A non-locating bearing assembly includes a bearing unit configured to support a rotating component relative to a stationary component, the bearing unit including a stationary bearing ring and a rotatable bearing ring that are rotatable with respect to each other. The rotatable bearing ring is fixedly connectable to the rotating component, and the stationary bearing ring is mountable in the stationary component in a rotationally fixed but axially displaceable manner. A connector is provided between the stationary bearing ring and the stationary component to connect the bearing ring to the stationary component in an axially displaceable but substantially rotationally fixed manner, and the connection is provided by a combination of a friction fit and an interference fit acting in the circumferential direction.

An aircraft is described comprising: a support element; a shaft rotating about an axis; a pair of oblique rolling bearings mounted so as to couple the shaft to the support element (rotatingly about the axis; the rolling bearings comprising: respective first races cooperating radially in contact with a first component (defined by one from the support element and the shaft; respective second races cooperating radially in contact with a second component (defined by the other from the support element and the shaft; and respective pluralities of rolling elements adapted to roll on the first and second races; the aircraft further comprises a pair of preloaded elastic members, which couple the first races to the first component respectively, axially and in an elastically yielding manner.

A rotating machine including a thrust bearing configured to receive an axial thrust exerted by a rotor. The thrust bearing may be configured to transfer the axial thrust from the rotor to a housing or other structural component of the rotating machine using a plurality of ball bearings. The rotating machine includes a magnetic apparatus configured to cause the rotating machine to exert an axial force on the thrust bearing in the direction of the axial thrust of the rotor, such that the magnetic apparatus loads the ball bearings in the direction of the axial thrust. The magnetic apparatus may be configured to generate a magnetic field causing a first magnetic component of the magnetic apparatus to repel or attract a second magnetic component of the apparatus. The first magnetic component may be configured to rotate relative to the second magnetic component.

An electric machine for use within the powertrain of a hybrid or fully electric motor vehicle including a stator and a rotor which is separated from the stator by an air gap, said stator and rotor being received in an engine housing. The rotor is rotatably mounted relative to the stator by means of two axially spaced rolling bearings, and at least one of the rolling bearings is axially biased by a spring element which is supported against the motor housing in the axial direction and lies against the rolling bearing. The biased rolling bearing has an inner ring and an outer ring, between which a plurality of rolling bodies are received in a rollable manner, the inner ring is rotationally fixed to the rotor via a first bearing seat, and the outer ring is rotationally fixed to the engine housing via a second bearing seat. The spring element is arranged on the first bearing seat and/or second bearing seat so as to be secured in the axial direction in a form-fitting manner.

A king pin assembly for rotatably connecting a steering knuckle with an axle member may have a first king pin. The assembly may also have a first member with a first recess for receiving the first king pin. The first member may have a steering knuckle or an axle member. A portion of the first member that may enclose the first recess may have a female thread. The first king pin may have a male thread engaged with or configured to be engaged with the female thread enclosing the first recess.

A bearing assembly includes a first locating bearing and a second locating bearing configured to be mounted on a shaft. The first locating bearing includes a two-part outer ring formed from a radially inward outer ring and a radially outward outer ring, and a diameter of the inward outer ring is smaller than a diameter of the outward outer ring.

Systems and method for cooling and lubricating power transmission systems include providing oil to an oil tube and then to a rotor shaft via the oil tube. Oil may also be provided through at least one channel defined in an end of the oil tube inserted into an annular region of the rotor shaft, through at least one channel defined in an end of the gear shaft and between the end and a shoulder of the rotor shaft and through at least one channel defined in side surface of the rotor shaft in a region of rotor shaft inserted into the gear shaft. Such systems and method can also include providing oil a fluid passageway in a bearing shim plate via an inlet tube. Oil may also be provided through a radial gap adjacent a bearing shim plate outlet and chamber defined in the bearing shim plate.

A motor adjustment drive for a vehicle steering column includes a threaded spindle with an axis. The threaded spindle engages a spindle nut. A drive unit and a gear wheel which is connected to the spindle nut or the threaded spindle for rotation therewith is driveable to rotate by the drive unit and is rotatably mounted in a bearing housing between two outer bearing rings that are axially supported at the bearing housing. The outer bearing rings each have, on their sides facing one another, a circumferential outer bearing face that is coaxial to the axis. Each outer bearing face lays opposite a bearing face embodied on the end side at the gear wheel. An outer bearing ring is axially resiliently supported at the bearing housing via an elastic element, which exerts an axial force that biases the two outer bearing rings toward each other.

A bearing assembly (1) for preload measurement, having at least one rotary element (2, 3), wherein the at least one rotary element (2, 3) includes a radial (4) and/or axial receptacle (5) for a rolling bearing (6), wherein the at least one rotary element (2, 3) includes at least one measurement device (7, 8) in the region of the receptacle (4, 5) for measuring the rolling bearing preload, and wherein the at least one measurement device (7, 8) is located inside the at least one rotary element (2, 3).
