摘　　要：滚珠丝杠零件的选配必须依据最优接触角理论,即使装配后的滚珠丝杠副内的滚珠与滚道的接触角达到最优值。目前的接触角计算模型限定条件太窄,且需要试算方法,计算量大且计算效率低,针对这一问题,结合实际的滚珠丝杠副装配工艺,考虑滚珠丝杠副滚道的截型磨削误差等因素,基于通用的滚珠丝杠副弹性接触角的计算模型,使用MATLAB GUI设计了滚珠丝杠副辅助装配软件,能够根据不同的装配方式及所提供的参数给出选配后滚珠丝杠副的弹性接触角值,并直接选配相应的丝杠、螺母或滚珠,极大地提高了滚珠丝杠副的装配精确度和效率。The selection of ball screw must be based on the optimal contact angle theory,which means the contact angle between the ball and raceway of the ball screw pair must be the optimum value.Using contact angle calculation model to calculate the contact angle,trial balance is needed to obtain the optimal contact angle,which brings about a large amount of calculation and low efficiency.To solve the problem,a ball screw auxiliary assembly software was designed by MATLAB GUI module,which combined the assembly process of ball screw,considered the grinding error and other factors of raceway of ball screw,based on the general model for calculating the elastic contact angle of ball screw pair.The software can provide the actual processing results of different parts and the optimal elastic contact angle of ball screw.
