FIELD: engines and pumps.
SUBSTANCE: invention relates to gas turbines, particularly, to gas turbine rotors. Gas turbine rotor comprises wheel tapered flange, shaft tapered flange and circular flanges of labyrinths locked by bolt joints. Said circular flanges of labyrinths have identical recesses. Said recesses are arranged so that bolt joints locking the wheel tapered flange, shaft tapered flange and circular flanges of labyrinths alternate with aforesaid bolt joints. Wheel tapered flange has outer and inner axial circular ribs covering mating the circular rib of the shaft tapered flange. Nits of all bolt joints are arranged on the side of wheel tapered flange.
EFFECT: simplified design, decreased weight and higher reliability.
