Abstract
The utility model relates to a novel pressure-cast aluminum alloy two-way fan blade which comprises a circular wheel flange, a wheel hub and a fan blade, wherein the circular wheel flange and the wheel hub are integrally cast, and the novel pressure-cast aluminum alloy two-way fan blade is characterized in that the fan blade is a combined fan blade and comprises a front curved part and a rear curved part, and the fan blade, the circular wheel flange and the wheel hub are pressure-cast into a whole. The utility model aims at providing the novel pressure-cast aluminum alloy two-way fan blade with great wind volume, high pressure and small load.
Description
Technical field
The utility model relates to a kind of motor air draft fan blade, is specifically related to the two-way fan blade of a kind of pack alloy.
Background technique
Along with various advanced technologies are applied on motor, motor is strengthened day by day, and power constantly promotes.The mechanical load and the heat dissipation problem of motor highlight day by day.Therefore the fan of motor is had higher requirement.
The existing used fan blade of motor mostly is the fan blade of weldering eliminant, Hand of spiral forward greatly, and cast aluminium, radial, direct palintrope, antecurvature formula fan blade are also arranged, and cast aluminium alloy is applied on the micro-machine more.Antecurvature formula class blade characteristics: blade is shorter and smaller, noise is low, pressure low (it is maximum to the gas acting to be blade), air quantity is big, efficient is low, the radius of curvature of fan blade is little; The backward bent vane characteristics: blade is long, at the bottom of the noise, pressure height, efficient height, air quantity radius of curvature little, blade be big.The Chinese invention patent application, application publication number: CN101922471A, name of patent application discloses a kind of fan blade for " a kind of fan blade of cooling fan of engine ", and it is integral with vane group by wheel hub and becomes fan by the shaft coupling structure with motor unit.The number of blade is five and is evenly distributed on the wheel hub.Blade is a torsional.This fan blade adopts antecurvature formula, and big air quantity can be provided, and noise is lower, but has also had the common drawback of antecurvature formula fan blade.
The two-way fan blade of a kind of novel pack alloy of the utility model adopts pack alloy, can give full play to the advantage of antecurvature formula fan blade and back curved fan blade, provides the novel pack alloy that a kind of air quantity is big, pressure is high, load is little two-way fan blade.
The model utility content
The utility model aims to provide the two-way fan blade of novel pack alloy that a kind of air quantity is big, pressure is high, load is little.
The technological scheme that the utility model adopted is: the two-way fan blade of a kind of novel pack alloy, comprise circular rim, wheel hub and air blade, circular rim, the integrated casting of wheel hub, it is characterized in that described air blade is the combined vanes sheet, turn of bilge and back turn of bilge before comprising, combined vanes sheet and circular rim, wheel hub are cast into one.
Described air blade and the wheel hub Duan Weiqian turn of bilge that joins accounts for 20% of air blade total length, and the air blade outside is the back turn of bilge, and back turn of bilge accounts for 80% of blade total length, links to each other for hypotenuse between back turn of bilge and the preceding turn of bilge.
The beneficial effects of the utility model are: adopt extrusion process, give full play to the advantage of antecurvature formula air blade and back curved air blade, overcome the deficiency, make air output increase about 40%, and do not influence the motor load of same size, reduce power consumption.Can be widely used on medium-and-large-sized motor and the blower.
Description of drawings
Accompanying drawing 1 is the perspective view of the two-way fan blade of a kind of novel pack alloy of the utility model;
Accompanying drawing 2 is the structural representations of facing of the two-way fan blade of a kind of novel pack alloy of the utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
Embodiment of the present utility model as shown in drawings, the two-way fan blade of a kind of novel pack alloy, comprise circular rim 1, wheel hub 2 and air blade 3, circular rim 1, wheel hub 2 integrated castings, turn of bilge 31 and back turn of bilge 32 before air blade 3 comprises, air blade 3 is cast into one with circular rim 1, wheel hub 2.Air blade 3 and the wheel hub 2 Duan Weiqian turn of bilge 31 that joins accounts for 20% of air blade 3 total lengths, and air blade 3 outside are back turn of bilge 32, and back turn of bilge 32 accounts for 80% of blade total length, links to each other for hypotenuse between back turn of bilge 32 and the preceding turn of bilge 31.The height of preceding turn of bilge 31 is lower, and the height of back turn of bilge 32 is about 4 times of preceding turn of bilge 31 height.
Claims (2)
1. two-way fan blade of novel pack alloy, comprise circular rim, wheel hub and air blade, circular rim, the integrated casting of wheel hub is characterized in that described air blade is the combined vanes sheet, turn of bilge and back turn of bilge before comprising, combined vanes sheet and circular rim, wheel hub are cast into one.
2. the two-way fan blade of a kind of novel pack alloy according to claim 1, it is characterized in that described air blade and the wheel hub Duan Weiqian turn of bilge that joins, account for 20% of air blade total length, the air blade outside is the back turn of bilge, back turn of bilge accounts for 80% of blade total length, links to each other for hypotenuse between back turn of bilge and the preceding turn of bilge.
