Abstract: A parabolic-trough solar power plant includes at least one solar panel that has a shaft part supported by at least one bearing assembly configured to pivot the solar panel through a pivot angle about the longitudinal axis. The bearing assembly includes a support element with two support sections and a space therebetween, a chain element supported by the support sections, and a plurality of roller elements supported in the chain element along its longitudinal extension for rotation about an axis of rotation parallel to the longitudinal axis. Ends of the chain element are attached to the support sections by bearings that permit pivoting of the chain element relative to the support sections about a compensation axis horizontal, and in projection, perpendicular to the longitudinal axis of the shaft part. The roller elements are disposed at hinge points between pairs of the links in the chain.

Abstract: A device includes at least one stator and at least one flat motor rotor having at least one magnet unit configured to magnetically interact with the stator such that a drive force for rotating the flat motor rotor relative to the stator acts on the magnet unit. The device further includes at least one first bearing which contributes to rotatably supporting the flat motor rotor relative to the stator, and a second bearing which contributes to rotatably supporting the flat motor rotor relative to the stator. At least part of the first bearing abuts on one side of the flat motor rotor, and at least part of the second bearing abuts on the other side of the flat motor rotor, and the two bearings are preloaded against each other.

Abstract: A bearing system for supporting components that are movable relative to one another includes at least one bearing and a preload mechanism for changing a preload of the at least one bearing based on an operating state of the bearing system, where the preload mechanism includes, for example, a piezoelectric element, a Peltier element, an expansion material or a micromechanical element.

Abstract: A roller bearing comprises an inner ring, an outer ring and an annular cage. The annular cage retains and guides at least one roller body. The annular cage comprises at least one pocket for retaining the roller body and at least one retaining rim disposed on one axial end of the pocket. The retaining rim extends at least in the radial direction relative to a main body of the cage.

Abstract: A pressure generating device (1), such as a boost pressure generator of an internal combustion engine, includes a housing (2), in which a rotor (3) is axially and radially supported by a bearing assembly (5). A gap (4) extends in the radial direction (4) between the housing (2) and the rotor (3) at at least one axial position of the rotor (3). In order to ensure a minimal and constant gap between the housing and the rotor, an axial bearing (5?) is provided exclusively for supporting axial forces.

Abstract: A bearing unit rotatably supports a shaft of a pressure generating device, such a boost pressure generating device of an internal combustion engine. The bearing unit includes at least a first rolling-element bearing and a second rolling-element bearing, each rolling-element bearing having an inner ring and an outer ring. An annular space is defined between the respective inner and outer rings and rolling elements are disposed in the annular space. At least one volume element is disposed in the annular space and at least partially fills the annular space in an axial area.

Abstract: A process for mounting an outer bearing ring involves press fitting a stamp into the outer ring so that the inner peripheral surface of the outer ring assumes the shape of the stamp. Using the stamp, the outer ring is then press fitted into the recess of a machine part so that the contour of the external peripheral surface of the outer ring is plastically molded through axial stretching into the machine part. To mount an inner ring, a stamp with a bore is press fitted onto the inner ring so that the inner peripheral surface of the inner ring pressing against the stamp assumes the shape of the bore of the stamp. Using the stamp, the inner ring is then press fitted onto the machine part and the contour of the inner peripheral surface of the inner ring is plastically molded through axial flow forming into the machine part.

Abstract: A swivel mounting is made as a double-row roller bearing and has an outer ring with a first outer track and a second outer track, a first inner ring with a first inner track, and a second inner ring with a second inner track which is located axially next to the first inner ring. Two sets of rollers roll between the outer tracks of the outer ring and the inner tracks of the inner rings. The swivel mounting is constructed such that the outer ring with the first inner ring and the second inner ring forms one axial slide bearing at a time.

Abstract: A continuously variable transmission system comprises a continuously variable transmission having two pulley sets each with two discs defining a V-shaped groove, drive means-for varying the width of said groove and a belt extending between said-pulley sets in the grooves thereof, as well as a forward-reverse control connected to the shaft of one of the pulley sets and a clutch connected to said forward-reverse control, said pulley sets, forward-reverse control and clutch each being provided with a respective actuator. The actuators of the forward-reverse control and of the clutch are of an electromechanical type.

Abstract: A bearing ring includes a first ring part having a first peripheral surface forming a rolling body retaining track or a sliding surface and a second peripheral surface, and a concentrically arranged second ring part having first and second peripheral surfaces. The first and second ring parts are pressed together to plastically mold the second peripheral surface of the first ring part into the first peripheral surface of the second ring part through axial expansion. During manufacture, one tool grasps the first peripheral surface of the first ring part and presses it into a pre-determinable shape and another tool supports the second peripheral surface of the second ring part. The first ring part is pressed against the second ring part, with the contour of the second peripheral surface of the first ring part being plastically molded into the first peripheral surface of the second ring part through axial flow forming.
