工作原理 /Operating Principle

QXB系列减速机为二级减速:

一级减速-行星齿轮减速机构

输入轴的旋转从输入齿轮传递到行星齿轮,按齿数比进行减速,为第一级减速;

二级减速-线级减速机构

由行星轮带动旋转的偏心轴驱动两个摆线盘进行偏心运动,摆 线盘成180°对称安装,使其受力均衡。偏心运动促使摆线盘 与放置在针齿壳上的针齿销进行啮合。偏心轴旋转一周,摆线 盘在相反方向上移动一个针齿位。

The QXB is a 2-stage reduction gear:

The first stage—Spur gear reduction

An input gear engages with spur gears that are coupled to crankshafts. Different overall gear ratios can be provided by selecting various first stage ratios

The second stage—cycolidal gear reduction

Grankshafts driven by the epicyclic gears causes an eccen-tric motion of two cycolidal gears that are offset by 180 degrees from one another to provide a balanced load. In the course of one revolution of the teeth of two cycolidal gears move the distance of one pin in the opposite direction of the rotating cranks
