Embodiment 2
As it is shown in figure 1, directly driven volume controlled electro-hydraulic servo device is mainly made up of following 3 parts: computer controls part, motor servo speed governing part and hydraulic power mechanism.Computer control portion collection comes from the feedback command signal of speed (displacement) sensor to be changed, and device master controller instructs comparative analysis to this, then voltage signal is transferred to electric machine controller, servomotor is started working after receiving voltage instruction rotation, it is further driven to dosing pump and controls hydraulic actuating mechanism, finally can efficiently control load.Forward and reverse, the movement velocity of device control hydraulic actuating mechanism and position are mainly by changing the rotating of servomotor, movement velocity and the duration of runs.
Embodiment 3
As in figure 2 it is shown, the composition structure of direct-drive type rotary-vane steering gear mainly includes RHVC, kinetic pump device, blade rotating motor, feedback device, various valve members etc..
After servomotor 1 receives Setting signal, drive two-way quantitative pump 2 to rotate based on semaphore request to bring into operation, the velocity of rotation of servomotor, rotation direction and rotation time have decisive role for working flow and the rotation direction of pump, flow out from pump and there is the fluid of very high pressure flow through hydraulic lock 5 and drive moving blade 8 rotary work, and rudderpost 9 and moving blade link together, therefore blade once rotates the blade rotating operation that just drive is connected of starting working with rudderpost, and then direction, position, the speed come about are effectively controlled.Device closed circuit is made up of two-way quantitative pump and two parts of blade rotating motor, the when that the fluid of blade rotating motor output flowing through hydraulic lock, hydraulic lock is opened valve and is allowed fluid to flow through due to oil pressure effect, fluid just flows to pumping hole, seal-off pressure oil tank 3 in oil circuit and Fill valve 4 two parts are used as the repairing element of whole device, hydraulic lock 5 and stop valve 6 collectively form the safety oil-way in whole loop, and this loop is two-way, and this structure can make the safe and reliable property of device improve.The flow of two-way quantitative pump has critically important impact for the rotating speed of steering wheel, this makes the advantage of servo speed adjusting gear obtain well to utilize, conventional rudder machine mechanism uses electrohydraulic servo valve, and this valve is susceptible to catching phenomenon, therefore replace its work with two-way quantitative pump, so make the service behaviour of device be effectively improved.
1. servo speed governing link
Servomotor speed adjusting gear, as direct drive type volume helm gear power source, is the core texture of whole device.Servo speed adjusting gear is collectively formed with driver by AC servomotor, driver receives the control instruction coming from the output of computer controlled machine structure, driver exports with the form of voltage signal after being changed by the signal received, after AC servomotor receives this voltage signal, can instruct according to the signal of telecommunication, correspondingly adjust motor rotation direction, velocity of rotation.
Driver be one can be with the driving means of governing speed, it is mainly made up of three parts: rectification circuit, it is important that be dc power by the power conversion worked under power frequency；Flat wave circuit, is mainly used for removing the voltage pulsation produced in alternative current mechanism and inverter mechanism；Inverter circuit, Main Function is that dc power is changed into AC power.It can make the rotating speed of AC servo motor the most correspondingly change, and power semiconductor device major advantage has on-off function exactly.In a device; AC servo motor includes soft start; FREQUENCY CONTROL, speed regulation etc. all reach trouble-free operation by driver at interior correlation function and work; by the correct utilization of driver; motor does not haves and goes wrong because of overvoltage, overcurrent, overload and power factor change or wave phenomenon occur; so AC servo motor is protected, and the control sensitivity of motor have also been obtained raising.
AC servomotor, effect is to convert electrical energy into mechanical energy.The structure of AC servomotor is by an electromagnetism winding or distribution stator winding also has a rotating armature or rotor is constituted, electromagnetism winding or stator winding act as producing magnetic field, in stator core, with the presence of two phase windings in space form at a right angle, one is control winding, and another is field winding.The operation principle of AC servomotor: hot-wire coil winding rotates in magnetic field can be by magnetic field force, it is possible to convert electrical energy into mechanical energy.
2. kinetic pump device
For whole device, the power source that kinetic pump mechanism works as whole helm gear, it is very important structure, is made up of two-way quantitative pump.Two-way quantitative pump can Double-directional rotary, instead of the function that reversal valve realizes, the most also would not occur that the pressure occurred owing to changing direction when using reversal valve changes the problem caused, the noise of device have also been obtained improvement, and owing to the hydraulic circuit of device tails off, make the device also weight that taken up space reduce a lot, thus the performance of device is effectively improved.
3. blade rotating motor
Link together with rudder stock in the middle of the oil cylinder of rotary blade type motor, and what rudder stock and rudder blade were also connected together, drive rudder stock rotate and then rudder blade is rotated so rotary blade type motor can be rotated by blade.The slewing area of two-piece type rotary-vane steering gear is-35 ° to+35 °, and three-chip type rotary-vane steering gear can be forwarded to+38 ° by-38 °.Its operation principle is introduced as a example by three-chip type blade rotating motor, rotary blade type helm mainly relies on rubber buffer device to be arranged on hull, three rotating vanes link together with rudder stock, cylinder interior is separated by six little spaces, when being absorbed fluid through oil pipe by wherein three, when the other three discharges fluid, blade just promotes rudder stock and rudder blade to rotate under fluid high pressure.
This kind of cylinder body type drive mechanism can either utilize the method that this method of retaining ring also is able to utilize fluid pressure line, rudder stock and rudder blade to be linked together, the contact so making rudder blade bearing surface does not relies on the deviation to axis, so whether can accurately centering make excessive demands not necessarily with too high for rudder blade bearing assembling when, rudder stock and the active force between coming about also reduce simultaneously, and between oil cylinder inside degree of lubrication add.And extend the service life of bearing, this is that this is also effectively increased the performance of device due to the bearing surface hydraulic oil lubrication to it.
4. feedback device
Feedback device is used for feeding back control signal in a device.Feedback-system section mainly includes controlling device, rotation angle sensor, rudder angle deviation limit switch and speed feedback device in the apparatus, the parts of feedback device and feedback signal both can be independently installed, can also integrative installation technology, this device is driven on rotor by chain or belt transmission.When rudder stock rotary work when, rotational angle during rudder stock work is sent to potentiometer by the drive shaft of rotation angle sensor and controls at equipment with limit switch trigger, the signal that reception is next can be carried out processing afterwards and feed back to input again, moment twice before rotor forwards mechanical stop position to, trigger cam and can be adjusted to position now, and steering command signal can be interrupted.
