Abstract

The present invention discloses a rotor turning device for a wind turbine generator which can be used without having to modify the existing wind turbine generator, and a method for turning the rotor. A rotor turning device (50) comprises first members (52 (52A, 52B)) serving as a fixing portion, which are provided on the inner peripheral side of the rotor turning device and fixed to a coupling hub (70), second members (62 (62A, 62B)) serving as a portion to be operated, which are provided on the outer peripheral side of the rotor turning device and to which operation force for rotating the rotating shaft of a wind power generation device (1) is inputted. A pair of first members (52 (52A, 52B)) are held and fixed to the coupling hub (70) of a coupling (16), and the second members (62 (62A, 62B)) attached to the first members (52) are shaped into a handle.

Description

technical field [0001] The invention relates to a rotor turning device and a rotor turning method for a wind turbine generator. In particular, the present invention relates to a rotor turning device for turning a rotating shaft of a wind turbine generator which increases the rotational speed of the rotor head transmitted to the generator through a gearbox, and to a method of turning the rotor . Background technique [0002] In recent years, from the viewpoint of protecting the global environment, it has become common to generate renewable energy using wind turbine generators. [0003] Typically, a wind turbine generator includes a rotor head equipped with blades, a nacelle housing a power transmission system and a generator, and a tower supporting the nacelle. The power transfer system is used to transfer torque from the rotor head side to the generator side and typically includes a gearbox to increase the rotational speed of the rotor head to the generator. [0004] When...
