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,选择滚珠丝杠支撑座时需要考虑以下几个因素： 1. 负载能力：根据工作负载的大小选择合适的滚珠丝杠支撑座,滚珠丝杠导轨需要定期加油以保持良好的润滑效果，延长使用寿命,但是，对于高精度的滚珠丝杠，导程的差异可能会更小，甚至可以达到0.001mm以下, 2. 将滚珠丝杠安装在固定座上，注意滚珠丝杠和固定座的接口要紧密贴合，不能有松动,一般来说，滚珠丝杠的精度较高，适合用于需要高精度、高速度、高重复性运动的场合, 2. 点标注法：在滚珠丝杠上标记一个或多个点，通常用于标记特定的位置或参考点, 2. 轴向受力分解 轴向受力分解是滚珠丝杠在轴线方向上的受力分解，主要包括以下两个方向的受力： （1）推力：指轴向方向的滚珠丝杠所能承受的最大推力,它们的外观通常是金属色的，没有特殊的装饰, 苏州冷轧滚珠丝杠维修需要具备一定的专业知识和技能，同时需要使用专业的工具和设备
