摘要： The invention relates to a wheel end assembly for a vehicle, comprising a central wheel support member such as a spindle or a steering knuckle, and an outboard wheel end bearing arranged concentrically around the central wheel support member. The outboard wheel end bearing comprises roller elements accommodated between an inner race-forming part and an outer race-forming part surrounding the inner race-forming part. The inner race-forming part is configured to be supported by the central wheel support member. The central wheel support member comprises a first rotational lock portion. The inner race-forming part comprises a second rotational lock portion configured to engage with the first rotational lock portion to prevent the inner race-forming part from rotating relative to the central wheel support member. The invention also relates to a vehicle comprising such a wheel end assembly.

摘要： A main bearing assembly of a wind turbine includes at least one main bearing with a rotation axis and at least one bearing row in which a rotor shaft of the wind turbine is mounted. The main bearing assembly has at least one stationary bearing ring, a circulating bearing ring and rolling elements. A method of extending the service life or servicing the main bearing assembly includes rotating the stationary bearing ring about the rotation axis of the main bearing assembly. Alternatively, only a new stationary bearing ring, preferably with at least two bearing ring segments is installed instead of a damaged outer ring, in particular without further important bearing components such as the inner ring being exchanged.

摘要： A gantry assembly includes a rotor rotatable about a central axis, a stator fixed with respect to the axis and a bearing inner ring connected with the rotor and having an outer circumferential surface providing a least one inner raceway and two opposing axial end. A bearing outer ring is disposed about the inner ring and has an inner circumferential surface providing at least one outer raceway, first and second axial ends, an annular recess extending axially inwardly from the first axial end, and a plurality of threaded mounting holes extending axially-inwardly from the recess and spaced circumferentially about the central axis. An annular damper is disposed within the recess and a plurality of threaded fasteners each extend from the stator, through the damper and into a separate one of the plurality of threaded mounting holes to connect the bearing outer ring with the stator.

摘要： An assembly has a radial ball bearing including a bearing inner ring, and a rotatable shaft with a shaft end region with a bearing seat. The bearing seat has a shoulder on one side, on which the bearing inner ring of the radial ball bearing is seated for supporting the shaft. The bearing seat is shortened in the longitudinal direction relative to the radial ball bearing, and extends toward a height of the radial ball bearing. The bearing seat terminates at a distance (L) from an orthogonal projection from the proximalmost points of a distalmost row of balls onto the bearing seat surface such that L=k*D, wherein k is in a range between 0.7 and 0.5.

摘要： A rotational structure is configured such that a hollow portion, in which a base member is opposed to a rotational member, is formed around a shaft member. An encoder provided in the hollow portion includes a detection target member rotated together with one of the rotational member and the base member and having a physical quantity changing in a circumferential direction, and a detector capable of detecting the physical quantity of the detection target element and rotated together with the other of the rotational member and the base member.
