Abstract

A bearing liner comprising a fabric impregnated with a binder, the fabric comprising: (a) a bearing element contact surface comprising lubricating fibers and (b) structural fibers supporting the bearing element contact surface, wherein at least some of the structural fibers include a structural component and a lubricating component.

First claim

The invention claimed is:

1. A bearing liner comprising a fabric impregnated with a binder, the fabric comprising:
a bearing element contact surface including lubricating fibers, and
structural fibers supporting the bearing element contact surface,
wherein at least some of the structural fibers comprise a structural component and a lubricating component.

2. The bearing liner of claim 1 , wherein the lubricating fibers comprise PTFE or graphite.

3. The bearing liner of claim 1 , wherein the structural component of the structural fibers comprises at least one of
glass,
carbon fiber,
aramid,
polyether ether ketone,
polyester,
polyamide,
polyphenylene sulphide, and
aramid.

4. The bearing liner of claim 1 , wherein the lubricating component of the structural fibers comprises one of PTFE or graphite.

5. The bearing liner of claim 1 , wherein:
the structural component comprises aramid, and
the lubricating component comprises PTFE.

6. The bearing liner of claim 5 , wherein the structural fibers comprise:
from 10 to 30 wt. % aramid, and
from 70 to 90 wt. % PTFE.

7. The bearing liner of claim 1 , wherein the binder comprises a resin.

8. The bearing liner of claim 1 , wherein the binder comprises a phenolic resin.

9. A bearing including the bearing liner of claim 1 , wherein the bearing liner is integrated into the bearing, wherein the bearing liner is adapted to increase a working lifetime of the bearing.

10. A bearing including the bearing liner of claim 1 , further comprising:
an inner ring; and
an outer ring;
wherein the bearing liner is disposed between the inner ring and the outer ring.

11. The bearing of claim 10 , wherein the bearing is a plain bearing.

12. The bearing of claim 10 , wherein the bearing is a self-lubricating bearing.

13. The bearing of claim 10 , wherein the bearing is an aerospace bearing.

14. A bearing including the bearing liner of claim 1 , further comprising:
a ring;
wherein the bearing liner is disposed on an inner surface of the ring.

15. The bearing of claim 14 , wherein the bearing is a plain bearing.

16. The bearing of claim 14 , wherein the bearing is a self-lubricating bearing.

17. The bearing of claim 14 , wherein the bearing is an aerospace bearing.

18. A method of manufacturing a bearing liner, the method comprising steps of:
providing a first fabric impregnated with a binder,
providing a second fabric comprising a bearing element contact surface comprising lubricating fibers, and structural fibers supporting the bearing element contact surface, wherein at least some of the structural fibers comprise a structural component and a lubricating component, and
contacting and compressing together the first and second fabrics, whereby at least some of the binder in the first fabric transfers to the second fabric.
