The invention provides a bearing sealing structure, which relates to the technical field of bearings, is hooped on a flange of a bearing inner ring, and comprises a support body, the outer framework is connected with the supporting body; the inner framework is connected with the supporting body, and the outer wall of the inner framework abuts against a flange on a bearing inner ring; the multiple sealing pieces are arranged on the supporting body and connected with the supporting body, and any sealing piece is matched with an annular groove in a flange of a bearing inner ring in an embedded mode; and the fastening piece is fastened on the supporting body and is arranged between the outer framework and the inner framework, so that the sealing piece is tightly attached to the annular groove and/or the sealing piece is tightly attached to a flange of a bearing inner ring. Three-layer sealing arrangement of the hub bearing can be achieved, lubricating liquid between the bearing outer ring and the bearing inner ring is prevented from flowing out, and the sealing performance of the hub bearing is improved.

    本发明提供一种轴承密封结构,涉及轴承技术领域,套箍在轴承内圈的挡边上,并包括:支撑体;外骨架,与所述支撑体连接;内骨架,与所述支撑体连接,且所述内骨架的外壁与轴承内圈上的挡边抵接;多个密封件,设置在所述支撑体上并与所述支撑体连接,任意一个所述密封件与轴承内圈的挡边上的环槽嵌设配合;紧固件,紧固在所述支撑体上,并置于所述外骨架和所述内骨架之间,实现所述密封件与所述环槽的紧密贴合和/或所述密封件与轴承内圈的挡边的紧密贴合。本发明可实现对轮毂轴承的三层密封设置,防止轴承外圈和轴承内圈之间的润滑液流出,提升对轮毂轴承的密封性能。
