So, effectively solved the rotor coil and taken off the problem that throws away high -speed rotatory in -process coil pine, and it is good to prevent getting rid of the intensity of device, the reliability is high, easily makes installation convenient operation.
Description
Technical field
The utility model relates to a kind of throwing prevention device, is specifically related to a kind of high-speed rotary motor coil throwing prevention device.
Background technology
At present, be no matter that in generator or motor, rotor is rotating parts, gap between rotor is very little, and epitrochanterian each parts must be fixed reliably, prevents the reason of centrifugal force and electromagnet pull from causing parts to loosen, being out of shape, thus cause rotor friction, cause fault.
Coil is part main on rotor, needs to adopt various measures fixing, particularly to high-revolving motor, and coil fixing very important.This just needs that a kind of intensity is good, reliability is high, be easy to manufacture, fitting operation easily coil throwing prevention device fix rotor coil, getting loose at high-speed rotation coil with preventing rotor throws away.
Utility model content
In view of the defect that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of high-speed rotary motor coil throwing prevention device, efficiently solves rotor coil and to get loose the problem thrown away at high-speed rotation coil.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of high-speed rotary motor coil throwing prevention device, comprise screwed hole bracer, blind hole bracer, double threaded screw and two nuts, described screwed hole bracer is arranged in one of them of two groups of adjacent coils, described blind hole bracer is arranged on wherein another of two groups of adjacent coils, and described screwed hole bracer and described blind hole bracer are oppositely arranged, described screwed hole bracer is provided with screwed hole, described blind hole bracer is provided with blind hole, described screwed hole bracer is connected together with two nuts by described double threaded screw with blind hole bracer.
The beneficial effects of the utility model are: efficiently solve rotor coil and to get loose the problem thrown away at high-speed rotation coil, and the intensity of this throwing prevention device is good, reliability is high, and be easy to manufacture, fitting operation is convenient.
Further, described screwed hole bracer and described blind hole bracer are made up of aluminum.

Embodiment
Be described principle of the present utility model and feature below in conjunction with accompanying drawing, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
Refer to Fig. 1 to Fig. 4, it is depicted as the high-speed rotary motor coil throwing prevention device structural representation in use that the utility model provides.Particularly, in use, this rotor is provided with four groups of coils to this throwing prevention device, i.e. the first coil 5, second coil 6, tertiary coil 7 and the 4th coil 8.Wherein the first coil 5 is adjacent with the second coil 6, and tertiary coil 7 is adjacent with the 4th coil 8, the axes normal of the first coil 5 and the second coil 6, the axes normal of tertiary coil 7 and the 4th coil 8.
This high-speed rotary motor coil throwing prevention device is arranged between two groups of adjacent coils.In the present embodiment, between two groups of adjacent coils, correspondence is provided with two throwing prevention devices.
Below, be described for the first coil 5 and the second coil 6.Each high-speed rotary motor coil throwing prevention device comprises screwed hole bracer 1, blind hole bracer 2, double threaded screw 4 and two nuts 3.In the present embodiment, screwed hole bracer 1 is arranged on the first coil 5, and blind hole bracer 2 is arranged on the second coil 6, and screwed hole bracer 1 and blind hole bracer 2 are oppositely arranged.Screwed hole bracer 1 is provided with screwed hole, and blind hole bracer 2 is provided with blind hole, and screwed hole bracer 1 is connected together with two nuts 3 by double threaded screw 4 with blind hole bracer 2.
Installation method is particularly: one end of double threaded screw 4 is screwed after on screwed hole bracer 1, fastening with nut 3, the other end of double threaded screw 4 puts another nut 3, be deep in blind hole bracer 2, again screwed hole bracer 1 and blind hole bracer 2 are snapped between two adjacent line group circles, tighten the nut 3 at blind hole bracer 2 place, thus utilize active force and reaction force the first coil 5 and the second coil 6 to be pressed on rotor core.The installation method of the throwing prevention device between tertiary coil 7 and the 4th coil 8 is identical, does not repeat them here.
In addition, screwed hole bracer 1 and blind hole bracer 2 are made up of aluminum, so, lightweight, and heat conduction is fast, is conducive to the ventilation and heat of coil.
The utility model owing to being provided with high-speed rotary motor coil throwing prevention device between adjacent two groups of coils, and so, can prevent rotor coil from getting loose at high-speed rotation coil and throw away, and intensity is good, reliability is high, is easy to manufacture, and fitting operation is convenient.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
