摘　　要：介绍轮毂轴承密封结构与主要结构参数,以第3代轮毂轴承单元密封结构为例,讨论了密封失效诊断、磨痕分析、残余过盈量获取与磨耗重构方法,并总结了密封失效的8类原因,为轮毂轴承的密封设计与失效分析提供了参考。The seal structural and main parameters of hub bearing are introduced. Taking the seal structure oI third gen- eration hub bearing unit as an example, the methods are discussed for seal failure diagnosis, grinding crack analysis, re- sidual interference acquisition and abrasion reconsitution. The eight reasons are summarized for seal failure, which pro- vide a reference for seal design and failure analysis of hub bearing.
