补充资料:传动:摆线齿轮传动
由一对摆线齿轮组成的齿轮传动。摆线齿轮的齿廓由内摆线或外摆线组成 (图中a 摆线齿轮的齿廓 )。滚圆S 在节圆Oj1外面滚动形成齿顶曲线bc ﹐在节圆Oj2内面滚动形成齿根曲线aa'﹔同样﹐滚圆Q 在Oj1内面滚动形成齿根曲线bb'﹐在Oj2外面滚动形成齿顶曲线ad。这样的轮齿接触传动相当於一对大小为Oj1和Oj2的摩擦轮互相滚动。摆线齿轮传动大多用於鐘錶和某些仪器﹐与一般齿轮传动相比﹐它的特点是﹕(1)传动时一对齿廓中凹的内摆线与凸的外摆线嚙合﹐因而接触应力小﹐磨损均匀﹔(2)齿廓的重合度较大﹐有利於弯曲强度的改善﹔(3)无根切现象﹐最少齿数不受限制﹐故结构紧凑﹐也可得到较大的传动比﹔(4)对嚙合齿轮的中心距要求较高﹐若不能保证轮齿正确嚙合﹐会影响定传动比传动﹔(5)这种传动的嚙合线是圆弧的一部分﹐嚙合角是变化的﹐故轮齿承受的是交变作用力﹐影响传动平稳性﹔(6)摆线齿轮的製造精度要求较高。
摆线齿轮传动分内外嚙合和齿条嚙合两种。齿条的齿顶和齿根都是滚圆在直线上滚成的摆线。这种传动还有一些变形齿廓 (图中b 摆线齿轮的齿廓 )。滚圆尺寸对齿根曲线有影响。齿廓Ⅰ的滚圆小﹐齿根部两侧曲线外伸﹔齿廓Ⅱ的滚圆直径恰等於节圆半径﹐内摆线变成一条节圆的半径线。如果再用圆弧代替齿顶的外摆线﹐轮齿即变成圆和直线的组合﹐加工就很方便﹐可用成形铣刀铣削或用衝压等方法製造。针轮传动(图中c 摆线齿轮的齿廓 )的节圆Oj2同时作为齿轮1的滚圆﹐另一滚圆半径为零。当Oj1在Oj2上滚动时﹐圆周上一点a在齿轮 1上画外摆线﹐但由於轮齿要传递运动和力﹐a点要用圆销来代替。这时aa'只是齿轮 1的理论齿廓﹐它的实际齿廓是圆销中心在aa'上运动时所形成的一条等距曲线。如果节圆Oj2的半径变为无穷大﹐针轮变为带有圆柱轮齿的齿条﹐这时齿轮1的齿廓便变为渐开线。
