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 ().

Wind turbine with a rotor bearing having channels

A bearing arrangement may be employed in a rotor shaft of a wind turbine. The rotor shaft may transfer rotation of a hub with rotor blades to a generator. The bearing arrangement may include a hub-side rolling bearing and a generator-side rolling bearing. The hub-side rolling bearing may be configured as a radial roller bearing. The generator-side rolling bearing may be configured as a three-row roller rotary connection. The hub-side rolling bearing may include a closed cage with windows for guiding rolling elements. Rows of the closed cage may be separated by a central web. Further, at least one of the generator-side rolling bearing or the hub-side rolling bearing may comprise inductively hardened raceways.
