Abstract RU 2080492 C1

FIELD: manufacture of compressors. SUBSTANCE: self-centering is effected during making seats in disks 1 and 2 in form of circular groove 5; blades 3 are provided with beads 4 whose circumferential length is equal to pitch of blades 3. After mounting blades 3 in groove 5 of drive disk 1, cover disk 2 is mounted on free end faces of blades 3; ends of beads are in contact over entire length of circular grooves 5. Then parts thus assembled are secured by beading or pressing the edges of disks 1 and 2; control of dynamic balancing is accomplished after securing the parts. EFFECT: enhanced efficiency. 2 dwg
