Abstract
The utility model discloses the rotor sheet that a kind of coil inlay card is stable, its drip irrigation device is, comprise rotor sheet body, rotor sheet is provided with the winding slot circumferentially distributed, winding slot is provided with for being communicated with extraneous opening, winding slot inwall is provided with the elastic layer be made up of rubber, and for be detachably fixedly connected with between elastic layer with winding slot, the thickness of elastic layer is thinning gradually along the direction away from rotor sheet body central; Elastic layer has relative elasticity, makes the extruding being subject to elastic layer when coiling sticks in winding slot again, and whole elastic layer can keep stable by extruding.
Description
Technical field
The utility model relates to a kind of rotor, and more particularly, it relates to the stable rotor sheet of a kind of coil inlay card.
Background technology
Rotor is motor center rotatable parts, and the coil after energising on stator and the mutual magneticaction of epitrochanterian coil, can allow rotor high-speed rotate, produce enough power, drives working group's motion.Stator punching is after being stacked into stator, and copper cash is around on winding slot.Run at motor start, anxious the factor effect such as to stop under, copper cash is by the impact of electromagnetic force, thermal effect and mechanical stress, the vibration occurred under serious short-circuit conditions in addition and impact, distortion and displacement may be there is in copper cash at winding slot, therefore winding is wanted to be fixed in winding slot reliable, copper cash and winding slot must be made to have good Mechanical Contact, play anti-loosing effect.Traditional locking measure is wound around low-resistance irony asbestos yarn at copper cash outer surface, but anti-loosing effect is still not ideal enough.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of utilization in winding slot, to be provided with elastic layer by rotor sheet stable for coil inlay card.
For achieving the above object, the utility model provides following technical scheme: the rotor sheet that a kind of coil inlay card is stable, comprise rotor sheet body, described rotor sheet is provided with the winding slot circumferentially distributed, described winding slot is provided with for being communicated with extraneous opening, it is characterized in that: described winding slot inwall is provided with the elastic layer be made up of rubber, for to be detachably fixedly connected with between described elastic layer with described winding slot, the thickness of described elastic layer is thinning gradually along the direction away from rotor sheet body central.
By adopting technique scheme, the inner elastic layer of winding slot of rotor sheet, elastic layer has relative elasticity, makes the extruding being subject to elastic layer when coiling sticks in winding slot again, and whole elastic layer can keep stable by extruding.And the thickness of elastic layer is increased by interior foundry goods outward, elastic layer thickness the closer to outside is larger, just illustrates elasticity larger, the extruding inside coil can tried one's best, ensure that the stable of the installation of coil, prevent from loosening because centrifugal, the vibrations in rotating etc. produce.The unique elasticity of rubber and insulating properties, had rubber layer, can avoid being immersed by rotor or brushing this procedure of insulating varnish.
The utility model is set to further: described winding slot inwall is also provided with draw-in groove, and described elastic layer is provided with the projection plugged together with described draw-in groove near the side of winding slot.
By adopting technique scheme, the inlay card of projection and draw-in groove, elastic layer can be allowed to be fixed on above rotor can not come off, but comparatively fast aging due to rubber, review and needing with changing directly just can peeling away of elastic layer, and directly stick just passable when inlay card, very there is practical value, while ensureing installation strength, facilitate installation process.
The utility model is set to further: described draw-in groove is swallow-tail form.
By adopting technique scheme, the draw-in groove of swallow-tail form, is compared to other shape, can by projection firmly inlay card inside draw-in groove, as long as projection is once be snapped in draw-in groove, in the normal process used, would not situations such as coming off be there is.
The utility model is set to further: described elastic layer is provided with anti-skidding lines away from the side of described winding slot.
By adopting technique scheme, anti-skidding lines can increase the frictional force of elastic layer for coil, reduces the displacement of coil after installation in rotor, ensures that it can be stablized and be effectively fixed.

Embodiment
Referring to figs. 1 through Fig. 3, the rotor sheet embodiment that the utility model inlay card is stable is described further.
The rotor sheet that a kind of coil inlay card is stable, comprise rotor sheet body 1, rotor sheet body 1 is circular, middle driving has the circular hole passed for rotating shaft, and rotor sheet is provided with the winding slot 11 circumferentially distributed, and is distributed on the outward flange of rotor sheet body 1, rotor is the little shape of one end Da I Member, large one end outwardly, little one end inwardly, specifically as shown in Figure 2.Larger one of rotor offers an opening, and the connection rotor of opening is with extraneous.
Winding slot 11 inwall is provided with the elastic layer 2 be made up of rubber, and the thickness of elastic layer 2 is thinning gradually along the direction away from rotor sheet body 1 center.The inner elastic layer 2 of winding slot 11 of sub-pieces, elastic layer 2 has relative elasticity, makes the extruding being subject to elastic layer 2 when coiling sticks in winding slot 11 again, and whole elastic layer 2 can keep stable by extruding.And the thickness of elastic layer 2 is increased by interior foundry goods outward, elastic layer 2 thickness the closer to outside is larger, just illustrates elasticity larger, the extruding inside coil can tried one's best, ensure that the stable of the installation of coil, prevent from loosening because centrifugal, the vibrations in rotating etc. produce.The unique elasticity of rubber and insulating properties, had rubber layer, can avoid being immersed by rotor or brushing this procedure of insulating varnish.
Winding slot 11 inwall is also provided with draw-in groove 111, and elastic layer 2 is provided with the projection 21 plugged together with draw-in groove 111 near the side of winding slot 11, and draw-in groove 111 is swallow-tail form.The inlay card of projection 21 and draw-in groove 111, elastic layer 2 can be allowed to be fixed on above rotor can not come off, but comparatively fast aging due to rubber, review and need with changing directly just can peeling away of elastic layer 2, and directly stick just passable when inlay card, very there is practical value, ensure while installation strength, facilitate installation process.The draw-in groove 111 of swallow-tail form, is compared to other shape, can by projection 21 firmly inlay card inside draw-in groove 111, as long as projection 21 is once be snapped in draw-in groove 111, in the normal process used, would not situations such as coming off be there is.
Elastic layer 2 internal layer is provided with anti-skidding lines 22.Anti-skidding lines 22 can increase the frictional force of elastic layer 2 for coil, reduces the displacement of coil after installation in rotor, ensures that it can be stablized and be effectively fixed.
