Description
Technical field
The utility model relates to light-duty box technical field of generators, and what particularly simple, reasonable in design, the result of use of a kind of structure was good has winding stator core fixed structure.
Background technology
In prior art, winding stator core is had to be fixed with many kinds of methods in generator unit stator, light-duty box type electric generator has winding stator core fixing means generally to have two kinds, one adopts bolt and support to be connected and fixed, deviation is there is in the scale error that this fixing means is holed due to line to there being the location of winding stator core, restriction is existed to the adjustment of the power generator air gap uniformity, and short transverse needs adjustment pad to finely tune, and this fixing means easily causes motor oscillating problem because installation is not firm; Another kind method be utilize the method for machining to support dividing plate and have winding stator core end plate carry out seam coordinate be fixed, although this fixing means leans on the installing hole of coaxial processing and seam to ensure that the accuracy of the installation location of winding stator core, but needing to be worked into be greater than to support end plate opening size has winding stator core end plate external diameter winding stator core will be had to lift, moreover during assembling, need support lifting to erect winding stator core just can be had to compress into.Need in view of there being winding stator core to erect vertically to be pressed in support, just higher to the repeatedly pressure request of stator core, the pressure fixing reliability of this fixing means only by seam interference fit is not high yet, moreover operates inconvenient so yet.
Summary of the invention
For overcoming deficiency of the prior art, the utility model provides a kind of structure simple, rationally novel in design, what result of use was good has winding stator core fixed structure, avoid the Generator Vibration problem that winding stator core causes because of fixing instability, what realize that generator has winding stator core fixing is reliably convenient and swift, generator stator-rotator airgap uniformity degree when ensureing fixing, and fixing simple, accurate, firm, effectively extend the useful life of generator.
According to design provided by the utility model, one has winding stator core fixed structure, comprise support, be located at the stator core in support and internal thread distribution, front end-plate is provided with in support, end plate, front end-plate is positioned in support, dividing plate before support is provided with according to this between end plate, support median septum, support rear bulkhead, stator core is positioned at dividing plate before support, between support rear bulkhead, stator core is provided with stator core front end-plate, stator core dividing plate, stator core end plate, the end face of stator core front end-plate is provided with the seam matched with dividing plate end face before support, the end face of stator core end plate is provided with the seam matched with support rear bulkhead end face, before support, dividing plate end face and support rear bulkhead end face are provided with pilot hole, stator core front end-plate end face and stator core end plate end face are provided with and are connected and fixed hole, internal thread is promoted and is fixed on pilot hole and is connected and fixed in hole.
Above-mentioned, support median septum end face is provided with pilot hole, and stator core dividing plate end face is provided with and is connected and fixed hole, and pilot hole is fixed with being connected and fixed hole and being promoted by internal thread.
Above-mentioned, described internal thread is promoted as cylindrical pin with external thread.
The beneficial effects of the utility model:
The utility model novel in structural design, rationally, structure is simple, the fixing of interference fit is realized by both ends of the surface fixing structure, avoid the possibility that winding stator core axially produces displacement, and by internal thread promote fixing, effectively prevent the possibility that winding stator core radial circumference produces displacement, reach the effect to there being the winding stator core four-dimension fixing, fixing more accurate, safe and reliable, eliminate owing to there being the inaccurate generator stator-rotator non-uniform air-gap caused in winding stator core fixed position, solve because stator core installs the not firm Generator Vibration problem caused, effective reduction makes, processing, lifting difficulty, and applying flexible, convenient insurance, result of use is good.
accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the B-B cutaway view shown in Fig. 1.
embodiment:
Number in the figure 1 represents support front end-plate, label 2 represents generator pit, and label 3 represents dividing plate before support, and label 4 represents stator core front end-plate, label 5 represents stator core, label 6 represents support median septum, and label 7 represents stator core dividing plate, and label 8 represents internal thread and promotes, label 9 represents support rear bulkhead, label 10 represents stator core end plate, and label 11 represents support end plate, and label 12 represents pilot hole.
