【摘要】 滚动摩擦摆线行星减速器中的齿轮有内外摆线两种齿廓。这两种齿廓曲线特性不同，但都存在过切的问题。理论研究分析表明，只要满足外摆线轮齿廓不过切条件，该传动就不会发生过切。更多还原

【Abstract】 The rolling-friction cycloid speed reducer has two kinds of tooth profiles─a hypocycloid and an epicycloid. Although their characteristics are diffenent, they both have same overcutting problem. By theoretical analysis, a conclusion that the speed reducer can’t be overcutting if its epicycloid gear pnofile is not overcutting is gained.更多还原
