补充资料:传动:摆线针轮传动
由外齿轮齿廓为变态摆线﹑内齿轮轮齿为圆销的一对内嚙合齿轮和输出机构所组成的行星齿轮传动。除齿轮的齿廓外﹐其他结构与少齿差行星齿轮传动相同。摆线针轮行星减速器的传动比约为6~87﹐效率一般为0.9~0.94。图 轮齿曲线的形成 为轮齿曲线的形成原理。发生圆在基圆上滚动﹐若大於r1﹐M'点画出的是长幅外摆线﹔若小於r1﹐M''点画出的是短幅外摆线﹔用这些摆线中一根曲线上的任意点作为圆心﹐以针齿半径rz为半径画一系列圆﹐而后作一根与这一系列圆相切的曲线﹐得到的就是相应的长幅外摆线齿廓或短幅外摆线齿廓﹐其中短幅外摆线齿廓应用最广。用整条短幅外摆线作齿廓时﹐针轮和摆线轮的齿数差仅为1﹐而且理论上针轮有一半的齿数都与摆线轮齿同时嚙合传动。但如果用部分曲线为齿廓就可得到两齿差和三齿差的摆线针轮传动。用长幅外摆线的一部分作轮齿曲线时﹐其齿廓与圆近似﹐并与针齿半径相差不大﹐因此可用它的密切圆弧代替。摆线针轮传动的优点是传动比大﹑结构紧凑﹑效率高﹑运转平稳和寿命长。
