Abstract
Abstract A bicycle wheel or pedal crank hub with a bearing preload device in which an axle end cap that is attached to the end of an axle extending through the hub and supported on a bearing assembly is used for preloading the hub bearing assembly together with a split compression ring. For adjusting the preload on the hub bearing assembly, the compression ring is expanded or contracted causing a beveled surface of the compression ring to act on a bevel of either an annular circumferential flange of the axle end cap or a spacer disposed between the compression ring and the circumferential flange of the axle end cap.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
149 words
A bicycle hub with a bearing preload device comprising: a cylindrical hub having two ends, said hub including a passage extending from one end of said hub, through said hub, to the other end of said hub; a hub bearing assembly positioned in said passage; an axle positioned within said passage of said hub and rotatably supported upon said bearing assembly; an axle end cap adjustably and detachably attached to an end of said axle, said axle end cap having a circumferential flange; a compression means for adjusting an axial preload on the hub bearing by expansion and contraction thereof; said compression means being positioned around said axle end cap between the circumferential flange of said axle end cap and said hub bearing assembly and in engagement therewith; wherein said circumferential flange of said axle end cap has a bevel at a side thereof which faces the bearing assembly.
Claim 2
Dependent Claim
149 words
A bicycle hub with a bearing preload device comprising: a cylindrical hub having two ends, said hub including a passage extending from one end of said hub, through said hub, to the other end of said hub; a hub bearing assembly positioned in said passage; an axle positioned within said passage of said hub and rotatably supported upon said bearing assembly; an axle end cap adjustably and detachably attached to an end of said axle, said axle end cap having a circumferential flange; a compression means for adjusting an axial preload on the hub bearing by expansion and contraction thereof; said compression means being positioned around said axle end cap between the circumferential flange of said axle end cap and said hub bearing assembly and in engagement therewith; wherein said circumferential flange of said axle end cap has a bevel at a side thereof which faces the bearing assembly.
