Zusammenfassung:The invention discloses a method for centering a roundness measuring frame of a vertical shaft umbrella type hydro-generator rotor, and the method comprises the steps: measuring a lower guide bearinginstallation center during turning, and determining the offset distance of the rotation center of a lower guide bearing in a certain direction relative to the lower guide bearing installation center;measuring and calculating the offset distance of an upper flange of the generator rotor relative to a lower flange of the generator rotor in a certain direction; superposing the obtained results to obtain the offset distance offset X of the upper flange of the generator rotor relative to the rotation center of the lower guide bearing in one direction M during operation; and finally, by taking thecenter of the flange on the generator rotor as a reference, when the rotor roundness measurement frame is mounted, moving X towards the -M direction to complete reference adjustment of the rotor roundness measurement frame.
