Its workflow is：Setting signal passes through system master controller, electric machine controller is connected to by D/A converter, electric machine controller is connected with motor, motor is connected with constant displacement pump, then constant displacement pump is connected to hydraulic actuating mechanism, load is eventually connected to, load end is connected to system master controller and forms feedback by sensor.
The hydraulic actuating mechanism is rotary-vane steering gear.
Embodiment 2
As shown in figure 1, direct drive volume control electro-hydraulic servo system is mainly made up of following 3 part：Computer controls part, motor servo speed governing part and hydraulic power mechanism.Computer controls portion collection comes from speed（Displacement）The feedback command signal of sensor is changed, and system master controller is to this instruction comparative analysis, then voltage signal is transferred to electric machine controller, start-up operation is rotated after servomotor receives voltage instruction, constant displacement pump control hydraulic actuating mechanism is further driven to, load can be finally efficiently controlled.System control the forward and reverse of hydraulic actuating mechanism, movement velocity and position are mainly rotating, movement velocity and the duration of runs by changing servomotor.
Embodiment 3
As shown in Fig. 2 the composition structure of direct-drive type rotary-vane steering gear is mainly including RHVC, power pump installation, 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 the working flow and rotation direction of pump, fluid of the outflow with very high pressure flows through the driving rotary work of moving blade 8 of hydraulic lock 5, and rudderpost from pump
9 and moving blade link together, therefore blade just drives the blade rotating operation that is connected with rudderpost once rotating and starting working, and then the direction come about, position, speed are effectively controlled.System closed circuit is made up of two parts of two-way quantitative pump and blade rotating motor, when the fluid of blade rotating motor output flows through hydraulic lock, hydraulic lock opens valve because oil pressure is acted on allows fluid to flow through, fluid just flows into pumping hole, seal-off pressure oil tank 3 and the two parts of Fill valve 4 in oil circuit are used as the repairing element of whole system, hydraulic lock 5 and stop valve 6 collectively form the safety oil-way in whole loop, and this loop is two-way, this structure can improve the safe and reliable property of system.The flow of two-way quantitative pump has critically important influence for the rotating speed of steering wheel, this causes that the advantage of servo speed adjusting gear has obtained utilizing well, traditional steering wheel mechanism uses electrohydraulic servo valve, and the valve is susceptible to catching phenomenon, therefore with two-way quantitative pump come instead of its work, so that the service behaviour of system has been effectively improved.
1.
Servo speed governing link
Servomotor speed adjusting gear, as direct drive type volume steering gear system power source, is the core texture of whole system.Servo speed adjusting gear is collectively formed by AC servomotor with driver, driver receives the control instruction for coming from the output of computer controls mechanism, the signal that driver will be received is exported after being changed in the form of voltage signal, after AC servomotor receives this voltage signal, can be instructed according to electric signal, correspondingly adjust motor rotation direction, velocity of rotation.
Driver be one can be with the drive system of governing speed, it is mainly made up of three parts：Rectification circuit, it is important that being dc power by the power conversion worked under power frequency；Flat wave circuit, is mainly used for the voltage pulsation that removal is produced in alternative current mechanism and inverter mechanism；Inverter circuit, Main Function is that dc power is changed into AC power.It can be such that the rotating speed of AC servo motor correspondingly changes according to actual needs, and power semiconductor device major advantage is exactly with on-off function.In systems; AC servo motor includes soft start; FREQUENCY CONTROL, speed regulation etc. are that trouble-free operation work is reached by driver in interior correlation function; by the correct utilization of driver; motor is not in be gone 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 is also improved.
AC servomotor, effect is to convert electrical energy into mechanical energy.The structure of AC servomotor is distributed stator winding and also has a rotating armature or rotor to constitute by an electromagnetism winding, 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 controling winding, and another is field winding.The operation principle of AC servomotor：Hot-wire coil winding is rotated in magnetic field can be subject to magnetic field force, it is possible to converting electrical energy into mechanical energy.
2.
Power pump installation
For whole system, the power source that power pump machanism works as whole steering gear system is very important structure, by two-way quantitative pump group into.Two-way quantitative pump being capable of Double-directional rotary, instead of the function of reversal valve realization, problem caused by the pressure change occurred due to changing direction during using reversal valve so would not also occur, the noise of system is also improved, and because the hydraulic circuit of system tails off, so that system takes up space, also weight reduces a lot, so that the performance of system is effectively improved.
3.
Blade rotating motor
Linked 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, so rotary blade type motor can be rotated by blade and being driven rudder stock to rotate and then being caused that rudder blade is rotated.The slewing area of two-piece type rotary-vane steering gear is -35 ° to+35 °, and three-chip type rotary-vane steering gear can go to+38 ° by -38 °.Its operation principle is introduced by taking three-chip type blade rotating motor as an example, rotary blade type helm is mainly by rubber buffer device on hull, three rotating vanes link together with rudder stock, cylinder interior is separated by six small spaces, when through oil pipe by wherein three absorption fluid, when discharging fluid from the other three, blade just promotes rudder stock and rudder blade to rotate under fluid high pressure.
The method that this kind of cylinder body type transmission mechanism can either be also linked together using this method of retaining ring using fluid pressure line, rudder stock and rudder blade, so cause that the contact of rudder blade bearing surface does not rely on the deviation to axis, so whether accurately can make excessive demands not necessarily with too high in for rudder blade bearing when assembling, rudder stock and the active force between coming about are also reduced simultaneously, and degree of lubrication between oil cylinder inside increased.And the service life of bearing is extended, this is that this also effectively increases the performance of system because bearing surface hydraulic oil is to its lubrication.
4.
Feedback device
Feedback device is used for feeding back control signal in systems.Feedback-system section mainly includes that control system, rotation angle sensor, rudder angle deviate limit switch and speed feedback device within the system, the part of feedback device and feedback signal both can be with independently installed, can also integrative installation technology, the device drives by chain or belt transmission to rotor.When rudder stock rotary work, rotational angle when rudder stock works is sent at potentiometer and limit switch trigger control device by the drive shaft of rotation angle sensor, the signal that reception comes can be processed afterwards and be fed back to input again, moment twice before rotor goes to mechanical stop position, triggering cam can be adjusted to position now, and steering command signal can be interrupted.
