Axial seal for a generator rotor of a wind turbine

A sealing arrangement of a wind turbine comprising an axial seal, a stationary member and a generator rotor for sealing a gap between the stationary member and the generator rotor;

• wherein the stationary member is arranged between a lubricant chamber and an air chamber;
• wherein the generator rotor is configured to rotate about a rotational axis;
• wherein the seal is arranged at an end of the stationary member,
• wherein the seal comprises a first lip configured to contact the generator rotor;
• wherein the first lip is configured to allow a leakage of lubricant at the contact between the first lip and the generator rotor;
• wherein the seal further comprises a second lip arranged radially outwards with respect of the first lip and the rotational axis;
• and
• wherein the second lip is at least partially lubricated by the leakage of lubricant at the contact between the first lip and the generator rotor.
