Abstract

A bearing comprising: (a) an inner ring, (b) an outer ring, and (c) a bearing liner disposed therebetween, wherein the bearing liner comprises a resin having a glass transition temperature of less than 150° C.

First claim

The invention claimed is:

1. A bearing comprising:
an inner ring,
an outer ring, and
a first fabric impregnated with a resin having a glass transition temperature of less than 150° C.,
a second fabric,
a bearing liner formed by contacting and compressing together the first fabric and the second fabric, whereby at least some of the resin in the first fabric transfers to the second fabric, the bearing layer being disposed between the inner ring and the outer ring.

2. The bearing of claim 1 , wherein the resin has a glass transition temperature of from 100° C. to 140° C.

3. The bearing of claim 1 , wherein the resin has a glass transition temperature of from 120° C. to 130° C.

4. The bearing of claim 1 , wherein the resin is an epoxy resin.

5. The bearing of claim 1 , wherein the first fabric is a woven fabric.

6. The bearing of claim 5 , wherein the woven fabric comprises:
a bearing element contact surface comprising lubricating fibers, and
structural fibers supporting the bearing element contact surface.

7. The bearing of claim 6 , wherein the lubricating fibers comprise PTFE or graphite.

8. The bearing of claim 6 , wherein the structural fibers comprise at least one of:
glass,
carbon fiber,
aramid,
polyether ether ketone,
polyester,
polyamide, and
polyphenylene sulphide.

9. A bearing comprising:
a ring,
a first fabric impregnated with a resin having a glass transition temperature of less than 150° C.,
a second fabric, and
a bearing liner formed by contacting and compressing together the first fabric and the second fabric, whereby at least some of the resin in the first fabric transfers to the second fabric, the bearing layer being disposed on at least one of an inner surface and an outer surface of the ring.

10. The bearing of claim 9 , wherein the bearing is a self-lubricating bearing.

11. The bearing of claim 9 , wherein the bearing is a rotary aircraft bearing.

12. The bearing of claim 11 , wherein the rotary aircraft bearing is integrated into a rotary aircraft.

13. A method of manufacturing a bearing liner for use in a bearing, the method comprising:
providing a first fabric impregnated with a resin having a glass transition temperature of less than 150° C.,
providing a second fabric, and
contacting and compressing together the first fabric and the second fabric, whereby at least some of the resin in the first fabric transfers to the second fabric,
integrating the bearing liner into a bearing, wherein the bearing comprises:
an inner ring, and
an outer ring,

wherein the bearing liner is disposed between the inner ring and the outer ring.
