摘要： A compressor includes a housing, a shaft that is rotated relative to the housing to compress a working fluid, and a foil bearing that supports the shaft. The foil bearing includes a top foil. The foil bearing is a foil gas bearing that is backed up by a ball bearing, or a mesh foil bearing with an actuator to compress a wire mesh dampener. A heat transfer circuit includes a compressor and a working fluid. The compressor includes a shaft that is rotated to compress the working fluid, and a foil bearing for supporting the shaft as it rotates.

摘要： A parallel bearing includes a rotary shaft bearing and a stator bearing, wherein the rotary shaft bearing is a contact bearing, and the rotary shaft bearing is sleeved on a rotary shaft; and the stator bearing is a non-contact bearing, the stator bearing is sleeved on the rotary shaft bearing, and a clearance is provided between the stator bearing and the rotary shaft bearing. The parallel bearing is cost-effective, reduces the relative rotational speed of each stage of bearing, breaks through the limitation of the theoretical DN factor and has the low dependency on the lubricating oil. In the rotor system having the parallel bearing, rotational speeds of multiple parallel bearings on the same rotary shaft can be adaptively adjusted to achieve the synchronous rotation, and thus the rotor system has the desired stability in high-speed operation.

摘要： A bearing assembly includes an outer race having an inner surface defining a concave contour and an inner race positioned in the outer race. The inner race has an inner surface defining a bore therethrough and an outer surface defining at least one groove circumscribing the outer surface. A plurality of rolling elements is rollably located in the groove and is in rolling contact with the inner surface of the outer race. A lubricious liner has an inner liner-surface and an exterior liner-surface, the exterior liner-surface being disposed on the inner surface defining the bore. The lubricious liner has a modulus of compression of a magnitude sufficient to allow misalignment of the inner liner-surface relative to the exterior liner-surface in response to a force applied thereto.

摘要： A bearing assembly may include a first bearing ring, a second bearing ring, and at least one row of rolling elements having a plurality of rolling elements that are disposed so as to be capable of rolling on a first raceway of the first bearing ring and on a second raceway of the second bearing ring. At least one hydrostatically supported first sliding bearing segment may be disposed on the first bearing ring. Further, the hydrostatically supported first sliding bearing segment may interact with a first bearing face that is disposed on the second bearing ring. The hydrostatically supported first sliding bearing segment may be mounted so as to be movable in a movement direction that is perpendicular to the first bearing face.

摘要： A slew bearing includes a stationary bearing ring to be fixed to a base, a moveable bearing ring to be fixed to a moveable object, wherein the stationary bearing ring and the moveable bearing ring are configured to enable rotation of the moveable bearing ring relative to the stationary bearing ring about a rotation axis. A main axial bearing and an auxiliary bearing are provided between the stationary bearing ring and the moveable bearing ring, wherein the moveable bearing ring includes one or more main portions and one or more auxiliary portions, which one or more main portions are moveable relative to the one or more auxiliary portions between an operational position, in which the main axial bearing transfers the axial loads between moveable bearing ring and stationary bearing ring, and a maintenance position, in which the auxiliary axial bearing transfers the axial loads between moveable bearing ring and stationary bearing ring and the main bearing is allowed to be inspected and/or maintained so that the slew bearing during inspection and/or maintenance is still operational.

摘要： A bearing arrangement having: a first element having an inner race and a first bearing surface; a second element, pivotable relative to the first element about a first axis, and having an outer race and a second bearing surface that cooperates with the first bearing surface to form a plain bearing. The bearing arrangement also includes a roller element disposed between the inner and outer races to form a rolling bearing. The inner and outer races are arcuate and subtend an angle of less than 360° about the first axis.

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： A roller bearing configured to be mounted on a balancing shaft. The rolling bearing having an outer ring, a cage axially protruding beyond at least one side of the outer ring, and rollers mounted in the cage and in rolling contact with the outer ring. The cage provides at least one boss on a side that axially protrudes beyond the outer ring, the boss being dedicated to come into abutment against the outer ring in case of relative axial displacement between the cage and outer ring.

摘要： A universal joint includes a bearing including a bearing cup fitted in a bearing hole of a yoke and rolling elements arranged between the bearing cup and a shaft portion of a cross shaft. A method for manufacturing the universal joint includes: simulating a shrunken state in which a sample bearing cup selected from bearing cups in a same lot is fitted in the bearing hole such that only an outside diameter is restrained, by press-fitting the sample bearing cup into a reference hole of a reference jig; measuring a diameter of an inscribed circle inscribed to the rolling elements in the shrunken state; setting an outside diameter of the shaft portion to a required outside diameter according to the diameter of the inscribed circle; and inserting the bearing cup with the rolling elements between the shaft portion having the required outside diameter and the bearing hole.
