弹簧卡环解锁力影响因素及控制方法

Spring Ring Unlocking Force Influencing Factors and Control Methods

摘要: 多批次弹簧卡环在预压解锁试验中出现解锁力大比例不合格问题，严重影响生产进度。通过分析弹簧卡环各生产环节，找出影响零件解锁性能的关键过程和控制方法。研究结果表明：热处理过程影响零件内部组织的一致性，进而影响弹簧卡环内应力，最终影响弹簧卡环解锁力，适当提高热处理回火时间可以降低预压解锁力；弹簧卡环解锁磨合面的粗糙度对解锁力较大。

Abstract: The large batch of spring rings has a large proportion of unlocking force unqualified problems in the pre-compression unlocking test, which seriously affects production progress. Through the analysis of each production link of the spring ring, the key processes and control methods that affect the unlocking performance of the parts are found out. The results show that the heat treatment process affects the uniformity of the internal structure of the parts, and then affects the internal stress of the spring ring, and finally affects the unlock force of the spring ring. Appropriately increasing the heat treatment tempering time can reduce the pre-compression unlocking force; the roughness of the unlocking friction surface the spring ring has a greater effect on the unlocking force.
