Abstract
A wind turbine comprising a tower (2) with a tower wall and having at least one nacelle (3) mounted thereon, and a yaw system (1) interconnecting the tower (2) and at least one nacelle (3) is disclosed. The yaw system (1) comprises a yaw claw (4) comprising an upper radially extending part (5), a lower radially extending part (6) and an axially extending part (7) interconnecting the upper radially extending part (5) and the lower radially extending part (6), thereby defining a space. A sliding bearing connection with at least two axial sliding surfaces (9, 10) and at least one radial sliding surface (11) is arranged between the yaw claw (4) and a flange (8) arranged in the space defined by the yaw claw (4). At least one yaw drive (13) comprising a toothed gear (14) is arranged in meshing connection with a toothed yaw ring (12). The axially extending part (7) of the yaw claw (4) and the meshing connection between the toothed gear (14) and the toothed yaw ring (12) are arranged at the same side of the tower wall.
