Description
Technical field
The utility model relates to a kind of rotor.
Background technology
Rotor is a vitals indispensable in motor, rotor is superimposed primarily of multiple rotor punching, armature spindle runs through the rotor punching of superposition again, and rotor punching is provided with installation through hole, installation through hole after superposition on rotor punching is interconnected, magnetic stripe on people are fixing on installation through hole, due to can heat be produced when rotor operationally can produce the running of high speed, some manufacturer can fill flabellum on armature spindle, thus the flowing of generation air is dispelled the heat to rotor, but because rotor is stacked up by multiple rotor punching, certain gap certainly will be there is between rotor punching, cause heat-conducting effect each other poor, cause the rotor punching temperature away from flabellum side still higher, and play a heat and be delivered to and magnetic stripe cause magnetic stripe heat expansion thus causes fracture.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of and is convenient to ventilate and carries out the rotor of efficiently radiates heat.
For achieving the above object, the utility model provides following technical scheme: a kind of rotor, comprise armature spindle, several rotor punchings, described armature spindle runs through rotor punching center, and described some rotor punchings are overlapped, and on described rotor punching, Circle-Array is shown several and installed through hole, magnetic stripe is provided with in described installation through hole, described rotor punching is provided with ventilation through hole, and described rotor punching side is provided with connecting groove, and described ventilation through hole is communicated with installation through hole by connecting groove.
Preferably, described ventilation through hole number is identical with installation through hole number, described ventilation through hole circumferentially array distribution.
Preferably, the degree of depth of described connecting groove is 0.5 times of rotor punching thickness.
Preferably, described ventilation through hole and armature spindle distance are less than and install through hole and armature spindle distance.
Compared with prior art, the beneficial effects of the utility model are: at rotor in the running, rotor punching producing heat is delivered on magnetic stripe, the ventilation through hole on multiple rotor punching is made to form a passage for air flowing because multiple rotor punching is superimposed, and due to ventilation through hole by connecting groove with install through hole communicate, thus when ambient atmos flows in ventilation through hole, thus the heat taken away on rotor punching, and heat on magnetic stripe is also by the air that is radiated in connecting groove, owing to ventilation through hole having certain air flowing, cause producing negative pressure in ventilation through hole, thus the air in connecting groove is extracted, thus easily magnetic stripe is dispelled the heat, effectively prevent magnetic stripe overheated and produce expansion, and be superimposed due to multiple rotor punching, thus certain gap will certainly be left between rotor punching, and between magnetic stripe and installation through hole, also there is this certain gap, and between gap, have some hotter gases, and after flowing into the air generation negative pressure in ventilation through hole and connecting groove is bled, be pumped again in gas make-up hotter between these gaps to connecting groove, thus heat radiation is produced to whole rotor, and the comparatively cold air in the external world also can fill between gap, heat radiation is produced to whole rotor, effectively ensure that rotor operationally can effectively dispel the heat, improve the useful life of rotor.

Embodiment
Referring to figs. 1 through Fig. 3, the utility model rotor embodiment is described further.
A kind of rotor, comprise armature spindle 6, several rotor punchings 1, described armature spindle 6 runs through rotor punching 1 center, described some rotor punchings 1 are overlapped, on described rotor punching 1, Circle-Array is shown several and is installed through hole 2, magnetic stripe 3 is provided with in described installation through hole 2, described rotor punching 1 is provided with ventilation through hole 4, described rotor punching 1 side is provided with connecting groove 5, described ventilation through hole 4 is communicated with installation through hole 2 by connecting groove 5, at rotor in the running, rotor punching 1 producing heat is delivered on magnetic stripe 3, the ventilation through hole 4 on multiple rotor punching 1 is made to form a passage for air flowing because multiple rotor punching 1 is superimposed, and due to ventilation through hole 4 by connecting groove 5 with install through hole 2 communicate, thus when ambient atmos flows in ventilation through hole 4, thus the heat taken away on rotor punching 1, and heat on magnetic stripe 3 is also by the air that is radiated in connecting groove 5, owing to ventilation through hole 4 having certain air flowing, cause producing negative pressure in ventilation through hole 4, thus the air in connecting groove 5 is extracted, thus easily magnetic stripe 3 is dispelled the heat, effectively prevent magnetic stripe 3 overheated and produce expansion, and be superimposed due to multiple rotor punching 1, thus certain gap will certainly be left between rotor punching 1, and also there is this certain gap between magnetic stripe 3 and installation through hole 2, and between gap, have some hotter gases, and after flowing into the air generation negative pressure in ventilation through hole 4 and connecting groove 5 is bled, gas make-up hotter between these gaps is pumped in connecting groove 5 again, thus heat radiation is produced to whole rotor, and the comparatively cold air in the external world also can fill between gap, heat radiation is produced to whole rotor, effectively ensure that rotor operationally can effectively dispel the heat, improve the useful life of rotor.
Ventilation through hole 4 number is identical with installation through hole 2 number, described ventilation through hole 4 circumferentially array distribution, make each installation through hole 2 all corresponding ventilation through holes 4 of energy, each magnetic stripe 3 is made all to have a runner that specifically ventilation through hole 4 is formed to carry out supplied gas flowing, be convenient to the heat radiation of magnetic stripe 3, and magnetic stripe 3 is dispelled the heat evenly, and because ventilation through hole 4 circumference array distributes, the amount even circumferential of excision is distributed, effectively prevent rotor from producing vibration when rotating because distribution of weight is uneven.
The degree of depth of connecting groove 5 is 0.5 times of rotor punching 1 thickness, and the temperature of rotor punching 1 is delivered to connecting groove 5 surface, in the air that heat can be effectively dispersed in connecting groove 5, improves the effect of heat radiation.
Ventilation through hole 4 is less than with armature spindle 6 distance installs through hole 2 and armature spindle 6 distance, due to rotor when rotated, magnetic stripe 3 will certainly produce centrifugal force, install on through hole 2 because magnetic stripe 3 is arranged on, when producing outside centrifugal force, magnetic stripe 3 can be resisted against completely and install through hole 2 inwall and prevent from most connecting groove 5 from producing pressure preventing distortion.
