Abstract
The utility model provides a fan blade of an asynchronous motor and belongs to the technical field of motors. The fan blade of the asynchronous motor solves the problems of unreasonable structure and material wasting of a fan blade of an asynchronous motor in the prior art. The fan blade of the asynchronous motor comprises a fan blade body, and a shaft hole is arranged in the middle of the fan blade body. The fan blade body includes a fan body and a plurality of blades, the plurality of blades are arranged outside the fan body and perpendicular to the fan body, and a plurality of openings corresponding to the shapes of the blades are arranged outside the fan body. The fan blade of the asynchronous motor has the advantages of being reasonable in structure and material-saving.
Description
Technical field
The utility model belongs to technical field of motors, has related to a kind of asynchronous motor, has especially related to a kind of flabellum of asynchronous motor.
Background technique
Asynchronous motor comprises motor field frame and is contained in the fan housing of shell end, because motor is in operation process, the rotation heating of rotor and the heating of coil can make that motor field frame is inner to produce a large amount of heats, therefore need utilize flabellum to dispel the heat.
There are 2 deficiencies in flabellum in the market, and first blade structure is reasonable inadequately, causes the radiating effect deficiency of flabellum; It two is that waste of material is more in the manufacture process of flabellum, causes the manufacture cost of flabellum to increase, to such an extent as to reduce the product competitive ability of enterprise.
Summary of the invention
There are the problems referred to above in the utility model at existing technology, has proposed a kind of flabellum of rational in infrastructure, the asynchronous motor of saving material.
The utility model is realized by following technical proposal: a kind of flabellum of asynchronous motor, comprise the flabellum body, described body middle part has axis hole, it is characterized in that, described body comprises fan body portion and is positioned at the outside a plurality of blades perpendicular with it of fan body portion, and the outside of described fan body portion has a plurality of openings corresponding with the shape of blade.
In this flabellum, the perpendicular effective wind face that can improve blade of blade and fan body portion, the air quantity of raising flabellum, the while has also been improved the intensity of fan; The shape of opening is corresponding with the shape of blade, can effectively will be used as blade from the material that opening takes out in course of working, has saved material.
In the flabellum of above-mentioned a kind of asynchronous motor, described blade has a base, and the length on described base is 1/4～1/2 of body radius.
In the flabellum of above-mentioned a kind of asynchronous motor, described blade has an arc-shaped side edges, the arc length of described arc-shaped side edges be between adjacent two blades arc length 1/4～1/2.
In the flabellum of above-mentioned a kind of asynchronous motor, the quantity of described blade is 8～12.
In the flabellum of above-mentioned a kind of asynchronous motor, described body adopts plastics to make.
Compared with prior art, the fan of this asynchronous motor has the following advantages:
1, blade and fan body portion are perpendicular, have improved effective wind face of blade, thereby increase the air quantity of flabellum, have improved radiating effect; Optimization by to the length of the base of blade and side makes that the structure of flabellum is more reasonable, has strengthened intensity and the working life of flabellum.
2, the sectional shape of blade is corresponding with opening, and in process of production, the material of blade can be taken from opening, has the advantage of saving material, reducing cost.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1, body; 2, fan body portion; 3, blade; 3a, base; 3b, arc-shaped side edges; 4, opening; 5, axis hole.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiments.
The flabellum of a kind of asynchronous motor as shown in Figure 1, comprise flabellum body 1, described body 1 middle part has axis hole 5, described body 1 comprises fan body portion 2 and is positioned at the outside a plurality of blades 3 perpendicular with it of fan body portion 2, and the outside of described fan body portion 2 has a plurality of openings corresponding with the shape of blade 34.In this flabellum, body 1 adopts plastics to make, blade 3 and fan body portion 2 perpendicular effective wind faces that can improve blade 3, and the air quantity of raising flabellum, the while has also been improved the intensity of fan; The shape of opening 4 is corresponding with the shape of blade 3, can effectively the material that takes out from opening 4 be used as blade 3 in course of working, has saved material.
Simultaneously, the shape of blade 3 has also been carried out rational improvement.Blade 3 has a base 3a, and the length of this base 3a is 1/4～1/2 of body 1 radius, and in this number range, the structure of blade 3 is comparatively reasonable, and the air quantity of flabellum is bigger.In the present embodiment, the length of base 3a is 2/5 of body 1 radius.Blade 3 has an arc-shaped side edges 3b, the arc length of described arc-shaped side edges 3b be between adjacent two blades 3 arc length 1/4～1/2.In this number range, the structure of blade 3 is comparatively reasonable, and the air quantity of flabellum is bigger.In the present embodiment, the arc length of arc-shaped side edges 3b be between adjacent two blades 3 arc length 1/3.The quantity of blade 3 is 8～12.In the present embodiment, the quantity of blade 3 is 10.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used terms such as body 1, fan body portion 2, blade 3, base 3a, arc-shaped side edges 3b, opening 4, axis hole 5 morely, do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
