摘　　要：针对限制滚珠螺旋副高速运转的滚珠滑移及自锁现象,建立滚珠螺旋副的三维实体模型,并对滚珠运动特性进行理论计算和分析,揭示出滚珠螺旋副中滚珠滑移和自锁效应产生的原因以及对滚珠螺旋副高速性能的影响。以滚珠运动规律为基础,推导滚珠滑移速度公式,提出如何避免滚珠卡死及减小滑移以提高滚珠螺旋副高速性能的方法。并用ADAMS软件对其进行了动力学仿真分析,仿真结果证实了所推导滚珠运动规律的正确性。In view of self-locking and slipping phenomenon on restricting high-speed operation of ball screw,the model of ball screw is constructed and theoretical analysis of the movement feature of ball screw is made to reveal the reason of self-locking and slipping,and its influence on high-speed operation. Then the sliding speed format of ball screw is derived according to the movement rules of ball screw,and effective methods to avoid ball self-locking and slipping are put forward. Dynamics analysis is conducted with ADAMS software. Simulation results have confirmed the correctness of ball screw＇ movement.
