The complete equipment of the ship generator set consists of a diesel engine, a generator and a shared base, wherein the diesel engine and the generator are subjected to centering adjustment in the manufacturing stage, and the service life of relevant parts of the generator (such as a crankshaft, a bearing bush, a generator shaft, an elastic coupling and the like) is directly influenced by the centering condition. In order to ensure accurate centering of the ship generator set, factors influencing centering data need to be comprehensively detected in the centering process. The method adopted at present is to mount one magnetic meter on the outer circle surface of the flywheel to measure the runout of the outer circle of the flange of the generator, mount the other magnetic meter on the end surface of the flywheel to measure the runout of the end surface of the flange of the generator, further detect the centering data, see whether the centering data meet the centering requirement, and correspondingly adjust the centering data until the centering data meet the requirement when the centering data do not meet the centering requirement.

In addition, the outer circle size and the end face size of the flange plate of the flywheel and the generator meet the requirements of drawing, and the cutter is worn in the machining process according to the machining principle, so that the same part is formed.
In view of the above, there is a need for improvements.
