Lubricating surface having numerous protrusions

Abstract

Lubricating surfaces are disclosed suitable for sliding against other flat surfaces. These lubricating surfaces consist of multiple protrusions extending outward from the surface and employ solid or semi-solid lubricants such as grease between them. The resulting lubricating surfaces may be used in numerous applications and may be particularly useful for sliding surfaces used on a continuous or on an intermittent basis.

Claims

1. A lubricating surface assembly comprising: a top solid portion, and a lubricating agent;said top solid portion having a bottom surface;said bottom surface of said solid top solid portion having a plurality of protrusions extending from said bottom surface in an outward direction forming one or more cavities; and;said lubricating agent dispersed within said cavities of said bottom surface of said top solid portion thereby providing lubricating properties to other surfaces.

2. A lubricating surface assembly as recited in claim 1 wherein said protrusions are substantially spherical.

3. A lubricating surface assembly as recited in claim 1 wherein said protrusions have flat top geometry.

4. A lubricating surface assembly as recited in claim 2 wherein said protrusions have flat top geometry.
