Description
Technical field
The invention provides a kind of motor stator fixture, particularly a kind of collocation design by flexible fastening thing and the intrinsic assembly of motor is in case the motor stator fixture that fastening comes off.
Background technology
If bond strength when motor is assembled causes stator to come off because of vibrating constantly not enough down in long-term operation easily.Therefore, need a kind of design that can significantly improve motor assembling intensity badly with easy means cheaply.
Summary of the invention
Therefore, purpose of the present invention is providing a kind of motor stator fixture, and it is by the collocation design of a flexible fastening thing and motor drive shaft bearing sleeve, and the stator fixed effect can obtain motor running the time, and significantly improves the assembling intensity of motor.
In order to achieve the above object, the invention provides a kind of motor stator fixture, it is characterized by and comprise:
One bearing holder (housing, cover), a pre-position on its surface offers a grooving, the upper limb tool equal height of the stator seat end face that this precalculated position is adjacent with this bearing holder (housing, cover); And
One flexible fastening thing, this flexible fastening thing of part embeds in this grooving and remainder pastes this stator seat end face upper limb.
The present invention also provides a kind of motor stator fixture, it is characterized by to comprise:
One bearing holder (housing, cover), a pre-position on its surface offers a grooving, and it coats the end face tool equal height of an insulation division of coil this precalculated position and a stator seat; And
One flexible fastening thing, this flexible fastening thing of part embeds in this grooving and remainder pastes this end face of this insulation division, and this grooving and this flexible fastening thing are in the form of a ring.
The present invention provides a kind of motor stator fixture again, it is characterized by to comprise:
One bearing holder (housing, cover), a pre-position on its surface offers a grooving, the end face tool equal height of the silicon steel sheet group of this precalculated position and a stator seat; And
One flexible fastening thing, this flexible fastening thing of part embeds in this grooving and remainder pastes this end face of this silicon steel sheet group, and this grooving and this flexible fastening thing are in the form of a ring.
The grooving that the present invention utilizes the bearing holder (housing, cover) surface to offer makes the inner margin portion of a flexible fastening thing be positioned at grooving, is exposed to the outer peripheral edge portion of grooving and then is covered on the stator seat end face.The grooving on bearing holder (housing, cover) surface offer the position, apical side height by the part of stator seat adjacent shafts bearing sleeve, that is decide, and provide suitable grooving working depth to make the subregion of flexible fastening thing can be covered on the stator seat end face by the upper limb height of a stator seat end face adjacent with bearing holder (housing, cover).
By this design, when causing stator seat, motor vibrations moves upward, when driving the flexible fastening beyond the region of objective existence edge be covered on the insulation division end face simultaneously and making progress, this moment flexible fastening thing inner edge and bearing holder (housing, cover) push against strength, can offset the upwards strength of stator seat, obviously reach the effect of fixing motor stator, significantly improve the assembling intensity of motor.

Embodiment
Please refer to Figure 1A, Figure 1A buckles 12 stereogram for showing a C type that applies to motor stator fixture of the present invention.Shown in Figure 1A, the C type is buckled 12 and is a kind of annular resilient thing of tool breach.When applying external force, C shape button 12 can expand outwardly the profile variation of generation shown in Figure 1B dotted line by indentation, there, then can borrow the elastic restoring force of itself to revert to original profile after external force removes.
Fig. 2 is according to one embodiment of the invention, show the generalized section of the motor 10 with stator fixing apparatus, and Fig. 3 is the partial enlarged drawing M of Fig. 2.As shown in Figure 2, motor 10 has a bearing holder (housing, cover) 14 and a stator seat 16.Stator seat 16 has an insulation division 16a who coats coil.
The partial enlarged drawing M of Fig. 3, clear demonstration C type of the present invention is buckled 12 and is applied to the stator fixed effect that motor 10 is produced.As shown in Figure 3, the present invention at first forms a grooving 14a in bearing holder (housing, cover) 14 surfaces, makes the C type buckle 12 and is embedded in the grooving 14a.This grooving 14a is opened on the bearing holder (housing, cover) 14 position with insulation division 16a end face tool equal height H, and grooving 14a is towards the working depth of bearing holder (housing, cover) 14 inside, is set to buckle 12 when the C type and can make its inner rim partly be positioned at grooving when embedding groovings and peripheral edge portion is exposed to outside the grooving.
Fig. 4 is according to another embodiment of the present invention, shows the generalized section of the motor 20 with stator fixing apparatus.As shown in Figure 4, motor 20 has a bearing holder (housing, cover) 24 and a stator seat 26.Stator seat 26 has the silicon steel sheet group 26a that a wound coil 28 forms.
According to present embodiment, the grooving of bearing holder (housing, cover) 24 is opened on the bearing holder (housing, cover) 24 position with silicon steel sheet group 26a end face tool equal height H ', and this grooving is towards the working depth at bearing holder (housing, cover) 24 centers, is set at equally to buckle 22 when the C type and can make its part be positioned at grooving when embedding groovings and remainder is exposed to outside the grooving.Therefore, the C type is buckled 22 and is exposed to the end face that the outer peripheral edge portion of grooving can be covered on silicon steel sheet group 26a, when the vibration of motor running causes stator seat 26 to move upward, the C type is buckled the upwards strength that strength can be offseted stator seat 26 integral body equally that pushes against of 22 inner margin portion and bearing holder (housing, cover) 24, reaches the effect of fixing motor stator.
By above-mentioned different embodiment as can be known, the present invention is applicable to multi-form motor fully, only need stator seat at different motors, the apical side height of the part of its adjacent shafts bearing sleeve is selected the bearing holder (housing, cover) grooving and is offered the position, in other words, only need to decide grooving to offer height by the upper limb of its end face adjacent of stator seat with bearing holder (housing, cover), and provide suitable grooving working depth to make the subregion of a flexible fastening thing can be covered on the stator seat end face, can obtain motor stator fixed effect of the present invention.
Moreover the grooving that the bearing holder (housing, cover) surface is offered does not limit its form can hold flexible fastening thing subregion to get final product, but preferable with the bigger circular profile of contact area.
Bearing holder (housing, cover) can be metal material and constitutes, for example a copper sheathing.Bearing holder (housing, cover) adopts as the plastic material formation of the class of engineering plastics also can.
C type of the present invention is buckled profile and is not limited, and can do different the variation according to operational mode, for example also can be the C type with the circular hole of easily seizing the application of force on both sides by the arms shown in Figure 5 and buckles 32.
Further it, the flexible fastening thing of connection shaft bearing sleeve of the present invention and stator seat is not defined as a C type and buckles, only need reach the subregion can enter the effect that grooving and subregion paste the stator seat end face and get final product, and can be any type of flexible fastening thing, promptly show the triangle ring-type fastener 34 that is different from C shape button profile as Fig. 6.The flexible fastening thing is preferable with ring-type so that the collocation bearing holder (housing, cover) profile and bigger contact area is arranged.
The above only is an illustrative, but not is restricted person.Anyly do not break away from spirit of the present invention and category, and, all should be contained in the claim of the present invention, but not be defined in the above embodiments its equivalent modifications of carrying out or change.
