Description
Technical field
The invention belongs to motor ventilation technical fields, and in particular to a kind of novel integrated aeration type tooth support, the tooth pressure
Plate is suitable for the motor that size requirement is accurate, structure is firm, tooth support wind path structure adaptability is high, is easily installed.
Background technology
In motor, stator and rotor cores are formed by 0.5mm or so silicon steel plate stackings, and entire iron core is formed by stretching screw
One firm entirety, tooth support are located at stator-rotor iron core both sides of the face, and main there are two act on：First, as stator-rotor iron core
Two axial end faces, cooperation trim ring will laminate iron core tension；First, a special wind path is drawn, cooling electric machine rotor end
Portion.
Under current motor compact type and heavy duty detergent Design trend trend, tooth pressboard structure must have the structure firm high, easily
In installation the characteristics of.Meanwhile wind path structure will also combine overall wind path design requirement can carry out larger adjustment, in guarantee
The reasonable distribution of each wind path air quantity in portion.
The tooth pressboard structure of existing motor by the strip blade of quantity identical with rotor slot number be directly welded at one piece with
On the identical thin plate of core stamping size, the trim ring of motor is pressed in the yoke portion of tooth support, axially penetrates stretching screw, by motor iron
Core is linked to be an entirety.
The structure has the following disadvantages：Welding job amount is big；Welding deformation is larger to cause size to be difficult to ensure that, installation deviation
It is larger；Trim ring and tooth support contact surface, which are difficult to ensure that, smooth causes pressing force uneven；Trim ring, which pushes down tooth support yoke portion, leads between cog
It scatters；Substantially it is to prevent between cog from scattering not account for the matching of tooth support and overall wind path or even certain structures, increases blade
Height, lead to the short circuit of wind path.
Invention content
The shortcomings that aiming to overcome that the prior art of patent of the present invention, improved structure take into account size, structure, air permeability
It can be required in terms of three, a kind of simple in structure, good manufacturability is provided, can adjust the one adapted to wind path with reference to overall air-conditioning requirement
Formula aeration type tooth support.
The technical solution adopted by the present invention to solve the technical problems is：A kind of integral type aeration type tooth support, including ring
The tooth support ontology of shape trim ring and metal material or nonmetallic materials offers multiple screw rod mounting holes on trim ring, described
Trim ring and tooth support ontology are an integral structure, and tooth support ontology is equipped with multiple tooth pressing plates, and tooth pressing plates are rushed close to rotor/stator
The side of piece is provided with lug boss, and the lug boss is highly stepped up outward, is formed between two neighboring tooth pressing plates and fixed
Son/corresponding the closed slot of rotor punching slot,
A kind of integral type aeration type tooth support, trim ring are whole circle integral molding.
A kind of integral type aeration type tooth support, tooth support ontology for integral type be molded or divide valve sector combine and
Into.
A kind of integral type aeration type tooth support, the one or both sides face of tooth support ontology are equipped with air duct.
A kind of integral type aeration type tooth support, air duct are straight air duct or curved air duct.
The beneficial effects of the invention are as follows：Structure is processed using integral type, the next deformation of welded bands is avoided and positioning is inaccurate,
Processing quality is improved, structure can form various ventilating ducts as needed, make wind path design more flexible, can solve motor
The problem of between cog scatters, in short, compared with existing motor tooth support pattern, the present invention can significantly improve motor component production technology
Quality and the reliability of product, simultaneously optimization design.
Description of the drawings
Fig. 1 is the structure diagram of stator tooth support of the present invention；
Fig. 2 is the sectional view in A-A directions in Fig. 1.
Each reference numeral is：1-trim ring, 2-tooth support ontology, 3-tooth pressing plates, 4-lug boss.
Specific embodiment
The present invention is described in further detail below in conjunction with the accompanying drawings.
It is shown in reference picture 1, Fig. 2, the invention discloses a kind of integral type aeration type tooth support, including cyclic annular trim ring 1 and
The tooth support ontology 2 of metal material or nonmetallic materials offers multiple screw rod mounting holes, the trim ring 1 and tooth on trim ring 1
Pressing plate ontology 2 is an integral structure, and wherein trim ring 1 is whole circle integral molding, and tooth support ontology 2 is molded for integral type or divides valve
Sector is composed, can be by machining, can also be by being processed again after casting, and two end faces of tooth support are opened
Hole all ensures dimensional accuracy by processing, and to ensure to be bonded with iron core uniform close, tooth support ontology 2 is equipped with multiple tooth pressing plates
3, tooth pressing plates 3 are provided with lug boss 4 close to the side of rotor/stator punching, the lug boss 4 be highly stepped up outward with
The problem of forming between cog ramp structure, between cog being effectively prevent to scatter, the between cog ramp structure can be gradually open form formula
It can be reduced to be arranged on the protrusion of teeth portion, i.e., it be allowed to have and adjusts wind path, anti-between cog directly plus projective structure in teeth portion
The function of scattering is designed by the incline structure in this local area, can form an opposite force, tooth all be compressed, no
It can stick up, formation closed slot corresponding with rotor/stator punching slot between two neighboring tooth pressing plates 3, the one of tooth support ontology 2
Side or two sides are equipped with air duct, can be arranged as required in tooth support close to trim ring side or close to iron core side, thus
Wind path structure is adjusted, air duct is straight air duct or curved air duct or other arbitrary shapes air duct, since trim ring 1 and tooth pressing plates 3 close two
It is one, and can be according to requiring to be processed into various specifications, variously-shaped, motor air channel can be processed into arbitrarily according to general requirement
Shape and size, it is ensured that the implementation of various design wind paths.
The embodiment that the above-described embodiments merely illustrate the principles and effects of the present invention and part uses, for
For those of ordinary skill in the art, without departing from the concept of the premise of the invention, can also make it is several deformation and
It improves, these belong to protection scope of the present invention.
