Patent ID: 7296763

Claim:
A grinder roll assembly, comprising: a grinder roll having a through bore defined by a surface of the grinder roll; a shaft disposed within the through bore; a first tapered sleeve disposed between the shaft and the grinder roll surface such that a first end of the first tapered sleeve is proximate to a first end of the through bore, wherein the first end of the first tapered sleeve has a first thickness and a first locking ring flange extending therefrom, and a second end of the first tapered sleeve has a second thickness greater than the first thickness; a second tapered sleeve disposed between the shaft and the grinder roll surface such that a first end of the second tapered sleeve is proximate to the first end of the through bore, wherein the first end of the second tapered sleeve has a first thickness and a second locking ring flange extending therefrom, and a second end of the second tapered sleeve has a second thickness less than the first thickness; at least one connector for fastening together the first and the second locking ring flanges to thereby form a first friction lock between the first tapered sleeve and the second tapered sleeve, a second friction lock between the grinder roll and one of the first tapered sleeve and the second tapered sleeve, and a third friction lock between the shaft and the other one of the first tapered sleeve and the second tapered sleeve.
