实体双半保持架轴承电铆合工艺改进

Improvement on Process Technology of Electric Riveting for Solid Double-Half Cage

介绍航空传动系统球轴承用实体双半保持架装配铆合的难点,分析传统单面电铆装配工艺存在的问题,通过胎具的改进设计和铆合工艺流程的优化,实现了保持架的双面电铆合,铆合后铆钉头与保持架端面贴合紧密,铆钉抗断裂能力明显增强,提高了轴承的装配质量。

The difficuhies in assembling riveting of solid double - half cage assembly for ball bearing of air drive system are introduced. The problems of traditional single - sided electric riveting assembly process are analyzed. By improving the design of the mould and optimization of the riveting process, Riveting, rivet head and the end of the cage close fit, anti - riveting ability to significantly enhance the fracture and improve the quality of the bearing assembly.
