Embodiment
Below in conjunction with description of drawings one embodiment of the invention.
Fig. 1 illustrates a core body 1 of the present invention's one low noise reactor.This core body 1 comprises a plurality of stacked steel plate 11, has on the steel plate through gap pad 12 surperficial 11a against each other.
Each stacked steel plate 11 is laminated by a plurality of basic U-shaped steel plate layers (steel layer).Be impregnated with lacquer on the stacked steel plate 11, thereby the steel plate layer is bonded together mutually by impregnating varnish.
Also epoxy available system or acrylic acid series impregnated with adhesive replacement impregnating varnish are sticky together the steel plate layer.
Each the gap pad 12 that is inserted between the stacked steel plate 11 abutment face 11a can be made as pottery, glass, glass epoxide matrix etc. by non magnetic insulating part.
The abutment face 11a of stacked steel plate 11 and gap pad 12 usefulness epoxies system or acrylic acid series binding agent cement mutually.
Preferably, the be adhesively fixed hardness of binding agent of abutment face 11a and gap pad 12 is that Shore hardness (D level) value is equal to or greater than 80.
Also can not insert gap pad 12 between the abutment face 11a and directly against each other, bond together.
The structure of core body 1 as mentioned above.Shown in Fig. 2 (a), still be stained with impregnating varnish 15 on the abutment face 11a with the stacked steel plate 11 of coating with lacquer dipping.
When the bonding abutment face 11a that is stained with impregnating varnish 15 on it and gap pad 12 or adhered to one another when being stained with the abutment face 11a of impregnating varnish 15 on it, because the cohesive force between impregnating varnish 15 and the binding agent is low, so its adhesion strength is also low.
Therefore, be heated ringing or when impacting of core body between abutment face 11a and the gap pad 12 or the deterioration of the binding part between the abutment face 11a or destroyed, thereby causes noise by the vibration that electromagnetic attraction causes.
Therefore,, remove the impregnating varnish 15 on the stacked steel plate 11 abutment face 11a, make abutment face 11a expose behind the metal covering metal abutment face 11a and binding agent chemical bonding together, thereby improve adhesion strength according to low noise reactor of the present invention shown in Fig. 2 (b).
The following describes the method that stacked steel plate 11 abutment face 11a go up the impregnating varnish of adhesion of removing.
Fig. 3 and 4 illustrate one remove abutment face 11a go up adhesion impregnating varnish remove lacquerware 21.
Should remove lacquerware 21 and comprise having an its roller elements 22 and that is used as the metal plug 22a of grinding parts to drive the motor 23 that this its roller elements 22 is rotated on its outer peripheral face.This rotation metal plug 22a contacts the abutment face 11a of the stacked steel plate 11 on the clamper 24, thereby removes the impregnating varnish that abutment face 11a goes up adhesion.
This metal plug 22a that its hardness is equal to or less than the hardness of stacked steel plate 11 for example makes with the wire of hardness between brass and iron.
Its roller elements 22 goes up in the direction (horizontal direction among Fig. 3) vertical with the stacked direction (vertical direction among Fig. 3) of stacked steel plate 11 and rotates.Therefore, metal plug 22a removes impregnating varnish along the folded steel plate 11 of laminated steel flaggy contact layer.
The rotating speed of its roller elements 22 for example is set to 1000rpm-2000rpm.
Owing to as above construct metal plug 22a and its roller elements 22, therefore only selection is removed impregnating varnish and is not damaged stacked steel plate 11 or cause short circuit between steel plate, thereby prevents that loss and heating from increasing.
Owing to the increase of the loss that prevents to be caused by short circuit between the steel plate, therefore special fuel efficiency in vehicle improves.
As shown in Figure 5, except its roller elements 22 is rotated on the direction vertical with the stacked direction of stacked steel plate 11, stacked steel plate 11 clampers 24 placed on it can move on the direction vertical with the stacked direction of stacked steel plate 11.
Shown in Fig. 2 (a), between the steel plate layer of stacked steel plate 11 gapped (end difference).Just can remove impregnating varnish in the gap effectively at short notice reliably along steel plate layer moving metal silk brush 22a.
With chuck 25 stacked steel plate 11 is fixed on the clamper 24.An one end 24a of clamper 24 parts that stacked steel plate 11 is placed on it and an end 25a of chuck 25 stretch out dimension D 1 and D2 from the abutment face 11a of stacked steel plate 11 respectively to metal plug 22a.
Because this end 24a of clamper 24 and this end 25a of chuck 25 stretch out from abutment face 11a as mentioned above, prevent that therefore the power that metal plug 22a acts on the abutment face 11a from causing each steel plate layer to peel off and stacked steel plate 11 distortion when removing impregnating varnish.
Dimension D 1 and D2 for example are set at about 0.1-0.5mm.
A plurality of stacked steel plate 11 that impregnating varnish on its abutment face 11a is removed as mentioned above are placed to abutment face 11a through gap pad 12 against each other.Then, as shown in Figure 6, fill up binding agent 16 after-hardening between each abutment face 11a of stacked steel plate 11 and each the gap pad 12, thereby constitute its abutment face 11a and the firm mutually core body 1 that bonds of gap pad 12.
Binding agent 16 firmly sticks together the metal abutment face 11a and the gap pad 12 that expose.Thereby prevent that stacked steel plate 11 and gap pad 12 are subjected to attraction and the magnetostrictive stress that is caused by magnetic flux change in the magnetic circuit, thereby prevent to vibrate or run foul of each other.Thereby reduce the noise of core body 1.
Also can prevent by thermal cycle and impact the degeneration cause, thereby prevent that noise from becoming big as time passes.
Preferably, binding agent 16 is applied to abutment face 11a go up with the coating abutment face 11a gross area 80% or more than.In addition, binding agent 16 preferably is coated with the gross area of abutment face 11a.
It is the reasons are as follows.
Be not coated with the gross area of abutment face 11a as binding agent 16, between whole abutment face 11a and gap pad 12, will generate the space that wherein is not coated with binding agent 16.Then, stress concentrates on the steel plate layer that has the space, causes this steel plate layer displacement.Therefore this steel plate layer collides gap pad 12, thereby generates very big noise.
But, when binding agent 16 is covered with on the whole area at abutment face 11a and does not have the space, binding agent 16 alleviates and the attraction that disperses to be caused by magnetic flux change or magnetostriction cause and act on stress on stacked steel plate 11 and the gap pad 12, thereby suppresses vibration.
The following describes a core body of reactor of the present invention.
The core body 50 of reactor shown in Figure 8 comprises a plurality of through tabular gap pad 63 stacked steel plate unit 51 against each other.
Each stacked steel plate unit 51 comprises one by the folded layer by layer U-shaped stacked steel plate that forms 61 of a plurality of U-shaped steel plates with each is by the folded layer by layer I shape stacked steel plate 62 that forms of a plurality of I shape steel plates.I shape stacked steel plate 62 through corresponding tabular gap pad 63 against U-shaped stacked steel plate 61.
The above-mentioned lacquerware 21 that removes is removed the impregnating varnish on the abutment face 62a of the abutment face 61a of U-shaped stacked steel plate 61 and I shape stacked steel plate 62 and is exposed its metal covering.Then, above-mentioned binding agent 16 bonds to gap pad 63 to abutment face 61a and and abutment face 62a is bonded on the gap pad 63.
Resin bobbin 64 is enclosed within on the periphery of U-shaped stacked steel plate 61 and I shape stacked steel plate 62 connecting portions.
Resin bobbin 64 is integrally molded with U-shaped stacked steel plate 61 and I shape stacked steel plate 62 in the mould that is placed on a moulded resin bobbin 64 after gap pad 63 is adhered to one another.
Then, thereby with the abutment face 51a of binding agent 16 bonding each stacked steel plate unit 51 and the gap pad 63 stacked steel plate unit 51 that is adhesively fixed mutually, thereby core body 50 made as the magnetic circuit of this reactor.
As shown in Figure 9, binding agent 16 is filled between U-shaped stacked steel plate 61 and the gap pad 63 and between I shape stacked steel plate 62 and the gap pad 63.Guarantee that bonding mutually U-shaped stacked steel plate 61 and gap pad 63 and mutual bonding I shape stacked steel plate 62 and the distance between the gap pad 63 are d.This for example preferably is set at apart from d and is equal to or less than 1mm.
Like this, because when guaranteeing that distance between gap pad 63 and each stacked steel plate 61 and 62 is d, therefore binding agent 16 bonds to U-shaped stacked steel plate 61 and I shape stacked steel plate 62 on the gap pad 63, prevents that U-shaped stacked steel plate 61, I shape stacked steel plate 62 and gap pad 63 are subjected to displacement and alleviate the stress that acts on these parts.Therefore suppress vibration, thereby reduce noise.
Particularly, binding agent 16 can firmly bond to them on the gap pad 63 behind the impregnating varnish of removing on abutment face 61a and the 62a.Thereby prevent that U-shaped stacked steel plate 61, I shape stacked steel plate 62 and gap pad 63 are subjected to attraction and the magnetostrictive stress that is caused by magnetic flux change in the magnetic circuit, thereby prevent to vibrate or run foul of each other.Thereby reduce the noise of core body 50.
Also can prevent by thermal cycle and impact the degeneration cause, thereby prevent that noise from becoming big as time passes.
Because integrally molded with the binding part of U-shaped stacked steel plate 61, I shape stacked steel plate 62 and gap pad 63 resin bobbin 64 in each stacked steel plate unit 51, so U-shaped stacked steel plate 61, I shape stacked steel plate 62 and gap pad 63 reliability of fixation are improved.
