普通车床溜板箱与溜板装配尺寸链的一个封闭环为溜板箱齿轮与溜板横进给齿轮传动中心距N，如右图所示，其精度直接影响齿轮副啮合侧隙的大小，其调整方法主要是改变溜板上的孔与溜板箱上螺孔两轴心线之间的偏移量e的方向与数值。这样，封闭环N与组成环的线性尺寸A1、A2、A3、A4 Ordinary lathe slide box and slide assembly dimension chain of a closed ring for the slide box gear and slide cross feed gear drive center distance N, as shown on the right, the accuracy of a direct impact on gear meshing backlash size, The adjustment method is mainly to change the direction and value of the offset e between the hole on the slide and the screw hole on the slide box. In this way, the closed loop N is associated with the linear dimensions A1, A2, A3, A4 that make up the loop
