Abstract
The utility model discloses an automotive brushless generator having internal cooling and double-blade wheels. One blade wheel is arranged between a front end cover and a front claw pole, and the blade wheel is fixed onto the front claw pole, and however, the other blade wheel is arranged between a rear claw pole and a rear end cover, and the blade wheel is fixed onto the rear claw pole. The automotive brushless generator having internal cooling and double-blade wheels has the advantages of good ventilation and heat radiation, large output power, compact structure, strong interchangeability, stable performance, and long service life.
Description
The utility model relates to a kind of automotive brushless generator, and it is to be the supporting use of engine of power with automobile, tractor and with the internal combustion engine, is specially adapted to require to dispose the occasion of high-power output generator.
Along with automobile, the manufacturing fast development of tractor, require more and more higher to the generator performance supporting with it, especially the requirement to power output constantly increases, because output current increases, it is particularly outstanding that the heat dissipation problem of generator seems, have influence on the reliability of motor therefrom, we had once proposed a kind of automotive brushless generator of new structure in No. 88202607, Chinese patent CN, this generator has a little fan blade to be mounted between the rear end cap and the rotor claw utmost point, this structure can be improved the heat dissipation problem of high power output generator to a certain extent, but does not still satisfy actual needs.
Task of the present utility model is the automotive brushless generator that a kind of unique texture will be provided, it can make generator that bigger power output is arranged, and possessing again has good radiating condition, makes the performance of generator remain stable, life-saving has the advantage of compact conformation again.
Task of the present utility model is finished in such a way, the fore paw utmost point and the rear solid end utmost point of this generator amature are loaded onto fan blade respectively, these two fan blades can be that aluminium diecasting or tagger are towards part, if employing aluminium diecasting, available screw is fastened on pawl and extremely goes up, if towards part, then can welding at pawl, extremely goes up iron plate.The rotor main shaft of this internal cooling and double vanes turbo dynamo and internal stator can be similar to and propose generator among No. 88202607, the CN and settle like that.The brushless generator radiating effect of this structure is remarkable, and it makes the armature winding of generator and excitation winding temperature rise that tangible improvement arranged, and makes them that bigger electric current output can be arranged, and has improved the reliability of generator effectively.
Below in conjunction with accompanying drawing the utility model is further elaborated.
Fig. 1 is a complete machine cutaway view of the present utility model.
As seen from the figure, between the fore paw utmost point (1) of generator and front end housing (2), a fan blade (3) is arranged, this fan blade (3) is to be fixed on the fore paw utmost point (1), and a fan blade (6) is also arranged between the rear solid end utmost point (4) and rear end cap (5), and it then is to be fixed on the rear solid end utmost point (4).Fan blade (3) and (6) can be aluminium diecastings, at this moment will be screwed, and they also can be the iron plate stamping parts, at this moment then will they be fixed with electric soldering method.
The hydro-generator ventilation perfect heat-dissipating of this inner-cooled double-wind-impeller, power output is big, compact conformation, interchangeability is strong, can make generator keep steady-working state, long service life for a long time.
Claims (2)
1, a kind of automotive brushless generator of being formed by the fore paw utmost point (1), front end housing (2), the rear solid end utmost point (4), rear end cap (5), it is characterized in that: between the fore paw utmost point (1) and front end housing (2), a fan blade (3) is housed, it is fixed on the fore paw utmost point (1), between the rear solid end utmost point (4) and rear end cap (5) fan blade (6) is housed also, it is to be fixed on the rear solid end utmost point (4).
2, press the automotive brushless generator of claim 1 defined, it is characterized in that: when fan blade (3) and (6) are aluminium casting casting die, fan blade (3) and (6) will be screwed, and when fan blade (3) and (6) were the iron plate stamping parts, fan blade (3) and (6) wanted the electricity consumption solid welding to decide them.
