On the other hand, existing generator, be provided with in motor and utilize electromagnetic induction principle to carry out generating electricity or the stators and rotators of Driving Torque, rotor is made up of magnetic shoe usually, in petrol engine, the magneto that promising gasoline engine starting provides power is also set usually, wherein, stator is usually arranged at magnetic shoe in wind scooper and is fixed on wind scooper inwall and the magnetic shoe that together can rotate with wind scooper, and magnetic shoe needs to utilize an annular mounting bracket to be fixed is arranged on wind scooper inwall, this annular mounting bracket generally adopts molding and forming, and enter glue at the home position of support, and adopt the runner of spoke shpae that liquid plastic cement is injected the die cavity of annular, band injection moulding complete and cooling after, manufacturing operator needs the clout of spoke shpae to cut, cause the annular mounting frame of existing magnetic shoe in manufacturing, larger to the waste of plastic material, prune the labor intensity that clout too increases workman simultaneously, increase manufacture cost.
Therefore, for overcoming the above problems, need a kind of cooling fan, this cooling fan can be installed on wind scooper inside, and to reduce air intake resistance, fan uses by as magnetic shoe mounting bracket simultaneously, fan and magnetic shoe mounting bracket is made to share component, to reduce the cost of production of magnetic shoe mounting bracket, significantly reduce the size of the equipment such as generator, motor or petrol engine simultaneously, make its structure compacter.
Model utility content
In view of this, the purpose of this utility model overcomes defect of the prior art, there is provided one can be used as cooling fan and as magnetic shoe mounting bracket, the cooling fan that the device structures such as the generator of this fan of employing, motor or petrol engine are compacter can be made again.
Cooling fan of the present utility model, comprise inner ring, outer ring and be connected to the spoke shpae flabellum between inner ring and outer ring, cycle surface is provided with the erection column for fixedly mounting magnetic shoe;
Further, described fan is centrifugal fan;
Further, described flabellum towards air-out to side be provided with for guiding air-flow along the guide plate of fan Radial Flow, guide plate the inner is connected to fan inner ring periphery, and guide plate outer end is along flabellum longitudinal extension and guide plate outer end is provided with exhaust outlet;
Further, described fan is made by molding and forming;
Further, described erection column is identical with flabellum quantity and arrange with flabellum one_to_one corresponding;
Further, described flabellum towards air intake to side be provided with escape groove;
Further, described flabellum is provided with multiple and is uniformly distributed along inner ring circumference;
Further, described erection column root passes through round-corner transition.
The beneficial effects of the utility model are: cooling fan of the present utility model, can be used for generator, motor, petrol engine etc. utilizes electromagnetic induction principle to carry out generating electricity or the equipment of Driving Torque, this cooling fan can as the air source apparatus of air cooling system, again can as the mounting bracket of magnetic shoe in electromagnetic induction element, make parts reach multiple use, effectively reduce cost of production.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the right elevation of Fig. 1;
Fig. 4 is the structural representation of the utility model for petrol engine air cooling system.
Embodiment
Fig. 1 is structural representation of the present utility model.Fig. 2 is the left view of Fig. 1; Fig. 3 is the right elevation of Fig. 1; Fig. 4 is the structural representation of the utility model for petrol engine air cooling system.As shown in the figure, cooling fan 2 in the present embodiment, the spoke shpae flabellum 7 comprising inner ring 10, outer ring 6 and be connected between inner ring 10 and outer ring 6, outer ring 6 end face is provided with the erection column 1 for fixedly mounting magnetic shoe 4, and as shown in Figure 4, in figure, arrow is the direction of air current flow, in the present embodiment, cooling fan 2 is installed in the air cooling system with existing general gasoline engines, and this air cooling system comprises wind scooper 3, is located at the stator 5 in wind scooper 3 and magnetic shoe 4; Magnetic shoe 4 is embedded on erection column 1 and also together can rotates with fan 2, cooling fan 2 in the present embodiment is both as the air source apparatus of air cooling system, again as the mounting bracket of magnetic shoe in electromagnetic induction element 4, make parts reach multiple use, effectively reduce cost of production.
In the present embodiment, described fan 2 is centrifugal fan 2, the air-flow that centrifugal fan 2 produces flows radially outward along fan 2, when air-flow runs into wind scooper 3 madial wall, axially move to stator 5 effluent along fan 2 after airflow direction changes, the comparatively Wind Volume that centrifugal fan 2 can produce and blast, ensure cooling effect.The flabellum 7 of the centrifugal fan 2 that the present embodiment adopts is for being parallel to the plate flabellum 7 of fan 2 axis, and this structure is easy to the demoulding after shaping, and manufacturability is better.
In the present embodiment, described flabellum 7 towards air-out to side be provided with for guiding air-flow along the guide plate 8 of fan 2 Radial Flow, guide plate 8 the inner is connected to fan 2 inner ring 10 periphery, guide plate 8 outer end is along flabellum 7 longitudinal extension and guide plate 8 outer end is provided with exhaust outlet 11, guide plate 8 can effectively guide gas along fan 2 Radial Flow, thus increase wind speed and the blast of fan 2 generation, strengthen cooling effect.
In the present embodiment, described fan 2 is made by molding and forming, and the fan 2 be made of plastics is lightweight, rotary inertia is little, and cost of production is lower simultaneously, because flabellum 7 can be used as shaping required runner, therefore, without the need to pruning clout after shaping, also improve the utilization ratio of plastic material simultaneously.
In the present embodiment, described erection column 1 is identical with flabellum 7 quantity and arrange with flabellum 7 one_to_one corresponding, and the magnetic shoe 4 in electromagnetic induction element can be embedded between two adjacent locating columns.
In the present embodiment; described flabellum 7 towards air intake to side be provided with escape groove 9; after fan 2 installation; its towards air intake to side generally can arrange near wind scooper 3; and wind scooper 3 can be provided with usually the fastening pieces such as bolt; therefore, arranging escape groove 9 in flabellum 7 side can avoid flabellum 7 to interfere with the fastening piece on wind scooper 3 or wind scooper 3.
In the present embodiment, described flabellum 7 is provided with multiple and is uniformly distributed along inner ring 10 circumference, and equally distributed flabellum 7 can produce lasting and stable air-flow, ensures the effect of cooling.
In the present embodiment, described erection column 1 root is by round-corner transition, and because fan 2 is in rotation process, locating column need drive magnetic shoe 4 together to rotate, therefore the flexural stress of its root is comparatively large, because adopting round-corner transition, avoids stress to concentrate.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
