A sealing arrangement of a wind turbine is provided including an axial seal, a stationary member and a generator rotor for sealing a gap between the stationary member and the generator rotor. Accordingly, the stationary member is arranged between a lubricant chamber and an air chamber and the generator rotor is configured to rotate about a rotational axis, wherein the seal is arranged at an end of the stationary member. The seal includes a first lip configured to contact the generator rotor and the first lip is configured to allow a leakage of lubricant at the contact between the first lip and the generator rotor. The seal further includes a second lip arranged radially outwards with respect of the first lip and the rotational axis.

Axial seal for a generator rotor of a wind turbine

Provided is a bearing unit for a rotor unit of a wind turbine, including a first bearing ring, a second bearing ring, a plurality of rolling elements and a sealing member including a sealing member base portion, a first sealing member tip portion and a second sealing member tip portion, wherein the first sealing member tip portion abuts a first wall of the first bearing ring and the second sealing member tip portion abuts a second wall of the bearing unit, wherein the sealing member is configured and arranged such that a first contact pressure between the first sealing member tip portion) and the first wall is transmitted through the sealing member to the second sealing member tip portion to increase a second contact pressure between the second sealing member tip portion and the second wall. Also provided is a wind turbine.
