以上是无切削力滚珠丝杠选型计算需要考虑的因素，具体选型还需要根据具体应用要求进行分析和评估, 4. 更换：如果滚珠丝杠已经严重磨损或损坏，需要及时更换，以避免影响设备的正常运转,因此，在选择滚珠丝杠传动机构时，需要根据具体应用需求来确定适当的螺距、转速和负载范围，以确保传动机构的速度满足要求, 2. 定期加油脂，保持润滑, 关键词：重载机床，滚珠丝杠，双导程，承载能力，刚度，渗油，噪音 Abstract: Based on the performance requirements of heavy-duty machine tool ball screw, a new type of ball screw structure is designed by improving the traditional ball screw. 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.,在选择滚珠丝杠时，还需要考虑负载能力、精度等因素，以保证设备的正常运行和使用寿命,该升降机广泛应用于工业生产线、仓库货架、车站、码头、机场等场所，用于物料的升降、运输和堆垛,滚珠丝杠材质的特点包括： 1.高强度：滚珠丝杠材质通常采用高强度合金钢或不锈钢，具有较高的强度和硬度, 5. 噪声：伺服电机滚珠丝杠的噪声对机器设备的工作环境和操作人员的健康都有影响，应选择噪声低、振动小的滚珠丝杠产品，同时注意安装和维护的规范, 2. 打开滚珠丝杠端盖，找到间隙调节螺母，通常位于滚珠丝杠上部或下部
