Abstract
The utility model provides an installation fixing fixture of double-permanent-magnet power frequency brushless synchronous generator magnetic shoes, which comprises a circular ring, bolts and positioning pins. Threaded hole groups are drilled on the circular ring, the number of the threaded hole groups is the same as that of poles of a generator, the number of threaded holes in each threaded hole group is two times of that of permanent magnet blocks of each pole on the circumference, the bolts are mounted in each of the threaded holes, two or four positioning pins for fixing a fixture ring are arranged on the inner side of the circular ring, the positions of the positioning pins are located at the positions among rotor poles, and the circular ring, the bolts and the positioning pins are all made of non-magnetic conductive materials. By means of the technical scheme, the installation fixing fixture of the double-permanent-magnet power frequency brushless synchronous generator magnetic shoes is simple in structure, reasonable in design and easy to process and manufacture. The double-permanent-magnet power frequency brushless synchronous generator magnetic shoes are simple and convenient in installation fixing method and high in installation reliability, thereby avoiding potential safety hazard existing in the operation of the generator.

Embodiment
To combine accompanying drawing that the utility model is done further detailed description below: present embodiment provided detailed execution mode, but the protection range of the utility model is not limited to following embodiment being to implement under the prerequisite with the utility model technical scheme.
Like Fig. 1～shown in Figure 8; A kind of pair of related permanent magnetism power frequency no-brush synchronous generator magnetic shoe of present embodiment installs and fixes frock; Comprise annulus 1, bolt 2 and angle 3, on annulus 1, be drilled with the screwed hole group with the number of poles equal number of generator, each Kong Zuzhong screwed hole quantity is two times of quantity of the permanent magnet blocks of every utmost point on circumference; Bolt 2 is housed in each screw; The inboard of annulus 1 is provided with the angle 3 of two or four (corresponding two-pole machine or four utmost point motors) fixing tool rings, position between rotor pole, the position of angle 3, and the material of said annulus 1, bolt 2 and angle 3 is non-magnet material.Said non-magnet material is copper or stainless steel.
The inboard of said annulus 1 is provided with the angle 3 of four fixing tool rings.
The two permanent magnetism power frequency no-brush synchronous generator magnetic shoes of the utility model install and fix tool structure and see Fig. 1 and Fig. 2; It is made with non-magnet material (copper or stainless steel); Its structure is the screwed hole group that on an annulus, is drilled with equal number by the number of poles of generator; Each Kong Zuzhong screwed hole quantity is 2 times of quantity of the permanent magnet blocks of every utmost point on circumference, each screw centrally aligned permanent magnet blocks; Stainless steel or brass bolt are housed in each screw; Each bolt tail can be equipped with the hard rubber cover; This bolt is used to tighten up the usefulness of magnetic shoe (permanent magnet).
During use, it is good to encircle with bolt earlier, the position that makes ring rotor axially on be in the centre position of every block of magnetic shoe; Be equipped with the quantity that this magnetic shoe installs and fixes frock by permanent magnet axial permanent magnetic body number.
It is rotor magnetic shoe and the utility model that aims at two permanent magnetism power frequency no-brush synchronous generators of assembling easily and reliably that the two permanent magnetism power frequency no-brush synchronous generator magnetic shoes of the utility model install and fix frock.
The above; Be merely the preferable embodiment of the utility model; These embodiments all are based on the different implementations under the utility model general idea, and the protection range of the utility model is not limited thereto, and any technical staff who is familiar with the present technique field is in the technical scope that the utility model discloses; The variation that can expect easily or replacement all should be encompassed within the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with the protection range of claims.
