Abstract
There is disclosed herein an improved and simplified wheel and bearing assembly, such as for skates and the like comprising a bearing inner race preferably formed of a plastic material such as polysulfone. A pair of bearing outer races, preferably of a relatively strong material such as titanium or polysulfone, are coupled with outer surfaces of the bearing inner race. Mating surfaces of the bearing inner race and the bearing outer races are configured and are coated with a lubricant to provide bearing surfaces for the wheel. The wheel includes a tire with a glow-in-the-dark material or a reflective material.
Claims18
A wheel and bearing assembly comprising a bearing inner race having axially outwardly facing surfaces of a general “V” shape wherein the apexes of the “V” axially face outwardly, and having an outer circumference on which a tire is disposed, a pair of bearing outer races each having an inner surface configured to mate with the respective outwardly facing surfaces of the inner race, the inner surface including pockets to reduce the surface area facing the inner race, and the outer races having axial holes therethrough through which an axle can extend for supporting the wheel, and a film lubricant on the mating surfaces of the inner and outer races and in the pockets.
A wheel without ball or roller bearings comprising an inner race forming a hub and having axially outwardly facing surfaces of a general “V” shape wherein the apexes of the “V” axially face outwardly, and having an outer circumference on which a transparent or translucent tire may be disposed, the inner race having a plurality of light reflectors thereon, a pair of bearing outer races each having an axially extending inner surface configured to essentially mate with the respective outwardly facing surfaces of the inner race, the outer races each having an axial hole through which an axle can extend for supporting the wheel, and a dry film lubricant on the mating surfaces of the inner and outer races.
