Patent number: 9388852Abstract: A rolling bearing, particularly for a gas turbine, includes a plurality of rolling elements (4) arranged between an inner ring (2) and outer ring (3), and a housing structure (8) on which the outer ring (3) is elastically mounted. The outer ring (3) is constructed in one piece and has a raceway section (7) forming a raceway (6) for the rolling elements (4), a spring section (21) and a flange (10) screwed to the housing structure (8). The spring section (21) is constructed from a plurality of spring bars (12) which adjoin a deflection section (9) adjoining the raceway section (7) at the end face thereof and adjoin the flange (10), are arranged radially outside the raceway section (7) and do not protrude axially beyond the deflection section (9) and the race way section (7).Type: GrantFiled: August 28, 2013Date of Patent: July 12, 2016Assignee: Schaeffler Technologies AG & Co. KGInventors: Johannes Bedenk, Christian Pröschel

Patent number: 8992093Abstract: A wheel bearing for aircraft, that has a long service life and is reliable. The wheel bearing has a small number of individual parts and components that are simple to handle, to mount or to dismount. The wheel bearing of an aircraft landing gear has a wheel rim that is rotationally mounted about an axis over two roller bearings of a bearing arrangement. The external rings of the roller bearings are received together in a single-piece external ring bearing housing. The wheel rim can be detachably connected to the bearing arrangement in such a manner that it can be mounted or dismounted independently from the bearing arrangement.Type: GrantFiled: August 27, 2008Date of Patent: March 31, 2015Assignee: Schaeffler Technologies AG & Co. KGInventors: Torsten Dotzel, Robin Lang, Christian Proeschel, Wilhelm Sebald, Gerhard Kreiselmeier

Patent number: 8444324Abstract: A wheel bearing for aircraft. The bearing has a long service life, is very reliable and consists of the lowest possible number of individual parts. The wheel bearing of an aircraft engine has a rim that is rotatably mounted about an axis by a bearing arrangement which has two rolling bearings. An outer bearing housing, designed as one piece, contains the outer running surfaces of the rolling bearings. An integral component of the outer bearing housing forms part of the rim and the outer bearing housing is detachably connected to the remainder of the rim.Type: GrantFiled: December 2, 2008Date of Patent: May 21, 2013Assignee: Schaeffler Technologies AG & Co.

Patent number: 8439571Abstract: A sealing arrangement which has a long or increased service life and high reliability even in soiled or aggressive surroundings. The sealing arrangement for a bearing has a first bearing ring and second bearing, which is rotatable relative to the first bearing ring, and a seal that is arranged in the region of the first bearing ring and that extends in the direction of the bearing periphery. The second bearing ring has a peripheral scaling surface and the seal has at least two peripheral sealing lips that sealingly rest on the sealing surface.Type: GrantFiled: August 27, 2008Date of Patent: May 14, 2013Assignee: Schaeffler Technologies AG & Co.

Publication number: 20110110618Abstract: A bearing ring which is has a reliable and maintenance-free protection from frictional corrosion on the fits of the bearing ring. The protection is already effective during assembly. The bearing ring has a wall that has a frictional corrosion-resistant layer in at least those regions that are in contact with a machine component via a fit when assembled.Type: ApplicationFiled: August 27, 2008Publication date: May 12, 2011Applicant: SCHAEFFLER TECHNOLOGIES GMBH & CO.
