Description
Technical field
The utility model is related to Propeller technology field, and in particular to a kind of new coaxial incorgruous twin screw device.
Background technology
If promoted for submarine navigation device only with single screw, the reaction force acts of water are in blade, except generation makes
Outside the forward motive force of ROV, the turning moment of circumferencial direction can be also produced.Therefore, the advance posture 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 promoted 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 are with same
Rotating speed and the rotation of torque opposite direction.Its major advantage has：Oar can completely or partially absorb the rotating energy of bow oar wake flow afterwards, from
And obtain higher propulsive efficiency；Common during two propeller rotations to produce the motive force for making submarine navigation device forward, they are produced
The turning moment of raw circumferencial direction cancels each other, so that effectively prevent middle-size and small-size submarine navigation device sidewinders phenomenon, it is ensured that
The advance posture of ROV, improves the operational efficiency of system.
In terms of aviation, most of with propeller aboard is all co-axial contra rotating propeller.Because single group blade
Design can make aircraft be gone off course because propeller rotates the turn-back torque 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 torsional moment that this two groups of propellers can just produced mutually balance each other, aircraft would not by 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, also small to the common single-blade of optimum diameter ratio that turns oar.
The electric drive twin screw device that current home and abroad is used mainly has three classes：
1. dragging two propeller counter rotatings by two independent regular alternating currents or direct current generator, this type of drive is former
Reason is fairly simple, but transmission system cost is higher.Current such drive device is widely used in large ship propulsion system.
2. by separate unit regular alternating current or the dragging co-axial contra rotating propeller rotation of the planetary transmission system of 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, causes its mechanical drive department by inside and outside cardan shaft
Divide more complicated, and machinery driving efficiency is relatively low.
3. being driven using the permanent magnet direct current motor of special construction, current China packet header Chang'an magneto researches and develops limited public affairs
This motor of department's production, and applied under water in ROV propulsion system.Electric machine structure is followed successively by " interior turn from inside to outside
Son, outer rotor, stator ", mechanical output form exports 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, which is added, is not involved in electromechanical energy conversion, is served only for the outer mechanical stator of mechanical support.This is to include torpedo and long-range from boat
Motor with the most use in middle-size and small-size co-axial contra rotating propeller submarine navigation device including submarine mine.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.
