The new structure adopts double-pitch ball screw, which enhances the bearing capacity and rigidity of the ball screw by increasing the pitch and the number of ball bearings, and improves the problems of oil seepage and noise that are easy to occur in traditional ball screws. At the same time, the performance superiority of the new ball screw is verified by experimental tests. Finally, this paper summarizes the advantages and application prospects of the new ball screw. Keywords: heavy-duty machine tool, ball screw, double pitch, bearing capacity, rigidity, oil seepage, noise., 5. 组装：将滚珠、导轨、外壳等部件组装在一起，形成完整的直线滚珠丝杠, 6. 安装完成后，对轴承进行润滑，确保轴承能够长时间稳定运转,滚珠丝杠螺母无加油孔是指该螺母没有任何油脂或润滑剂的通道或孔洞，无法进行润滑,以下是可能的原因和解决方法： 1. 滚珠丝杠严重磨损：这种情况下需要更换滚珠丝杠, 2. 测量之前需要清洁螺母和丝杠表面，以免影响测量精度, 3. 螺母的内部结构存在问题，例如弹簧失效或变形，导致螺母内部的紧固力不稳定
