Description
Technical field
The present invention relates to Propeller technology field, and in particular to a kind of new coaxial double-rotary swing device and its implementation method.
Background technology
If for submarine navigation device only with single screw advance, the reaction force acts of water in paddle, except generation makes
Outside the forward motive force of ROV, the turning moment of circumferencial direction can be also produced.Therefore, the advance attitude of ROV is also difficult to protect
Hold, so as to influence the efficiency of promoting comprehensively moved ahead with system of ROV.Therefore the torpedo or long-range from boat water advanced with propeller
The big polyisocyanate of thunder turns to double-propeller structure, and two propellers are located at same axis, and two groups of propellers of special requirement with same
Rotating speed and torque opposite direction rotate.Its major advantage has：Oar can completely or partially absorb the rotating energy of bow oar wake flow afterwards, from
And obtain propulsive efficiency higher；Two propellers are common when rotating to produce the motive force for making submarine navigation device forward, and they are produced
The turning moment of raw circumferencial direction is cancelled each other, and phenomenon is sidewindered so as to effectively prevent middle-size and small-size submarine navigation device, it is ensured that
The advance attitude of ROV, improves the operational efficiency of system.
All it is co-axial contra rotating propeller with propeller major part aboard in terms of aviation.Because single group blade
Design can make aircraft be gone off course because of the turn-back torque that propeller rotation is produced, and engineer is typically by regulation aileron
Carry out " trim " this tilting force, that is, make aircraft or so aileron angle of pitch different, produce the power for overcoming upset, finally make
Aircraft keeps level.But the size of this tilting force is changed with the even change of wind direction of flying speed, heading,
So aileron must be adjusted and then, this just increases the technical difficulty of aileron design.Using two groups of coaxial tandems of counter rotating propeller
Design the torsional moment that this two groups of propellers are produced mutually is balanced each other, aircraft would not be subject to the power turned on one's side so that
Contribute to the stability of aircraft flight.In the case of to turning oar and conventional single-blade diameter identical, to turning oar optimum speed than general
Logical single-blade is much smaller, and the common single-blade of optimum diameter ratio to turning oar is also small.
The electric drive twin screw device that current home and abroad is used mainly has three classes：
1. two propeller counter rotatings are dragged by two independent regular alternating currents or direct current generator, this type of drive is former
Reason is fairly simple, but transmission system is relatively costly.Current such drive device is widely used in large ship propulsion system.
2. rotated by the planetary transmission system dragging co-axial contra rotating propeller of separate unit regular alternating current or direct current generator+complexity,
Its complicated gear reduction unit transmission system should realize mechanical reduction, complete to be input to two machineries from a mechanical mouth again
" the machinery fission " of mouth output, then directly drives co-axial contra rotating propeller to rotate by inside and outside cardan shaft, causes its mechanical drive department
Divide more complicated, and machinery driving efficiency is relatively low.
3. driven using the permanent magnet direct current motor of special construction, current China packet header Chang'an magneto researches and develops limited public affairs
Department's this motor of production, and apply in ROV propulsion system under water.Electric machine structure is followed successively by " interior turn from inside to outside
Son, outer rotor, stator ", mechanical output form is exported for single-ended double-shaft concentric formula.The operation logic and Conventional permanent magnet of such motor
Direct current generator is identical, simply allows the stator of Conventional permanent magnet direct current generator also to rotate, and becomes outer rotor, and in the outermost of motor
Face increased and be not involved in electromechanical energy conversion, be served only for the outer mechanical stator of mechanical support.This is to include torpedo and long-range from boat
Submarine mine motor with the most use in interior middle-size and small-size co-axial contra rotating propeller submarine navigation device.Compared with first two situation, it is
System structure obtains certain simplification, and volume and weight is reduced to a certain extent, but with commutator, slip ring and two sets
Brushgear, on the one hand greatly reduces the operational reliability of motor；Another aspect motor cost is higher, and structure still shows complexity,
In addition it is used purely for the outer mechanical stator of mechanical support so that the volume of motor is still larger.
