The invention relates to a bearing assembly for an exhaust gas turbocharger for rotatably supporting a rotor shaft on a bearing housing, having at least one bearing outer ring of a radial bearing, which at least one bearing outer ring is placed in a bearing bore of the bearing housing and consists of at least one part, and at least one securing element, which consists of at least one part and by which the bearing outer ring is axially fastened in relation to the bearing housing. In order to simplify the assembly of a corresponding bearing assembly and to reduce the production costs thereof, at least one circumferential groove, according to the invention, is arranged on an outer lateral surface of a compressor-side end section of the bearing outer ring, in which at least one groove the securing element engages, and the securing element is arranged outside of the bearing bore on the compressor side and is supported at least indirectly on a compressor-side end of the bearing housing.

A gear unit for a motor vehicle having a drive shaft extending axially and mounted rotatably, and a worm gear shaft which cooperates with a worm gear wheel. A torque-transmitting coupling connects the drive shaft to one end of the worm gear shaft with the other end supported by a bearing. A pretension element loads the bearing and correspondingly the worm gear shaft so the worm gear shaft is biased or pressed against the worm gear wheel. The torque-transmitting coupling provides a suitable connection between the drive shaft and worm gear shaft.

A gear unit for a motor vehicle including an axially extending worm gear shaft, rotatable about a rotation axis, and cooperating with a worm gear wheel. The worm gear shaft supported, on one side of the worm gear wheel, through a first rotary bearing, on a housing and on the other side by of the worm gear wheel by a second rotary bearing loaded such that the worm gear shaft is pretensioned against the worm gear wheel. To optimize worm gear shaft and worm gear wheel engagement the first rotary bearing pivots or tilts relative to the housing, with deformation of at least one return element about a tilt axis perpendicular to the rotation axis. The return elements supporting the first rotary bearing on the housing in the axial and radial direction.

A rotary milking platform (1) comprises a platform (3) having a circular carrier beam (7) secured to the underside of the platform (3). The carrier beam (7) is supported on a plurality of support elements (10), each of which comprise a freely rotatable roller (35) which is configured to rollably engage an under surface (38) of the carrier beam (7). Each support element (10) comprises an anchor plate (27) adjustably mounted on a corresponding ground engaging element (20) which is secured to the ground. A carrier plate (40) is carried on four guide bolts (50) extending upwardly from the anchor plate (27). Side members (41) extending downwardly from the carrier plate (40) rotatably carry the roller (35). Compression springs (59) acting between abutment washers (55) secured to the guide bolts (50) and the carrier plate (40) urge the carrier plate (40) against heads (53) of the guide bolts (50). The compression springs (59) accommodate downward and upward movement of the roller (35) in order to accommodate rising and falling of the under surface (38) of the beam (7). The compression springs (59) permit tilting movement of the roller (35) about a tilt axis (61) which extends in the direction of motion of the beam (7) in order to facilitate tilting of the roller (35) to follow any non-horizontality of the under surface (38) of the beam (7). The tilt axis is located just below a line of contact (67) of the roller (35) with the under surface (38) of the beam (7) to minimise lateral movement of the roller relative to the beam (7) as the roller (35) tilts about the tilt axis.

A bearing support system includes a bearing disposed within a bearing housing. A bearing damper is disposed around the bearing and includes one or more knitted mesh pads. A compression ring is positioned to be movable relative to the bearing housing and to apply a compression to the bearing damper that results in a change in at least one of a length and a wall thickness of each knitted wire mesh pad and a corresponding change in the stiffness and bearing of the damper. The system supports rotation of a shaft and may include one or more sensors to measure vibrations in the shaft and a controller to control movement of the compression ring in response to the mechanical vibrations.

A joint mechanism comprises at least one body, at least one first roller and at least one second roller mutually positioned on said body and is configured to move any one of said first roller and second roller towards the other so as to allow a beam used particularly in vibration isolation mechanisms to translate along at least one first axis. The body has at least one first part and at least one second part essentially adjacent to each other and said first part and said second part are engaged by means of at least one first flexible element in a manner such that they allow at least partial movement with respect to each other, so as to allow said beam to be rotated at least partially around at least one rotating point in the direction of at least one second axis.

Systems and methods include providing a tolerance ring with a friction enhancement feature on at least one surface of the tolerance ring to increase at least one friction-related property of the tolerance ring. The friction enhancement feature provides the tolerance ring with an increased retention force while providing an optimum radial force that allows a component secured by the tolerance ring to move freely while reducing or altogether preventing axial movement of the component.

A wheel hub assembly for motor vehicles, having a rotatable hub, a bearing unit in turn comprising a radially outer ring, a radially inner ring and a plurality of rolling bodies. The axial interface between the wheel hub assembly and a knuckle of a motor vehicle suspension provides at least one piezoelectric spacer configured to detect first mechanical vibrations coming from the components of the wheel hub assembly and to implement corrective action consisting of second mechanical vibrations of almost equal amplitude but with opposite direction and phase, so that the resultant of the first and second mechanical vibrations is close to zero.

A bearing assembly for supporting rotation of a shaft in a turbocharger includes an inner race extending along an axis. The inner race is configured to be coupled to the shaft. The bearing assembly also includes an outer race spaced radially from the inner race and a cage disposed radially between the inner race and the outer race. The bearing assembly further includes a rolling element disposed radially between the outer race and the inner race. The rolling element is disposed within the cage for supporting rotation of the shaft. The outer race defines a lubricant passageway configured to direct lubricant toward the cage.
