[前言]双摆线滚子行星传动的典型结构如图2(A)的正视简图所示。具有短幅外摆线等距曲线轮廓(即外齿齿廓)的内圈通过滚动轴承坐在与输入轴固连在一起的偏心轴上,当输入轴转动时,内圈作行星运动,相当于摆线针轮减速器中的摆线轮。安装着N个滚子的滚子保持架也随着内圈的行星运动作行星运动,相当于摆线针轮减速器中的针轮和针轮架,但滚子保持架不象针轮架那样做定轴轮,而是行星轮。具有短幅内摆线等距曲线轮廓(即内齿齿廓)的外圈,作为定轴轮。这样各个滚子即作为内齿齿廓与内圈外齿廓相啮合传动又作为外齿齿廓与外圈内齿廓相啮合传动,在以后啮合原理的证明中我
[Preface] The typical structure of a double-cycloid planetary transmission is shown in front view in Figure 2 (A). The inner ring with a short-edged equidistant profile of the outer cycloid (ie, the outer tooth profile) sits on an eccentric shaft that is fixedly connected to the input shaft through a rolling bearing. When the input shaft rotates, the inner ring makes planetary motion equivalent to Cycloid reducer in the cycloid. Roller cages mounted with N rollers also make planetary motion with the planetary motion of the inner ring, which is equivalent to the pin wheel and pin carrier in the cycloid gear reducer, but the roller cage does not resemble a pin carrier That fixed-axis wheel, but the planetary wheel. The outer ring with a short-pitch hypocyclical isometric curve profile (ie, inner tooth profile) serves as a fixed-axis wheel. So that each roller as the internal tooth profile and the inner ring gear meshing meshing external gear tooth profile and outer ring meshing meshing transmission in the proof of the principle of engagement I
