The rotating shaft is arranged on the stator. The two ends of the rotating shaft are axially extending out of the two ends of the stator. The rotor core is arranged on the rotating shaft and the rotor coil is arranged on the rotor core. One extended end of the rotating shaft, which is positioned at the outer side of the end portion of the stator, is provided with a rotary rectifying disc. According to the technical scheme of the utility model, the technical problems of inconvenient assembly and disassembly, inconvenient maintenance and poor heat radiation effect are solved.
Description
Technical field
The utility model relates to generator.
Background technology
At present, the principle of some generator is by outer power rotor driven rotation, simultaneously, to the AC exciter energising, make the rectifying disc generation current and supply in the rotor coil generation rotating magnetic field after the rotor coil energising, make the coil generation current on the stator, realize the purpose of generating.In the past, AC exciter and rectifying disc all are installed in the stator, and its defective is then to need rectifying disc is installed in the rotating shaft in the assembling rotor, and rear assembling stator has brought constant to installation; In addition, the dismounting rectifying disc is also inconvenient, has brought trouble to maintenance; Have, when AC exciter and rectifying disc were installed in the stator, the position of AC exciter, rectifying disc, rotor and stator was more concentrated again, and the heat of generation is also concentrated, and has brought inconvenience to heat radiation, can affect the useful life of generator.
Summary of the invention
The purpose of this invention is to provide a kind of generator with external rectifying disc, technical problem to be solved is to install, dismantle inconvenience, and maintenance is also inconvenient, and radiating effect is bad.
The technical scheme that solves the problems of the technologies described above is: a kind of generator with external rectifying disc comprises stator and rotor; Rotor comprises rotating shaft, rotor core and rotor coil, and rotating shaft is installed on the stator, and the two end axles of rotating shaft to stretch out the stator both ends, rotor core is installed in the rotating shaft, rotor coil is located on the rotor core; Outside a wherein external part of rotating shaft is positioned at stator end, rotating rectifier dish is installed.
Said structure, owing to rotating rectifier dish has been installed to the external part of rotating shaft, and rotating rectifier dish being positioned at outside the stator end, like this, after stator and rotor all assembled rotating rectifier dish being installed again gets final product, when dismounting, do not need to dismantle rotor and stator yet, directly dismantle rotating rectifier dish from the outside and get final product, therefore, make things convenient for the installation and removal of rotating rectifier dish, also be convenient to keep in repair rotating rectifier dish, thereby reduced maintenance cost; In addition, rotating rectifier dish and rotor, stator disperse to install, the spread heat of generation, and good heat radiation, rapid heat dissipation, therefore, heat radiation effective.
As improvement, be covered with the outer cover that is connected with stator at rotating rectifier dish; With the protection rotating rectifier dish, and can improve the security performance of using.
As improvement, outer cover is provided with louvre, to improve radiating effect.
As improvement, in rotating shaft, have the central duct of extending to the other end from rotating rectifier dish one end is installed, have the radially duct of radially extending and communicating with central duct in rotating shaft; Connecting line passes radially, and duct and central duct are electrically connected rotor coil and rotating rectifier dish.Because of the demand of installing, need between rotor coil and rotating rectifier dish, bearing be installed in the rotating shaft, like this, brought trouble for the electric connection of rotor coil and rotating rectifier dish, by central duct and duct radially are set, connecting line then can pass central duct and radially the duct with rotor coil and rotating rectifier dish electric connection, like this, when rotor, connecting line and rotating rectifier dish are followed rotor and are together rotated, and have well solved above-mentioned technical problem.
