Patent number: 9835203Abstract: A bearing arrangement is disclosed having a bearing and a bearing support. The bearing is coupled to the bearing support at an axial side. The bearing provides first and second bearing rings that define a bearing interior there between. A first groove is formed at the first bearing ring's radial side facing the second bearing ring. A coupling element is arranged at the bearing's axial side facing the bearing support. The coupling element includes a first, preferably nose-shaped, radial protrusion that is in engagement with the first groove, and a second radial protrusion, which at least partially encompasses the bearing support at a side facing away from the bearing, so that the coupling element fastens the bearing to the bearing support. A coupling element for such a bearing arrangement is also provided.Type: GrantFiled: April 22, 2016Date of Patent: December 5, 2017Assignee: AKTIEBOLAGET SKFInventors: Jürgen Barthelme, Alexander Dilje, Helmut Hauck, Daniel Ludwig, Stefanie Seufert

Patent number: 9103375Abstract: A cartridge bearing assembly for rotatably coupling a shaft with a housing includes a bearing having a central axis and opposing axial ends. The bearing includes first and second, axially spaced inner rings disposeable upon the shaft, at least one outer ring disposed circumferentially about the two inner rings, and first and second sets of rolling elements disposed between the inner and outer rings. A carrier includes a first tubular portion disposed generally about the bearing first axial end and a second tubular portion disposed generally about the bearing second axial end. The first and second tubular portions are coupled together to enclose the bearing, the carrier being at least partially disposeable within the housing bore so as to couple the bearing with the housing. Preferably, a coupler is provided to connect the first and second inner rings so as to establish preload within the bearing.Type: GrantFiled: December 14, 2012Date of Patent: August 11, 2015Assignee: AKTIEBOLAGET SKFInventors: Stefanie Seufert, Eric Rasolonjatovo, Thierry Poulle

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
