Patent number: 7798724Abstract: A bearing includes an inner bearing ring on which a raceway is formed. The ring includes at least a first component of light metal material and at least a second component of fully dense ceramic material, where the first component and the second component are separate entities joined together, and where the second component forms at least part of the raceway. The first component includes two lightweight metal parts interconnected by a screw thread which can be tightened to induce compressive pre-stress in the second component to compensate for low tensile strength of the ceramic material.Type: GrantFiled: July 15, 2005Date of Patent: September 21, 2010Assignee: AB SKFInventors: Johannes Franciscus Van De Sanden, Martinus Maria Jozef Noordman, Alexander Jan Carel De Vries, Peggy Suzanne Charlotte Vieillard

Patent number: 6367592Abstract: An actuator for use in a brake caliper is situated at opposite ends of a screw mechanism. A reduction gear mechanism is located at a distance from the actuating member. The reduction gear mechanism is included in a reduction gear module and a screw mechanism is contained in a screw mechanism module, which are interconnected through a drive module. The drive module may be located at the end of the reduction gear module facing away from the screw mechanism module. The modules may be axially aligned or at least two modules may be axially shifted or eccentric with respect to each other. The screw mechanism module may comprise an angular contact bearing which may be supported in a housing in different ways. The reduction gear module may be part of a planetary gear system.Type: GrantFiled: October 24, 2000Date of Patent: April 9, 2002Assignee: SKF Engineering and Research Centre B.V.Inventors: Hendrikus Jan Kapaan, Jacobus Zwarts, Andries Christian Rinsma, Johannes Albertus Van Winden, Clair Druet, Alexander Jan Carel De Vries, Armin Herbert Emil August Olschewski, Thomas Wilhelm Fucks
