Description
Technical field:
The present invention relates to a kind of wind tunnel fan driving device.
Background technology:
The wind tunnel fan driving device that uses is that case (speed-changing gear box) system, lubricating system, cooling system, wind-tunnel hole body, wind straighter cover, straightening vane ring and impeller 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 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 lead 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; Lubricating system is installed again; Straightening vane ring and radome fairing are installed respectively; The 2nd straightening vane ring is installed behind the good impeller to be installed again; Install the radome fairing front shroud at the front end of device again; Blower fan with cooling system is installed on the cooling duct 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, manufacturing cost is high, the energy resource consumption waste seriously.Axle wherein is that the turnover oil-piping of case (speed-changing gear box) system, lubricating system and the airduct road of cooling system all influence bigger to tunnel airstream, increased the gas-flow resistance of wind-tunnel, cause the work 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 serviceable life of equipment.
Summary of the invention
Purpose of the present invention 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 object of the present invention is achieved like this: a kind of wind tunnel fan driving device, and it comprises the wind straighter cover and the impeller that winding stator 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 threephase asynchronous, the winding stator 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 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 among the present invention, 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 through magnetic field energy, and rotor is exported impeller work with the form of mechanical energy from rotating shaft then.Because the motor among the present invention is a frequency control motor, also can come the rotating speed of converting motor by the frequency converter regulating frequency.
Beneficial effect of the present invention is:
1, the drive motor among the present invention is owing to adopted the frequency control 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 case speed change) and lubricating system (gear case is lubricated), make it save 10% steel, reduced by 15% manufacturing cost.
2, because the drive motor among the present invention is to fixedly connected with the cover body inwall of above-mentioned wind straighter cover by its winding stator core, 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 among the present invention 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 among the present invention is again the wind straighter cover among the present invention; Simultaneously, among the present invention impeller directly is fixedly connected on the rotating shaft shaft extension of above-mentioned drive motor rotor, dwindled overall volume of the present invention, make that drive motor and wind-tunnel hole body have formed an integral body among the present invention, 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, cancel cooling system of the prior art, one-piece construction of the present invention and manufacturing process are tending towards simply, further reduced manufacturing cost again.
Therefore, the present invention just can just be 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 volume of the present invention and manufacturing process.The present invention has avoided the oil contamination of wind-tunnel hole body and to the influence of tunnel airstream, the serviceable life of having improved equipment; Improved the work efficiency of apparatus of the present invention systems, the test for aircraft, guided missile, torpedo, spacecraft, automobile, bridge etc. has simultaneously improved test accuracy.
