Claims
- 1. A damper comprising:
a first part having a base and a wall extending outwardly from said base and defining a space having an open end; a second part rotatably secured to said first part and closing said open end, said second part including a cover and a rim at the periphery thereof; one of said wall and said rim including a radially extending lip and the other of said wall and said rim defining a recess for receiving said lip and defining a continuous edge for engaging said lip; and damping fluid compressed in the space between said first and second parts and contained therein by a seal formed by said edge against said lip.
- 2. The damper of claim 1, said cover having a gear on an outer surface thereof.
- 3. The damper of claim 2, said cover extending into said space defined by said wall.
- 4. The damper of claim 3, said lip disposed at an outer edge of said wall.
- 5. The damper of claim 4, said base defining a groove outwardly of said wall, and said rim extending into said groove.
- 6. The damper of claim 5, said base defining a protrusion into the space defined by said wall, and said cover having a dome for receiving said protrusion.
- 7. The damper of claim 1, said cover extending into said space defined by said wall.
- 8. The damper of claim 7, said lip disposed at an outer edge of said wall.
- 9. The damper of claim 1, said lip disposed at an outer edge of said wall.
- 10. The damper of claim 1, said base defining a groove outwardly of said wall and said rim extending into said groove.
- 11. The damper of claim 1, said base defining a protrusion into said space defined by said wall, and said cover having a dome for receiving said protrusion.
- 12. A damper comprising:
a fixed first part and a rotatable second part secured to said first part; said first and second parts defining radially overlapping structures having substantially continuous circumferential engagement over a limited radial width when placed under axial force in opposite directions; and damping fluid under compression within a substantially continuous space between said first and second parts radially confined by said substantially continuous circumferential engagement.
- 13. The damper of claim 12, said first part including a base and a cylindrical wall, and said second part including a cover having a rim for engaging said wall and a gear integral with said cover.
- 14. The damper of claim 13, said wall having a radially outwardly directed lip and said rim having a thickened end radially overlapping said lip.
- 15. The damper of claim 14, one of said base and said cover having a protrusion and the other of said base and said cover having a dome for receiving said protrusion.
- 16. The damper of claim 15, said rim disposed outwardly of said wall.
- 17. A gear damper comprising:
a fixed first part; a second part rotatable relative to said first part, said second part having a cover, a gear integral with said cover and an outer rim; said first and second parts defining a continuous sliding seal of limited radial width; and a continuous layer of damping fluid contained between said first and second parts and radially constrained by said seal.
- 18. The gear damper of claim 17, said seal formed by axial separation of said first and second parts.
- 19. The gear damper of claim 18, said damping fluid being compressed between said first and second parts and apply force against said first and second parts for creating said seal.
- 20. The gear damper of claim 17, said damping fluid being compressed between said first and second parts and apply force against said first and second parts for creating said seal.
