Description
Technical field
The utility model relates to machine field, particularly relates to a kind of rotor and adopts the motor of this rotor.
Background technology
Motor is used to realize the device that electric energy and mechanical energy and mechanical energy and electric energy are changed, and is usually made up of rotor and stator two parts.Wherein, rotor comprises armature spindle and some armature punchings, and armature punching is provided with centre bore, and some armature punchings are sheathed and be fixed on described armature spindle as iron core by centre bore.As shown in Figure 1, a kind of known fixed armature lamination to the mode of armature spindle is, the outer wall of armature spindle 1 arranges some juts 2, make to form interference fit between the inwall of the centre bore of the outer wall of armature spindle 1 and some armature punchings 3, thus these armature punchings 3 are fixed on armature spindle 1.Another kind of known fixed armature lamination to the mode of armature spindle is, some armature punchings are set in after on described armature spindle by centre bore, by a particular tool, extruding is carried out to the subregion of armature spindle and produce groove, the groove utilizing these deformation to produce carries out spacing to armature punching, thus is fixed on armature spindle by some armature punchings.No matter adopt which kind of method above-mentioned, known fixed armature lamination all needs more complicated technique and higher cost to the mode of armature spindle.
Utility model content
The purpose of this utility model is, provides a kind of rotor, and this motor rotor construction is simple, with low cost, is easy to realize.
Another object of the present utility model is, provides a kind of motor, and this motor adopts the simple rotor of structure, reduces cost and is easy to assembling.
For achieving the above object, the utility model provides a kind of rotor, comprise armature spindle and some armature punchings, each described armature punching arranges centre bore, the diameter of described centre bore is greater than the external diameter of described armature spindle, described armature punching is sheathed on successively on described armature spindle by described centre bore and forms armature punching group, fill an adhesion coating between the inwall of the centre bore of described armature punching group and the outer wall of described armature spindle, make in axis and radial direction, all relative displacement not to occur between described armature punching group and described armature spindle.
Alternatively, described adhesion coating is the adhesion coating of insulation.
Alternatively, the adhesion coating of described insulation is that particle or powder insulation material cooling curing after melting are formed.
Alternatively, outer surface one insulating coating of the armature punching at the two ends of described armature punching group is positioned at.
Alternatively, the adhesion coating between the inwall of the centre bore of described armature punching group and the outer wall of described armature spindle forms with the insulating coating of outer surface of armature punching at the two ends being positioned at described armature punching group.
The utility model provides a kind of motor simultaneously, adopts aforesaid rotor.
Rotor of the present utility model and motor eliminate the some juts arranged on armature spindle outer surface, do not need on armature spindle, to squeeze out groove by extra instrument yet, thus simplify the shape of armature spindle outer surface, save the manufacturing cost of rotor, simplify the technique of assembling armature punching simultaneously.
In order to further understand feature of the present utility model and technology contents, refer to following about detailed description of the present utility model and accompanying drawing, but accompanying drawing only provide reference and explanation use, is not used for being limited the utility model.
Accompanying drawing explanation
Aforementioned and the other side of the application is more completely understood by detailed introduction done with reference to the accompanying drawings and is understood, in the accompanying drawings:
Fig. 1 is the assembly structure schematic diagram of prior art rotor axle and armature punching group.
Fig. 2 is the assembly structure schematic diagram of the utility model rotor axle and armature punching group.
Embodiment
For helping those skilled in the art to understand the claimed theme of the utility model definitely, describe embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Be rotor 100 see Fig. 2, in order to clearly embody structure of the present utility model, the other parts irrelevant with the utility model comprised in rotor 100 are omitted in picture and text.As shown in Figure 2, rotor 100 comprises armature spindle 10 and some armature punchings 20, and each armature punching 20 is provided with centre bore 21, and the diameter of centre bore 21 is greater than the external diameter of armature spindle 10.Each armature punching 20 is sheathed on armature spindle 10 by centre bore 21 successively, forms armature punching group 22.Diameter due to centre bore 21 is greater than the external diameter of armature spindle 10, therefore there is gap between the inwall of the centre bore 21 of armature punching group 22 and the outer wall of armature spindle 10.In order to fixed armature stack of laminations 22, between the inwall of the centre bore 21 of armature punching group 22 and the outer wall of armature spindle 10, be filled with adhesion coating 30, make no matter in axis or radial direction, all relative displacement can not occur between armature punching group 22 and armature spindle 10.
In this embodiment, the mode of filling adhesion coating 30 is, insulating material is thrown in the gap between the inwall and the outer wall of armature spindle 10 of the centre bore 21 of armature punching group 22, this insulating material at normal temperatures initial condition is particle or Powdered, after heating, particle or powder smelting are for having adhesive liquid material, these have adhesive liquid material and can flow between the gap between the inwall of the centre bore 21 of armature punching group 22 and the outer wall of armature spindle 10 and fill gap, these can solidify after having the cooling of adhesive liquid insulating material, thus make relative displacement to occur between armature punching group 22 and armature spindle 10.
In this embodiment, the outer surface being positioned at the armature punching 20 at the two ends of armature punching group 22 has insulating coating 23, and insulating coating 23 adopts the insulating material same with adhesion coating 30.After insulating material cooling curing, the adhesion coating 30 between the inwall of the insulating coating 23 of the outer surface of the armature punching 20 at the two ends of armature punching group 22 and the centre bore 21 of armature punching group 22 and the outer wall of armature spindle 10 forms.
It will be understood by those skilled in the art that, adhesion coating 30 and insulating coating 23 can adopt different insulating material, similarly, adhesion coating 30 and insulating coating 23 may not be and form, as long as adhesion coating 30 can play effect armature punching group 22 be fixed on armature spindle 10.
As previously mentioned, rotor of the present utility model and adopt the electric machine structure of this rotor simple, eliminates the operation increasing ledge or squeeze out groove on armature spindle; After utilizing insulating material to heat, armature punching group and armature spindle are fixed by the characteristic of adhesion, provide cost savings, and are easy to realize.
Although show based on specific execution mode and describe the application, the application is not restricted to shown details.On the contrary, in claim and equivalent scope of replacing thereof, the various details of the application can be transformed.
