Abstract

1466863 Axial-flow fans PERKINS ENGINES Ltd 21 Feb 1974 [22 Feb 1973] 8795/73 Heading F1C In a fan, e.g. for cooling I.C. engines, the roots 12, Fig. 6, of the blades 11 are clamped between a pair of hub plates. The edges 17 of apertures 10 in the plates engage selected ones of serrations 16 in the roots to set the blades at the desired pitch. The roots may carry marks which can be aligned with arrows 21 on the plates to indicate the pitch setting. The plates are clamped together after assembly of the blades, by bending tabs 9 into locking engagement with one another, Fig. 5b (not shown). Frusto-conical portions 13 of the blades clamped between frusto-conical portions 7 of the plates, have a shallower taper than that of the portions 7 to restrain the blades against centrifugal effects. The blades may be moulded from plastics. In alternative embodiments the axes of the blades are tangential to a circle (25), Fig. 9 (not shown), centred on the fan axis, or lie on the surface of an imaginary cone having its axis coincident with the fan axis, Fig. 10 (not shown). In another embodiment, Fig. 11, the fan blades 29 extend radially inwardly with their roots clamped between a pair of hub rings 30, the assembly being supported by. rollers 31.
