The invention relates to a tilting-pad bearing (7), comprising: a sleeve (15); a plurality of tilting pads (9); and a frame (8), in which the tilting pads (9) are held.

A wind power installation comprising one or more rotor blades, a rotor hub to which the rotor blade or blades are mounted, and a generator for generating electrical power, wherein the generator has a generator stator and a generator rotor which is non-rotatably connected to the rotor hub and which is rotatable about an axis, wherein the rotor hub and the generator rotor have a common main bearing system or means which is subdivided into two bearing portions which are spaced from each other in the direction of the axis, wherein in that the first bearing portion has a first radial plain bearing and a first axial plain bearing and the second bearing portion has a second radial plain bearing and a second axial plain bearing.

The invention relates to a wind turbine gearbox (8), in particular a planetary gearbox, having at least one gear (12) mounted on an axle (15), for which purpose a sliding layer (20) is arranged between the gear (12) and the axle (15), said sliding layer (20) being sprayed directly onto the axle (15) or, with intermediate arrangement of at least one further layer (21), onto the further layer (21) by means of a thermal spaying method.

A spur gear arrangement includes a spur gear, and two flange bushings configured to rotatably support the spur gear on a shaft, with each flange bushing including a flange. A lubricating film is provided between an inner side of the spur gear and each of the flange bushings. Two supporting bodies are arranged on the shaft, with the flange bushings being respectively arranged with their flange on the supporting bodies for axially bracing the spur gear.

A bearing element has at least one inner ring element and at least one outer ring element, wherein, between the inner ring element and the outer ring element, a sliding bearing system is disposed that is formed by at least two sliding bearings. The sliding bearings have a sliding face, which cooperates with a running face of the opposite ring element. In the new condition of the sliding bearing, the sliding face of the sliding bearing, viewed in cross section, has at least one first sub-portion and one second sub-portion, wherein a tangent constructed on the first sub-portion is disposed at a first angle relative to the central longitudinal axis and a tangent constructed on the second sub-portion is disposed at a second angle relative to the central longitudinal axis, wherein the first angle has a magnitude different from that of the second angle.

Yaw bearing arrangement for a wind turbine, comprising a yaw bearing with a yaw ring and radial adjustment acting on the inner radial lateral surface of the yaw ring, the radial adjustment comprising at least a housing, at least one sliding pad and one or more threaded adjustment bolts arranged in threaded housing bores and connected with the sliding pad for a radial adjustment of the sliding pad towards the lateral surface and axial bores for accommodating fixation bolts, wherein the housing is a ring or a ring segment with a plurality of radial, at least partially threaded bores, each radial bore accommodating a radial sliding unit comprising radial sliding pad and a threaded radial adjustment bolt for radial moving the sliding pad.

A plain bearing for a steering spindle of a steering column for a motor vehicle. The bearing includes an inner ring with an axially continuous bearing opening for slidably receiving the steering spindle. A prestressing element is configured to exert a prestressing force on the inner ring to clamp the inner ring on the steering spindle and thereby to assign a defined, uniform braking torque.
