A fluid film bearing, includes a first and second part, wherein the first part includes at least two annular sliding surfaces, wherein the second part includes a respective group of pads for each of the annular sliding surfaces, wherein a respective pad sliding surface of each pad in a respective group supports the respective annular sliding surface, wherein the pads of each group are distributed in the circumferential direction along the second part, wherein at least one pad of a selected one of the groups is arranged such that spacing of the pads in the selected group along the circumference is irregular and/or wherein the selected or a selected one of the groups includes two different types of pads and/or wherein the pads of the or a selected one of the groups are offset in the circumferential direction with respect to the pads of a further one of the groups.

Fluid film bearing, especially for a rotor hub in a wind turbine

A method for replacing a sliding pad of a rotational sliding bearing, wherein the bearing includes a plurality of sliding pads each supporting an annual rotatable part of the bearing on a stationary part of the bearing in an axial direction and/or a radial direction, including the steps: removing a load of the rotatable part from the sliding pad to be removed by releasing a force applied to the sliding pad and/or by applying a force to the rotatable part, removing the sliding pad in an axial and/or a radial direction, inserting a replacement sliding pad, supporting the rotatable part on the replacement sliding pad by applying a force to the replacement sliding pad and/or by removing the force applied to the rotatable part.

Method for replacing a sliding pad of a rotational sliding bearing, sliding bearing and wind turbine

Provided is a main bearing for a wind turbine, including a stationary ring and a rotating ring to be coupled to a rotor, whereby the main bearing is a fluid film bearing including several bearing units arranged at the stationary ring around the circumference on both sides of the rotating ring, for radially and axially bearing the rotating ring, and further including a load measurement arrangement for determining measurement data which are a measure for the load applied to or resting on at least one of the axial or radial bearing units.

Main bearing for a wind turbine

Provided is a fluid film bearing, especially for a rotor hub in a wind turbine, including an inner part that supports a rotating outer part, wherein the inner part includes multiple radial pads distributed along the outer circumference of the inner part, each of the radial pads having at least one radial pad sliding surface, wherein the radial pad sliding surfaces support at least one outer part sliding surface of the outer part in the radial direction.

Fluid film bearing and wind turbine

Provided is a fluid film bearing, for a rotor hub in a wind turbine, including a first and second part rotatably connected to each other, wherein the first part forms a first annular sliding surface that extends in the circumferential direction of the bearing along the first part, wherein the second part includes a support structure and first pads distributed along the circumference of the support structure, wherein a respective pad sliding surface of each of the first pads or of a first subgroup of the first pads supports the first annular sliding surface, wherein each first pad includes a mounting section that is mounted to a backside of the support structure, a contact section that is either forming the respective pad sliding surface or carrying a coating that forms the respective pad sliding surface and a connecting section that connects the contact section with the mounting section.
