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

A tapered roller bearing may comprise an inner ring, an outer ring, and two rows of tapered rollers that are arranged in an O-arrangement between the inner ring and the outer ring. The inner ring may extend in an axial direction over a greater length than the outer ring, and a gap between the inner ring and the outer ring on at least one side of the tapered roller bearing may be sealed by a sealing assembly. The sealing assembly may comprise a main seal that is attached to the inner ring in a rotationally fixed manner, as well as a seal race ring that is attached to the outer ring in a rotationally fixed manner. The seal race ring may form a seal raceway for the main seal.
