摘　　要：逆螺旋装置是一种具有广泛应用前景的新型传动机构。为避免在传动过程中钢球之间相互挤压和碰撞,在螺旋轴上常采用曲面凹坑与钢球配合的方式传动,但这给加工制造带来不便。以逆螺旋传动机构中的螺旋轴为研究对象,提出对其采用四轴联动数控加工方法加工,并通过VER ICUT软件进行加工仿真验证,实践证明该方法具有低耗、高效的优点,值得推广。Reversing Ball Screw Mechanism（RBSM） is a very promising new type of transmission mechanism.In order to avoid extrusion and collision during transmission,the match method between the pits of curved surface and the still ball which leads to some inconvenience of processing and manufacturing is often used.Describes the four-axis CNC machining methods of the screw axis in the Reversing Ball Screw Mechanism（RBSM）,and verifies the result by using VERICUT software,which shows this method having advantages of low cost and high efficiency.
