Oil Seal Isuzu Oil Seal For Truck

Sealing principle and application of skeleton Oil Seal Isuzu Oil Seal For Truck

The skeleton oil seal is divided into three parts: self-tightening spring, sealing body, and reinforced skeleton.

The sealing principle of the skeleton Oil Seal Isuzu Oil Seal For Truck: Since there is an oil film controlled by the oil seal edge between the oil seal and the shaft, this oil film has fluid lubrication properties.

Analysis of the sealing principle Oil Seal Isuzu Oil Seal For Truck: Under the action of the skeleton oil seal, the stiffness of the oil film is just enough to form a crescent surface at the contact end of the oil film and the air, preventing the leakage of the working medium, thereby realizing the sealing of the rotating shaft. The sealing ability of the oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal will leak; if the thickness is too small, dry friction may occur, causing wear of the oil seal and the shaft; if there is no oil film between the sealing lip and the shaft, it will easily cause heat and wear. . Therefore, during installation, you must apply some oil on the sealing ring and ensure that the skeleton oil seal is perpendicular to the axis center line. If it is not perpendicular, the sealing lip of the oil seal will drain the lubricating oil from the shaft, which will also cause excessive sealing lip wear and tear. During operation, the lubricant in the housing leaks out slightly to form on the sealing surface.
