Firstly, the structure and working principle of ball screw are introduced, and then the load and transmission characteristics of ball screw are analyzed. In view of the calculation problem of ball screw, a calculation method based on finite element analysis is proposed. By establishing the finite element model of ball screw and analyzing its mechanics, the stress and deformation of ball screw are obtained. Then, according to the calculation results, the design parameters of ball screw are determined, including the diameter of screw, pitch, diameter of ball, number of ball, etc. Finally, the correctness of the calculation results is verified by experiment.
