摘要： A wind turbine includes a rotor shaft. The rotor shaft is mounted via a bearing assembly having a first bearing ring and a second bearing ring mounted to rotate in relation to the first bearing ring. A hydrostatically supported first friction bearing segment is disposed on the first bearing ring and interacts with a first friction face that is disposed on the second bearing ring. The first friction bearing segment is received in a receptacle pocket of the first bearing ring such that a first compression chamber is formed between the first bearing ring and the first friction bearing segment. The first friction bearing segment is configured such that a second compression chamber is formed between the first friction bearing segment and the second bearing ring, wherein the first compression chamber and the second compression chamber are connected by a duct that runs through the first friction bearing segment.

摘要： The invention relates to a process for producing a rolling bearing cage, in particular for large rolling bearings, wherein a steel strip with openings for in each case one rolling body is provided and bent to form a ring, wherein, for thermal coating with a thermoplastic powder, the ring is then heated to a temperature above a minimum coating temperature, wherein the ring is then dipped into a fluidized bed comprising the thermoplastic powder, wherein, during the residence time of the ring in the fluidized bed, plastic powder adheres to the ring, melts and forms a continuous coating, and wherein the ring is removed from the fluidized bed after the coating. The invention also relates to an apparatus for carrying out the process.

摘要： A tapered roller bearing may comprise an inner ring, an outer ring, and two rows of tapered rollers that are arranged in an O-arrangement between the inner ring and the outer ring. The inner ring may extend in an axial direction over a greater length than the outer ring, and a gap between the inner ring and the outer ring on at least one side of the tapered roller bearing may be sealed by a sealing assembly. The sealing assembly may comprise a main seal that is attached to the inner ring in a rotationally fixed manner, as well as a seal race ring that is attached to the outer ring in a rotationally fixed manner. The seal race ring may form a seal raceway for the main seal.

摘要： A magnetic bearing may include an inner ring and an outer ring arranged concentrically. The inner ring and the outer ring may be mounted rotatably relative to each other by way of axial and radial magnets. The magnetic bearing may also include a back-up bearing, which is integrated into at least one of the outer ring or the inner ring both in an axial direction and in a radial direction. The outer ring may be multipiece and may include a recess that opens inwards and receives the inner ring. Further, the back-up bearing may be made of aluminum, austenitic steel, bronze, or ceramic, and the back-up bearing may operate as a shielding device that shields magnetic fields emitted by the axial and radial magnets from one another.
