Bearing arrangement for a wind turbine and wind turbine

A bearing arrangement for a wind turbine comprising:

• a bearing housing having a cylindrical seat with a circumferential curved inner surface;
• a drive shaft arranged within the bearing housing in an axial direction along a longitudinal axis of the bearing housing;
• a downwind bearing;
• and
• an upwind bearing, wherein the downwind bearing and the upwind bearing are arranged between the bearing housing and the drive shaft, further wherein the downwind bearing and/or the upwind bearing is a radial fluid bearing comprising multiple radial bearing bodies and multiple radial tiltable support structures secured to the multiple radial bearing bodies,
• wherein each one of a multiple of radial bearing pads is attached to a corresponding one of the multiple radial tiltable support structures and the multiple radial bearing pads are arranged about the drive shaft;
• wherein at least one curved interface plate is attached to at least one of the multiple radial bearing bodies on a surface of the at least one of the multiple radial bearing bodies facing the cylindrical seat of the bearing housing and opposite one of the multiple radial bearing pads, wherein the at least one curved interface plate includes a curved outer surface on a side of the at least one curved interface plate facing the cylindrical seat such that the curved outer surface has a curvature which corresponds to a curvature of the circumferential curved inner surface, and the at least one curved interface plate is arranged in contact with the cylindrical seat of the bearing housing.
