Abstract
An attachment device for a bore-provided machine member on a cylindrical shaft. A two-part sleeve is arranged in an annular space between the shaft and the machine member to provide a clamping force between the machine member and the shaft. The sleeve parts have mating cooperating taper surfaces that face each other so that upon mutual displacement of the sleeve parts the overall radial size of the sleeve parts changes. A first ring member is arranged about the shaft and forms a stop for one of the sleeve parts and a supporting device is adapted to move the machine member with respect to the shaft to cause mutual displacement of the sleeve parts. A second ring member positioned between the two-part sleeve and the machine member has a tapering bore, a tapering outer surface, and an inwardly projecting abutment for a second one of the sleeve parts.
