Abstract

1435864 Axial-flow fans ALUMETALL GmbH 12 June 1974 [13 June 1973] 26166/74 Heading F1C A fan impeller comprises a carrier ring 4 with integral blades 5 and formed from plastics material and connected to a metal hub in the form of an annular disc 3 formed with bores 6 which extend parallel to one another and through which passes the plastics material of a substantially radial web 8 formed integrally with the ring 4. The bores 6 are arranged in two pitch circles of different diameter, the bores in one circle being staggered in relation to those in the other. Further bores 7 serve for securing the impeller to a driving shaft. A shorter ring 10 is connected to the main ring 4 by radial ribs 11 and to the web 8 by radial ribs 12. The part of the disc 3 not covered by plastics material may be dished.
