FIELD: machine building.
SUBSTANCE: rotor of a centrifugal compressor comprises a shaft with an impeller mounted on it and having an annular cavity in the hub which divides the hub into the outer and inner rings and on the one side is limited by a circular partition connecting the inner and the outer rings and being made on the side of flow inlet to the impeller. Mounting surfaces in the impeller and at the shaft are conical and are located on the outer surface of the inner ring and the inner boring of the shaft end respectively. The shaft and the impeller interact with each other additionally by means of a spline joint.
EFFECT: invention allows for the increased reliability of the connection of the impeller to the shaft of a centrifugal compressor rotor along with simultaneous simplification of the rotor manufacturing and assembly process.
