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.
