Claims

[Scope of utility model registration request]

In a turbine rotor assembled by stacking three or more disks consisting of an intermediate disk and disks on both sides of the intermediate disk in the axial direction, the intermediate disk is composed of a plurality of divided pieces in the radial direction, Flanges are provided on both sides of the intermediate disk, and a tapered recess is formed on the outer surface of the flange, and the disks on both sides of the intermediate disk have outwardly expanding tapers formed on opposing surfaces, and a taper is formed on the outer surface of the intermediate disk. cutting out a fan-shaped recess for fitting the divided pieces into the section, and inserting each of the divided pieces from the fan-shaped recess and turning them in the circumferential direction to sequentially fit them;
A turbine rotor assembly characterized in that at least a portion of the divided piece is prevented from rotating so that it is located in a portion other than the fan-shaped recess.
