Technical field:
The utility model relates to a kind of wind tunnel fan driving device.
Background technique:
The wind tunnel fan driving device that uses is that case (speed-changing gear box) system, lubrication system, cooling system, wind-tunnel hole body, wind straighter cover, impeller and straightening vane ring are formed by drive system, axle at present.The structure assembly relation that is existing wind tunnel fan driving device is: assemble a drive unit dress on request, it is drive motor, it is the common threephase asynchronous of a complete band support shell, again with its complete being fit in the body of hole, with bolt itself and wind-tunnel hole body are drawn the hole body with power line after fastening by motor flange seam and mounting hole; On the shaft extension of this motor shaft joint is installed, the other end of shaft joint is that case is connected (axle is that case comprises parts such as casing, gear, end cap, oil cap, axle) with the axle that assembling finishes; Lubrication system is installed again; Straightening vane ring and cowling are installed respectively; The 2nd straightening vane ring is installed behind the good impeller to be installed again; Install the cowling front shroud at the front end of device again; Blower fan with cooling system is installed on the cooling pipe and the line of connecting with the mains then, and the power supply with drive unit connects at last, and energising can move.This install not only volume big and whole apparatus structure is loaded down with trivial details in a jumble, make the assembly technology difficulty, consumptive material is many, manufacture cost is high, the energy consumption waste seriously.Axle wherein is that the turnover oil-piping of case (speed-changing gear box) system, lubrication system and the airduct road of cooling system all influence bigger to tunnel airstream, increased the gas-flow resistance of wind-tunnel, cause the working efficiency of whole device to reduce, the precision that is used for wind tunnel test reduces.And lubricant mist is especially serious to the pollution of wind-tunnel, has significantly reduced the working life of equipment.
Summary of the invention
The purpose of this utility model just is to provide that a kind of volume is little, structure and manufacturing process is simple and the wind tunnel fan driving device of low cost of manufacture.
The purpose of this utility model is achieved in that a kind of wind tunnel fan driving device, and it comprises the wind straighter cover and the impeller that winding stator iron core, rotor, shaft extension end end cap and non-shaft stretching end end cap are arranged, be connected with above-mentioned drive motor on drive motor, the above-mentioned drive motor; It is characterized in that above-mentioned drive motor is the frequency control of motor speed threephase asynchronous, the winding stator iron core that has of above-mentioned drive motor is fixedlyed connected with the cover body inwall of above-mentioned wind straighter cover; The shaft extension end end cap at the rotating shaft two ends of above-mentioned drive motor upper rotor part is fixedlyed connected with the two ends of above-mentioned cover body respectively with the non-shaft stretching end end cap.
It is above-mentioned that the winding stator iron core and the inwall of above-mentioned cover body are arranged is that interference fit is connected; The shaft extension end end cap at the rotating shaft two ends of above-mentioned rotor and non-shaft stretching end end cap cooperate with the seam at above-mentioned cover body two ends respectively, and connect through bolt.
Above-mentioned impeller directly is fixedly connected on the rotating shaft shaft extension of above-mentioned drive motor rotor.
When feeding the three-phase symmetrical current in three phase windings of the motor stator in the utility model, in stator, rotor airgap, will produce a rotating magnetic field, conversion is delivered to rotor to the electric energy that stator is obtained from ac power supply through magnetic field energy, and rotor is exported impeller work with the form of mechanical energy from rotating shaft then.Because the motor in the utility model is a frequency control motor, also can come the rotating speed of converting motor by the frequency variator regulating frequency.
The beneficial effects of the utility model are:
1, the drive motor in the utility model is owing to adopted the frequency control of motor speed threephase asynchronous, not only reduced about 33% electric energy, but also cancelled the axle that plays chronotropic action in the prior art is case system (gear-box speed change) and lubrication system (gear-box is lubricated), make it save 10% steel, reduced by 15% manufacture cost.
2, because the drive motor in the utility model is to have the winding stator iron core to fixedly connected with the cover body inwall of above-mentioned wind straighter cover by it, the shaft extension end end cap at the rotating shaft two ends of drive motor upper rotor part is fixedlyed connected with the two ends of above-mentioned cover body respectively with the non-shaft stretching end end cap, drive motor in the utility model has just saved drive motor support shell in the prior art like this, and the support shell that the wind straighter cover is optimized for be drive motor in the utility model is again the wind straighter cover in the utility model; Simultaneously, in the utility model impeller directly is fixedly connected on the rotating shaft shaft extension of above-mentioned drive motor rotor, dwindled overall volume of the present utility model, make that drive motor and wind-tunnel hole body have formed an integral body in the utility model, so the air quantity in the wind-tunnel hole body that impeller is produced can directly utilize wind tunnel test the time is to the drive motor cooling processing of dispelling the heat, so cancelled cooling system of the prior art, overall structure of the present utility model and manufacturing process are tending towards simply, have further reduced manufacture cost again.
Therefore, the utility model just just is made up of above-mentioned drive motor, wind straighter cover, impeller and straightening vane ring.
In a word, simple, the low cost of manufacture of little, structure of the utility model volume and manufacturing process.The utility model has been avoided the oil pollution of wind-tunnel hole body and to the influence of tunnel airstream, the working life of having improved equipment; Improved the working efficiency of the utility model apparatus system, the test for aircraft, guided missile, torpedo, astrovehicle, automobile, bridge etc. has simultaneously improved test accuracy.
