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,如果松动，需要固定螺母, 3. 检查轴向游动：用游标卡尺或者测微卡尺对滚珠丝杠进行轴向游动的测量，看是否在规定的误差范围内,更换滚珠丝杠丝母的具体步骤如下： 1. 将滚珠丝杠的电源关闭，并移除电源插头,滚珠丝杠提供线性运动，伺服电机则提供精准的控制力和速度, 首先，滚珠丝杠的优点之一是高精度,滚珠丝杠轴承具有承载能力大、精度高、摩擦小、转速高等优点,为了安装滚珠丝杠，需要在机械零件中铣出适合滚珠丝杠的孔，这就是铣床滚珠丝杠大孔的作用,形螺帽 滚珠丝杠螺帽通常采用方形设计，以便更容易使用工具进行紧固和松开
