摘要
Abstract
To avoid the return tube failure caused by collision and friction between recirculation ball and return tube in the internal recirculation ball screw,we optimized the existing ball-return curve of the return tube,aiming to reduce the collision force and friction torque between recirculation ball and return tube;we also optimized the ratio coefficient of the sine ball-return curve and the five parabolic ball-return curve.After obtaining the optimal ball-return curve,a 3D model was built and the simulation analysis based on the multi-body dynamics was further carried out.The analysis results show that the optimized ball-return curve of the return tube can effectively reduce the collision force and friction torque between recirculation ball and return tube,and that the ball-return smoothness and dynamic behavior of the recirculation ball screw were obviously improved.关键词
