FLOODED BEARING ISOLATOR

摘要

A labyrinth sealing device is disclosed for use between a rotating shaft and a bearing housing, hi some embodiments;, an internal stator engages the housing and a rotor engages the shaft. A labyrinth pathway is defined between the rotor and stator to prevent the migration of lubricants and/or contaminatnts in either direction. The rotor acts as a running surface for the sealing element, but may also with a ground surface of the rotor to provide a pump that continuously draws lubricant away from the sealing Mp toward a sump. In another embodiment, the stator and sealing element are combined as a sealing element formed from a sealing material. A recess in the sealing lip creates a pressure differential at the sealing surface and minimizes wear.
