Bearing retainer assembly and method
View Patent ↗A bearing assembly and method includes a two-piece ball bearing retainer. The retainer has a first set of fluid passage apertures penetrating into ball bearing sockets, and has a supplemental set of fluid passage apertures penetrating from one side of the retainer to the other. The two halves can be snap fit together.
1. A retainer for use in a bearing assembly, the retainer comprising:
a generally circular body, comprising two halves, each half having alternating grooves and tongues;
a plurality of sockets disposed around the body, each circumferentially located between a groove and a tongue;
a plurality of apertures penetrating from outside of the body into at least some of the sockets; and
a plurality of supplemental apertures penetrating through the body from one side of the body to the other at the circumferential locations of the grooves and tongues, wherein the halves can be snapped together with respective grooves and tongues on one half engaging respective tongues and grooves on the other half to releasably join the halves, and wherein when the halves are joined the supplemental apertures on each half are then aligned in opposed pairs to each receive a fastener passing through the opposed supplemental aperture on each half, to provide supplemental attachment of the halves together.
2. A retainer according to claim 1 , wherein the sockets penetrate through the body.
3. A retainer according to claim 1 , wherein the sockets are outward facing.
4. A retainer according to claim 1 , wherein the sockets have a truncated spherical surface.
5. A retainer according to claim 1 , wherein the alternating grooves and tongues on one half have a substantially identical configuration to the grooves and tongues on the other half.
6. A retainer according to claim 5 , wherein the two halves are substantially identical to each other.
7. A retainer according to claim 1 , wherein the fasteners are each a threaded fastener.
8. A retainer according to claim 1 , wherein the fasteners are each a rivet.
9. A retainer for use in a bearing assembly, the retainer comprising:
a generally circular body, comprising two halves, each half having alternating grooves and tongues;
a plurality of sockets disposed around the body and circumferentially located between a groove and a tongue; and
a plurality of supplemental apertures penetrating through the body from one side of the body to the other at the circumferential locations of the grooves and tongues, wherein the halves can be snapped together with respective grooves and tongues on one half engaging respective tongues and grooves on the other half to releasably join the halves, and wherein when the halves are joined the supplemental apertures on each half are then aligned in opposed pairs to each receive a fastener passing through the supplemental aperture on each half, to provide supplemental attachment of the halves together.
10. A retainer according to claim 9 , wherein the alternating grooves and tongues on one half have a substantially identical configuration to the grooves and tongues on the other half.
11. A retainer according to claim 10 , wherein the two halves are substantially identical to each other.
12. A retainer according to claim 9 , wherein the fasteners are each a threaded fastener.
13. A retainer according to claim 9 , wherein the fasteners are each a rivet.
14. A retainer for use in a ball bearing assembly, the retainer comprising:
a generally circular shaped body, comprising two halves, each half having alternating grooves and tongues;
means for spacing the balls disposed around the body and circumferentially located between a groove and a tongue;
means for providing fluid passages each penetrating through the body from one side of the body to the sockets; and
a plurality of supplemental means for providing fluid passages each penetrating through the body from one side of the body to the other at the circumferential locations of the grooves and tongues, wherein the halves can be snapped together with respective grooves and tongues on one half engaging respective tongues and grooves on the other half to releasably join the halves, and wherein when the halves are joined the supplemental apertures on each half are then aligned in opposed pairs to each receive a fastener passing through the opposed supplemental aperture on each half, to provide supplemental attachment of the halves together.
15. A retainer according to claim 14 , wherein the alternating grooves and tongues on one half have a substantially identical configuration to the grooves and tongues on the other half.
16. A retainer according to claim 15 , wherein the two halves are substantially identical to each other.
17. A retainer according to claim 14 , wherein the fasteners are each a threaded fastener.
18. A retainer according to claim 14 , wherein the fasteners are each a rivet.
19. A kit for use in a bearing assembly, the kit comprising:
a retainer comprising:
a generally circular body, comprising two halves, each half having alternating grooves and tongues;
a plurality of sockets disposed around the body, each circumferentially located between a groove and a tongue;
a plurality of apertures penetrating from outside of the body into at least some of the sockets; and
a plurality of supplemental apertures penetrating through the body from one side of the body to the other at the circumferential locations of the grooves and tongues, wherein the halves can be snapped together with respective grooves and tongues on one half engaging respective tongues and grooves on the other half to releasably join the halves, and wherein when the halves are joined the supplemental apertures on each half are then aligned in opposed pairs to each receive a fastener passing through the opposed supplemental aperture on each half to provide supplemental attachment of the halves together.
20. A retainer according to claim 19 , wherein the alternating grooves and tongues on one half have a substantially identical configuration to the grooves and tongues on the other half.
21. A retainer according to claim 20 , wherein the two halves are substantially identical to each other.
22. A retainer according to claim 19 , wherein the fasteners are each a threaded fastener.
23. A retainer according to claim 19 , wherein the fasteners are each a rivet.
