滚珠丝杠副滚动体自旋运动分析

The analysis of ball spin motion for ball screw assembly

滚珠丝杠副滚动体自转运动中包含自旋和纯滚动,滚动体的自旋运动造成滚动体滑动。利用角接触轴承旋滚比的概念和目前对滚珠丝杠副自旋运动的研究情况,采用运动分析的方法分析了丝杠公称直径、接触角和螺旋升角对滚珠丝杠副自旋运动的影响情况,为设计和选用滚珠丝杠副参数提供了参考。

Ball screw roller′s rotary motion contain spinning and pure rolling,the spinning can lead roller to slide.Base on ratio of spinning and rolling from angular contact bearing and knowledge of currently research for ball screw roller spinning,the factors affected roller spinning including nominal diameter,lead angle and contact angle are analyzed by use of motion analysis,it provides reference for designing and parameters selection to ball screw assembly.
