Lock nut with offset retaining ring

1. A lock nut system comprising:

a nut having a plurality of nut teeth along an inner circumferential portion, said nut being threadably engageable with a shaft;

a retaining member engageable with the nut;

a keeper coupled to the retaining member and having a plurality of locking teeth configured to engage with said plurality of nut teeth, said keeper having a protrusion configured to fit within a recess of said shaft;

wherein said plurality of locking teeth are offset relative to said protrusion so that a first distance between the protrusion and a first full locking tooth located on the clockwise side of the protrusion is not equal to a second distance between the protrusion and a second full locking tooth located on the counterclockwise side of the protrusion; and

wherein said locking teeth engage with said nut teeth to lock said nut into position on said shaft when (i) the nut is threadably engaged to the shaft with the retaining member engaged to the nut and (ii) the protrusion is within the recess of the shaft.

2. The lock nut system of claim 1 , wherein said protrusion extends radially inward toward the central axis of said nut when said retaining member is engaged to said nut.

3. The lock nut system as recited in claim 2 , wherein the nut comprises at least one recess configured to receive the retaining member therein.

4. The lock nut system as recited in claim 3 , wherein the recess comprises a circular recess extending within an inside surface of the nut.

5. The lock nut system as recited in claim 4 , wherein the retaining member extends continuously in an arc when within said recess and engaged with said nut.

6. The lock nut system as recited in claim 5 , wherein the nut comprises a bearing retaining nut.

7. The lock nut system of claim 6 , wherein said retaining member comprises at least one leg configured to be received in said circular recess.

8. The lock nut system of claim 7 , wherein said at least one leg comprises two legs elastically deformable toward one another to allow said retaining member to be engaged to said nut by inserting said two legs in said circular recess.

9. The lock nut system of claim 1 , wherein the plurality of locking teeth are offset in a clockwise direction such that the first distance is greater than the second distance.

10. The lock nut system of claim 1 , wherein the plurality of locking teeth are offset in a counterclockwise direction such that the second distance is greater than the first distance.

11. A retaining apparatus for lock nut system useable with a nut having a plurality of nut teeth along an inner circumferential portion, said nut being threadably engageable with a shaft, the apparatus comprising:

a retaining member engageable with the nut;

at least one keeper configured to couple to the retaining member and having a plurality of locking teeth configured to engage with said plurality of nut teeth, said keeper having a protrusion configured to fit within a recess of said shaft;

wherein said plurality of locking teeth are offset relative to said protrusion a so that a first distance between the protrusion and a first full locking tooth located on the clockwise side of the protrusion is not equal to a second distance between the protrusion and a second full locking tooth located on the counterclockwise side of the protrusion; and

wherein said locking teeth are configured to engage with said nut teeth to lock said nut into position on said shaft when (i) the nut is threadably engaged to the shaft with the retaining member and one keeper being engaged to the nut and (ii) the protrusion is within the recess of the shaft.

12. The lock nut system of claim 11 , wherein said protrusion extends radially inward toward the central axis of said nut when said retaining member is engaged to said nut.

13. The lock nut system as recited in claim 12 , wherein the retaining member extends continuously in an arc.

14. The lock nut system of claim 11 , wherein the plurality of locking teeth are offset in a clockwise direction such that the first distance is greater than the second distance.

15. The lock nut system of claim 11 , wherein the plurality of locking teeth are offset in a counterclockwise direction such that the second distance is greater than the first distance.

16. The lock nut system of claim 11 , comprising a first keeper with the plurality of locking teeth being offset in a clockwise direction such that the first distance is greater than the second distance, and a second keeper with the plurality of locking teeth being offset in a counterclockwise direction such that the second distance is greater than the first distance.

17. A method comprising:

providing a retaining member engageable with a nut, the nut having a plurality of nut teeth along an inner circumferential portion and being threadably engageable with a shaft;

configuring a keeper with a protrusion sized to fit within a recess of said shaft and coupling the keeper to the retaining member;

configuring a plurality of locking teeth on the keeper to engage with the plurality of nut teeth wherein said plurality of locking teeth are offset relative to the protrusion so that a first distance between the protrusion and a first full locking tooth located on the clockwise side of the protrusion is not equal to a second distance between the protrusion and a second full locking tooth located on the counterclockwise side of the protrusion; and

wherein said locking teeth engage with said nut teeth to lock said nut into position on said shaft when (i) the nut is threadably engaged to the shaft with the retaining member engaged to the nut and (ii) the protrusion is within the recess of the shaft.

18. The method of claim 17 , wherein said protrusion extends radially inward toward the central axis of said nut when said retaining member is engaged to said nut.

19. The method of claim 17 , wherein the retaining member extends continuously in an arc.

20. The method of claim 17 , wherein the plurality of locking teeth are offset in a clockwise direction such that the first distance is greater than the second distance.

21. The method of claim 17 , wherein the plurality of locking teeth are offset in a counterclockwise direction such that the second distance is greater than the first distance.
