AXLE SEAL

摘要

An axle seal used to prevent lubricant from leaking between a rotating shaft and a shaft bore, for example, sealed fittings between the rotating shaft and shaft bore where static misalignment and/or dynamic misalignment exceeds conventional extent. 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.

1. An axle seal between a rotating shaft and a shaft bore, wherein the axle seal is used to prevent lubricant from leaking between the rotating shaft and the shaft bore, the seal includes:
a peripheral connection section adapted to be reliably connected to an inner edge of the shaft bore; an extensible and retractable adjustment section connected to the peripheral connection section and which allows the axle seal to make extension and retraction adjustments in a radial direction; a sealed contact section connected to an inner edge of the extensible and retractable adjustment section and adapted to be in sealed contact with a surface of the rotating shaft; and an alignment follower adapted to synchronously transfer a radial movement of the rotating shaft to the inner edge of the extensible and retractable adjustment section.
