直线滚动导轨副的装配尺寸关系

Assembly Dimensional Relation in Linear Motion Rolling Guide

给出四方向等载荷型哥德式沟槽直线滚动导轨副的装配关系。说明各参数变化对钢球过盈量变化的误差传递系数及各沟槽中心的位置关系。提出适当选配钢球直径以保证导轨轴与滑块间位置精度的方法。

Assembly has a great influence on the quality of high precise linear motion rolling guide. The dimen-sional relationships in assembling of linear motion rolling guide with gothic groove and equal load in 4 directions is given to expound effects of the parameters change on the error transfering factors of the ball preload change and center of the grooves. The ball diameter must be selected correctly to guarentee the position accuracy between center line of the guide and sliding block.
