The long U-shaped bolt adjustment and assembly holes 2 are connected to one end of the generator rotor coupling. Due to the different models and specifications of the generator rotor, the function of the long U-shaped bolt adjustment and assembly holes 2 is to slide and adjust according to the specifications of the generator rotor coupling.
