margin: 0px; padding: 0px; list-style: none; word-break: break-all;">2,当丝杠或螺母转动时,滚珠沿螺纹滚道滚动,则丝杠与螺母之间相对运动时产生滚动摩擦,为防止滚珠从滚道中滚出,在螺母的螺旋槽两端设有回程引导装置 <span century="" gothic",="" "microsoft="" yahei",="" tahoma,="" verdana,="" arial;="" text-size-adjust:="" none;="" font-size:="" 1rem;"="" style="box-sizing: border-box; margin: 0px; padding: 0px; list-style: none; word-break: break-all;">3,它们与螺纹滚道形成循环回路,使滚珠在螺母滚道内循环. 传动形式根据丝杠和螺母相对运动的组合情况,丝杆升降机基本传动形式有的四种类型. <span century="" gothic",="" "microsoft="" yahei",="" tahoma,="" verdana,="" arial;="" text-size-adjust:="" none;="" font-size:="" 1rem;"="" style="box-sizing: border-box; margin: 0px; padding: 0px; list-style: none; word-break: break-all;">(1)螺母固定、丝杠转动并移动,该传动形式因螺母本身起着支承作用,消除了丝杠轴承可能产生的附加轴向窜动,结构较简单,可获得较高的传动精度.但其轴向尺寸不宜太长,否则刚性较差.因此只适用于行程较小的场合.<span century="" gothic",="" "microsoft="" yahei",="" tahoma,="" verdana,="" arial;="" text-size-adjust:="" none;="" font-size:="" 1rem;"="" style="box-sizing: border-box;
