Claims
- 1. A two-piece interlocked labyrinth seal, comprising:
a rotor including an intermediate portion and an enclosure member surrounding a radial opening; and a stator including a main body portion, having a plurality of annular ridges, and a cover positioned within said radial opening, wherein said cover interlocks with said enclosure member, and wherein one of said annular ridges is adapted to restrict passage of air through the seal when the seal is mounted to a shaft.
- 2. The labyrinth seal of claim 1, wherein said stator comprises a flange which with said intermediate portion and said enclosure member encloses said cover within said radial opening.
- 3. The labyrinth seal of claim 1, wherein said stator comprises three annular ridges.
- 4. The labyrinth seal of claim 3, wherein two of said annular ridges extend a first distance and a third of said annular ridges extends a second distance, wherein said second distance is greater than said first distance.
- 5. The labyrinth seal of claim 4, wherein said third of said annular ridges inhibits passage of air through the seal when the seal is mounted to a shaft.
- 6. The labyrinth seal of claim 4, wherein one of said annular ridges includes an opening.
- 7. A two-piece interlocked labyrinth seal, comprising:
a rotor including an intermediate portion, an enclosure member and a flange surrounding a radial opening; and a stator including a main body portion, having a plurality of annular ridges, and a cover positioned within said radial opening, wherein said cover interlocks with said flange.
- 8. The labyrinth seal of claim 7, wherein said stator comprises a flange which with said intermediate portion, said enclosure member and said flange of said rotor encloses said cover within said radial opening.
- 9. The labyrinth seal of claim 7, wherein said stator comprises three annular ridges.
- 10. The labyrinth seal of claim 9, wherein two of said annular ridges extend a first distance and a third of said annular ridges extends a second distance, wherein said second distance is greater than said first distance and is sufficient to restrict passage of air through the seal.
- 11. The labyrinth seal of claim 10, wherein said third of said annular ridges inhibits passage of air through the seal when the seal is mounted to a shaft.
- 12. The labyrinth seal of claim 10, wherein one of said annular ridges includes an opening.
- 13. The labyrinth seal of claim 7, wherein said cover includes an interlocking portion which interlocks with said flange.
- 14. The labyrinth seal of claim 13, wherein a radial opening extends through said interlocking portion.
- 15. The labyrinth seal of claim 14, wherein said interlocking portion includes a plurality of radially outwardly extending flanges.
- 16. A sealed system, comprising:
a rotatable shaft; a housing; and a two-piece interlocked labyrinth seal mounted on said housing and around said shaft, said seal comprising:
a rotor including an intermediate portion and an enclosure member surrounding a radial opening; and a stator including a main body portion, having a plurality of annular ridges, and a cover positioned within said radial opening, wherein said cover interlocks with said enclosure member, and wherein one of said annular restricts passage of air between the seal and said rotatable shaft.
- 17. The sealed system of claim 16, wherein said stator comprises a flange which with said intermediate portion and said enclosure member encloses said cover within said radial opening.
- 18. The sealed system of claim 16, wherein said stator comprises three annular ridges.
- 19. The sealed system of claim 18, wherein two of said annular ridges extend a first distance and a third of said annular ridges extends a second distance, wherein said second distance is greater than said first distance.
- 20. The sealed system of claim 19, wherein said third of said annular ridges inhibits passage of air through the seal when the seal is mounted to a shaft.
- 21. The sealed system of claim 20, wherein said third annular ridge contacts said shaft when said seal is mounted on said housing and around said shaft.
- 22. The sealed system of claim 19, wherein one of said annular ridges includes an opening.
- 23. A sealed system, comprising:
a rotatable shaft; a housing; and a two-piece interlocked labyrinth seal mounted on said housing and around said shaft, said seal comprising:
a rotor including an intermediate portion, an enclosure member and a flange surrounding a radial opening; and a stator including a main body portion, having a plurality of annular ridges, and a cover positioned within said radial opening, wherein said cover interlocks with said flange.
- 24. The sealed system of claim 23, wherein said stator comprises a flange which with said intermediate portion and said enclosure member encloses said cover within said radial opening.
- 25. The sealed system of claim 23, wherein said stator comprises three annular ridges.
- 26. The sealed system of claim 25, wherein two of said annular ridges extend a first distance and a third of said annular ridges extends a second distance, wherein said second distance is greater than said first distance and is sufficient to restrict passage of air between the seal and the rotatable shaft.
- 27. The sealed system of claim 26, wherein said third of said annular ridges inhibits passage of air through the seal when the seal is mounted to a shaft.
- 28. The sealed system of claim 27, wherein said third annular ridge contacts said shaft when said seal is mounted on said housing and around said shaft.
- 29. The sealed system of claim 26, wherein one of said annular ridges includes an opening.
