Abstract

A component for a bearing including a substrate having opposite major surfaces spaced apart by a thickness of the substrate, and a plurality of channels extending along the first surface, at least two of the plurality of channels extending in parallel with each other, wherein at least one of the plurality of channels is adapted to receive and secure a polymeric material to the substrate. A method of forming a bearing including providing a substrate having a opposite major surfaces spaced apart by a thickness, forming channels in the substrate, the channels each having a depth extending from the first major surface toward the second major surface, applying a polymeric material to at least a portion of the first major surface, wherein a portion of the polymeric material occupies at least a portion of at least one of the channels, and curing the polymeric material.

First claim

What is claimed is:

1 . A component for a bearing comprising:
a substrate having a first and a second opposite major surfaces spaced apart by a thickness of the substrate; and a plurality of channels extending along the first surface, at least two of the plurality of channels extending in parallel with each other, wherein at least one of the plurality of channels is adapted to receive and secure a polymeric material to the substrate.

2 . The component according to claim 1 , further comprising a plurality of second channels disposed along the second major surface of the substrate.

3 . The component according to claim 1 , wherein at least one of the channels includes a throttled open end.

4 . The component according to claim 1 , wherein the minimum width of each channel is located along a plane defined by the first major surface.

5 . The component according to claim 1 , wherein, when viewed in cross section, at least one of the channels has a rounded bottom portion, as defined by a portion of the channel closest to the second major surface.

6 . A bearing comprising:
a substrate having:
a first and a second opposite major surfaces spaced apart by a thickness of the substrate; and
a plurality of channels extending along the first major surface, at least two of the plurality of channels extending in parallel with each other; and
a polymeric material disposed within at least one of the plurality of channels, the polymeric material covering at least a portion of the first major surface of the substrate.

7 . The bearing according to claim 6 , wherein the minimum width of each channel is located along a plane defined by the first major surface.

8 . The bearing according to claim 6 , wherein, when viewed in cross section, at least one of the channels has a rounded bottom portion, as defined by a portion of the channel closest to the second major surface.

9 . The bearing according to claim 6 , wherein at least one of the channels extends along an entire length of the first major surface.

10 . The bearing according to claim 6 , further comprising a plurality of second channels disposed along the second major surface of the substrate.

11 . The bearing according to claim 6 , wherein the substrate further comprises a zinc coating.

12 . The bearing according to claim 6 , wherein at least one of the channels includes a throttled open end.

13 . A method of forming a bearing comprising:
providing a substrate having a first and a second opposite major surfaces spaced apart by a thickness; forming channels in the substrate, the channels each having a depth extending from the first major surface toward the second major surface; applying a polymeric material to at least a portion of the first major surface, wherein a portion of the polymeric material occupies at least a portion of at least one of the channels; and curing the polymeric material.

14 . The method according to claim 13 , wherein the process of forming the channels is performed by micro-machining.

15 . The method according to claim 13 , wherein the process of forming channels is at least partially performed by removing material from the substrate with a diamond micro-wheel.

16 . The method according to claim 13 , wherein the process of applying the polymeric material is performed without depositing an intermediary layer between the substrate and the polymeric material.

17 . The method according to claim 13 , wherein the process of applying the polymeric material is performed such that the polymeric material directly contacts the substrate and a portion of at least one of the channels.

18 . The method according to claim 13 , further comprising:
forming a second plurality of channels in the substrate extending from the second major surface toward the first major surface.

19 . The method according to claim 13 , further comprising:
shaping the substrate and polymeric material to form an annular ring.

20 . The method according to claim 19 , further comprising:
attaching first and second circumferential ends of the annular ring together.
