摘　　要：滚珠与反向器的碰撞与摩擦,是导致滚珠丝杠副摩擦力矩产生波动的一个重要原因,也是导致反向器失效的主要原因。因此需要对反向器回珠曲线进行优化,降低滚珠与反向器的碰撞力,提高反向器的流畅性。提出了一种新型多段圆弧端塞式反向器的设计思路与优化方法。采用Matlab进行有约束的非线性优化,得到优化后回珠曲线,得到优化后反向器的Pro/E三维模型,利用ADAMS仿真软件对优化前和优化后的反向器进行动力学分析,仿真结果表明优化后新型端塞式反向器能有效的降低滚珠与反向器的碰撞力,并使碰撞力更加均匀,有利于提高反向器的流畅性。Collision and friction between ball and the return tube is an important reason that generates ball screw friction torque fluctuation. It＇s also the the cause of return tube failure. So it needs to optimize the return tube curve to reduce collision force between ball and return tube, and improve the fluency of return tube. It puts forward a new design and optimization method of several circular arcs end plug type return tube. Using Matlab to have a constrained nonlinear optimization then get the optimized curve. Builds 3D model of the optimized return tube by Proe. Uses ADAMS simulation software to analyze the return tube dynamics both before and after the optimization. The results show that the new optimized end plug type return tube can effectively reduce the collisions force between ball and the return tube. The collision force is more uniform. It is benefit to the fluency of the return tube
