Section bracing piece and afterbody bracing piece, one end of the stage casing bracing piece are fixed on the lee face and the hub contacts of the blade
The middle part at position, the other end of the stage casing bracing piece is fixed on the annular support member, one end of the afterbody bracing piece
One end of the lee face of the blade and the close blade trailing edge at the hub contacts position is fixed on, the afterbody bracing piece
The other end is fixed on the annular support member.
Further, be provided with the madial wall of the wheel hub is used to strengthen the blade correspondingly with the blade
The medial reinforcement of structural stability, trend of the medial reinforcement on the wheel hub madial wall is fixed on the blade
Root on the wheel hub lateral wall moves towards identical.
Further, multiple reinforcement salient points are provided with the lee face of one end of the close wheel hub of the blade.
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：By setting annular support member in wheel hub one end, and in annular brace
Twice bracing piece is set between part and blade lee face, is specifically stage casing and the tail of the root position being connected in blade with wheel hub
End, sets bracing piece respectively, support firm effect well is served to blade, its structural strength and operation stability are more excellent
It is different.
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 a kind of structure chart of the enhanced axial-flow leaf of structure 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 enhanced axial-flow leaf of structure, including wheel hub 1 and be arranged on
Blade 2 on the lateral wall of wheel hub 1, one end of the lee face of the close blade 2 of wheel hub 1 is provided with annular support member 3, annular brace
Part 3 keeps coaxial with wheel hub 1, is provided with the outer peripheral sidewall of wheel hub 1 and the one-to-one stage casing bracing piece 4 of blade 2 and afterbody
Bracing piece 5, one end of stage casing bracing piece 4 is fixed on the lee face of blade 2 and the middle part of the contact site of wheel hub 1, stage casing bracing piece 4
The other end be fixed on annular support member 3, one end of afterbody bracing piece 5 is fixed on the lee face and the contact site of wheel hub 1 of blade 2
One end of the trailing edge of close blade 2 of position, the other end of afterbody bracing piece 5 is fixed on annular support member 3.
Specifically, by setting annular support member 3 in the one end of wheel hub 1, and annular support member 3 and the lee face of blade 2 it
Between twice bracing piece is set, be specifically the stage casing of root position and tail end be connected in blade 2 with wheel hub 1, respectively setting reinforcement
Bar, support firm effect well is served to blade, its structural strength and operation stability are more excellent.
Improved as one of which, be provided with the madial wall of wheel hub 1 is used to strengthen blade 2 correspondingly with blade 2
The medial reinforcement 6 of structural stability, trend of the medial reinforcement 6 on the madial wall of wheel hub 1 is fixed on outside wheel hub 1 with blade 2
Root on the wall of side moves towards identical.
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
Upper setting medial reinforcement 6, and the reinforcer is that the root of correspondence blade 2 is set so that root of blade, wheelboss side wall and interior
Side reinforcer constitutes an entirety, and structural strength and stability are more excellent.
Improved as another, multiple reinforcement salient points 7 are provided with the lee face of one end of the close wheel hub 1 of blade 2.
Specifically, strengthen salient point 7 to be arranged on the lee face of blade 2, and be connected to close to blade 2 at the root of wheel hub 1
Set, the structural strength of blade 2 is strengthened in the enhanced form of multiple spot.
As one of which embodiment, the outer side edges of blade 2 are provided with the anti-chimb 8 that quivers at the trailing edge of blade 2, anti-to quiver
The width of chimb 8 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 8 that quivers gradually broadened has certain inhibitory action to the disorderly air-flow of unordered disturbance, can reduce the shape of partial noise
Into.
As another embodiment, extension is deviateed in the outside portion of the anti-chimb 8 that quivers towards the lee face side of blade 2.
Specifically, the outer ledge of the anti-chimb 8 that quivers extends towards the lee face of blade 2, to the disorderly air-flow at windward side edge
There is drainage, in the case where ensureing air output change 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
