Publication number: 20110133412Abstract: A seal arrangement between two components moving relative to one another. The seal arrangement has a seal which is positioned by way of a seal back in an annular groove of a fixed rolling bearing ring. The seal has at least two elastic sealing lips, a first, radial scaling lip supported by a spring means and a second, axial sealing lip, which are each supported by at least one sealing edge directly or indirectly against a rotating centrifugal sleeve. An intermediate space defined by the sealing edges of the sealing lips is designed as lubricant reservoir. Alternatively or in addition, at least one sealing edge forms a lubricant reservoir in the area of a contact zone of the sealing edge against a support face of the centrifugal sleeve or offset in relation thereto.Type: ApplicationFiled: December 8, 2010Publication date: June 9, 2011Applicant: SCHAEFFLER TECHNOLOGIES GMBH & CO. KGInventors: Elmar MAUSE, Gerald LOESLEIN, Akira MATSUNO

Publication number: 20080199319Abstract: The invention refers to an impeller, consisting of plastic, which Is intended for a coolant pump of an internal combustion engine. The impeller, which has a multipart construction, comprises a back wall, which is connected in one piece to guide vanes and also to a hub, and also a separate molded disk which on the end face partially covers the guide vanes in the installed state. The components, the back wall and the molded disk are positionally fixed by means of a materially bonding connection.Type: ApplicationFiled: June 17, 2006Publication date: August 21, 2008Applicant: SCHAEFFLER KGInventors: Elmar Mause, Patrick Jahnke, Thomas Traudt

Patent number: 7066471Abstract: A lip-type shaft seal is made of elastic material with a Shore A hardness of ?75, includes a radial sealing lip, which has a sealing edge to bear against a rotating component and terminates in a axial sealing lip, which has a sealing edge to rests in installed state against a contact surface. The axial sealing lip extends at an angle of ?35° in relation to a symmetry axis of the shaft seal, when the axial sealing lip has not been installed yet and is under no tension, and extends from the sealing edge of the radial sealing lip at a length of ?1.4 mm. When the shaft seal is installed, the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm.Type: GrantFiled: October 2, 2003Date of Patent: June 27, 2006Assignee: INA-Schaeffler KGInventors: Elmar Mause, Harald Peschke, Wolfram Kruhöffer, Thomas Traudt, Horst Krischer

Publication number: 20040113366Abstract: A lip-type shaft seal is made of elastic material with a Shore A hardness of ≦75, includes a radial sealing lip, which has a sealing edge to bear against a rotating component and terminates in a axial sealing lip, which has a sealing edge to rests in installed state against a contact surface. The axial sealing lip extends at an angle of ≧35° in relation to a symmetry axis of the shaft seal, when the axial sealing lip has not been installed yet and is under no tension, and extends from the sealing edge of the radial sealing lip at a length of ≧1.4 mm. When the shaft seal is installed, the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm.Type: ApplicationFiled: October 2, 2003Publication date: June 17, 2004Applicant: INA-SCHAEFFLER KGInventors: Elmar Mause, Harald Peschke, Wolfram Kruhoffer, Thomas Traudt, Horst Krischer

Patent number: 5690433Abstract: A system for preloading the bearing of a cooling water pump for motor vehicles. The pump comprises a shaft and an impeller mounted on one end of the shaft and, an outer bearing ring surrounding the shaft. An axial face seal is mounted on one projecting end of the shaft operable bearing ring and to tension spring-loaded sliding rings with a predetermined contact pressure against each other. The outer axial end face of the axial face seal is aligned with the axial end face of the shaft to simplify and insert the same preloading of the bearing for assemblies put together by mass production techniques.Type: GrantFiled: March 1, 1996Date of Patent: November 25, 1997Assignee: SKF GmbHInventors: Rudiger Hans, Elmar Mause

Patent number: 4911610Abstract: In a drive device for pumps consisting of a pump impeller mounted in a pump chamber, a pump cover covers the pump chamber and has an extension and a bore passing from the pump chamber to the outside. A shaft is connected at its inner end to the pump impeller and at its outer end in a torsion-proof manner by way of a coupling element to a drive wheel. A bearing supports the shaft and drive wheel in the housing bore and extension respectively. The coupling element is formed by an external edge rigidly connected to the drive wheel and covers the outer bearing and the extension laterally on the outside. A cover plate with a center section connects in a torsion-proof manner to the shaft, and is adjusted to elastically adjust the cover plate relative to the pump cover either inward toward the pump chamber or outward away from the pump chamber, thereby providing for automatic adjustment of the radial and axial load-supporting bearings means to remove their play.Type: GrantFiled: May 13, 1988Date of Patent: March 27, 1990Assignee: SKF GmbHInventors: Armin Olschewski, Manfred Brandenstein, Horst M. Ernst, Elmar Mause, Heinrich Kunkel

Patent number: 4865469Abstract: A bearing on a shaft is separated from the bore of a housing by an intermediate sleeve. The sleeve has an annular recess in its end surface, the end surface being spaced from the shaft. A sealing element extends radially in the annular recess and axially between the shaft and the intermediate sleeve. The axially extending arm of the sealing element has a flange extending behind a radially extending surface of the intermediate sleeve to axially hold the sealing element, with play, to the intermediate sleeve. The sealing element is mounted with prestress on the shaft, to rotate therewith during operation.Type: GrantFiled: April 22, 1988Date of Patent: September 12, 1989Assignee: SKF GmbHInventors: Roland Haas, Elmar Mause, Hans-Joachim Buchelmaier, Manfred Brandenstein

Patent number: 4560291Abstract: A cage for ball bearings consists of two side rings connected together by webs, and having ball pockets with ball pockets having curved partial surfaces inside and outside of the pitch circle and displaced from one another in the axial direction. In this arrangement the rubbing between the walls of the cage pockets and the balls is very small and free space is provided for receiving a lubricant. The pocket walls of the cage sections lying in the region of one or the other of the side rings has several radially-overlying zones, with conical surfaces, the conical surfaces being arranged at different inclinations to the bearing axis.Type: GrantFiled: December 23, 1983Date of Patent: December 24, 1985Assignee: SKF Kugellagerfabriken GmbHInventors: Roland Bonengel, Herbert Dobhan, Manfred Brandenstein, Ludwig Edelmann, Horst M.
