该产品具有精度高、运动平稳、负载能力强等优点，广泛应用于各种机械设备领域,常用的滚珠丝杠尺寸有6mm、8mm、10mm、12mm、16mm、20mm等, 5.在滚珠丝杠两端加入保持架，确保其能够紧密固定住滚珠，并且在运动时不会出现滑动或旋转, 5. 低摩擦：滚珠丝杠副在运行过程中摩擦小，可降低磨损和能量损失,它的优点是具有高精度、高速度、高效率、低噪音、长寿命等特点，能够提高机械传动的精度和效率，提高生产效率和产品质量,同时，滚珠的滚动还会产生周向展开力，这个力的大小与滚珠的半径和滚道的曲率半径有关, 关键词：滚珠丝杠；上下移动；动态特性；安全性能；故障分析 Abstract: Ball screw is a widely used transmission component in the field of industrial automation, which has the advantages of high efficiency, reliability, and high accuracy. 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,燕尾槽导轨的制造工艺比较简单，生产成本较低，但精度和稳定性方面相对较差, 7. 调整滚珠丝杠和螺母的位置，确保其正常运转,其主要作用是将旋转运动转化为直线运动，并且具有高精度、高效率、长寿命等优点
