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. When we establish the three?dimensional structure of the Planet?cycloid Reducer model with the software UG，Carry on visual design and virtual assemble and drawing paper．The result of study have the guide meaning to accelerate design speed and quantities of the Planet—cycloid Reducer． Keywords：Planet—cycloid Reducer; Cycloid ; UG 第一章 绪论 在科技飞速发展的今天,产品设计已经进入了一种全新的三维虚拟现实的设计环境中,以往的那种以二维平面设计模式为代表的设计方式已经逐渐退出“历史舞台”,取而代之的是各种先进数字化的三维设计技术。它的应用和发展引起全了社会和生产的巨大变革。 减速器是各种机械设备中最常见的部件,它的作用是将电动机转速减少或增加到机械设备所需要的转速, 摆线针轮行星减速器由于具有减速比大、体积小、重量轻、效率高等优点，在许多情况下可代替二级、三级的普通齿轮减速器和涡轮减速器，所以使用越来越普及，为世界各国所重视。 1.1基本概念 摆线针轮行星传动,简称摆线针轮传动。它与渐开线少齿差行星传动一样，同属于K-H-V型行星齿轮传动。摆线针轮传动的主要特征是：行星轮齿廓为变幅外摆线的内侧等距曲线，中
