Abstract
The invention relates to a bearing sealing structure, comprising a shaft, a static ring, a moving ring, an oil seal, a bearing pedestal, an oil filler pipe, and an oil filling pump. The static ring is fixed on the shaft by a fastener. The moving ring is fixed on the bearing pedestal by a fastener. The static ring, the moving ring, and the bearing pedestal are designed with labyrinth slots. The labyrinth slots of the static ring, the moving ring, and the bearing pedestal form a labyrinth. The oil seal is arranged in an oil seal cavity formed by the bearing pedestal and the shaft. The shaft, the static ring, the oil seal, and the bearing pedestal form a fat storing cavity. The fat storing cavity is communicated with the labyrinth. The fat storing cavity is communicated with the oil seal cavity. The oil filler pipe is arranged in a non-rotating component, one end is connected with the fat storing cavity, and the other end is connected with the oil filling pump. The oil seal, the bidirectional labyrinth, and oil filling are used to seal a bearing, and oiling is performed on the bearing at regular intervals. The bearing sealing structure solves problems that contact of a self-aligning bearing oil seal and the shaft is not in place, and sealing is not good caused by corrosion of minerals on sealing elements. The bearing sealing structure is effectively forever, and maintenance cost is zero.

Described oil filler pipe (6) is arranged in on-rotatably moving part, and one end connects grease storing chamber, and the other end connects filling pump (7).
In an embodiment wherein, fitting surface, the rotating ring (3) of described stationary ring (2) and axle (1) are provided with sealer with bearing support (5) fitting surface, and described fastening piece is screw.
In an embodiment wherein, described filling pump (7) is manual filling pump.
In an embodiment wherein, described labyrinth is divided into axial and radial both direction.
In an embodiment wherein, described on-rotatably moving part is axle (1) rotary component is bearing support (5), and described oil filler pipe (6) is arranged in axle (1).
In an embodiment wherein, described on-rotatably moving part is bearing support (5) rotary component is axle (1), and described oil filler pipe (6) is arranged in bearing support (5).
Advantage of the present invention and beneficial effect:
Adopt oil sealing, two-way labyrinth and grease-filled to bearing seal, regularly carry out oiling with filling pump, selfaligning bearing oil sealing can be solved and corrode the problems such as the poor sealing brought with the tactile and Mineral pairs Sealing of being coupling, and forever effectively, without maintenance cost.
