  • Precision-balanced shaft and method
    Patent number: 6189196
    Abstract: A shaft assembly including an inner hub having a centrally-disposed bore therethrough and an outer surface for carrying a first member concentrically thereon for rotation therewith, an outer hub having a centrally-disposed bore therethrough and an outer surface for carrying a second member thereon for rotation therewith. The bore of the outer hub is adapted for receiving the inner hub concentrically therein for rotation therewith. An outer pressure-expansible sleeve is provided for being concentrically-mounted within the bore of said outer hub and pressurized for locking the outer hub onto the inner hub. An inner pressure-expansible sleeve is concentrically-positioned in the bore of the inner hub and pressurized for locking the inner hub onto a rotatable spindle, whereby the inner hub and outer hub and the respective members mounted thereon are locked in fixed, concentric relation relative to each other and to the rotatable spindle.
