The aerogenerator is mainly applied to the field of wind power generation and has the advantages of low cost, and simple and reliable structure.
Description
Technical field
The utility model relates to wind-driven generator, is specifically related to a kind of pin configuration of wind power generator rotor.
Background technology
Generator is to be the device that media converts mechanical energy into electric energy with magnetic field.Magnetic field is the basis of realizing mechanical energy is converted to electric energy, and produce magnetic field has dual mode, and a kind of is that helical coil is generated an electromagnetic field under the state of energising; Another kind is to utilize permanent magnet to produce magnetic field.Present most of permanent magnet direct drive synthronous wind-mill generator uses permanent magnet to produce magnetic field more, the cutting magnetic line generating.
Present known generator amature pin configuration is in rotating shaft, to slot; With the soft copper connecting line imbed the fluting in be connected with collector ring; This kind connected mode is commonly referred to as and is flexible coupling; Be flexible coupling the processing request of countershaft than higher, and exist and install and dismounting is inconvenient, shortcomings such as security performance is not high, reliability is low, Yi Qichao.
The utility model content
To above-mentioned prior art, the utility model provides a kind of pin configuration of novel wind generator rotor, the difficulty of processing that solves the countershaft that is flexible coupling than higher, install and dismounting is inconvenient, reliability is low, the shortcoming of Yi Qichao.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of pin configuration of wind power generator rotor; Comprise rotating shaft (1); Collector ring (4); Said rotating shaft (1) is provided with cavity, and cavity is equipped with the insulator sleeve (3) that is sintered into by hard copper wire and insulating material, and insulator sleeve (3) is provided with and is used for it is drawn the insulator joint pin (2) that is connected with collector ring with the rotor winding coil; The rubber positioning sleeve (5) that is used for fixing insulator sleeve (3) also is housed in the cavity, and said cavity opening part is provided with the self-locking nut (6) that is used for bore seal.
The pin configuration of described a kind of wind power generator rotor, said cavity is about rotating shaft central axis symmetry.
The utility model compared with prior art has following beneficial effect: it is to sinter copper cash and insulating material into the insulation joint pin; Be connected with rotor coil and collector ring respectively with the insulation joint pin again; Structure has solved the defective that flexible connection structure is installed and dismounting is inconvenient effectively; Also reduce the rotating shaft difficulty of processing, kept collector ring tail end fan simultaneously, kept good cooling and dust collection capacity; This structural attachment point is positioned at collector ring to be surveyed, and is shorter than common insulating case, and cost is lower, and it is two far away from encoder, adopts the insulator joint pin, and easy to maintenance, security performance is higher.Adopt modularity access node structure, reliability is high, has been difficult for tide.

Fig. 1 is a kind of pin configuration generalized section of novel wind generator rotor;
Reference numeral: 1, rotating shaft, 2, the insulator joint pin, 3, the insulator sleeve, 4, collector ring, 5, the rubber positioning sleeve, 6, self-locking nut, 7, fan, 8, encoder.
Embodiment:
To combine accompanying drawing below, embodiment is done further to describe to the utility model.
A kind of pin configuration of wind power generator rotor; Comprise rotating shaft (1); Collector ring (4); Said rotating shaft (1) is provided with cavity, and cavity is equipped with the insulator sleeve (3) that is sintered into by hard copper wire and insulating material, and insulator sleeve (3) is provided with and is used for it is drawn the insulator joint pin (2) that is connected with collector ring with the rotor winding coil; The rubber positioning sleeve (5) that is used for fixing insulator sleeve (3) also is housed in the cavity, and the cavity opening part is provided with the self-locking nut (6) that is used for bore seal.Cavity in the middle of the rotating shaft (1) is about rotating shaft central axis symmetry.
The utility model is to sinter copper cash and insulating material into the insulation joint pin; Be connected with rotor coil and collector ring respectively with the insulation joint pin again; Structure has solved the defective that flexible connection structure is installed and dismounting is inconvenient effectively; Also reduce the rotating shaft difficulty of processing, kept collector ring tail end fan simultaneously, kept good cooling and dust collection capacity; This structural attachment point is positioned at collector ring to be surveyed, and is shorter than common insulating case, and cost is lower, and it is two far away from encoder, adopts the insulator joint pin, and easy to maintenance, security performance is higher.Adopt modularity access node structure, reliability is high, has been difficult for tide.
