize four targets which include high transmission efficiency, high reliability and the excellent dynamics performance and guarantee credible lubricate ability, receive high efficiency of transmission, and make it easy for manufacture, assembly and inspection, we thought over all the requests in the round and design the rational structure cycloid—gear reducer.
In this design,we built the exact force analysis mathematical model of the cycloid—gear reducer, analyzed the forces born by the cycloid-gear, the bearings and the shaft, and produce the Matlab language software analyze of the forces analysis. We analyzed the forces of parts in the cycloid—gear reducer and calculated the intensity and the life of parts. From analyzed the results, we found the parts are our requests.
Key Words:—cycloid Reducer; Cycloid
