ABSTRACT:
A seal between a housing and a shaft is formed of two ring members interlocked together. The two ring members include a rotor and a stator which are interlocked so as to provide a labyrinth passageway for preventing contaminants from reaching a rotating shaft. The stator includes a main portion, which functions to direct fluid from the rotating shaft back into a housing, and a cover portion which covers the rotor, cooperates with the rotor to provide the labyrinth passageway, and includes all opening for directing the contaminants out of the seal. The stator main portion includes a plurality of annular ridges and grooves and an axial groove. The stator cover portion includes an annular recess, which receives an annular protrusion of the rotor. The stator main portion is located axially adjacent to the rotor, while the cover portion is located radially adjacent to the rotor.
