In a housing that supports a rotating shaft via a rolling bearing which is subjected to predetermined position precompression, a wedge member, the radial thickness of which increases from the leading end towards the base end thereof, is inserted between the housing and the outer circumferential surface of the outer race of the rolling bearing and between the rotating shaft and the inner circumferential surface of an inner race of the rolling bearing, the wedge member being inserted from the leading end thereof along the radial direction of the rotating shaft. The wedge member is fixed by being fastened, ahead in the insertion direction, by bolts and nuts, so that precompression force along with predetermined position precompression is imparted to the rolling bearing.

A release bearing arrangement is provided for a piston of a clutch cylinder of a multi-plate clutch, which piston is axially movable along a shaft of a motor vehicle. The release bearing arrangement includes a release bearing for axial force transmission of an actuating force introduced by the piston to a transmission device of the multi-plate clutch. The release bearing has a first bearing plate, a second bearing plate and a plurality of rolling elements, the rolling elements being arranged so as to roll between the first bearing plate and the second bearing plate. The release bearing arrangement has a self-centering device for radial self-centering of the release bearing relative to the shaft and/or relative to the piston that is axially movable along the shaft.

A sensor arrangement for indirect detection of a torque of a rotatably mounted shaft includes a sensor with at least one sensor element arranged in the surroundings of a bearing of the shaft. The bearing is linked to a supporting structure. The sensor element is configured to detect a proportion of a bearing force acting in a predetermined direction. The torque of the shaft is configured to be calculated from the acting proportion of the bearing force. The sensor has at least one sensor body with an outer contour that supports a corresponding sensor element and is pressed into a receiving hole. The sensor element has a predetermined distance and a predetermined angle to the bearing.

A flywheel system comprises a flywheel rotor comprising a rotor disc and a rotor shaft and has a longitudinal axis extending centrally through the rotor disc and the rotor shaft. The system further comprises a journal assembly configured to facilitate rotation of the flywheel rotor. The journal assembly comprises a sleeve having an aperture extending therethrough from a first end to a second, opposite end, a rod at least partially disposed within the aperture of the sleeve, and a nut coupled to a portion of the rod. The rod has a length greater than the sleeve such that a portion of the rod extends axially beyond the first end of the sleeve. A method of forming the flywheel comprises coupling the rod to the rotor shaft and pulling the second end of the rod to tension the rod. The nut maintains the tension in the rod when coupled thereto.

A rotary valve including a housing with a removable housing cover, a rotor within the housing which is at least partially placeable outside the housing by detaching and displacing the housing cover away from the housing so as to enable access for cleaning or inspection of the rotary valve, wherein an end portion of a shaft of the rotor is mounted in a bearing assembly supported by the housing cover, which bearing assembly comprises a first bearing and a second bearing that are adjustable in position so as to maintain the shaft of the rotor in a level orientation with reference to the housing when the housing cover is moved away from the housing, wherein the first bearing and the second bearing are movable with respect to each other in a direction transversely to a longitudinal direction of the shaft.
