Publication number: 20110299800Abstract: A bearing assembly comprises at least one bearing element abutting against at least one adjacent part at a contact surface. The bearing assembly can be manufactured by disposing a reactive nano-crystalline layer between the bearing element and the adjacent part in the area of the contact surface and then initiating an exothermic reaction in the reactive nano-crystalline layer, so that the bearing element bonds to the adjacent part in a materially-connected manner. The exothermic reaction involves at least partially heating the surface area of the bearing element and/or of the adjacent part that is located in the area of the contact surface.Type: ApplicationFiled: November 20, 2009Publication date: December 8, 2011Inventors: Stefanie Seufert, Helmut Hauck, Alexander Dilje, Hans-Jürgen Friedrich, Berthold Beyfuss, Alfred Radina, Jonas Schierling

Patent number: 6652150Abstract: A method for fixing at least one bearing in place in a bearing retainer involves positioning the bearing in the depression, providing an elastic element which acts in the axial direction on the bearing either before or after the bearing is positioned in the depression so that the elastic element is supported on the bearing in a first axial direction, and deforming a partial area of the bearing retainer so that the deformed partial area of the bearing retainer supports the elastic element in a second axial direction which extends opposite the first axial direction. A bearing arrangement produced according to the present invention includes a bearing retainer having at least one depression in which is positioned a bearing, with a portion of the bearing retainer overlapping a portion of the bearing to form an interlocking connection between the bearing retainer and the bearing in an axial direction.Type: GrantFiled: February 16, 2001Date of Patent: November 25, 2003Assignee: SKF GmbHInventors: Burkhard Buchheim, Berthold Beyfuss, Helmut Hauck, Peter Horling
