Fig. 6 is the perspective view of an example of motor erector, and Fig. 7 is the motor erector shown in Fig. 6, the perspective view of being seen from the bottom direction;
Shown in Fig. 6 and 7, motor erector 300 basically forms annular, and planar portions 313 forms on motor erector 300.Preferred planar portion 313 basically forms annular, go up perpendicular to axle 4 because limit portion 131 is attached to the base portion 2a of cylinder 2, and therefore stator 6 firmly is arranged on the cylinder 2.
In addition, motor erector 300 comprises other coupling aperture 310, and stator 6 is attached to the base portion 2a of cylinder 2 by bolt or other like of passing coupling aperture 310.Surpass three coupling apertures 310 along forming on the circumferencial direction of motor erector 300 herein.
When stator 6 was attached to cylinder 2, described location indentations 314 can guarantee the concentricity of stator 6 and can prevent stator 6 off-centre.Therefore, can reach the effect that reduces motor noise by location indentations 314.
Herein, in order firmly to support stator 6, motor erector 300 can be made by metal (preferred steel plate).
As shown in Fig. 5 to 7, side surface 312 and 311 can form on inside and outside with respect to the radial direction of planar portions 313. Side surface 312 and 311 embeds the base portion 2a of cylinder 2, to strengthen the adhesion between motor erector 300 and the cylinder 2.Therefore, also can strengthen adhesion between stator 6 and the cylinder 2.
Can promote the adhesion between described motor erector 300 and the cylinder 2 by the base portion on the outer surface that is formed at base portion 2a, and motor erector 300 is arranged on the base portion.The section configuration of the base portion preferably section configuration with motor erector 300 is corresponding.The coupling aperture 320 of motor erector or the coupling aperture 310 of stator 6 preferably form in base portion.
Fig. 8 and 9 is the sectional view of another example of motor erector 300, shows the AA section of another example shown in Fig. 6 especially.On motor erector 300, along the circumferential direction do not form ribs shown in Fig. 6.On the motor erector, form ribs shown in Fig. 8 and 9.As shown in Fig. 8 and 9, side surface 312 and 311 can not form on motor erector 300.
Described ribs 316 extends and diametrically perpendicular to planar portions 313.Ribs 316 embeds the base portion 2a that is attached to cylinder, so that strengthen the adhesion between cylinder and the motor erector.Corresponding with described ribs, the outward appearance that is arranged on the base portion on the cylinder can be multiple.
When rotor rotated, because ribs 316 extends diametrically, stator can well bear repulsion in a circumferential direction.Herein, ribs 316 can form by lancing technology.On planar portions 313, form and ribs 316 corresponding lancing holes 312.
Fig. 6 and 9 is depicted as integrated motor erector, and the motor erector is not restricted to this.Especially, although do not show in the accompanying drawings,, correspond respectively to the joint portion of stator can a plurality of motor erectors are set.Preferably the motor erector interconnects.
In addition, projection (boss) 2c forms in the part of motor erector combination, increases the intensity of described part.Therefore, can be by the adhesion between described protruding 2c enhancing cylinder and the motor erector.Coupling aperture forms on protruding 2c, and motor erector or stator are attached on the cylinder by described coupling aperture.Therefore, protruding 2c can be used to increase the intensity of described coupling aperture.Although do not show in the accompanying drawings,, can form a plurality of ribs near protruding 2c in order to increase the intensity of protruding 2c.At this moment, protruding 2c and ribs can be one-body molded with cylinder 2.
With next in conjunction with different by bolt T between above-mentioned cylinder and the motor erector 300, for one-body molded with cylinder 2, the motor erector can embed moulding at the base portion 2a of cylinder.In this case, can dispense aborning in conjunction with the step of motor erector 300 to the cylinder 2.
Motor erector shown in Fig. 6 to 9 can be applicable to described motor erector.Can not need to be used for described motor erector is attached to coupling aperture 320 on the cylinder.When cylinder formed, resin can permeate by described coupling aperture, was feasible with the adhesion that strengthens between motor erector and the cylinder.
In addition, the adhesion between motor erector and the cylinder can be passed through above-mentioned side surface 311 and 312, and lancing hole 315 and ribs 316 and strengthen.
Preferably, coupling aperture 310 can be exposed to the outer surface of cylinder, is attached on the cylinder by the motor erector to make things convenient for stator.For this reason, only be that the predetermined portions of motor erector can insert die casting in cylinder.Especially, as shown in Figure 5, the predetermined portions of the planar portions 313 that forms on motor erector 300 extends to the outer surface of cylinder.Therefore, coupling aperture 310 may extend into the outer surface of cylinder.The position determines that the outer surface that recess 314 extends to cylinder 2 also is fine.In this case, do not need to be used in conjunction with the bolt of motor erector to the cylinder.
Selectable, because planar portions 313 can embed moulding fully, only coupling aperture 310 can be exposed to the outer surface of cylinder.That is, coupling aperture 310 from planar portions 313 to the upper process preset distance, and therefore only coupling aperture 310 may extend into the outer surface of cylinder.For this reason, at first form the little coupling aperture of radius have than anticipation, and the anchor clamps with anticipation radius are pressed into pass described coupling aperture in the coupling aperture 310.Therefore, formed from the coupling aperture of planar portions to the upper process preset distance.
Here, because the major part of motor erector 300 embeds moulding in cylinder, can strengthen the adhesion between motor erector and the cylinder.
As mentioned above, consider the simplification of cylinder manufacturing step, when motor erector 300 embeds moulding so that with described cylinder when one-body molded in cylinder, the predetermined portions of preferred motor erector is exposed to the outer surface of cylinder.This is that it is difficult then making cylinder body because if the integral body of motor erector all embeds moulding in cylinder form.Especially, the above-mentioned part of exposing is by the metal mold support, and therefore in the time of the manufacturing cylinder, described motor erector is easy to embed moulding in cylinder.
Figure 10 is under motor erector 300 most of states for the insertion die casting, the predetermined portions front view of cylinder base portion 2a.
That is, only motor erector 300 outer coupling apertures 310 are exposed to the outer surface of cylinder, and motor erector 300 outer other parts are arranged in the cylinder.So, when making cylinder, motor erector and cylinder are one-body molded.With the concentricity that minimizes between motor erector and the cylinder.Therefore, can prevent that concentricity subsequently from changing.
Because above-mentioned motor erector can save jar support essential in existing roller washing machine, and boost productivity the man-hour of minimizing production line.And, because saved jar support, reduced the gross weight of roller washing machine.
On the other hand, the stator 6 that is provided with on the motor shown in Figure 11 and 12, comprises helical core (spiral core) SC, insulator 144, coil 142 and connecting portion 143.Insulator 144 is around helical core SC.Coil 142 is wrapped on each tooth 151 of helical core SC.Connecting portion 143 is one-body molded with insulator 144, and at three positions that surpass of insulator 144, described connecting portion protrudes to inside.The weight of stator 6 surpasses 1.5kg, because trend is to be used for big capacity roller washing machine.Yet according to the present invention, stator 6 adapts with helical core SC, and stator is attached on the cylinder base portion 2a by insulator 144, and this makes described stator with identical motor performance dwindle.
Helical core SC has sandwich construction, and steel disk clump bottom is used for kinking to the rotation of top layer spiral therein.Tooth 151 outwards protrudes diametrically from the base portion of helical core SC, and embeds the base portion formation of groove 152 at helical core SC, so that the stress that reduces to produce when coiling on described iron core.
Helical core SC comes combination by passing the rivet that is formed on the hole on the described base portion 150.The initial part of helical core winding (winding) and the rearward end of helical core winding are in the predetermined portions welding of base portion 150, and described predetermined portions contacts with described initial part and described rearward end.
The embedding groove 152 that forms on the base portion 150 of described helical core SC can form with rectangle or trapezoidal shape, or can form with arcuate shape.
With reference to attached Figure 13 and 14, surpass in the insulator 144 three joint portions 143 from the circumferential surface of described iron core to projecting inward, described joint portion 143 is one-body molded with insulator 144, the length of each tooth 151 that protrudes from the outer surface of described helical core SC is with " a " expression, and represents with " b " to the distance at the 143 coupling aperture 143a centers that form in the joint portion from the surface, inside of described helical core SC.Described joint portion 143 forms with the regulation of a 〉=b.
At this moment, joint portion 143 forms with 20% the height that surpasses described height overall unshakable in one's determination.The height of preferred described joint portion 143 is whole height unshakable in one's determination.
At least one cavity 143c is arranged on the joint portion 143, so that the vibrations of buffering motor.Locator protrusions 143b is arranged on the joint portion 143.Herein, describedly decide projection 143b and be embedded into and decide in the recess 314, and it extends in the rear wall of cylinder 2 with the form that embeds moulding.
In addition, spring catch 143p or metal tube are inserted among the coupling aperture 143a, so that strengthen the intensity of coupling aperture 143a.
Below, description is arranged on the operation process of the actuator in the roller washing machine with said structure.
For the motor of drive installation on board rotates described stator 6, the electric current of the control by the controller (not shown) flows in the coil 142 of stator 6.Therefore, axle 4 rotations that are connected with connector 16 dentations that are connected to rotor 5, and driving force is transferred to cylinder 3 by axle 4 and comes swing roller 3.
On the other hand, will the structure applications of actuator be described in the effect of roller washing machine.
At first, make by plastic material according to the cylinder 2 of roller washing machine of the present invention with good heat-insulating property.Therefore, described roller washing machine is lighter.Cylinder is embedded into moulding.Therefore, productivity ratio improves.
In addition, as bearing support assemblies, make by aluminium alloy according to the bearing housing 7 of roller washing machine of the present invention.As a result, bearing housing 7 does not have thermomechanical effect under high relatively temperature, and can be applied to have the roller washing machine of dry cycle.
When cylinder 2 is embedded into moulding, embed moulding in the hub of metal bearing case 7 on the rear wall that is arranged at cylinder 2, so that one-body molded with cylinder 2.Can omit the step that bearing housing 7 is assembled on cylinder 2 rear walls.Therefore, installation step can be oversimplified and therefore save man-hour.
In addition, as shown in figure 11, stator on the motor and rotor 5 comprise the embedding groove 152 on the base portion 150 that is formed at helical core SC, the stress when reducing unshakable in one's determination the coiling.Therefore, described coiling can be carried out with lower power.
Especially, as shown in figure 13, stator 6 comprises and surpasses three Cong Suoshu joint portion 143 unshakable in one's determination, and its inner circular side face from iron core is protruding to inside in the radial direction.The length of each tooth 151 that protrudes from the outer surface of helical core SC is with Reference numeral " a " expression, and from the surface, inside of described helical core SC to the distance at described coupling aperture 143a center with " b " expression, it may be prescribed as a 〉=b.
That is, because the part of load is more approached to activate in the position of coupling aperture 143a, starting torque is less, and this is favourable.Yet if too close this part in the position of coupling aperture 143a, the diameter of screw should be littler.As a result, use too many screw to come support stator 6.Consider these, determined the regulation of above-mentioned a 〉=b.
