Firstly, the basic principle and classification of the lifting machine are introduced, and then the structure and working principle of the ball screw lifting mechanism are introduced in detail, including the ball screw, guide rail, motor and other components. Then, the performance of the ball screw lifting mechanism is analyzed and evaluated, mainly including transmission efficiency, load capacity, dynamic response and other aspects. Finally, the advantages and disadvantages of the ball screw lifting mechanism are discussed, and some improvement measures and application prospects are put forward. Keywords: ball screw; lifting machine; transmission efficiency; load capacity; dynamic response,例如，如果滚珠丝杠在多次定位中的偏差值变化范围为0.005mm，则说明它的重复精度为0.005mm, 2. 价格高：外循环滚珠丝杠的价格相对较高，因为它具有高精度、高刚性和长寿命等优点,FC滚珠丝杠是一种标准的螺纹连接件，在国际上被广泛使用, 8. 完成以上步骤后，可以进行测试和校准，调整参数，使机床运行更加稳定和精准, 这种循环形式可以保证滚珠丝杠的高精度和高效率，使其在工业生产中得到广泛应用,滚道形面的设计和制造需要非常高的精度和技术水平，以确保其质量和性能,修复方法包括磨削、喷涂、镀铬等,通过调整齿轮之间的间隙，可以调整齿轮之间的传动比例，从而实现精确的位置控制和速度控制, 2. 观察滚珠丝杠的标志：有些滚珠丝杠会在其表面上标注方向标志，通常是一个箭头或者字母
