Therefore, the bright body that includes of model utility, body is provided with gear chamber cover, be provided with a bent axle in the body, described bent axle is provided with crankshaft gear, drives a camshaft gear wheel by described crankshaft gear, mesh an exteranl gear by camshaft gear wheel again, thereby drive transmission shaft rotation; One electricity generating device is positioned on the gear chamber cover of body, and it includes a rotor and a stator, and its rotor is connected and fixed on described transmission shaft, makes the rotation of described bent axle and finally drives the friction rotor stator, realizes the purpose of generating.
Wherein, the number of teeth of described exteranl gear and crankshaft gear is the number of teeth 1/4 of camshaft gear wheel, makes to realize between camshaft gear wheel and crankshaft gear, the exteranl gear that transmission ratios is 4:1.
Wherein, the transmission shaft that rotor connected of described generator is to adopt the clutch shaft bearing and second bearing, and this is duplex bearing supported in gear chamber cover, and promptly described rotor is bearing in the gear chamber cover by the clutch shaft bearing and second bearing.
In addition, alternator assembly is installed in and is static closed pattern when working on the diesel engine, and promptly stator is exposed at the diesel engine front end outward and maintains static, and rotor then rotates in stator, and stator is provided with sealing cover, is to be used to prevent that silt, water from entering the generator inner chamber.
The engagement driving of the train of gearings in main generator amature of the beneficial effects of the utility model and the body, promptly drive camshaft gear wheel and exteranl gear by crankshaft gear, thereby drive the transmission shaft rotation, because rotor is fixedly connected on transmission shaft, therefore, when diesel engine is worked, directly drive generator work generating by the rotation of bent axle.
