The invention relates to the technical field of sealing structures, and discloses a shaft body sealing structure which comprises a connecting part and a shaft body which are coaxially arranged. The shaft body is rotationally connected into the connecting part through a bearing. The shaft body sealing structure further comprises a sealing ring, a sealing sleeve and a blocking piece. Compared with the prior art, the sealing structure adopts a double-layer waterproof structure, the interior is sealed by the sealing ring, and the exterior is sealed by the sealing sleeve. Because of the double-layer protection structure, a double-layer protection effect is achieved, the waterproof and sealing effects are excellent, flowing water can be well prevented from entering the end of a turbine shaft, water is prevented from entering a motor from the end of the turbine shaft, the failure rate of the motor due to water is reduced, and the working reliability of a wiper motor in severe weather is improved. In addition, under auxiliary sealing of the blocking piece, water vapor can be prevented from entering the turbine shaft, and the overall sealing performance of the structure is further improved.

    本发明涉及密封结构技术领域,公开了一种轴体密封结构,包括同轴设置的连接部与轴体,所述轴体通过轴承转动连接于所述连接部内,还包括密封圈、密封套以及挡片。与现有技术相对比,本密封结构采用双层防水结构,内部采用密封圈密封,外部采用密封套密封。双层的保护结构,形成双层保护效果,具有优越的防水密封效果,能够很好地避免流水进入涡轮轴端部,避免水分从涡轮轴端部进入电机内部,降低电机进水故障率,提高雨刮电机在恶劣天气下工作的可靠性。另外,在挡片的辅助密封下,还能避免水汽进入涡轮轴,进一步提高本发明的整体密封性能。
