Description
Technical field
The utility model is related to centrifugal blower technical field, specifically a kind of centrifugation wind with wheel cap reinforcement structure
Machine impeller.
Background technology
Existing centrifugal blower fan blade wheel is made of wheel cap, wheel disc and blade, and wherein wheel cap generally has flat wheel cap, taper
Wheel cap and arc wheel cap etc. are several, and taper wheel cap and the flat wheel cap of arc wheel cap pneumatic efficiency ratio are superior, so efficient centrifugal wind turbine
It is generally used taper wheel cap and arc wheel cap；Blade shape has one-board blade (including plate shaped and arc-shaped), Yi Jiji
The advantages of air-foil blade, this structure is：When air-flow vertical impact blade, can have the function that reduce gas-flow resistance.Its
Deficiency is：One-board blade construction is relatively thin, and wheel speed is relatively low, limits the aeroperformance of wind turbine to a certain degree,
When being rotated under working speed, wheel cap generates stress concentration and deformation under the action of the centrifugal force with blade contact position；Airfoil leaf
Chip architecture intensity is higher, can bear higher rotation speed, but the processing and fabricating of blade is more complicated.Based on above two blade profile
Disadvantage, while ensureing that art of vane is simple, and excellent aeroperformance can be achieved in blade wheel structure intensity height.
Utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, is provided a kind of strong with structure novel, structure
It spends, the centrifugal blower fan blade wheel with wheel cap reinforcement structure that resistance is small, aeroperformance is excellent.
Technical solution adopted by the utility model to solve its technical problems is：
A kind of centrifugal blower fan blade wheel with wheel cap reinforcement structure, including wheel disc, wheel cap, wheel hub and blade, the wheel disc
It is that full weld is connect with wheel cap, the blade and wheel hub integrally connected, blade is along wheel rotation direction circumference uniform distribution；Outside the wheel cap
Side is equipped with the reinforcing rib of circular ring shape；Wheel cap maximum stress and maximum distortion when the reinforcing rib is located at the work of impeller rated speed
Position, outer diameter is consistent at wheel cap maximum stress when internal diameter works with impeller rated speed.
Preferably, the reinforcing rib to the junction of wheel cap and wheel disc is inner arc structure；The reinforcing rib is to wheel cap
End is pyramidal structure.
Preferably, the reinforcing rib is metal bar or plank.
Preferably, the blade is single plate blade and is backward type structure.
Structure novel, structural strength is good, resistance is small, aeroperformance is excellent due to using the above structure, having for the utility model
The advantages that good.
Description of the drawings
A part of attached drawing for constituting the utility model is used to provide a further understanding of the present invention.In the accompanying drawings：
Fig. 1 is the side structure schematic diagram for the centrifugal blower fan blade wheel that the utility model has wheel cap reinforcement structure.
Fig. 2 is the planar structure schematic diagram for the centrifugal blower fan blade wheel that the utility model has wheel cap reinforcement structure.
In figure：1, wheel disc；2, wheel cap；3, wheel hub；4, blade；5, reinforcing rib.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, 2, a kind of centrifugal blower fan blade wheel with wheel cap reinforcement structure, including wheel disc 1, wheel cap 2, wheel hub 3
With blade 4, the wheel disc 1 is that full weld is connect with wheel cap 2, and the blade 4 and 3 integrally connected of wheel hub, blade 4 is along wheel rotation side
To circumference uniform distribution；2 outside of the wheel cap is equipped with the reinforcing rib 5 of circular ring shape；When the reinforcing rib 5 is located at the work of impeller rated speed
The position of 2 maximum stress of wheel cap and maximum distortion, internal diameter and outer diameter at 2 maximum stress of wheel cap when the work of impeller rated speed
Unanimously.The reinforcing rib 5 is metal bar or plank.The blade 4 is single plate blade and is backward type structure.
The reinforcing rib 5 to the junction of wheel cap 2 and wheel disc 1 is inner arc structure；The reinforcing rib 5 is to the end of wheel cap 2
End is pyramidal structure.
The reinforcing rib 5 is not when reinforcing the work of impeller rated speed, according to estimation with 2 maximum stress of wheel cap and deforming position
The size set determines blank size, and bent reshaping is carried out after blanking is circular ring shape, internal radius and 2 maximum stress of wheel cap
It is consistent to locate outer diameter, can ensure that 5 inside of reinforcing rib is bonded completely with wheel cap 2 when to fix wheel cap 2 and play the role of structural strengthening.
Not reinforced conventional blade wheel structure passes through strength estimation, maximum distortion and location of maximum stress generally blade with
And 2 position of wheel cap, after being reinforced by wheel cap 2, impeller deforms be obviously reduced under the influence of centrifugal force, while corresponding centrifugal stress
Also it reduces, the safety coefficient of structural strength when improving impeller operation.In addition to airflow function when impeller rotates, air-flow is along leaf
Wheel import flows to the steering variation that air-flow occurs for outlet port, which is the working region of air-flow, and 2 outside of wheel cap is not gas
The working region of stream, therefore reinforced by 2 outside of wheel cap, while improving structural strength, the resistance of air-flow will not be caused to increase
Add, impeller is enable to ensure the higher pneumatic efficiency of former pneumatic structure.The inner arc and taper structure design of wheel cap 2, at the same it is simultaneous
The advantages of for arc wheel cap and taper wheel cap, further improve the pneumatic efficiency of impeller.
Although the utility model is described in detail with reference to the foregoing embodiments, those skilled in the art is come
Say, still can with technical scheme described in the above embodiments is modified, or to which part technical characteristic into
Row equivalent replacement, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should all
It is included within the scope of protection of this utility model.
