Abstract
PURPOSE: To contrive to lower the manufacturing cost of an impeller of the type in which its blades are fixed between shrouds by means of resistance caulking, by enabling to produce impellers having different characteristics from the same blades and parts associated therewith by changing the direction of installation of the blades while using the parts concerned in common.
CONSTITUTION: Caulking holes aWc formed in a shroud 1 are positioned such that they stand in a symmetrical relationship to each other with respect to the center line A-B. Similarly, caulking projections a'Wc' for a blade 3 to be fixed between shrouds are positioned in a symmetrical relationship with respect to the center line A'-B'. Further, the length l2 from the projection a' to one end face 3a of the blade 3 is made different from that l1 from the projection c' to the other end face 3c. With such an arrangement, it is enabled to install the blade 3 in two directions selectively and therefore to obtain impellers having different characteristics.
