Abstract
The utility model discloses an electric generator which comprises a generator housing, a stator assembly, a rotor assembly, a carbon brush assembly, an adjustor and a rectifier, wherein the stator assembly, the rotor assembly, the carbon brush assembly, the adjustor and the rectifier are arranged in the generator housing. The generator housing is composed of a housing body and a protecting cover. The adjustor and the rectifier are respectively arranged in the protecting cover. A front fan and a rear fan are arranged on a rotor shaft of the rotor assembly arranged in the generator housing. Ventilation openings are formed in the front end and the rear end of the generator housing respectively. The protecting cover is threaded to the housing body and provided with heat dissipating holes. The front fan and the rear fan are welded on the rotor shaft. According to the electric generator, the split structure is adopted by the generator housing so that maintenance is convenient, and the cooling efficiency is further improved.
Description
Technical field
The utility model relates to a kind of generator.
Background technology
Generator is other forms of energy conversion to be become to the plant equipment of electric energy; It is driven by the hydraulic turbine, steam turbine, diesel engine or other dynamic power machines, and the Conversion of Energy that current, air-flow, fuel combustion or nuclear fission are produced is that mechanical energy is passed to generator, then is converted to electric energy by generator.Generator has been widely used in industrial and agricultural production, national defence, science and technology and daily life.As shown in Figure 1, be the structural representation of comparatively conventional in the market generator, its casing 1 adopts integral structure, and rectifier 12, adjuster 13 are built in to casing 11, not only safeguard inconvenience, and cooling effect is poor, in addition, the fan 14 of this kind of motor is placed in casing 11 outsides, and cooling effectiveness is lower, thereby in the situation that guaranteeing certain specification power, need select thicker wire diameter, thus, copper loss amount is larger, and causes the volume of generator larger.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of generator is provided, and safeguard inconvenient problem, and conventional electric generators cooling effect is poor to solve conventional electric generators, needs to adopt the copper loss amount causing compared with thick wire diameter larger, the problem that generator volume is large.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of generator, comprise casing and be arranged at stator module, rotor assembly, carbon brush component, adjuster, the rectifier in casing, described casing adopts split-type structural, by housing, protective cover, formed, described adjuster, rectifier are all arranged in protective cover, on the armature spindle of casing internal rotor assembly, be provided with forefan, aft-fan, and the front end of casing, rear end all have ventilating opening.
Further, described protective cover is threaded with housing.
Further, on described protective cover, have louvre.
Further, described forefan, aft-fan are all welded on armature spindle.
The beneficial effects of the utility model are, described a kind of generator is by being built in fan in casing, effectively improved cooling effectiveness, and casing employing split-type structural, be convenient to safeguard, and rectifier, adjuster are placed in the protective cover that has louvre, further improve cooling effect, thereby realized in the situation that guaranteeing certain specification power, selected thinner wire diameter, reduce copper loss amount, reduced volume, the weight of generator.

Fig. 2 is the structural representation of a kind of generator of the utility model.
In figure:
11, casing; 12, rectifier; 13, adjuster; 14, fan; 21, housing; 22, ventilating opening; 23, forefan; 24, armature spindle; 25, rectifier; 26, protective cover; 27, adjuster; 28, aft-fan.
Embodiment
Below in conjunction with accompanying drawing and by embodiment, further illustrate the technical solution of the utility model.
Please refer to shown in Fig. 2, Fig. 2 is the structural representation of a kind of generator of the utility model; In the present embodiment, a kind of generator, comprise casing and be arranged at stator module, rotor assembly, carbon brush component, adjuster 27, the rectifier 25 in casing, described casing consists of housing 21, protective cover 26, on described protective cover 26, have louvre, and it is threaded with housing 21, described adjuster 27, rectifier 25 are all arranged in protective cover 26, on the armature spindle 24 of casing internal rotor assembly, be welded with forefan 23, aft-fan 28, and the front end of casing, rear end all have ventilating opening 22.
The utlity model has good cooling results, volume is little, lightweight, copper loss amount is little feature.
Above embodiment has just set forth basic principle of the present utility model and characteristic; the utility model is not limited by above-described embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
