Patent ID: 7941085

Claim:
A system for stabilizing a fuser core in an imaging device comprising: a fuser core having a body defined by an outside diameter, a first end, and a second end opposite the first end, wherein the first end is formed by a first cavity having a first ratchet type geometric profile about the surface of the first cavity, and wherein the second end is formed by a second cavity having a second ratchet type geometric profile about the surface of the second cavity; a first hub having an end defined by an exterior surface, wherein the exterior surface includes a ratchet type geometric profile configured to mate with the first cavity, wherein the exterior surface of the first hub is at least partially disposed inside the first end; and a second hub having an end defined by an exterior surface, wherein the exterior surface includes a ratchet type geometric profile configured to mate with the second cavity; wherein the exterior surface of the second hub is at least partially disposed inside the second end, wherein the first ratchet type geometric profile is comprised by at least two opposite circular arcs, the arcs oriented 180 degrees apart, whereas a circle is defined as a subset of an ellipse, and the arcs are defined by a curve which is a portion of a circle whereby the center of the circle is offset from a minor diameter circle, and each opposing arc is a portion of a circle whereby the center of the circle is offset and equal but opposite distance along a straight line from the center of the minor circle, wherein the distance from the center of the minor circle defines a height or depth of the arc, depending upon if the arcs are inscribed on an exterior or interior surface.
