3. 使用锁紧胶将滚珠丝杠固定在支架或机身上, 在丝杠滚珠模型中，丝杠和滚珠之间的接触面积非常小，因此滚珠的滚动摩擦损失非常小，使得丝杠滚珠模型具有很高的传动效率和精度,您可以在这些市场或者相关的电商平台上搜索购买,其中，热处理是非常重要的一步，可以提高滚珠丝杠的硬度和耐磨性，从而提高其使用寿命和精度,临清滚珠丝杠是一种机械传动部件，主要用于机床、自动化设备、汽车工业等领域,由于滚珠丝杠型号繁多，根据不同的应用场景和使用要求，选择的型号也不同, 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., 3.高刚性：滚珠丝杠螺母机构具有高刚性的特点，能够承受高负载的力和扭矩, 3. 在滚珠丝杠上安装旋转方向指示器,滚珠丝杠卷数多的主要原因可能是以下几个方面： 1. 加工精度不足：如果加工过程中的刀具刃口磨损或加工参数设置不当，会导致零件尺寸偏差增大，从而导致丝杠卷数增多
