Abstract
A rotating shaft assembly includes a housing that defines a bore that extends from an area exterior to the housing to an area interior to the housing. A shaft is rotatably disposed in the housing about an axis of the bore. The shaft extends through the bore between the interior and exterior areas. A lubricant retention area is axially outward of, and sealed from, the interior area. The retention is configured to collect lubricant from the interior area. A sump is in fluid communication with the interior area. A drain extends between the retention area and the sump. A check valve is disposed in the drain. The check valve is oriented to permit lubricant flow from the retention area to the sump and to prevent lubricant flow from the sump to the retention area.
