Abstract

A bearing assembly with an anti-rotational device configured to prevent turning, unthreading, or loosening of a stationary tapered roller bearing outer race 10 having threaded outer surfaces 10a, 14a used for bearing adjustment, axial shaft retention, and axial thrust load transfer. The bearing assembly includes an annular ring 16 secured to, and extending radially outward from an axial face 18 of the bearing outer race 10. Following rotational adjustment and axial positioning of the bearing, the annular ring 16 is positively engaged by one or more attachment points 14 associated with a stationary housing 12, thereby securing the bearing outer race 10 against further axial and rotational movement.

Claims

AMENDED CLAIMS received by the International Bureau on 23. jan.2009 (23.01.2009)CLAIMS:
1. (Cancelled)
2. A bearing cup anti-rotation assembly for securing an externally threaded bearing cup in threaded engagement with an internally threaded housing boss of a stationary coaxial housing against axial and rotational movement relative to the stationary coaxial housing, comprising: an annular ring secured to an outer axial end face of the bearing cup, said annular ring having an outer circumference which is greater than an outer circumference of said bearing cup; a means for securing said annular ring to said housing boss in a fixed position relative to said stationary coaxial housing at any rotational position of said annular ring and said secured bearing cup; and wherein said means for securing includes at least one locking plate configured for attachment to said housing boss, said locking plate having a radially inward projecting protrusion adapted to engage a circumferential peripheral edge of said annular ring upon attachment of said locking plate to said housing boss.
3. The bearing cup anti-rotation assembly of Claim 2 wherein the shape of said protrusion is a radially-inwardly directed "V".
4. The bearing cup anti-rotation assembly of Claim 2 wherein said housing boss includes a slot, and said protrusion further engages said slot.
5. The bearing cup anti-rotation assembly of Claim 2 wherein said protrusion is configured to deform said circumferential peripheral edge of said annular ring upon engagement therewith.
6. The bearing cup anti-rotation assembly of Claim 2 wherein said circumferential peripheral edge of said annular ring includes a slot, and wherein said protrusion is configured to engage said slot.
7. A bearing cup anti-rotation assembly for securing an externally threaded bearing cup in threaded engagement with an internally threaded housing boss of a stationary coaxial housing against axial and rotational movement relative to the stationary coaxial housing, comprising: an annular ring secured to an outer axial end face of the bearing cup, said annular ring having an outer circumference which is greater than an outer circumference of said bearing cup; a means for securing said annular ring to said housing boss in a fixed position relative to said stationary coaxial housing at any rotational position of said annular ring and said secured bearing cup; wherein said annular ring includes at least one axially directed bore; and wherein said means for securing includes at least one component configured to extend through said at least one axially directed bore and to engage said housing boss of said stationary coaxial housing.
8. The bearing cup anti-rotation assembly of Claim 7 wherein at least one axially directed bore is configured to receive an advancement tool adapted to facilitate threaded rotational adjustment of said bearing cup within said housing boss, relative to said stationary coaxial housing. 9. (Cancelled)
10. (Cancelled)
11. (Cancelled)
12. (Cancelled)
13. A bearing cup anti-rotation assembly for securing a threaded bearing cup against axial and rotational movement relative to a threaded stationary coaxial housing, comprising: an annular ring secured to an outer axial face of said bearing cup, said annular ring having an outer circumference which is greater than an outer circumference of said bearing cup; and at least one locking component adapted to engage said annular ring with said stationary coaxial housing at any relative rotational position of said annular ring and said secured bearing cup; and wherein said locking component includes a protrusion adapted to engage a circumferential peripheral edge of said annular ring. 14. (Cancelled)
15. (Cancelled)
16. (Cancelled)
7. (Cancelled)
