联巨滚珠丝杠广泛应用于机床、自动化设备、航空航天、汽车工业、半导体设备等领域, 6. 控制方式：根据使用场景和需要升降的控制方式来选择合适的控制方式，比如手动或自动控制, 4. 设计更合理的结构：改进滚珠丝杠的结构设计，增加支撑点，减少变形，提高抗扭强度,具体来说，当滚珠在丝杠上滚动时，它们会与丝杠表面产生摩擦力，从而产生噪声, 6.选择预紧方式：预紧方式分为外置式和内置式，根据实际需要选择, 2. 焊接连接：将丝杠滚珠和轴通过高温的焊接方式连接起来, 6. 慢慢提升起重设备，将滚珠丝杠吊起，并将其放置在合适的位置上, 关键词：滚珠丝杠；润滑故障；产生机理；影响因素；解决方法 Abstract: Ball screw is a very important mechanical transmission component, which is widely used in various mechanical equipment. However, in the long-term operation, ball screw is prone to lubrication failure, resulting in unstable operation and even unable to work properly. In this paper, the working principle of ball screw is analyzed, the mechanism and influencing factors of lubrication failure are studied, and corresponding solutions are proposed. The experimental results show that, by correctly selecting lubricants, maintaining the integrity of the lubricating film and regularly carrying out maintenance, etc., the lubrication failure of ball screw can be effectively prevented and solved. Keywords: Ball screw; Lubrication failure; Mechanism; Influencing factors; Solutions.,选择“Smart Dimension”工具，定义圆的直径, （3） 精度：根据应用要求选择具有高精度的滚珠丝杠
