Description
Technical Field
The invention relates to the technical field of mechanical sealing, in particular to a sealed bearing box used under a spraying working condition.
Background
The bearing housing is a housing part that acts to support and lubricate the bearings, while also withstanding the axial and radial forces generated by the apparatus during operation. In devices having a shaft or roller, the shaft and roller are typically supported for rotation by bearings which are mounted in a bearing housing that is filled with lubricating oil. In the working process, the lubricating oil lubricates the bearing and the internal gear, so that the tightness of the bearing box needs to be fully ensured.
The bearing housing is typically sealed in two ways, an oil seal and a labyrinth seal. However, these two sealing methods are not ideal for bearing boxes, gear boxes or speed reducers which are located in the injection range of cooling media (such as emulsion, rolling oil, water, etc.) such as rolling mills and cleaning devices. Because the corrosiveness of the cooling medium is strong, the oil seal is easy to age, and the service life is short. The labyrinth seal sealing mode has higher precision requirements on processing and assembly, and the working environment on site is generally severe, the vibration is serious, the labyrinth seal is easy to wear, and the sealing effect of the labyrinth seal is further reduced. The bearing box can not be fully sealed and protected by the oil seal and the labyrinth seal, and cooling medium easily enters the bearing box body, so that the performance of lubricating oil is reduced, and the gear and the bearing are lack of lubrication or poor in lubrication, so that the service lives of the gear and the bearing are shortened, parts are required to be frequently replaced in the subsequent use process, and the operation efficiency of equipment is severely restricted.
Therefore, there is an urgent need for a bearing housing that has good sealability, long service life, and is less affected by environmental factors.
