Abstract
A seal cartridge adapted to be mounted upon a rotating shaft, including a rotor and a stator, the rotor and stator being arranged to create a labyrinth portion and a contact portion. The rotor includes a radially outwardly directed surface and the stator includes one or more flanges biased toward the rotor surface to create the contact portion. The rotor and stator create a labyrinth portion with an inwardly facing ridge positioned within an outwardly facing groove. The stator may include a shoulder for positioning the seal cartridge with respect to a housing, or instead a sloped surface. The rotor may also have a flange which deforms and fits within an annular notch of the stator.
Claims44
A two-piece, interlocked seal device adapted to be mounted upon a rotatable shaft, said seal device comprising:
- a rotor having a flange, a radially outwardly directed groove, and a radially outwardly directed surface;
- and
- a stator having a cover with an annular notch and a radial opening adapted to direct contaminants from the seal, a radially inwardly directed ridge, and at least one flange biased toward said rotor surface;
- wherein said stator ridge is positioned within said rotor groove and said rotor flange is positioned within said stator annular notch to create a labyrinth portion and said stator flange and said rotor surface create a contact portion.
A two-piece, interlocked seal device adapted to be mounted upon a rotatable shaft, said seal device comprising:
- a rotor having a flange, a radially outwardly directed groove, and a radially outwardly directed surface;
- and
- a stator having a cover with an annular notch and a radial opening adapted to direct contaminants from the seal, a radially inwardly directed ridge including an inclined surface, and a plurality of flanges biased toward said rotor surface;
- wherein said stator ridge is positioned within said rotor groove and said rotor flange is positioned within said stator annular notch to create a labyrinth portion and said stator flanges and said rotor surface create a contact portion.
A sealed system including a housing, a rotatable shaft and a two-piece seal device, said seal device comprising:
- a rotor having a flange, a radially outwardly directed groove, and a radially outwardly directed surface;
- and
- a stator having a cover with an annular notch and a radial opening adapted to direct contaminants from the seal, a radially inwardly directed ridge, and at least one flange biased toward said rotor surface;
- wherein said stator ridge is positioned within said rotor groove and said rotor flange is positioned within said stator annular notch to create a labyrinth portion and said stator flange and said rotor surface create a contact portion.
A sealed system including a housing, a rotatable shaft and a two-piece seal device, said seal device comprising:
- a rotor having a flange, a radially outwardly directed groove, and a radially outwardly directed surface;
- and
- a stator having a cover with an annular notch and a radial opening adapted to direct contaminants from the seal, a radially inwardly directed ridge including an inclined surface, and a plurality of flanges biased toward said rotor surface;
- wherein said stator ridge is positioned within said rotor groove and said rotor flange is positioned within said stator annular notch to create a labyrinth portion and said stator flanges and said rotor surface create a contact portion.
