Patent number: 7037026Abstract: A method for mounting an axially split sleeve provided with an axial slot on a shaft so that a tapering surface on the sleeve cooperates with a tapering bore of a machine member. A flange is axially connected to the sleeve and supports a number of spaced apart tightening devices that are to be urged against the machine member for mutually displacing the machine member and the sleeve to increase the grip between the shaft, the sleeve and the machine member. The method involves positioning the sleeve around the shaft with the annular flange positioned with its tightening devices against the machine member, tightening a first one of the tightening devices which is located at a position diametrically opposite the slot in the sleeve, and thereafter tightening further ones of the tightening devices one by one.Type: GrantFiled: November 15, 2002Date of Patent: May 2, 2006Assignee: AB SKFInventors: Sture Östling, Uno Axelsson

Patent number: 6736027Abstract: 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.Type: GrantFiled: April 23, 2002Date of Patent: May 18, 2004Assignee: Aktiebolaget SKFInventors: Sture Östling, Uno Axelsson

Patent number: 6375383Abstract: An attachment device for arresting a machine member having a substantially cylindrical bore on a cylindrical shaft includes first and second sleeve members adapted to be positioned in a space between the outer surface of the shaft and the inner surface of the bore in the machine member. The two sleeve members have mating, cooperating taper surfaces in the form of a plurality of saw-tooth-shaped axially tapering sections that face one another. At least one of the sleeve members is movable for displacement relative to the other sleeve member to change the radial size of at least one of the sleeve members. The end edge of the first sleeve member projects axially beyond an adjacent end edge of the second sleeve member for receiving an external pushing force causing the first element to be displaced relative to the second element to cause the relative displacement of the sleeve members. The opposite end edge of the second sleeve members engages a stop that may be formed on the machine member.Type: GrantFiled: May 11, 2000Date of Patent: April 23, 2002Assignee: SKF Mekan ABInventors: Sture Östling, Uno Axelsson
