Background

The skeleton oil blanket is the most commonly used seal type in the oil blanket, and skeleton oil blanket structure has three parts to constitute: the oil seal comprises an oil seal body, a reinforcing framework and a self-tightening spiral spring. The single-lip framework oil seal and the double-lip framework oil seal can be separated according to the structural form. The framework oil seal has the function of isolating the parts to be lubricated in the transmission parts from the output parts so as to prevent lubricating oil from leaking; typically, before use, the lip inner diameter of the oil seal is smaller than the shaft diameter, with some interference. After the oil seal is installed, certain radial pressure can be generated on the rotating shaft due to the interference of the lip and the shrinkage of the self-tightening spring. Meanwhile, under the action of the clasping force generated by the shrinkage of the spring, the oil seal can overcome the gap generated by the vibration, the movement and the jumping of the shaft in the rotating state, so that the lip of the oil seal can be tightly attached to the surface of the rotating shaft.
