US Classification:
184 618, 277551, 277559
Abstract:
A shaft seal assembly for use with a reciprocating or rotating shaft includes a shaft seal, a lubricant-storing ring, and a retainer. The retainer and ring can be formed as a subassembly and then combined with a shaft seal. The seal includes an annular body portion, a first sealing lip portion, and a first pocket portion. The first sealing lip portion has a substantially uniform axial dimension and is adapted to sealingly engage a shaft. The first pocket portion includes a plurality of pockets, each having an opening toward the first sealing lip portion. The plurality of pockets are each adapted to collect a working fluid when the shaft axially displaces in a first direction and to dispense the working fluid when the shaft axially displaces in a second direction. The assembly provides a lubricated shaft and seal that improves the effective life of the shaft seal.
