Method and apparatus for changing a gearbox of a wind turbine

摘要

The method is for the changeout of a transmission (4) of a wind power plant. The rotor shaft (5) during the transmission changeout is supported on the machine frame (2) so that during the changeout the rotor remains on the rotor shaft. Support is provided by a yoke (11) which directly before the transmission changeout is mounted between the rotor shaft and machine frame and then removed again after the changeout. Independent claims are also included for the following: (A) a device for the execution of maintenance work on the drive train of a wind power plant, especially for the changeout of the transmission; (B) a yoke for support of the rotor of a wind power plant during a transmission changeout; and (C) a use for a yoke which is to support the rotor of a wind power plant during a transmission changeout.
