The utility model discloses a waterproof shaft end sealing structure, and relates to the technical field of bearing sealing. The rotating shaft penetrates through one side of the shell and extends into the shell; the bearing is arranged at the end, located in the shell, of the rotating shaft. Wherein a labyrinth seal, a first oil seal, a grease cavity and a second oil seal are arranged in the shell, and the labyrinth seal, the first oil seal, the grease cavity and the second oil seal can prevent water from flowing to the bearing from the outside of the shell. The waterproof shaft end sealing structure is good in waterproof effect, and the situation that the bearing is damaged due to the fact that water flows to the bearing can be reduced. 本实用新型公开了一种防水轴端密封结构，涉及轴承密封技术领域，包括：壳体；转轴，所述转轴贯穿所述壳体的一侧伸至所述壳体内部；以及轴承，所述轴承设置在所述转轴位于所述壳体内部的一端；其中，所述壳体内部设置有迷宫密封、第一油封、油脂腔和第二油封，所述迷宫密封、第一油封、油脂腔和第二油封能够阻挡水从所述壳体外部流至所述轴承上。该防水轴端密封结构的防水效果好，能够减少因水流至轴承导致轴承损坏的情况发生。
