Megawatt-level ultra-high-speed full-circle laminated rotor structure

The utility model discloses a megawatt ultra-high-speed full-circle laminated rotor structure, which comprises a rotor core, the rotor core is formed by laminating full-circle inner-hole-free silicon steel sheets, end rings are assembled at the two ends of the rotor core, half shafts with flanges are assembled at the outer ends of the end rings, and the rotor core, the end rings and the half shafts with the flanges are tensioned through tensioning screws to form a whole rotor. The outer end face of the half shaft is sleeved with a sealing ring. The rotor iron core is formed by laminating the whole-circle inner-hole-free silicon steel sheets, the end rings are assembled at the two ends of the rotor iron core, the half shafts with the flanges are assembled at the outer ends of the end rings, and the whole rotor is formed by tensioning the rotor iron core, the end rings and the half shafts with the flanges through the tensioning screws. And the critical rotating speed requirement of the rotor of the ultra-high-s
