Description
Technical field
The utility model is related to the technical field of motor cooling, especially a kind of motor exhausting type air-cooled structure.
Background technology
The height of motor temperature has extremely important influence to its efficiency and service life, so corresponding drop must be taken
Warm measure.There are two types of electric motor temperature reduction modes：Water cooling and air-cooled, either any type of cooling reaches certain cooling medium
Flow is the premise for realizing electric motor temperature reduction.What most of motor used is all water cooling or combination cooling, seldom using completely air-cooled
Mode.The advantages of water cooling, mainly coolant liquid specific heat capacity was high, and cooling rate is fast, the disadvantage is that auxiliary device is more, needed to be equipped with corresponding
The attachmentes such as circulating pump, cooling fin, water tank, have certain requirement to coolant liquid, and unknown to the cooling-down effect of rotor
It is aobvious.The specific heat capacity of air-cooled middle air is low, and cooling rate is slower, so air-cooled difficult point is how to increase air-cooled amount, generally all
The air cooling equipment of addition external impetus can be taken, complicated, operation stability is poor.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, reasonable design, a kind of electricity overcome the shortage of prior art
Machine exhausting type air-cooled structure.
To achieve the goals above, the technological means that the utility model is taken is：
A kind of motor exhausting type air-cooled structure, including electric machine casing and the stator and rotor that fit within portion, in electricity
Air inlet is provided on casing body, air inlet is distributed with 8 to 12 along electric machine casing even circumferential, a diameter of 10mm of air inlet
To 20mm, key is：Air-cooled impeller is fixed with by shaft coupling at the end cap axle center of electric machine casing tail portion, in air-cooled impeller
External stability have impeller shield, be provided on end cap in a circle ventilation hole and electric machine casing concentric with electric machine main shaft return
Circulation road is connected to, and the diameter of impeller shield is less than the spacing of ventilation hole and electric machine main shaft, in the outside of electric machine casing tail cover
It is fixed with coaxial lid shape and goes out the crust of weathering, air outlet is provided on going out the crust of weathering and is connected to the vent of impeller shield, in leaf
The right end of wheel shield is provided with return port and is connected to the inner space for going out the crust of weathering.
Vent is arranged on the side wall of impeller shield.
Bearing block is provided at the axle center for going out crust of weathering madial wall, the lateral wall of bearing block is inwardly open arc knot
Structure.
It is both provided with sealing ring in the junction and electric machine casing of end cap and impeller shield and the junction for going out the crust of weathering.
The utility model has the beneficial effects that：
1, active air-cooled structure is not necessarily to external impetus：Air-cooled impeller is installed on rotor tail end, passes through air-cooled impeller
Rotation, be discharged return duct in gas simultaneously negative pressure is formed inside return duct, ambient atmos are under the action of the negative pressure by electricity
Machine hull outside is flowed into inside electric machine casing, forms air-cooled cycle, and air-cooled amount is only related with the rotating speed of rotor, it is general and
Speech, rotating speed more high power is also bigger, and air-cooled amount at this time is also bigger, then smaller on the contrary；
2, exhausting type air-cooled structure promotes compression efficiency：Flow through this part high-temperature gas that air-cooled channel is electric motor temperature reduction
It is not discharged into air blower box house, but is discharged into outside air blast chassis body by discharge pipe and external pipe, this sets
Meter avoids the raising of air blower box interior temperature and entrance temperature, improves the compression effect of impeller to a certain extent
Rate.
