FIELD: engines and pumps.
SUBSTANCE: threaded connection is arranged in an annular air cavity on outer side of a cylindrical connection strap attaching the discs and on inner side of the rotor annular slot. The threaded connection bar shank is provided with a cylindrical axial projection. Ratio of the height of the threaded connection nut to axial width of annular slot of the rotor is 1.1…2, and ratio of inner diameter of the nut thread to outer diameter of cylindrical projection is 1.01…1.5.
EFFECT: invention allows improving the compressor rotor reliability.
