补充资料:机械原理:差动机构
差动机构
将两个有差异的或独立的运动合成为一个运动﹐或者将一个运动分解为两个有差异的运动的机构。差动机构有各种具体型式﹐可以用齿轮﹑螺旋﹑链条或钢索等组成﹐常用於汽车﹑拖拉机﹑起重机﹑测微器和天文仪器等中﹐起增力﹑微动﹑运动分解或合成﹑误差补偿等作用。如在链条差动滑轮中﹐由於重物Q 的提昇决定於P 点的上昇和P 点的下降运动之差﹐故称差动。如大﹑小链轮不固接在一起﹐则Q 的输出运动决定於P 和P 两个独立输入运动﹐遂成为一个2自由度机构。将链轮固接在一起﹐它就成为单自由度机构﹐这时P 和P 只有一个独立运动。将一个运动分解为两个运动的差动机构如汽车后桥差动轮系﹐它容许汽车在转弯时走弯道外圈的后轮比走内圈的转得快些﹐从而保证两轮都在地上滚动﹐避免擦伤轮胎。
