Further, inner side reinforcement is provided with the madial wall of the wheel hub, the inner side reinforcement is in the wheel hub
The extension trend that extension trend on madial wall is connected to the root on the wheel hub with the blade is corresponding.
Further, multiple outside bosses are provided with the lateral wall of the wheel hub, the outside boss is fixed on
The connecting portion of the blade and the wheel hub.
Further, the outer side edges of the blade are provided with the anti-chimb that quivers, the anti-chimb that quivers close to blade trailing edge
Width increases gradually from blade inlet edge one end to blade trailing edge one end.
Further, extension is deviateed in the outside portion of the anti-chimb that quivers towards the lee face side of the blade.
Technical solution of the present invention has the beneficial effect that：It is specifically in the close of wheel hub by opening up Reduction of Students' Study Load groove on wheel hub
One end fluting of blade lee face, compared to traditional cylindrical hub, reduces knot unnecessary on a big chunk wheel hub
Structure, eliminates load unnecessary on wheel hub structure, makes overall more load of the lightweight to motor of axial-flow leaf smaller, the gas of fan blade
Dynamic performance is more excellent.
Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, makes required in being described below to embodiment
Accompanying drawing is briefly described, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for
For those of ordinary skill in the art, on the premise of not paying creative work, other can also be obtained according to these accompanying drawings
Accompanying drawing.
Fig. 1 is the structure chart of the lightweight low-load axial-flow leaf of the embodiment of the present invention.
Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Refer to shown in Fig. 1, the invention provides a kind of lightweight low-load axial-flow leaf, including wheel hub 1 and be arranged on wheel
It is provided with blade 2 on the lateral wall of hub 1, wheel hub 1 on axle sleeve 3, wheel hub 1 and is provided with Reduction of Students' Study Load groove 4 at least one, Reduction of Students' Study Load groove 4 is set
Put on one end of the lee face of the close blade 2 of wheel hub 1.
Specifically, it is specifically in one end of the lee face of close blade 2 of wheel hub 1 by opening up Reduction of Students' Study Load groove 4 on wheel hub 1
Fluting, compared to traditional cylindrical hub, reduces structure unnecessary on a big chunk wheel hub 1, eliminates the knot of wheel hub 1
Unnecessary load on structure, making axial-flow leaf, integrally more load of the lightweight to motor is smaller, and the aeroperformance of fan blade is more excellent.
Optimize as one of which, Reduction of Students' Study Load groove 4 includes curved section 4a, horizontal line section 4b and vertical line section 4c, and curved section 4a's walks
Trend to the root being connected to blade 2 on wheel hub 1 is corresponding.After so setting, the root setting that can be tried one's best along blade 2
Reduction of Students' Study Load groove 4, namely the unnecessary wheel hub structure of big excision that can try one's best.
As another optimization, reinforcing plate 5 is fixedly connected between wheel hub 1 and axle sleeve 3, the close blade 2 of reinforcing plate 5
Lightening grooves 6 are provided with one end of lee face.Preferably, lightening grooves 6 include the first oblique line section 6a, horizontal line section 6b and the second oblique line
The angle of section 6c, the first oblique line section 6a and the second oblique line section 6c and horizontal plane is 70~85 degree.
Improved as one of which, inner side reinforcement 7 is provided with the madial wall of wheel hub 1, inner side reinforcement 7 is in wheel hub 1
The extension trend that extension trend on madial wall is connected to the root on wheel hub 1 with blade 2 is corresponding.
Specifically, blade 2 be connected to the root position on wheel hub 1 structural strength it is particularly significant, in the madial wall of wheel hub 1
Reinforcement 7 on the inside of upper setting, and the reinforcement is that the root of correspondence blade 2 is set so that root of blade, wheelboss side wall and interior
Side reinforcement constitutes an entirety, and structural strength and stability are more excellent.
Improved as another, be provided with multiple outside bosses 8 on the lateral wall of wheel hub 1, outside boss 8 is fixed on
The connecting portion of blade 2 and wheel hub 1.Outside boss 8 is similarly disposed at the root of blade 2, is beneficial to the structural strength of blade 2
Lifting.
As one of which embodiment, the outer side edges of blade 2 are provided with the anti-chimb 9 that quivers at the trailing edge of blade 2, anti-to quiver
The width of chimb 9 increases gradually from the leading edge one end of blade 2 to the trailing edge one end of blade 2.
Specifically, the blade 2 of axial-flow leaf can not stop vibration in high-speed rotation because high velocity air and vortex etc. influence
Noise is formed, air-flow enters from the leading edge one end of blade 2 axially to be blown out through the windward side of blade 2 by the trailing edge one end high-speed mobile of blade 2,
The anti-chimb 9 that quivers gradually broadened has certain inhibitory action to the disorderly air-flow of unordered disturbance, can reduce the shape of partial noise
Into.
Preferably, extension is deviateed in the outside portion of the anti-chimb 9 that quivers towards the lee face side of blade.Specifically, the chimb 9 that quivers is prevented
Outer ledge extends towards the lee face of blade 2, has drainage to the disorderly air-flow at windward side edge, is ensureing air output change
In the case of less, partial noise can be reduced to a certain extent.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications
It should be regarded as protection scope of the present invention.
