Abstract
The invention discloses a bearing sealing device. The bearing sealing device comprises a transmission shaft, bearings, a bearing cap and a cover plate. The transmission shaft is installed in the bearings and the bearing cap. An oil baffle disc is arranged between the bearing cap and the transmission shaft. A seal ring is arranged between the bearing cap and the oil baffle disc. The bearing cap is installed in the cover plate, and the bearings cooperate with the cover plate to fix the oil baffle disc. A seal pad is arranged at the position where the cover plate is matched with the bearing cap. An oil collection groove is formed in the middle of the oil baffle disc. An oil guide hole is formed in the oil collection groove. The oil guide hole is arranged to be a triangular oil collection port in the oil collection groove, and the other end of the oil guide hole is communicated with the seal ring and the bearing cap. According to the bearing sealing device, redundant lubricating oil in the transmission shaft is collected through the oil collection groove and the oil collection port, so that the oil inlet amount of the cover plate is reduced, oil pressure is reduced, the sealing effect is improved, and the bearing effect on the bearings is guaranteed.
