Abstract

PURPOSE: To improve the rigidity between blades and a side disk and the total stiffness of an impeller by forming tight contact between the blades and the side disk while the projections of the blades are blended by a spinning roller after the impeller is temporarily assembled in a body by inserting the projections of the blades into the holes fitting to the projections prepared for both the side disk and a core disk.
CONSTITUTION: As shown in the drawing, the projections 5 prepared on both sides of blades 4 are inserted into the predetermined fitting holes of a core disk 2 and a side 3 respectively for temporary assembling. Next, the temporarily assembled impeller is fitted onto a fixture 10, integrated with a spindle 7 and driven by a motor (not shown in the drawing), and is pushed to the fixture 10 by a tail rod 8, thereafter the temporarily assembled impeller, while being rotated, is pressed for bending by a spinning roller 9 copying the profile of the side disk 3 or the core disk 2. Thus, the tightness of the contact surfaces between the blades 4 and the side disk 3 or the core disk 2, as well as the total rigidity of the impeller are improved.
