Assembling and disassembling device for generator rotor

The utility model provides an assembling and disassembling device for a generator rotor. The generator rotor is a turbonator rotor which is arranged horizontally. The assembling and disassembling device comprises a conveying dolly and a driving apparatus thereof, the upper surface of the conveying dolly supports a turbonator rotor retaining ring which is heated individually; and a rectilinear motion track is arranged along the axial direction of the turbonator rotor on a working surface, and the conveying dolly is drove by the driving apparatus to move along the rectilinear motion track. The assembling and disassembling device for the generator rotor overcomes that the retaining ring and a rotor body are not concentric and a thrust is nonuniform when the retaining ring is assembled and disassembled, and the quality and efficiency of sleeving the retaining ring are raised, operators' labor intensity is reduced, and dangerous accidents are effectively prevented.
