ABSTRACT:
An improved seal is provided to minimize or eliminate lubricant migration and welling problems on electric motors, gear boxes, and lubricant contamination in rolling mills. The improved seal includes a stator ring fixed in the housing and a rotor ring sealingly mounted on the shaft for rotation therewith. A second, captured, rotor is provided within the stator ring and is sealingly mounted upon the shaft for rotation therewith. The captured rotor includes a plurality of radially extending slots which impart increased energy to migrating and welling lubricant so as to force the lubricant into a communicating annular groove within the stator, which in turn is in communication with a return trough which directs the energized lubricant back into the housing or, in the case of rolling mills, of contamination back to the exterior.
