Since the gap between the rotor and the stator of the generator is extremely small, in order to safely withdraw the rotor without colliding with the stator, it is necessary to reduce the installation of auxiliary equipment so as to smoothly withdraw the rotor.
The rotor of the large-sized generator is longer, the shaft diameter sliding block is matched with the small sliding block for use in the design of the rotor, and the shaft diameter sliding block enters the sliding plate to lift the exciting end rotor to pull through the small sliding block from the exciting end. Because the small sliding blocks can not be extracted due to the fact that the space between the generator rotor and the stator is small, a dummy shaft is required to be arranged on the steam end rotor to prevent the small sliding blocks from being lifted when the small sliding blocks can not be extracted.
The existing design cannot ensure that the small sliding block is smoothly pulled out from the excitation end, a long shaft needs to be installed to lift the steam end rotor, the step of pulling through the rotor is increased, the rotor safety is affected, and the maintenance time is wasted.
