Abstract

CLEAN A wind turbine (100) with a rotor bearing (1) is proposed, wherein drainage chambers (7) on both sides of the rotor bearing (1) are connected to each other via a plurality of channels (5) traversing an outer ring (2) of the rotor bearing (1), which are distributed over the circumference of the outer ring (2) and that an axis (A) of the rotor bearing (1) is arranged at an angle in the range of 2° to 100 to the horizontal line (H) for promoting a flow of leakage oil through the channels (5).
