传动：非圆齿轮传动传动中至少有一个齿轮的节曲面不是旋转曲面的齿轮传动。一对非圆齿轮嚙合传动时﹐其瞬时传动比按一定规律发生週期变化。图1 非圆齿轮 中两非圆齿轮1和2的节曲线分别为J 1和J 2﹐当两轮嚙合传动时﹐J 1和J 2作无滑动的纯滚动。其瞬时传动比为﹕i12= w1/ w2=r2/r1﹐式中w1和w2分别为两轮的瞬时角速度﹐r1和r2分别为两轮的瞬时向量半径。为了实现非圆齿轮传动﹐也就是保证两轮瞬心轨跡为纯滚动接触﹐必须满足下列两个条件﹕ (1)任何两个瞬时向量半径之和均应等於两轮的中心距a﹐即r1+r2=a﹔(2)节曲线J 2的长度必须是J 1的整数倍。非圆齿轮传动的类型很多﹐机械中常用的是椭圆齿轮传动(图2 椭圆齿轮 )﹐它的节曲线是一对大小相等的椭圆。在椭圆齿轮传动中﹐主动轮等速迴转时﹐从动轮角速度週期性地从最小变到最大﹐又从最大变到最小。此外也可用其他曲线作节曲线﹐如对数螺旋线和卵形曲线等。非圆齿轮传动在机床﹑印刷机﹑纺织机械和仪器中均有应用。
