The end face spline hub bearing comprises a flange inner ring, a small inner ring and an outer ring, the small inner ring is arranged on the outer side of the flange inner ring in a sleeving mode, the flange inner ring is provided with a retaining wall and an outer flange used for being limited with the small inner ring, a rolling assembly is arranged between the retaining wall and the outer flange, and a sealing assembly is arranged between the small inner ring and the outer ring. The outer side of the small inner ring is provided with a sealing matching surface, and the axial outer end of the outer flange is provided with an end face spline. A cylindrical protection element is fixedly installed at the axial outer end of the small inner ring, covers the outer flange and at least covers the end face spline meshing position. The axial outer end of the small inner ring is provided with a first matching surface, a second matching surface and a third matching surface, the first matching surface is in riveting fit with the outer flange, the second matching surface axially abuts against the protection element for limiting, and the third matching surface is in radial pressing contact with the inner side of the protection element. The radial outer side of the outer flange and the protective element are spaced to form an annular gap, and the inner and outer peripheral walls are respectively provided by the two. The end face spline hub bearing is provided with the protection element, foreign matter can be prevented from entering the bearing, the structure is simple, and machining, manufacturing and assembling are convenient.

    本发明公开了一种端面花键轮毂轴承,包含法兰内圈、小内圈、外圈,小内圈套在法兰内圈外侧,法兰内圈有挡壁和外翻边用于与小内圈限位,它们之间有滚动组件,小内圈和外圈间有密封组件。小内圈外侧有密封配合面,外翻边轴向外端有端面花键。小内圈轴向外端固定安装筒状保护元件,罩住外翻边且至少覆盖端面花键啮合处。小内圈轴向外端有第一、第二配合面和第三配合面,第一配合面与外翻边铆压配合,第二配合面与保护元件轴向抵接限位,第三配合面与保护元件内侧径向压紧接触。外翻边径向外侧和保护元件间隔形成环形间隙,由两者分别提供内外周壁。本发明的端面花键轮毂轴承具有保护元件,能阻挡异物进入,结构简单,便于加工制造和装配。
