  • Patent number: 5667225
    Abstract: A shaft seal includes a plurality of axially spaced annular sealing rings which define oil collection channels. A radial drain aperture extends from the bottom of each channel into an interior trough which extends axially to a discharge orifice in a front end wall of the seal. The bottom of the trough is downwardly inclined for enhanced gravity flow. A portion of the outer periphery of the seal which projects into the housing is outwardly flared and includes a lower discharge lip to provide a return flow surface which directs return flow of sprayed oil away from the seal.
