摘要： Various teachings herein may be used to make a bearing bush for a rotating shaft, wherein a wall of the bearing bush has a wall thickness which amounts to less than 10% of the diameter of the bearing bush. In the axial direction, the bearing bush is made from a plurality of layers connected with a material bond. Each layer has a layer thickness between 10 μm and 200 μm and the wall has closed cavities which are filled with a powder.

摘要： The disclosure relates to a steer-by-wire system for a motor vehicle including a steering rod, an electric servo unit configured to move the steering rod, and a sliding bearing which radially supports the steering rod in a housing. The housing, the sliding bearing, and the steering rod have complementary geometries whereby the steering rod is prevented from rotating. The sliding bearing includes multiple segments in the circumferential direction, at least one segment of the multiple segments is a sliding bearing location for the radial support. At least one segment of the multiple segments is a first supporting element configured to prevent rotation in one direction of rotation. At least one segment of the multiple segments is a second supporting element configured to prevent rotation in the opposite direction of rotation.

摘要： An assembly is provided for a turbine engine. This assembly includes a stationary structure, a rotating structure, a magnetic-foil bearing and a cooling system. The rotating structure is rotatable about an axis. The magnetic-foil bearing radially supports the rotating structure within the stationary structure. The magnetic-foil bearing includes a magnetic bearing stator, a magnetic bearing rotor and a foil bearing. The foil bearing is disposed radially between the magnetic bearing stator and the magnetic bearing rotor. The cooling system includes a cooling circuit configured to deliver cooling air to at least a first bearing component. The first bearing component is configured as or otherwise includes one of the magnetic bearing stator, the magnetic bearing rotor and the foil bearing.

摘要： A bearing assembly is provided that includes a frame, a magnetic bearing stator and a foil bearing. The frame extends axially along and circumferentially about an axis. The frame includes an inner bore and a plurality of channels arranged circumferentially about the axis. The magnetic bearing stator includes a stator body and a plurality of windings. The stator body circumscribes the frame. The stator body includes a plurality of stator protrusions arranged circumferentially about the axis. Each of the stator protrusions projects radially inward into a respective one of the channels. Each of the windings is wrapped around a respective one of the stator protrusions. The foil bearing is disposed within the inner bore and retained to the frame.

摘要： Devices and method include relatively moving elements having one or more bearing surfaces defining a gap between the elements into which a fluid is received. At least one of the bearing surfaces comprises a varying topography to provide pressurized volumes of the fluid in order to define a hydraulic bearing to support at least one of the elements during movement.

摘要： There are provided sliding components that allow sliding surfaces to smoothly slide against each other regardless of whether a relative rotation direction is a forward rotation or a reverse rotation. The sliding components and include: a pair of sliding surfaces and disposed to face each other at a location where a relative rotation takes place when a rotating machine is driven. The sliding surface is provided with a first dynamic pressure generating groove communicating with a radially outer-side space and extending in one circumferential direction, a second dynamic pressure generating groove extending in the opposed circumferential direction, and a conduit groove communicating with the space. The conduit groove includes an annular groove and a communication groove communicating between the annular groove and the space. The second dynamic pressure generating groove is disposed closer to the space than the annular groove, and communicates with the annular groove.

摘要： Provided is a journal foil air bearing for supporting a load applied along a radial direction of a rotating shaft rotating about a centerline, the journal foil air bearing including a first top foil disposed to face an outer circumferential surface of the rotating shaft and surround the rotating shaft, a second top foil disposed to surround the first top foil, a bump foil provided as an elastically deformable member and disposed to surround the second top foil, a base foil disposed to surround the bump foil, and at least one separation preventer provided on the first top foil to restrain the first top foil from being separated along a longitudinal direction of the rotating shaft, wherein the separation preventer protrudes a preset length toward the second top foil and is restrained by the second top foil from moving in the longitudinal direction of the rotating shaft. According to the present invention, because the first top foil does not escape in the longitudinal direction of the rotating shaft during operation, the performance of the bearing may not be reduced and serious secondary damage due to the contact between the escaped first top foil and other components may not be caused.
