Abstract
The utility model discloses an enamelled wire fixing structure in a generator rotor. The enamelled wire fixing structure comprises a rotor main shaft and a rotor punching sheet. The rotor punching sheet is fixed to the central portion of the rotor main shaft in a penetrated manner. An upper portion and a lower portion of the rotor punching sheet are respectively provided with grooves for winding enamelled wires. The edges of the two sides of the central portion of rotor punching sheet are respectively provided with openings. The rear ends of the openings facing the direction of the center of the rotor punching sheet are provided with bolt grooves. The nut ends of bolts are fixed in the bolt grooves of the rotor punching sheet. Pressing sheets are fixed to the screw ends of the bolts. With the enamelled wire fixing structure in the generator rotor of the utility model, the bolt grooves are arranged on the rotor punching sheet, the nut ends of the bolts are fixed in the bolt grooves, the nut ends of the bolts and nuts together fix the pressing sheets, and the pressing sheets fix the enamelled wires wound and arranged in the rotor punching sheet. In this way, the enamelled wire winding space in the rotor punching sheet is not occupied, and the generating efficiency of the generator is guaranteed. In addition, the pressing sheets can firmly fix the enamelled wires, and even when the generator rotor runs at high speed, the enamelled wires in the rotor can not be thrown out by a centrifugal force.
Description
Technical field
The utility model relates to generator rotor structure, relates in particular to the enamelled wire fixed structure in the generator amature.
Background technology
At present, small-sized the two poles of the earth synchronous generator rotor, its rotor main shaft middle part is arranged with rotor punching; For guaranteeing that the rotor winding is under the running up of 3000-3600rpm; Enamelled wire in the rotor does not get rid of outward that to cause enamelled wire to scrape disconnected, adopts dual mode to press enamelled wire usually: 1, as shown in Figure 1, reserve nut holddown groove 01 at rotor punching 02 middle part dual-side; This holddown groove 01 extends outward from rotor punching 02 middle part dual-side; It takies the outer space of enamelled wire around the home of rotor punching 02, cause enamelled wire around the home area reduce, thereby influence the power of generator.2, as shown in Figure 2; The rotor punching 02 dual-side edge T shape boss 03 that stretches out; Increased the area around the home of rotor punching 02 outer enamelled wire like this, after enamelled wire is good around the home, snapped in fixedly enamelled wire of 2mm thick fiber pressing plate outside the groove around the home from enamelled wire; When copper factor was less than normal, the fiber pressing plate was prone to come off like this; When copper factor was bigger than normal, fiber pressing plate difficulty was pressed into, and this rotor punching processing technology difficulty strengthens.
Summary of the invention
Enamelled wire fixation when the purpose of the utility model provides a kind of generator amature and runs up can also guarantee the enamelled wire fixed structure in the generator amature of generator efficiency simultaneously.
For realizing above-mentioned purpose, the enamelled wire fixed structure in a kind of generator amature of the utility model comprises rotor main shaft and rotor punching; Rotor punching wears and is fixed on the rotor main shaft middle part; The rotor punching upper and lower part is provided with the groove that twines enamelled wire respectively, is respectively equipped with opening on the dual-side of said rotor punching middle part, and open rearward end is provided with bolt slot towards the rotor punching center position; The nut end of bolt is fixed in the bolt slot of rotor punching, and the screw rod end of bolt is fixed with compressing tablet.
Said compressing tablet is located on the screw rod of bolt, and is fixed by nut.
Adopt the structure of the utility model, bolt slot is set in rotor punching, the nut end of bolt is fixed in the bolt slot, and the nut end of bolt and nut be fixing compressing tablet jointly, and compressing tablet is fixed the enamelled wire in rotor punching around the home.So neither take the enamelled wire space around the home in the rotor punching, guarantee the generating efficiency of generator, compressing tablet can fixedly secure enamelled wire in addition, even generator amature runs up, the enamelled wire in the rotor can not get rid of because of centrifugal force outward yet.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation:
Fig. 1 is first kind of structural representation of pushing down the rotor punching in the enamelled wire mode;
Fig. 2 is second kind of structural representation of pushing down the rotor punching in the enamelled wire mode;
Fig. 3 is the cutaway view of the enamelled wire fixed structure in the utility model generator amature;
Fig. 4 pushes down the structural representation of the rotor punching in the enamelled wire mode for the utility model.
Embodiment
Like Fig. 3 or shown in Figure 4; The utility model comprises rotor main shaft 1 and rotor punching 2, and rotor punching 2 wears and is fixed on rotor main shaft 1 middle part, and rotor punching 2 upper and lower parts are provided with the groove 3 that twines enamelled wire respectively; Be respectively equipped with opening 4 on the said rotor punching 2 middle part dual-sides; Opening 4 rear ends are provided with bolt slot 5 towards rotor punching 2 center positions, and the nut end 61 of bolt 6 is fixed in the bolt slot 5 of rotor punching 2, and the screw rod end 62 of bolt 6 is fixed with compressing tablet 7.
Said compressing tablet 7 is located on the screw rod 62 of bolt 6, and fixing by nut 8.
Adopt above structure; At the rotor punching middle part opening 4 is set, opening 4 rear ends are provided with bolt slot 5 towards rotor punching 2 center positions, and bolt slot 5 is located in the rotor punching 2 like this; Do not take in the rotor punching 2 space of enamelled wire around the home, thereby guarantee the efficient of generator.In addition; The nut end 61 of bolt 6 is fixed in the bolt slot 5 of rotor punching 2; Cooperate with bolt 6 screw rod ends by nut 8 compressing tablet 7 is fixed on outside the rotor punching 2; Enamelled wire in the rotor is fixed, and prevents that rotor from running up down, and the enamelled wire in the rotor gets rid of outward that to cause enamelled wire to scrape disconnected.
Claims (2)
1. the enamelled wire fixed structure in the generator amature; Comprise rotor main shaft and rotor punching, rotor punching wears and is fixed on the rotor main shaft middle part, and the rotor punching upper and lower part is provided with the groove that twines enamelled wire respectively; It is characterized in that: be respectively equipped with opening on the dual-side of said rotor punching middle part; Open rearward end is provided with bolt slot towards the rotor punching center position, and the nut end of bolt is fixed in the bolt slot of rotor punching, and the screw rod end of bolt is fixed with compressing tablet.
