Abstract: Locking device for positive locking a rotor of a wind turbine, with a rotor shaft of a drive train rotatably mounted on a machine frame of the wind turbine, a locking disk and a locking bolt, the rotor shaft being non-rotatably connected with the locking disk, which has one or more through-openings for the engagement of the locking bolt, wherein the locking bolt can be substantially locked on the machine frame in a circumferential direction of the rotor shaft, and is arranged on the machine frame for displacement in substantially an axial direction of the rotor shaft, the locking bolt is constructed to be substantially rotationally symmetric about its center axis, in particular cylindrical-shaped, and is supported in a housing, wherein the housing is constructed with an inner hollow-cylindrical seat for receiving the locking bolt and an outer cylindrical shape with a center axis.
