Abstract

PURPOSE: To prevent the generation of vibration and noise and secure aerodynamical performance by locating a blade where the inside edge of a blade is extended toward within the inside diameter of the blade to eradicate pitch errors and inclination.
CONSTITUTION: A centrifugal fan 8 is composed of a blade main plate 14, a blade side plate 15 and blades 16, which are integrated by claws 17 from blades 16 clamping through square holes 17 of each blade. Inside edges 19 of blades 16 are extended so that its inside diamter D1 becomes smaller than the inside diameter D0 of a blade side plate 15, and their height is formed to be lower toward their end edge. As to the assemblage, after the inside edges 19 of blades 16 are held at the specified position by inserting a plier from inside the side plate 15, claws 17 are clamped tightly to eliminate pitch errors or inclination of blades 16 which are caused by loose fitting of claws 17 are square holes 18.
