Abstract:
Provided is a bearing arrangement for a wind turbine including a bearing housing and a drive shaft, whereby the drive shaft is arranged within the bearing housing in an axial direction along a longitudinal axis of the bearing housing. The bearing arrangement further includes a downwind bearing and an upwind bearing, whereby the downwind bearing and the upwind bearing are arranged between the bearing housing and the drive shaft. The bearing housing includes a drain outlet arranged in a bottom part of the bearing housing, the bottom part of the bearing housing being located underneath the drive shaft in a direction of gravity, whereby at least one inner side of the bottom part of the bearing housing is arranged so as to form a funnel, whereby the drain outlet is an opening of the formed funnel.
