  • Patent number: 9284949
    Abstract: To facilitate adjusting a bearing arrangement, particularly in a wind turbine, for different operating situations, the bearing arrangement has an adjusting device with which the bearing preload can be adjusted starting from a base preload. This can allow, for example signs of wear to be compensated, manufacturing tolerances or design inaccuracies to be corrected and in particular current loading states to be addressed. This design avoids the otherwise usual overdimensioning of the bearing arrangement, thereby increasing the efficiency of the wind turbine as well as the service life of the bearing arrangement.
