Description

technical field [0001] The invention belongs to the technical field of overhaul engineering for nuclear-level rotating equipment, and in particular relates to a centering device and method for a shaft coupling of nuclear-level rotating equipment. Background technique [0002] Coupling alignment of nuclear-grade rotating equipment in nuclear power plants is an indispensable maintenance technology. The alignment quality of the two shafts directly affects the vibration level and service life of the equipment. The coupling center is adjusted to the standard range. [0003] When performing the alignment work of the coupling of nuclear-level rotating equipment, the coupling alignment device had obvious shaking, resulting in a large swing in the percentage indication, and the reading was not accurate enough, which seriously affected the alignment quality, and the original device had many parts , the structure is more complicated, and the installation and use take a long time.
