摘　　要：反向器的优劣直接影响到滚珠丝杠副的使用性能,而回珠曲线是影响滚珠丝杠副性能的关键因素。文中通过对反向器进行力学分析,得出一种新型的滚珠丝杠副反向器的回珠曲线,并对此设计曲线在ADAMS中进行仿真分析,对比分析优化前后端塞式滚珠丝杠副反向器的运动情况,结果表明优化后的多段圆弧式反向器与滚珠的碰撞力明显减小,大大提高了滚珠丝杠副反向器的流畅性。Reversers quality directly affects the performance of ball screw pair,and the ball curve is the key factors that affect the performance of ball screw pair. This article analyzes the mechanics of the reverser and obtains a new type of ball curve of the ball screw pair of reverser. The simulation of the design curve is carried out using ADAMS to compare movement situation of end plug type ball screw pair of reverser before and after optimization, the results show that the optimized multistage arc reverser and ball collision force decreased greatly, the ball screw pair of reverser fluency is greatly improved.
