It includes a wire-winded plate with winded coil, several stator iron cores which are laminated and inserted on the wire-winded plate for forming magnetic field and isolating layer sandwiched between the wire-winded plate and stator iron core contacted with the wire-winded plate. When the motor is started, said isolating layer can prevent the stator iron core from producing vibration, so that it can prevent motor from producing vibration noise or wearing.
Description
Technical field
The present invention relates to a kind of vibration noise prevention device of reciprocable machine, particularly relate to a kind of at the vibration noise prevention device of the separator that presss from both sides soft material between stator core and the wire-wrap board with the reciprocable machine of minimizing core vibration.
Background technology
Common reciprocable machine is that the electromagnetic field with the mouth shape becomes the tabular magnetic field that each bar magnetic line of force is parallel to each other, and flat mover is arranged on the upside of stator, makes its variation along with magnetic field do rectilinear motion back and forth.
A kind of outer stator and inside stator that stator is divided into cylinder type appearred recently, and between outer stator and inside stator, be provided with mobilizable mover, and the side in outer stator and the inside stator is provided with the spiral coil, and on the mover device of correspondence, stick magnetic stripe, make mover be subjected to the magnetic line of force effect of spiral coil and the reciprocable machine that axially moving reciprocatingly.
Fig. 1 is traditional reciprocable machine fragmentary cross-sectional view.Fig. 2 is the stereogram of assembling outer stator process in traditional reciprocable machine.
As shown in Figure 1, traditional reciprocable machine is formed by the stator 10 that produces the magnetic line of force with along the mover 20 that the magnetic line of force of stator 10 moves reciprocatingly.As shown in Figure 2, stator 10 intersects the wire-wrap board B upper strata that is inserted into annular by the thin stator core 11a with " " shape and " " shape and stacks and long-pendingly forms the outer stator 11 of cylinder type and be made up of the cylinder type inside stator 12 that a plurality of thin stator core 12a accumulations form.After outer stator 11 and inside stator 12 will separately stator core 11a, 12a be laminated to wire-wrap board B and not shown fixture, respectively be pressed into retainer ring 11b, 12b in two sides in order to keep the cylindrical shape formed by each laminated iron core.Mover 20 by be arranged between outer stator 11 and the inside stator 12 and mobilizable mover fuselage 21 with for corresponding with the spiral coil C on the stator 10 and form by the magnetic stripe 22 that is set in qually spaced in mover fuselage 21 outsides.After the energising of the spiral coil C on the stator 11, around spiral coil C, form the magnetic line of force.The magnetic line of force flow into the opposite side of outer stator 11 once more after along outer stator 11 1 effluents to inside stator 12 and forms closed loop.At this moment, be in the magnetic stripe 22 of the mover 20 in the magnetic line of force that spiral coil C produces and the magnetic field interaction of spiral coil C, move around along the magnetic line of force direction of spiral coil C, thereby make the fuselage 21 of mover 20 also do straight reciprocating motion.But, in this traditional reciprocable machine outer stator, though use and a plurality of stator core 11a are intersected the lateral surface that inserts wire-wrap board B make it the method that columnar structured two sides stacked and after stacked are pressed into retainer ring 11b stator structure is remained unchanged, but as shown in Figure 3, can cause the slit occurring between stator core and the wire-wrap board B in fabrication and processing error that occurs between each stator core 11a and the wire-wrap board B or stacked assembly error, stator core 11a is vibrated with compressor, thereby cause the wearing and tearing of vibrating noise or supportive device.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of vibration noise prevention device that reduces the stator core and the reciprocable machine of the vibrating noise of its supportive device generation.
In order to achieve the above object, the vibration noise prevention device of reciprocable machine provided by the invention comprise the wire-wrap board that twines the spiral coil, be inserted on the wire-wrap board for form the stacked a plurality of stator cores in magnetic field and be clipped in wire-wrap board and stator core between separator.
The vibration noise prevention device of reciprocable machine of the present invention is to add separator between wire-wrap board and stator core, stator core is close on the wire-wrap board, the vibration of each stator core can be when electric motor starting, prevented, and the wearing and tearing of the vibrating noise or the wire-wrap board of motor can be prevented.

Embodiment
As Fig. 4, shown in Figure 5, reciprocable machine outer stator of the present invention is made up of with retainer ring 130 that keeps the stator core cylindrical shape and the separator 140 that closely is clipped between wire-wrap board 110 and the stator core 120 wire-wrap board 110 that twines the spiral coil C can accept foreign current, a plurality of stator cores 120 that are layered in wire-wrap board 110 lateral surfaces, the both sides that are pressed into stator core 120.Wire-wrap board 110 adopts resin materials to make, and it is inner, and to form section be the coil mounting groove 111 of " V " font, and the centre position of wire-wrap board 110 sides protrusion has formed the portion of terminal 112 that links to each other with spiral coil C and join with external power source.When the stator core 120 with " " shape and " " shape structure after cross layered formation on the wire-wrap board 110 is columnar structured, retainer ring 130 is pressed in the holddown groove 121.Retainer ring 130 is annular, and its width is bigger slightly than holddown groove 121 width, preferably makes retainer ring 130 or holddown groove 121 distortion when being pressed into and makes structure more fastening.In addition, separator 140 adopts resin material to make, and it is annular or the circular arc with specific thickness and width, and wire-wrap board 110 is closely contacted with separator 140 with stator core 120.After twining an amount of spiral coil C on the coil mounting groove 111 at wire-wrap board 110, the lid of not shown wire-wrap board 110 is covered sealing.Intersection is inserted the stator core 120 of " " shape and " " shape and is laminated into cylindrical shape on the lateral surface of wire-wrap board 110 then.For prevent wire-wrap board 110 sides and and its tangent stator core 120 between the slit appears, preferably earlier the separator 140 of resin material is close to the side and then the stacked stator core 120 of wire-wrap board 110.Be pressed at last retainer ring 130 on the holddown groove 121 that is provided with in the cylindrical shape two sides that each stator core 120 forms keeping its shape invariance, thereby just can finish the assembling of stator for reciprocating motor.With the spiral coil of the reciprocable machine of the present invention assembled is logical go up electric current after, it produces the magnetic line of force along outer stator and inside stator, mover is then done straight reciprocating motion back and forth along magnetic line of force direction.If at this moment iron core is not close on the wire-wrap board but when forming certain slit, iron core can vibrate and contacts with wire-wrap board because of the effect that is subjected to magnetic force produces, thereby causes problems such as noise and wearing and tearing.And the present invention has added separator at the medial surface of wire-wrap board and stator core, and it can make wire-wrap board and stator core in conjunction with tight, and can prevent the vibration of each stator core, thereby can prevent the wearing and tearing of the vibrating noise or the wire-wrap board of reciprocable machine.
