Abstract
The invention discloses an integrated ventilating type tooth support. The integrated ventilating type tooth support comprises an annular pressing ring, and a tooth support body which is prepared from metal material or nonmetal material; a plurality of screw mounting holes are formed in the pressing plate; the pressing ring and the tooth support body are integrally structured; a plurality of tooth support plates are arranged on the tooth support body; bulges are arranged at one of the sides of the tooth support plates, close to a stator/ rotor punch; the height of each bulge is gradually increased from inside to outside; a closing groove corresponding to a stator/ rotor punching groove is formed between every two tooth support plates. According to the integrated ventilating type tooth support, the integrated processing structure is adopted, thus the inaccurate deformation and positioning caused by welding can be avoided, and the processing quality can be improved; various ventilating channels can be formed through the structure as requirement, thus the air channels can be flexibly designed, and the problem of dispersing of teeth of the motor can be solved.
Description
Technical field
The invention belongs to motor ventilation technical field, be specifically related to a kind of novel integrated aeration type tooth support, this tooth support is suitable for that dimensional requirement is accurate, structure is firm, high, the easy-to-install motor of tooth support wind path structure adaptability.
Background technology
In motor, stator and rotor cores is formed by about 0.5mm silicon steel plate stacking, whole iron core forms a firm entirety by stretching screw, tooth support is positioned at stator-rotor iron core both sides end face, mainly contain two effects: one is two axial ends as stator-rotor iron core, coordinate trim ring will laminate iron core tension; One is extraction special wind path, cooling motor rotor end.
Under current motor compact type and heavy duty detergent Design trend trend, tooth pressboard structure must have the firm height of structure, easy-to-install feature.Meanwhile, its wind path structure also will can carry out larger adjustment in conjunction with overall wind path designing requirement, ensures the reasonable distribution of inner each wind path air quantity.
The tooth pressboard structure of existing motor is directly welded on one piece of thin plate measure-alike with core stamping by the strip blade with rotor groove number equal number, the trim ring of motor is pressed in the yoke portion of tooth support, axially penetrate stretching screw, electric machine iron core is linked to be an entirety.
There is following shortcoming in this structure: welding job amount is large; Welding deformation causes more greatly size to be difficult to ensure, installation deviation is larger; Trim ring and tooth support contact-making surface are difficult to ensure that the smooth thrust that causes is uneven; Trim ring is pushed down tooth support yoke portion and is caused between cog to scatter; Substantially do not consider mating of tooth support and overall wind path, even certain structures is scattered for preventing between cog, increases the height of blade, causes the short circuit of wind path.
Summary of the invention
The object of patent of the present invention is the shortcoming overcoming prior art, modified node method, take into account size, structure, performance of ventilating three aspect requirement, provide that a kind of structure is simple, good manufacturability, the integral type aeration type tooth support that can adapt to wind path adjustment in conjunction with overall air-conditioning requirement.
The technical solution adopted for the present invention to solve the technical problems is: a kind of integral type aeration type tooth support, comprise the tooth support body of ring-type trim ring and metal material or nonmetallic materials, trim ring offers multiple screw rod installing hole, described trim ring and tooth support body are integral type structure, tooth support body is provided with multiple tooth pressing plates, tooth pressing plates is provided with lug boss near the side of rotor/stator punching, described lug boss outwards highly progressively increases, the closed slot corresponding with rotor/stator punching groove is formed between adjacent two tooth pressing plates
Described a kind of integral type aeration type tooth support, its trim ring is whole circle integral molding.
Described a kind of integral type aeration type tooth support, to be that integral type is shaping or distinguish is fan-shaped combine its tooth support body.
Described a kind of integral type aeration type tooth support, the face, one or both sides of its tooth support body is provided with air channel.
Described a kind of integral type aeration type tooth support, its air channel is straight air channel or curved air channel.
The invention has the beneficial effects as follows: adopt integral type processing structure, avoid and weld the distortion that brings and location is inaccurate, improve crudy, its structure can form various air duct as required, wind path is designed more flexible, the problem that motor between cog scatters can be solved, in a word, compared with existing motor tooth support pattern, the present invention can significantly improve reliability, the simultaneously optimal design of motor component production technology quality and product.
Accompanying drawing explanation
Fig. 1 is the structural representation of stator tooth pressing plate of the present invention;
Fig. 2 is the cutaway view in A-A direction in Fig. 1.
Each Reference numeral is: 1-trim ring, 2-tooth support body, 3-tooth pressing plates, 4-lug boss.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
With reference to Fig. 1, shown in Fig. 2, the invention discloses a kind of integral type aeration type tooth support, comprise the tooth support body 2 of ring-type trim ring 1 and metal material or nonmetallic materials, trim ring 1 offers multiple screw rod installing hole, described trim ring 1 and tooth support body 2 are integral type structure, wherein trim ring 1 is whole circle integral molding, tooth support body 2 combines for integral type is shaping or distinguish is fan-shaped, can by machining, also can by processing again after casting, two end faces of tooth support, perforate is all passed through processing and is ensured dimensional accuracy, to ensure to fit with iron core uniform close, tooth support body 2 is provided with multiple tooth pressing plates 3, tooth pressing plates 3 is provided with lug boss 4 near the side of rotor/stator punching, described lug boss 4 outwards highly progressively increases to form between cog ramp structure, the problem that can effectively prevent between cog from scattering, described between cog ramp structure can be that gradually open form formula also can be reduced to the protuberance being arranged on teeth portion, namely directly projective structure is added in teeth portion, it is allowed to have adjustment wind path, the function that anti-between cog scatters, designed by the incline structure in this local area, an opposite force can be formed, tooth is all compressed, can not stick up, the closed slot corresponding with rotor/stator punching groove is formed between adjacent two tooth pressing plates 3, the face, one or both sides of tooth support body 2 is provided with air channel, tooth support can be arranged on as required near trim ring side or near iron core side, thus adjustment wind path structure, air channel is straight air channel or curved air channel, or other arbitrary shape air channels, because trim ring 1 and tooth pressing plates 3 unite two into one, and all size can be processed into as requested, various shape, motor air channel can be processed into arbitrary shape and size according to general requirement, ensure that the enforcement of various design wind path.
Above-described embodiment is illustrative principle of the present invention and effect thereof only; and the embodiment that part is used, for the person of ordinary skill of the art, without departing from the concept of the premise of the invention; can also make some distortion and improvement, these all belong to protection scope of the present invention.
