FIELD: mechanical engineering; air blowers, compressors and outer vane machines.
SUBSTANCE: invention relates to electric compressors, turbocompressors for supercharging internal combustion engines, air blowers and other vane machines. Proposed high-speed rotor of blower provides practically complete elimination of rotor unbalance owing to provision of minimum tolerable deformation of shaft when rotor parts pack is tightened by nut, thanks to which vibration and noise of turbocompressor in operation are considerably reduced, service life of bearings is increased and rubbing of impeller or turbine of compressor against base members is prevented which improves operating capabilities and reduces energy consumption. For this purpose, according to first design version, rotor is furnished with plates, each placed between end face of compressor impeller bushing and nut. Said plate has concave spherical surface at one side adjoining convex spherical surface of nut, and at other side, flat surface adjoining flat end face of bushing of compressor impeller. Ring groove is made on each bushing of compressor impeller between blades and end face of compressor impeller bushing. According to second version, ring groove is made on each bushing of compressor impeller between blades and end face of compressor impeller bushing provided with concave spherical surface adjoining convex spherical surface of nut.
EFFECT: improved operating capabilities, reduced energy consumption.
