Abstract
A novel fan blade belongs to the technical field of fan manufacturing, The fan blade is characterized in that one or more strengthening ribs are longitudinally arranged in a blade cavity between an upper blade web plate and a lower blade web plate; the strengthening ribs are in branch connection with the upper blade web plate and the lower blade web plate; a circular chamfer angle is formed on the outer side of the joint of the strengthening rib and the upper blade web plate and the lower blade web plate; and a triangular notch is formed on the inner side thereof. In the utility model, through the additional arrangement of the strengthening ribs, the mechanical structure of the fan blade is improved; and under the condition that hardening material is not changed, the thickness of a blade housing is reduced by 30 percent to 40 percent, the weight of the blade housing is reduced by about 30 percent, and the manufacturing and using costs are saved. The novel fan blade has the advantages of high strength, higher stiff force and shock resistance, high power, long service life, energy conservation and consumption reduction, and the like.
Description
Technical field
The utility model relates to fan manufacturing technology field.
Background technique
At present, existing fan blade mostly is hollow-core construction, because mechanical structure does not meet the particular requirement of blade, its intensity, very power and impact resistance are relatively poor, cause in the fan blade using process easily torsional deformation, extrusion damage, reduced the wind energy efficiency of blade, influenced working life, the method that blade strength improves in manufacturer is to change reinforcing material or bulged blading shell, but has increased production and user cost simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of novel fan blade, with solve prior art intensity, very power and impact resistance are relatively poor, cause in the fan blade using process easily torsional deformation, extrusion damage, the wind energy efficiency of blade is low, and working life is short, problems such as cost of production height.
To be that blade cavity is indoor between upper and lower two blade webs vertically be provided with one or multi-channel stiffening rib to the technological scheme that its technical problem that solves the utility model adopts, stiffening rib is connected with upper and lower blade web bifurcated, the outside, joint forms circular chamfering, the inboard delthyrium that forms.
Adopting good effect of the present utility model is by stiffening rib being set, having improved the mechanical structure of blade, can be under the situation of not changing reinforcing material, make the thickness of blade enclosure reduce 30-40%, about weight saving 30%, greatly reduce and make and user cost, have the intensity height, very power and impact resistance are stronger, anti-twist distortion, anti-extrusion damage, the wind energy of blade is effective, long service life, energy-saving and cost-reducing, advantage such as produce and operating cost is low.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples:
Accompanying drawing 1 is the utility model structural representation:
Accompanying drawing 2 is the utility model blade profile structural representation:
1 blade web, 2 blade chambers, 3 stiffening ribs, 4 blade handles, 5 chucks, 6 circular chamferings, 7 delthyriums among the figure.
Embodiment
As shown in Figure 1, 2: twice stiffening rib 3 vertically is arranged in the blade chamber 2 between blade two webs 1, and stiffening rib 3 is connected with last bottom web bifurcated, and the outside, joint forms circular chamfering 6, the inboard delthyrium 7 that forms.Blade web 1, blade handle 4, chuck 5 structures are same as the prior art.
Adopt structural design of the present utility model, also can make the fan blade series product of one or multi-channel stiffening rib as required.
Claims (3)
1. a novel fan blade mainly is made up of last bottom web, blade handle, chuck; It is characterized in that between upper and lower two blade webs that blade cavity is indoor vertically is provided with one or multi-channel stiffening rib.
2. according to the described novel fan blade of claim 1, it is characterized in that stiffening rib is connected with upper and lower blade web bifurcated.
3. according to claim 1,2 described novel fan blades, it is characterized in that stiffening rib and the upper and lower blade web joint outside forms circular chamfering, the inboard delthyrium that forms.
