FIELD: machine building.
SUBSTANCE: rotor for a bladed machine with an axial flow includes several rotary discs located in a pile. Discs are pressed to each other in axial direction by means of at least one tension bolt, and each disc has outer diameter. At least two rotary discs have outer diameter that is smaller than that of adjacent rotary discs. Available difference of diameters is compensated by means of a drum enveloping rotary discs annularly with smaller diameter. Drum encloses rotary discs with smaller diameter throughout their axial length and has on its inner surface an endless enveloping partition that is adjacent in axial direction between enveloped rotary discs with smaller diameter. Besides, objects of this invention are a compressor containing the above described rotor and a gas turbine containing such a compressor.
EFFECT: invention allows enlarging the service life of rotor of bladed machine.
