  • Shaft sealing assembly
    Patent number: 7498703
    Abstract: A shaft sealing assembly (10) for providing a seal between a shaft and a housing within which the shaft rotates. The sealing assembly (10) comprises a rotor (40) adapted to be mounted to the shaft and a stator (42) adapted to be mounted to the housing. The rotor (40) and the stator (42) include recesses and/or projections which mate and interlock to form a labyrinth lubricant chamber therebetween. The stator (42) carries at least one electrical-path-establishing element (88) which forms an electrically conductive path between the shaft and an electrical ground to thereby dissipate residual current and/or stray shaft voltage.
