Firstly, the basic structure and working principle of ball screw are introduced. Then, the factors involved in low-speed ball screw linear motion, such as friction force, rolling resistance, inertia force, etc., are analyzed, and the influence of these factors on ball screw linear motion is studied by using numerical simulation method. The research results show that friction force has the greatest influence on ball screw linear motion, followed by rolling resistance and inertia force. In order to reduce these influences, appropriate materials, lubrication methods and processing techniques should be used in the design and manufacturing process to improve the motion accuracy and service life of ball screw. Keywords: low-speed ball screw; linear motion; friction force; rolling resistance; inertia force; numerical simulation., 6. 安装滚珠丝杠：将滚珠丝杠安装到螺母内部，确保其正常运行, 2. 转速：滚珠丝杠的选型要考虑其所需的最大转速，以满足应用要求,导轨则是用于支撑和引导运动轴的线性运动装置，具有高精度、高刚性等特点,滚珠丝杠所受的力矩可以用以下公式计算： M = F x P 其中，M表示力矩，单位为牛顿·米（N·m）；F表示作用在滚珠丝杠上的力，单位为牛顿（N）；P表示力臂的长度，即作用力的垂直距离到轴线的距离，单位为米（m）, 5. 最后，确保调节螺钉已经紧固，并且螺母和滚珠丝杠能够顺畅地旋转，而不会出现任何卡顿或摩擦, 9. 最后，在轴心和导向块之间画出一条直线，代表滚珠丝杠的结构, 4. 使用扳手将滚珠丝杠和锯条夹紧，确保滚珠丝杠稳固
