Abstract
The utility model discloses a heat radiation housing of a high speed motor. The heat radiation housing comprises a motor housing which is arranged in a cover body. A fan driven by a motor shaft is mounted on the end of the cover body. A plurality of through slots for wind to circulate concaved inwardly are arranged on the motor housing. When the high speed motor is working, the motor shaft drives the fan to rotate, high speed rotation of the fan enables the wind to flow out or flow in from a channel, hence the heat on the motor housing is taken away, and working temperature of the high speed motor can be greatly reduced. The dust in the motor housing cannot enter, temperature can be reduced fast and efficiently, meanwhile the heat radiation structure is easy to dismount and low in cost.
Description
Technical field
The utility model relates to a kind of structure of motor, more precisely, relates to a kind of radiating shell of high-speed electric expreess locomotive, is applicable to the needs high-revolving driving fields such as negative pressure device generator.
Background technology
Depression generator drives by motor conventionally, and its rotating speed is more than 2000 revs/min.Can there are a lot of problems in the motor of high speed rotating, for example efficiency is not high, rotation is steady, moment of torsion is little, makes the vibration of motor rotation large, and noise is high.
The heat dissipation problem of motor is perplexing people always, and the heat radiation of motor in prior art, generally all adopts radiating ribs is set on casing, increases the area of dissipation of motor, but the efficiency of this radiator structure is extremely low.In prior art, also have a kind of cooling mechanism, at motor internal provided with fan, this cooling mechanism need to make motor internal be in communication with the outside, so that heat radiation, although this scheme radiating effect is relatively good, dust easily enters into motor internal, thereby affects the useful life of motor.
Utility model content
The utility model, in order to solve problems of the prior art, provides a kind of radiating shell of high-speed electric expreess locomotive.
In order to realize above-mentioned object, the technical solution of the utility model is: a kind of radiating shell of high-speed electric expreess locomotive, comprise motor casing, described motor casing is arranged in body, the termination of described body is provided with the shaft-driven fan of motor, and described motor casing is provided with the groove for wind circulation that multiple tracks indent forms.
Preferably, the quantity of described groove is four, lays respectively at the edges and corners of cuboid motor casing.
When high-speed electric expreess locomotive is when working, motor shaft drive fan is rotated, and the high speed rotating of fan makes wind from groove, flow out or flow into, thereby the heat on motor casing is taken away, and significantly reduces the working temperature of high-speed electric expreess locomotive.Can not make dust enter into motor casing inside, again can be fast, temperature with high efficiency, meanwhile, and this radiator structure easy accessibility, with low cost.

Embodiment
For the technical problem that the utility model is solved, the technical scheme of employing, the technique effect easy to understand of obtaining, below in conjunction with concrete accompanying drawing, embodiment of the present utility model is described further.
Referring to figs. 1 to Fig. 3, the utility model discloses a kind of high-speed electric expreess locomotive, comprise stator 1, motor shaft 4 and be arranged on the rotor on motor shaft 4, rotor of the present utility model has two, be designated as respectively the first rotor 2 and the second rotor 3, two rotors share a motor shaft 4, and assemble by technology known in the field.The first rotor 2 and the second rotor 3 coordinate with two ends of stator 1 respectively; Reference-view direction, the first rotor 2 is assemblied in the left end of stator 1, with the left end matched in clearance of stator 1; The second rotor 3 is assemblied in the right-hand member of stator 1, with the right-hand end matched in clearance of stator 1.
The first rotor 2 is identical with the structure of the second rotor 3, take the first rotor 1 as example, and it is conical that described the first stator 2 is, and the end of described stator 1 is also the taper shape with the first rotor 2 matched in clearance, has one and is conical inner concave 11.
High-speed electric expreess locomotive of the present utility model, the structure of two rotors of employing, coordinates with the gap between two ends of stator respectively, and the clearance plane of its cooperation is coniform, and such structure makes this motor can obtain larger moment of torsion, moves more steady.
Rotor in the utility model, stator can adopt public structure well known in the art, such as rotor, comprise iron core 21 and paste magnet 22 on iron core 21 etc., also have winding on stator and stator etc., all can adopt public material well known in the art.For example magnet can adopt rare earth permanent-magnetic material, and remanent magnetism is high, coercive force is high, and iron core adopts mild steel to manufacture etc.
The invention also discloses a kind of radiating shell of high-speed electric expreess locomotive, with reference to figure 4, also comprise motor casing 5, stator 1, motor shaft 4, rotor are all arranged in this motor casing 5, described motor casing 5 is arranged in body 6, and this body 6 also can be regarded a sleeve as, by screw, itself and motor casing 5 is fixed together, the termination of described body 6 is provided with the fan 61 that motor shaft 4 drives, and described motor casing 5 is provided with the groove 51 for wind circulation that multiple tracks indent forms.
When high-speed electric expreess locomotive is when working, motor shaft 4 drive fan 61 are rotated, and the high speed rotating of fan 61 makes wind from groove, flow out or flow into, thereby the heat on motor casing 5 is taken away, and significantly reduces the working temperature of high-speed electric expreess locomotive.Can not make dust enter into motor casing 5 inside, again can be fast, temperature with high efficiency, meanwhile, and this radiator structure easy accessibility, with low cost.
In preferred embodiment of the utility model, the quantity of described groove 51 is four, lays respectively at the edges and corners of cuboid motor casing 5.
In embodiment of the present utility model, fan in a kind of high-speed electric expreess locomotive radiating shell is also provided, with reference to figure 5, comprise 7 blades that distribute along circumference of hub direction, blade described in seven deciles radially, six sectional tools that form have following shape: the angle of described six sections and horizontal plane is followed successively by 36.25 °, 34.95 °, 31.12 °, 28.81 °, 27.26 °, 26.51 °, and the angle between adjacent two blades is followed successively by 54 °, 50 °, 47.75 °, 50.23 °, 54.25 °, 50 ° 77,53 °.The blade of this structure, can make the caused noise of blade be distributed in wider frequency band, has less windage, capable of reducing energy consumption, can not cause excessive burden to motor.
