TC- double lip skeleton oil seal seal

1. Since there is an oil film controlled by the edge of the oil seal between the skeleton oil seal and the shaft, this oil film has fluid lubrication characteristics. Under the action of the surface tension of the liquid, the rigidity of the oil film just makes the contact end of the oil film and the air form a crescent surface, which prevents the leakage of the working medium and realizes the sealing of the rotating shaft.The sealing ability of the skeleton oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too large, the oil seal leaks. If the thickness is too small, dry friction may occur, causing the skeleton oil seal and shaft to wear. If there is no oil film between the sealing lip and the shaft, it is easy to cause heat. , Wear.

2.During installation, some oil must be applied to the sealing ring while ensuring that the skeleton oil seal is perpendicular to the axis of the shaft. If it is not perpendicular, the sealing lip of the skeleton oil seal will drain the lubricant from the shaft and cause excessive wear of the sealing lip. During operation, the lubricant in the housing slightly seeps out to achieve the ideal state of forming an oil film on the sealing surface.
