消除间隙机构,可提高进给丝杠或滚珠丝杠等进给机构的精度。 为克服丝杠中心线与运动部件运动方向不平行,使运动灵活,可预先把螺母座安装孔直径制造的比螺母稍大一些,就可以消除平行度误差。 而由于产生间隙对位置精度的影响,则需另外设置一套消除间隙用的螺母。在移动时,使杠 Elimination of clearance agencies, can improve feed screw or ball screw and other feed mechanism accuracy. To overcome the screw center line and the direction of movement of moving parts is not parallel, so flexible movement, the nut can be pre-installed hole diameter slightly larger than the nut, you can eliminate the error of parallelism. However, due to the influence of the clearance on the position accuracy, a set of nuts for eliminating the clearance need to be additionally provided. When moving, make the bar
