Abstract: Provided is a thrust bearing for a wind turbine including a thrust collar rotatable around a longitudinal axis of the thrust bearing and having a thrust surface transversally oriented with respect to longitudinal axis, a support structure fixed with respect to the longitudinal axis of the thrust bearing, a bearing pad contacting the thrust surface of the thrust collar and movable on a pad seat provided on the support structure, a spring element interposed between the bearing pad and the support structure.

Abstract: A wind turbine, including a support structure and a thrust bearing having a bearing pad which includes a piston and which is movably connected to the support structure, a spring element which is configured to resiliently support the bearing pad relative to the support structure, wherein a pad portion of the bearing pad and/or the bearing pad itself is configured to tilt and to move translationally relative to the support structure, and wherein a gap is provided between the piston and the support structure. The piston limits the movement of the bearing pad. Thus, reliable and well defined movement limits are provided. Furthermore, a broad spectrum of spring parameters is available since the movement may be restricted by the piston and not necessarily be the spring element.

Abstract: Provided is a wind turbine, including a hub, a shaft which is connected to the hub, a bearing housing, in which the shaft is supported rotatable, a fluid bearing which supports the shaft in the bearing housing, wherein the fluid bearing is arranged at a proximal end of the shaft, wherein the proximal end of the shaft is positioned proximal to the hub, and a roller bearing which also supports the shaft in the bearing housing, wherein the roller bearing is arranged at a distal end of the shaft, and wherein the distal end of the shaft is positioned distal to the hub. One advantage of the wind turbine is that compared to roller bearings, the fluid bearing provides a bearing type with high load capacity and scalability to even large wind turbines.

Abstract: A method for changing a bearing component of a main bearing of a wind turbine, with the bearing component directly bearing a rotating shaft, characterised in that the bearing component being unloaded by mechanically moving the shaft is axially moved from or into its mounting position by means of a replacement tool device is provided.
