Abstract
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.
