A wind turbine includes a nacelle with a main bearing tilted with its rotation axis towards the horizontal axis and including an inner and outer ring, wherein the main bearing is a slide bearing and the inner ring is stationary while the outer ring rotates, with the main bearing being lubricated, and with the outer ring including a first and a second sealing means, wherein the first sealing means is due to the tilt of the main bearing lower than the second sealing means, wherein a stationary leakage lubrication fluid collection means is provided adapted for collecting lubrication fluid, wherein the outer ring is provided with one or more axial bores connecting a leakage lubrication fluid collection area to the leakage lubrication fluid collection means and wherein each sealing means includes a groove accommodating a sealing element and a sealing element carrier ring.

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 ().
