本文是“浮动盘式渐开线少齿差行星减速器的运动分析一文的继续。选取浮动盘中心点O_3为基点,导出了浮动盘的动、定瞬心迹的方程式。并进一步讨论渐开线少齿差传动中的速度问题。一、浮动盘的动、定瞬心迹选浮动盘中心点O_3为计算基点,坐标系O_3XY和浮动盘团结在一起。起始位置时坐标 This article is the continuation of the motion analysis of the floating disc involute less toothed differential planetary reducer.On the basis of the central point of the floating disc O_3 as the base point, the equation of the moving disc and the moving center of the floating disc is deduced.The involute Less teeth difference in the speed of the transmission problem .First, the floating disk of the move, set the instant heart track election floating disk center O_3 for the calculation of the base point, the coordinate system O_3XY and floating disk unity together. The starting position coordinates
