深沟球轴承保持架铆合方法的优化

Optimization of Riveting Method for Cages of Deep Groove Ball Bearings

针对深沟球轴承保持架铆钉铆合后出现铆钉头断裂、脱落的问题,提出采用双面热铆合方法对保持架进行铆合。具体方法为:采用无钉头铆钉和双工装进行铆合,设计专用工装保证铆合前铆钉在保持架两端面凸出高度一致,在此基础上进行第一面铆合,完成一面铆合后,翻面选用原铆合胎具进行第二面铆合。试验证明该铆合方法合理可行。

Aimed at fracture and spalling of rivet head after riveting of cages for deep groove ball bearings,the double-sided hot riveting method is proposed to riveting of cages.The specific method is as follows:the rivet without rivet head and double tooling are used to riveting,the special tooling is designed to ensure same protrusion height of rivet at both ends of cages before riveting.Based on this,the original riveting mould is used to riveting of the second side after riveting of the first side.The rest proves that the riveting method is reasonable and feasible.
