According to the utility model, the damage to the surface of the pole shoe is small, so that the sine voltage waveform distorsion rate of the motor can reach the national standard.
Description
[technical field]
The utility model relates to a kind of electrical generator fields, particularly a kind of salient-pole synchronous generator rotor magnetic pole fixed structure.
[background technology]
High rotating speed salient-pole synchronous generator is subjected to the restriction of the strength of materials, and generator amature is the company's of employing body magnetic yoke structure often, i.e. pole body and yoke monobloc forging structure, fixing just necessary the adopt pole shoe and the pole body fastening structure of pole coil at this moment.Traditional fixed form is that pole shoe and pole body directly are screwed, screw need bear the tension stress under pole coil, the pole shoe centrifugal action, and nut bears its compression and shear stress, so the quantity of screw is many, spiral shell footpath is big, and nut and pole shoe will have enough contacts area.Certainly will cause pole shoe surface counterbore area big like this, surface configuration is destroyed serious, has a strong impact on the voltage waveform of generator output, and intensity can not guarantee fully that sometimes for proof strength, required screw material difficulty again finds.
Be existing power generator rotor magnetic pole fixed structure as Fig. 1: the pole shoe 1 ' of crown shape, pole core 2 ', screw 3 ', pole coil 4 ' four are partly formed, pole shoe 1 ' is not locked screw 5 ' with pole core 2 ' by one and is connected, and described pole shoe 1 ' adopts direct screw 3 ' to fix with pole core 2 '.Because the centrifugal force of high-speed electric expreess locomotive is big, the diameter of the screw 3 ' that needs is big, the head of screw 3 ' is also big, so the surperficial counterbore of described pole shoe 1 ' is big, influence the voltage-form distortion rate of high-speed electric expreess locomotive, in order to guarantee the intensity of screw 3 ', required screw 3 ' material is difficult to again find, the need special steel that has, the cost height.
[utility model content]
The technical problems to be solved in the utility model is to provide a kind of salient-pole synchronous generator rotor magnetic pole fixed structure, and it can be little to the surface breakdown of pole shoe, makes generator sinusoidal voltage irregularity of wave form can reach national standard.
The utility model is achieved in that
A kind of salient-pole synchronous generator rotor magnetic pole of the utility model fixed structure, it comprises pole shoe, pole core, screw, pole coil, described pole shoe is the broach shape, described pole core is and the corresponding broach shape of described pole shoe, described pole coil is enclosed within outward on the described pole core, described pole shoe embeds the upper end of described pole core, and uses described screw.
Further, described screw is arranged in the longitudinal seam of two broach shapes.
Further, described screw comprises at least one screw and at least one screw of locking admittedly do not locked.
Advantage of the present utility model is:
1, pole shoe of the present utility model and pole core adopt the broach shape to cooperate, and utilize the method for junction of the edges of two sheets of paper screw to fix, so the nut of screw only need be bigger than screw rod, and the surface breakdown of described pole shoe is little, and generator sinusoidal voltage irregularity of wave form can reach national standard;
2, the utility model uses junction of the edges of two sheets of paper screw, and the longitudinal shearing stress that it bears is relatively little, and screw diameter is relatively little, and material easily selects, and intensity is reliable, the coefficient of safety height;
3, the utility model pole shoe and pole core adopt the broach shape to cooperate, and so also can play circumferential positioning action, and guaranteeing can circumferential misalignment influence insulation.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is the cutaway view of existing power generator rotor magnetic pole fixed structure one embodiment.
Fig. 2 is the cutaway view of the utility model one embodiment.
[embodiment]
See also shown in Figure 2ly, embodiment of the present utility model is described in detail.
As Fig. 2, it comprises the utility model one embodiment pole shoe 1, pole core 2, locks screw 3, pole coil 4 admittedly, and described pole shoe 1 is not locked screw 5 with pole core 2 by one and is connected.Described pole shoe 1 is the broach shape, described pole core 2 is and described pole shoe 1 corresponding broach shape, described pole coil 4 outer being enclosed within on the described pole core 1, described pole shoe 1 embeds the upper end of described pole core 2, and with described to lock screw 3 admittedly fixing, described method of locking screw 3 employing junction of the edges of two sheets of paper screws is admittedly passed from the longitudinal seam of two broach shapes.Described pole shoe 1 newly is designed to junction of the edges of two sheets of paper screw with pole core 2, promptly bore tapping together at the broach mating surface, the longitudinal length direction of locking screw 3 this moment is admittedly born the shear stress of the centrifugal force generation of pole shoe 1 and pole coil 4, can determine to lock admittedly the size of screw 3 and the length that two broach cooperate according to the size of shear stress.Therefore the nut of locking screw 3 admittedly only plays the role of positioning, and nut only needs to get final product than screw rod is bigger, and described pole shoe 1 surface breakdown is smaller.
Operating process: described magnetic pole pole shoe 1 matches with pole core 2, and compress with special fixture, at pole shoe 1 surperficial two ends two alignment pins that drill and ream, and alignment pin loaded onto, urgent, brill is attacked, Deng twist bit attack finish after, pole shoe 1 is sling, and removing iron is cut, burr, cleans the member apertures of all required assemblings.Coil supporting plate, core insulation are solidified into holistic pole coil 4 are inserted in pole core 2, adjust the height of pole coil 4, qualified back puts magnetic pole pole shoe 1, load onto alignment pin, and compress with special tooling, lock solid lock screw 3 by technological requirement, pole coil 4 through withstand voltage qualified after, the head of locking screw 3 is admittedly welded and gets final product.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented according to this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model contains.
