摘　　要：标准件生产企业缺少对弹性挡圈装配过程中断裂的根本原因的分析和认识。本文结合装配过程中多次存在的此类问题,以分析弹性挡圈装配断裂的原因为研究课题。进行充分的原因分析,发现导致断裂的原因有模具因素和毛刺的因素。对影响因素做对比试验,通过压力机得出不同的推入力值,发现毛刺、缺口裂纹是影响装配过程中断裂的重要因素,并提出模具预防、减小毛刺的方案,可以避免断裂的现象。Standard parts production enterprises lack of analysis and understanding of the root causes of fracture in the assembly process of elastic ring. In this paper, the reasons for the fracture of the elastic retaining ring assembly are analyzed. Carry on the sufficient cause analysis, find that the cause of fracture is mold factor and burr factor. The influence factors are compared and tested. Different push force values are obtained by press. It is found that burr and notch crack are important factors affecting fracture in assembly process, and the scheme of preventing and reducing burr reduction of burr can avoid the phenomenon of fracture.
