Abstract
The utility model discloses a fastening device for the rotor coils of a generator, which comprises a rotor core. The rotor core is provided with more than two winding parts and each winding part is wound with a coil. The side part of each coil is provided with a field coil bracer through pressing. A stay bar is respectively arranged between every two adjacent field coil bracers, wherein the field coil bracers are pressed onto different coils. The fastening device can be used for pressing rotor coils. Due to the adoption of the fastening device, the separation of rotor coils from the rotor core due to the centrifugal force can be prevented.
Description
Technical field
The utility model relates to generator, especially the rotor of generator.
Background technology
Existing generator mainly comprises rotor and stator, and wherein, rotor comprises rotating shaft, rotor core and coil, and rotor core is installed in the rotating shaft, and coil winding is on rotor core; Stator comprises stator seat, silicon steel sheet and coil, and silicon steel sheet is fixed on the stator seat, and the coil holding is on silicon steel sheet; Described rotating shaft is installed on the stator seat by bearing.When the rotating shaft High Rotation Speed, coil on rotor core and the rotor core is also followed together High Rotation Speed, when the coil High Rotation Speed on the rotor core, can produce larger centrifugal force, fixing insecure such as coil, the phenomenon that coil breaks away from rotor core can appear, like this, just damage easily generator, even burn generator.
Summary of the invention
The purpose of this utility model provides a kind of fastener of electric generator rotor coil, and this fastener can be suppressed the coil of rotor coil, prevents from separating with rotor core because centrifugal force easily makes rotor coil.
For achieving the above object, a kind of fastener of electric generator rotor coil comprises rotor core, has the winding section more than two on the rotor core, is wound with coil on the winding section; Sidepiece at coil is suppressed with magnetic pole support block, is compressed between the adjacent pole bracer on the different coils and is provided with strut.
Said structure; by utilize a strut to support two magnetic pole support blocks in coil sides; with the sidepiece of coil being compressed on the winding section tightly; in case rotor core rotation; then most of component of the centrifugal force that produces of coil and the pressure in contrast of magnetic pole support block; effectively limited because centrifugal force makes coil and left rotor core, played the effect of protection generator.
As improvement, be extended with laterally fin on the magnetic pole support block.Because generator is in when work, rotor core and coil can produce a large amount of heats, by fin is set, can increasing heat radiation area, thus improved radiating efficiency, thus the useful life of generator can be improved.
As improvement, described strut is screw rod, is provided with adjusting nut at screw rod.This structure by the rotation adjusting nut, can be regulated the distance between the adjacent pole bracer that is compressed on the different coils, plays the effect of regulating magnetic pole support block suppressing coil pressure, simultaneously, also is convenient to install magnetic pole support block.

Fig. 1 is the installation diagram of generator.
Fig. 2 is the sectional structure chart of generator amature.
Fig. 3 is the structure chart of generator amature.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further elaborated.
As shown in Figure 1, generator comprises rotor and stator 10; Wherein, rotor comprises rotating shaft 1, rotor core 2 and coil 3, and rotating shaft 1 is installed on the stator 10 by bearing.As shown in Figures 2 and 3, has the winding section 21 more than two on the rotor core 2, the circumferential edges of winding section 21 is extended with flange 211 to circumferencial direction, the inner side edge of flange 211 and winding section 21 forms coil clamping groove 212, coil 3 is wound on the winding section 21, and the part holding of coil is in clamping groove 212, the coil outside of holding in clamping groove forms the sidepiece of coil, sidepiece at coil is suppressed with magnetic pole support block 4, be compressed between the adjacent pole bracer on the different coils and be provided with strut 5, by strut 5 two magnetic pole support blocks are propped up, make magnetic pole support block being compressed on the coil sides tightly, the effect because of centrifugal force of can preventing causes coil to fly out to damage generator or burns generator.
As shown in Figure 2, for improving the radiating efficiency of rotor core 2 and coil 3, on magnetic pole support block, be extended with laterally fin 41.
As shown in Figure 2, for the magnetic pole support block that is easy for installation and removal, and regulate distance between the adjacent pole bracer that is compressed on the different coils, strut is set to screw rod, is provided with adjusting nut 6 at screw rod, can reach above-mentioned effect by rotation adjusting nut 6.
