Embodiment
The present invention is further detailed explanation with specific embodiment below in conjunction with the accompanying drawings, is not the reality the present invention
Apply scope and be confined to this.
As shown in Figures 1 to 5, a kind of servomotor described in the present embodiment, includes motor body and main shaft 11, institute
Main shaft is stated provided with heat abstractor.
The heat abstractor includes：
Include the heat conduction circle 31 being socketed on main shaft 11, heat conduction circle 31, which outwardly extends, multigroup radiating vane group
Close, every group of radiating vane combination includes two fin be arrangeding in parallel 33；Also include discoid heat dissipating housing 21, radiate
Cover 21 is provided with axis hole, and main shaft 11 passes through the axis hole of heat dissipating housing 21, and the back side of heat dissipating housing 21 is provided with multiple air inlets 32, air inlet 32
On air inlet pipe 23 is installed；The top surface of the back side of heat dissipating housing 21 and motor is fixed by connecting rod 24；Also include for that will radiate
Axis hole also is provided with the cover plate 22 that cover 21 is sealed, cover plate 22, main shaft 11 is passed through on the axis hole of cover plate 22, each fin 33
It is equipped with heat emission hole 34.Heat conduction circle 31 and fin 33 are formed in one, and the heat conduction circle 31 and fin 33 are that aluminium is closed
Golden material.
Specifically, cold wind is constantly blowed in heat dissipating housing 21 by air inlet pipe 23, and when motor rotates, multigroup heat emission fan
Heat, is constantly dispersed among cold wind by the rotation of leaf combination, and cold wind dissipates in the space between the axis hole of cover plate 22 and main shaft 11
Go out.
In multigroup radiating vane combination of the present invention, every group of radiating vane combination has two fin 33, two fin
33 during cold wind is blown, and certain flow-disturbing is produced between two fin 33, allows cold wind contact and residence time more
It is long, it is highly effective while reduce energy consumption, add radiating dynamics.
By wind-cooling heat dissipating mode, the radiating of main shaft 11 can be effectively realized, the temperature of main shaft 11, the double leaf of unique design is reduced
Structure, while can quickly heat be taken away, reduces the air resistance coefficient to main shaft 11, reduces capacity loss.
A kind of servomotor described in the present embodiment, the radiating vane group has four groups altogether, and equidistant be circumferentially positioned at is led
The outer surface of gas ket 31.A kind of servomotor described in the present embodiment, each fin 33 is provided with six heat emission holes 34.This implementation
A kind of servomotor described in example, in one group of radiator shutter combination, the fin 33 close to motor body side is set to first and dissipated
Backing 33, another fin 33 is set to the second fin 33；Heat emission hole 34 and second on first fin 33 radiates
The position all same of the quantity of heat emission hole 34 and setting on piece 33；Heat emission hole 34 on first fin 33, it is first
The diameter of the outer surface of fin 33 is more than its diameter in the inner surface of the first fin 33；Radiating on second fin 33
Hole 34, its outer surface of the second fin 33 diameter be more than its inner surface of the second fin 33 diameter.The present embodiment institute
The diameter and second of heat emission hole 34 on a kind of servomotor stated, first fin 33 in the outer surface of the first fin 33
Diameter of the heat emission hole 34 in the outer surface of the second fin 33 on fin 33 is identical；Heat emission hole on first fin 33
34 heat emission hole 34 on the diameter and the second fin 33 of the inner surface of the first fin 33 is in the inner surface of the second fin 33
Diameter is identical.A kind of servomotor described in the present embodiment, first radiating and heat emission hole 34 on the second fin 33 are big
Small structure is identical, and the inner surface of heat emission hole 34 is curved surface, and its curved surface formula is：, its
Represent, 1（T1, E1）Curved section between point and 2 (T2, E2) points, E2 ＞ E1.
Specifically, producing certain flow-disturbing between two fin 33 to ensure the utilization rate of cold air, but also have one
Fixed windage, the rotating speed and moment of torsion of servomotor is lost.Therefore, the present invention constrains above-mentioned curved surface radian and heat emission hole 34
Shape.Experiment is found, when cold air is blown into from the heat emission hole 34 of the outer surface of the first fin 33 to be come, due to air quilt
Compression, further can reduce the temperature of cold air, that is to say, that the temperature of the air-flow in the middle of to two fin 33 will be more
It is low, then when being excluded from the hole of the inner surface on the second fin 33, pressure reduction discharges certain heat, but due to having arrived
The outside of second fin 33, will be excluded from the axis hole of cover plate 22 at once, therefore the heat of release does not interfere with radiating, instead
And, the degree of heat radiation that two relative heat emission holes are greatly improved between two panels fin 33 for 34 times.In addition, in order to reduce flow-disturbing
Influence of the windage to rotating speed and moment of torsion, the curved surface devised under curved surface formula above, the formula structure can be demonstrate,proved in practice
Bright curved surface air-flow is smooth, can substantially reduce windage.
Described above is only the preferred embodiment of the present invention, therefore all structures according to described in present patent application scope
Make, the equivalent change or modification that feature and principle are done, in the protection domain of present patent application.
