Abstract

A nut with a coaxial bearing or dynamically brace-supporting independently-rotating, coaxial first and second cylindrical surfaces to each other. The nut has a fastener portion having a conventional nut configuration, and a bearing portion having a conventional bearing configuration. The fastener portion threadedly mounts to the threaded end of the independently-rotating, coaxial first cylindrical surface. The bearing portion is affixed to the fastener portion along an annular outer race, and supports an independently-rotating, coaxial second cylindrical surface along an annular inner race.

Claims

1. A nut for dynamically brace-supporting a first cylindrical surface having a threaded end to an independently-rotating, coaxial second cylindrical surface, said nut comprising:

a fastener portion having a first end, a second end, a multi-faceted exterior surface, and a cylindrically-shaped cavity with a central axis of rotation and a threaded inner surface for threadedly mounting to an externally threaded end of a first cylindrical surface at the first end; and

a bearing portion with an annular outer race coaxially aligned with and integrally affixed to said fastener portion at the second end, and an annular inner race having a radius less than radii of the annular outer race and the cylindrically-shaped cavity of the fastener portion and coaxially aligned with and rotatably secured to the annular outer race by conventional bearing means, said annular inner race for snugly supporting an independently-rotating coaxial second cylindrical surface extending therethrough.

2. A nut as in claim 1, wherein the fastener portion has an annular collar integrally formed on said second end, said annular collar having a radius greater than the radius of the annular outer race.

3. A nut as in claim 2, wherein the radius of the annular collar is less than the shortest radial distance of the multi-faceted exterior of the fastener portion.

4. A nut as in claim 2, wherein the annular outer race is supplementarily affixed to the annular collar.

5. A nut as in claim 1, wherein the multi-faceted exterior surface of the fastener portion has six equal faces of a conventional hexnut.
