Technical field
The present invention relates to electrical micro-machine and make the field, particularly relate to a kind of novel series excited machine double insulating structure.
Background technology
Series excited machine is widely used in various electric tools, dust catcher, various occasions such as household electrical appliance; Two insulation are insulation systems of a kind of motor; Being applied to some takes place to puncture on the Danger Electric shock risk property high product; Increase one deck supplementary insulation between rotor core and the rotating shaft, and the basic insulation between original rotor core and the enamelled wire is called double insulation altogether.The withstand voltage standard of supplementary insulation, 3000V, 1s reveals voltage < 5mA.
Supplementary insulation all is with the mode that BMC (unsaturated polyester (UP) BMC) material is annotated through injection moulding or pressure itself and rotating shaft to be bonded together for a long time. the defective of prior art:
1, because this craft precision is lower, ready-made rotating shaft must be passed through secondary grinding processing just can meet the requirements of precision (dimensional tolerance, centre bore beats etc. relatively);
2, injection moulding or press to annotate possibility that there is lack of fill in BMC or lacks material can cause high-voltage breakdown, and this unreliability is not easy to detect because the detection in manufacture course of products can be beaten several sub-high pressures, during also might cause puncture;
3, need increasing smog that the injection-moulding device injection moulding produces has certain pollution, the particularly plant area chaotic state in which corrupt practices prevail that can become to influence ordinary production to environment, and particularly summer, the employee was unwilling to do this procedure;
4, increase the difficulty of production management, the operation increase can cause extra product quality problem, if outer processing has also increased the workload of buying outsourcing service and the transfer of parts;
5, new product development just needs new die sinking tool as long as need change in the slightly different or development process of size, and cost is high, changes the mould difficulty and is prone to cause waste.
Summary of the invention
It is simple that the technical problem that the present invention mainly solves provides a kind of technology, and precision is high, the novel series excited machine double insulating structure that integrated cost is low.
For solving the problems of the technologies described above; The technical scheme that the present invention adopts is: a kind of novel series excited machine double insulating structure is provided; Comprise: rotating shaft, insulating sleeve, iron core, said insulating sleeve is coaxial to be assemblied in the said iron core endoporus, and said rotating shaft is with being located in the said insulating sleeve; Be equipped with the insulation commutator in the said rotating shaft, be provided with insulation system between said insulation commutator one end face and the rotating shaft.
In preferred embodiment of the present invention, be matched in clearance between said insulating sleeve and the iron core endoporus.
In preferred embodiment of the present invention, between said rotating shaft and the insulating sleeve interference fit.
In preferred embodiment of the present invention, said rotating shaft is provided with guide section.
In preferred embodiment of the present invention, said insulation system is the wool felt structure.
In preferred embodiment of the present invention, said iron core two ends are respectively fitted with insulating end plate.
The invention has the beneficial effects as follows: the novel series excited machine double insulating structure of the present invention operation is simple, directly rotating shaft, iron core, three parts outsourcings of axle insulating case is returned to assemble and can be accomplished; Precision is high, and insulating sleeve is the mill process component, and it is little to beat; Improve airgap uniformity degree, improve motor performance and homogeneity of product, the course of processing does not influence environment; Product development is simpler, and insulating sleeve length is cut, and can arbitrarily change, and particularly the change in the product development process can not cause scrapping of mould, has economy more; Integrated cost is lower, along with the further raising of insulating sleeve technology, and mass production, integrated cost has reduced more, and is lower than traditional approach cost; The finished product insulating sleeve adopts glass fiber establishment final vacuum dipping H level (180 ℃) epoxy resin after the hot setting moulding, forms densification and the structure of toughness has promptly guaranteed insulation property, has also to a certain degree increased the rigidity of axle, good reliability.
Description of drawings
Fig. 1 is the structural representation of novel series excited machine double insulating structure one preferred embodiment of the present invention;
Fig. 2 is the explosive view of novel series excited machine double insulating structure shown in Figure 1;
The mark of each parts is following in the accompanying drawing: 1, rotating shaft, 2, insulating sleeve, 3, iron core, 4, insulating end plate, 5, guide section, 6, the insulation commutator, 7, insulation system.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
See also Fig. 1 and Fig. 2, the embodiment of the invention comprises:
A kind of novel series excited machine double insulating structure comprises: rotating shaft 1, insulating sleeve 2, iron core 3, and said insulating sleeve 2 coaxial being assemblied in said iron core 3 endoporus, said rotating shaft 1 is with being located in the said insulating sleeve 2.Said iron core 3 two ends are respectively fitted with insulating end plate 4.
Wherein insulating sleeve 2 is the insulating sleeves 2 that adopt glass fiber and resin to process.Insulating sleeve 2 is the mill process component, and it is little to beat, and precision is high.
Between said insulating sleeve 2 and iron core 3 endoporus is matched in clearance.Be interference fit between said rotating shaft 1 and the insulating sleeve 2.Assembling process is to use special-purpose press-fitting tool, earlier iron core 3 is put into frock, then insulating sleeve 2 is inserted iron core 3 endoporus also by on earth, then rotating shaft 1 is assemblied in the said insulating sleeve 2, promptly accomplishes assembling.
