Just the patent document " brush motor punching rotor " that the patent No. is 201420007499.4 is proposed for this this enterprise of problem, this patent document provides a kind of brush motor punching rotor, propose and offer louvre and radiating groove in punching, this technical scheme to some extent solves the heat dissipation problem of rotor core, but in the long practice of this enterprise, find again the place of this technical scheme or Shortcomings, because only just offer louvre in rotor core in this technical scheme, therefore the heat also just just left on rotor is intimate, and in the course of work of reality, the coupling part of rotating shaft and rotor core and rotating shaft also can produce very large heat, and in this technical scheme and the unresolved corresponding heat falling to produce in rotating shaft, and this partial heat can be delivered in rotor core by heat trnasfer, thus still can affect the integral heat sink problem of motor to a certain extent.Therefore should for this motor stamping rotor Problems existing, this enterprise, through long Researching and practicing, has carried out corresponding improvement to it again, makes this rotor obtain better radiating effect.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is the rotor providing a kind of energy efficiently radiates heat.
For achieving the above object, the utility model provides following technical scheme: a kind of rotor, comprise rotor body, rotor body comprises rotating shaft and rotor core, and rotor core comprises some rotor sheets be superimposed with each other, and rotor core is provided with shaft hole, rotating shaft is located in shaft hole, rotor core offers some first louvres, rotating shaft offers the second louvre, the first louvre be all conducted corresponding with the second louvre is arranged.
By adopting technique scheme, rotor core offers the first louvre, rotating shaft offers the second louvre, and the first louvre and the second louvre mutual conduction, therefore when this rotor body rotates heat production, rotating shaft and rotor core produce heat to be delivered in air-flow, simultaneously because the mutual conduction of the first louvre and the second louvre is arranged, with the quick circulation character utilizing air-flow when rotor body rotates, thermal current can under the circulation effect of air-flow, circulate away from rotating shaft and rotor core, thus well solve the heat dissipation problem of rotor core and rotating shaft.
The utility model is set to further: the first louvre all arranges along the axis of rotor core and runs through rotor core, and the second louvre and rotating shaft are coaxially arranged, and between the first louvre and the second louvre, conducting is connected with connecting hole.
By adopting technique scheme, first louvre and the second louvre are by connecting hole mutual conduction, the thermal current that rotating shaft and rotor core produce can be made to have better mobility, this thermal current can be passed to rotor body outside by the first louvre and the second louvre, thus play radiating effect.
The utility model is set to further: the second louvre is outwardly communicated with and is provided with ventilation hole.
By adopting technique scheme, the second louvre being provided with ventilation hole, the air-flow of the air-flow between the first louvre and the second louvre and rotor body outside can be made to have better circulation.
The utility model is set to further: shaft hole inwall offers groove, and in rotating shaft, respective slot is provided with raised line.
By adopting technique scheme, the inwall of shaft hole arranges groove and raised line is set in rotating shaft, to rotor core and rotating shaft be located, with the conducting facilitating connecting hole, thus ensure the moment conducting of the first louvre and the second louvre, and then ensure effective air flow property, play radiating effect.
The utility model is set to further: the first louvre is uniformly distributed in the surrounding of shaft hole.
By adopting technique scheme, the first louvre being evenly distributed in the surrounding of shaft hole, being to make the uniformity of heat dissipation ventilation better, thus increasing the effect of heat radiation.
Compared with prior art, the utility model has the advantage of: in rotor core, offer the first louvre, rotating shaft offers the second louvre, and the first louvre and the second louvre mutual conduction, therefore when this rotor body rotates heat production, rotating shaft and rotor core produce heat to be delivered in air-flow, simultaneously because the mutual conduction of the first louvre and the second louvre is arranged, with the quick circulation character utilizing air-flow when rotor body rotates, thermal current can under the circulation effect of air-flow, circulate away from rotating shaft and rotor core, thus well solve the heat dissipation problem of rotor core and rotating shaft.
