Description
Technical Field
The utility model belongs to the technical field of a sealing member, especially, relate to a standard sealing member for mechanical equipment.
Background
Axial oil leakage from fluid lubrication of sliding bearings in mechanical equipment has been a difficult problem to overcome. The existing oil seals generally adopt a check ring structure, and the structure utilizes the check ring contacted with a shaft to block oil so as to prevent the oil from leaking out along the direction of the shaft. The oil retaining effect of such a retainer ring structure depends on the tightness between the retainer ring and the shaft. When the sealing is good, the oil blocking effect is good, but the friction between the rotating shaft and the check ring causes the check ring to be worn, so that the clearance is increased, and the sealing effect is greatly reduced. In addition, for mechanical devices where positive pressure exists inside, the pressure and centrifugal forces generated when the shaft rotates may squeeze out the lubricant, thereby causing seal failure.
