摘要

滚珠与返向器的撞击不仅是滚珠丝杠副产生低频噪声的主要原因，也是影响滚珠丝杠副寿命的主要因素。为了减少滚珠冲击对滚珠丝杠副性能的有害影响，文章首先建立了滚珠与返向器的碰撞接触模型，提出了滚珠在返向器内循环流畅性的评价指标，并提出了一种双圆弧滚道型线和优化设计方法。利用多体动力学仿真软件ADAMS对滚珠运行状态进行了仿真，仿真结果表明优化后的返向器滚道使得滚珠与返向器之间的碰撞接触力显著低，同时使得滚珠在返向器中循环流畅性更好。将双圆弧滚道型线和优化方法应用于滚珠丝杠副的滚珠返向器滚道型线的设计，具有实际工程意义

Abstract

The contact-impacts between balls and the ball-returner in running process causes the noise of the ball screw mechanism, and it lead to decrease of the service life of the ball screw mechanism. In order to solve this problem, the contact-impact dynamic model between ball and the returner is proposed, and a new evaluation index of recirculation fluency of ball-chain in ball returner is introduced. Based on this analysis, a new double arc profile of ball is presented, and the optimums of the geometric parameters are obtained based on genetic algorithm. The results proved that the optimal solution can not only decrease the contact-impact force between balls and returner but also make the recirculation of the ball-chain smoother. The double arc profile of the ball-returner and optimum method can be applied to the design of other types of ball returner.
