This paper mainly studies the problem of up and down movement of ball screws. By establishing kinematic and dynamic models, the dynamic characteristics of ball screws in the process of up and down movement are analyzed. At the same time, for common fault situations in practical applications, such as overload and overspeed, the safety performance of ball screws is evaluated, and corresponding solutions are proposed to ensure their reliability and stability in industrial production. Keywords: ball screw; up and down movement; dynamic characteristics; safety performance; fault analysis, 7. 品牌推荐：国内外知名品牌如THK、HIWIN、NSK、SKF、FAG等都提供高品质的滚珠丝杠副产品,丝杆副的优点是结构简单，价格便宜，但是摩擦力大，效率低,研磨滚珠丝杠是一种通过滚珠的滚动来实现传递动力和转动的机械装置, 5. 使用螺丝刀将小型滚珠丝杠固定在安装座上，注意螺丝的紧固度，以免影响设备的使用,如果传动间隙不被消除，会导致滚珠丝杠的运动不稳定，影响到机器人、数控机床等高精度设备的精度和稳定性, 2. 滚珠丝杠计算：计算滚珠丝杠的承载能力、寿命、刚度、摩擦力等参数,如果是，需要重新紧固或更换
