Abstract

A wind turbine includes a rotor shaft. The rotor shaft is mounted via a bearing assembly having a first bearing ring and a second bearing ring mounted to rotate in relation to the first bearing ring. A hydrostatically supported first friction bearing segment is disposed on the first bearing ring and interacts with a first friction face that is disposed on the second bearing ring. The first friction bearing segment is received in a receptacle pocket of the first bearing ring such that a first compression chamber is formed between the first bearing ring and the first friction bearing segment. The first friction bearing segment is configured such that a second compression chamber is formed between the first friction bearing segment and the second bearing ring, wherein the first compression chamber and the second compression chamber are connected by a duct that runs through the first friction bearing segment.
