Abstract
An axle seal used to prevent lubricant from leaking between a rotating shaft and a shaft bore. The seal includes: a peripheral connection section reliably connected to an inner edge of the shaft bore; an extensible and retractable adjustment section connected to the peripheral connection section, allowing the seal to make extension and retraction adjustment in a radial direction; and a sealed contact section connected to the inner edge of the extensible and retractable adjustment section and potentially in sealed contact with the surface of the rotating shaft. The seal contains an alignment follower that can synchronously transfer a radial movement of the rotating shaft to the inner edge of the extensible and retractable adjustment section. One application would be an oil seal between a front cover and crankshaft.
