Description
Technical field
The utility model belongs to field of electromechanical technology, is related to a kind of motor, good asynchronous of more particularly to a kind of thermal diffusivity
Motor.
Background technology
Asynchronous machine is most widely used motor in people's daily life, is that a variety of plant equipment and household electrical appliance are carried
For power.Such as lathe, middle-size and small-size steel rolling equipment, blower fan, water pump, light industry and machinery, metallurgy and mining machinery.
Asynchronous motor can operationally generate heat, and this is accomplished by motor installing radiator structure additional, otherwise exist for a long time
The motor insulating barrier worked under high temperature can accelerate aging influence electrical machinery life, or even motor is burnt.In order to motor
Cooling, asynchronous machine temperature is radiated by setting up radiating ribs on housing, in motor rear end plate and heat dissipation air hood
Between fan is installed additional to increase radiating rate.
But in the prior art, the fan between motor rear end plate and heat dissipation air hood can only radiate to rear end cap, it is impossible to
Electric machine casing and terminal box are radiated.The radiating of housing can only be radiated by radiating ribs in conjunction, in terminal box
The device such as electric capacity can only also lean on natural heat dissipation.Because the working time of motor is longer, cause its radiating rate not catch up with, dissipate
Hot area is smaller, influences its working condition.And the opening director of heat dissipation air hood contacts the phase with the external world, gets rusty easily rotten.
The content of the invention
The purpose of this utility model is, there is provided one kind is rational in infrastructure, to dissipate for the above-mentioned problems in the prior art
The good asynchronous motor of the good thermal diffusivity of thermal effect.
The purpose of this utility model can be realized by following technical proposal：A kind of good asynchronous motor of thermal diffusivity, bag
Casing, the rotating shaft being arranged in casing are included, and is installed on the drive end bearing bracket and rear end cap at the forward and backward both ends of casing, described machine
Be provided with shell it is evenly spaced on terminal box, the periphery wall of casing be distributed with some radiating ribs, the two ends point of the rotating shaft
Do not pass drive end bearing bracket and rear end cap, and rotating shaft passes the end of rear end cap and is fixed with fan, described rear end cap and is provided with
Fan can be wrapped in interior heat dissipation air hood, it is characterised in that the outer ring of described rear end cap is provided with installs for heat dissipation air hood
Wheel rim, the support column being distributed between described wheel rim and the outer ring of rear end cap by some uniform intervals is fixedly connected with, and if
Dry root support column will form the ventilating opening of respective numbers, the axis projection position of described part radiating ribs between rear end cap and wheel rim
In in the axis projection of ventilating opening, the part axis projection of described terminal box also is located in the axis projection of ventilating opening.
In a kind of good asynchronous motor of above-mentioned thermal diffusivity, screw thread phase is passed through between described heat dissipation air hood and wheel rim
Connection, the inner end of the wheel rim has the spacing boss of the confession heat dissipation air hood of radial protrusion.This structure design not only to dissipate
The dismounting of air bells cap is more convenient, and also avoid port and the contacting external air of heat dissipation air hood, makes its service life longer.
It is one in a kind of good asynchronous motor of above-mentioned thermal diffusivity, between described rear end cap, wheel rim and support column
It is body formed.It is integrally formed so that its structural strength is high.
In a kind of good asynchronous motor of above-mentioned thermal diffusivity, being provided with corresponding support column can be by rear end cap
It is fixed on the fixing screws on casing.Fixing screws are arranged on the support column with rear end cap one, may be such that installation is more convenient.
Compared with prior art, the cold wind that fan rotation is produced in the good asynchronous motor of this thermal diffusivity can pass through ventilating opening
Radiating ribs and terminal box are blown to, the rear end cap of motor is radiated, and can also accelerate dissipating for radiating ribs and terminal box
Heat so that the overall radiating effect of the motor is more preferable.
