Abstract

A wheel retention nut includes a body having a front face and a rear face. A central bore with internal threads extends through the body. A first outer perimeter of a first diameter is positioned adjacent to the front face. The first outer perimeter defines a polygon adapted to receive a wrench. A second outer perimeter of a second diameter, which is larger than the first diameter, is positioned adjacent to the rear face. The second outer perimeter is sized to retain an eccentrically rotating wheel.

Claims

1. A wheel retention nut, comprising:

a body having a front face and a rear face;

a central bore with internal threads extending through the body;

a first outer perimeter of a first diameter adjacent to the front face, the first outer perimeter defining a polygon adapted to receive a wrench; and

a second outer perimeter of a second diameter, larger than the first diameter, adjacent to the rear face, the second outer perimeter being sized to retain an eccentrically rotating wheel.

2. The wheel retention nut as defined in claim 1, wherein the body has a cavity in the front face which is adapted to receive a split retaining ring, the split retaining ring being adapted to engage a shaft to retain the body on the shaft.

3. The wheel retention nut as defined in claim 2, wherein the cavity has an internal surface with first engagement means and the split retaining ring has second engagement means, the first engagement means and the second engagement means engaging to maintain the body in a selected rotational position on the shaft.
