Abstract
PURPOSE: To make possible integral molding due to die casting or the like and to improve productivity in manufacturing a diagonal flow fan vane wheel by a method wherein a plurality of vanes to generate diagonal flow acceleration are provided on the surface of the peripheral wall of a cylindrical hub and the rear parts of each vane are provided so that the whole body can be seen from the upper stream side.
CONSTITUTION: A plurality of vanes 2, 2... to generate diagonal flow acceleration are provided on the surface 1a of a peripheral wall of the hub 1. Through the shape of each vane 2 has a three-dimensional curve based on a free disign, the vane 2 is made up so that the whole body can be seen from the upper stream side. Therefore, although a vane wheel A1 is made up of vanes 2 having a fixed angle in the axial direction, the hub 1 has a cylindrical form and accordingly, when the whole back surface part 2a of each vane can be seen from the upper stream side, an integral molding can be conducted by an axial two-wegmental die through resin injection molding or low melting point metal die casting. Thereby, productivity can be ameliorated remarkably.
