Abstract

PURPOSE: To improve the tightness between a side disk and blades by coupling the projections of hollow blades, formed to a specified shape by providing the blade tip with an appropriate amount of twist, after inserting the projections into the fitting holes of the side disk and a core disk respectively, as well as by draw-forming the side disk.
CONSTITUTION: Blades 7 are formed to a three-dimensional shape having a thickness by twist-forming the blade tip and the projections 7a prepared on the both ends of the blades 7 are inserted into the fitting holes 7b of a core disk 5 and a side disk 6 respectively and are fixed together by bending. Furthermore, the side disk 6 and the blades 7 are fixed tightly by draw-forming, while being pressed, along the curve of the portion A of the blade 7 to the arrow direction. Thus, the performance characteristics of a fan can be maintained and noise can be reduced by removing the clearances between each end of two blade plates, forming the hollow blade, and the side disk 6 for keeping tight fixing.
