Description
Technical field
This patent is related to airplane design manufacturing technology field, especially a kind of hydraulic valve mechanical feedback operating mechanism.
Background technique
Side valve type valve passes through shutdown for controlling oil liquid direction, pressure and flow generally as the component for linking up oil circuit
Valve changes slide valve moving direction to cut off or change the direction of oil liquid, controls the movement that pressure oil enters executing agency with this
Chamber, the motion state and the direction of motion of Lai Shixian executing agency.The valve that manually controls generally used is switched on and off, and executes machine
The movement position of structure is monitored by operator, is judged whether in place by operator and turned off valve, but mechanism kinematic after starting in place
Precision, position accuracy be not high.
However to guarantee the accurate motion of mechanism on machine, realize that driving executing agency moves and it is made to stop at required position
On, therefore control unit is usually designed as two parts, for controlling turning on and off for oil circuit, another part is used for a part
Realize that executing agency can reliably be maintained at required position when controlling oil circuit shutdown.Solenoid valve, position sensing are generallyd use at present
Device etc. carries out the on-off of oil circuit, guarantees being precisely controlled for position, however uses electrical control mechanism higher to attachment reliability requirement, and one
The failure of denier circuit, which will result in mechanism, to be moved.
Therefore for these reasons, spy proposes a kind of operating mechanism of hydraulic valve mechanical feedback, by two kinds of function knots
It closes and links up oil circuit with one, i.e. one side, another aspect feedback function reversely turns off oil circuit, realizes the movement of executing agency and stop
Only.
Summary of the invention
The purpose of the application is to provide a kind of operating mechanism of hydraulic valve mechanical feedback, realizes the drive to executing agency
It is dynamic, and executing agency is maintained at set position by mechanical feedback mechanism when the corresponding position of driving input stops
On.
A kind of hydraulic valve mechanical feedback operating mechanism, including executing agency, feedback mechanism, handwheel, pinion gear group,
Gear wheel, the control-rod with conical sleeve gear shaft, friction plate, ear mount, slide valve, rope arrangement；Feedback mechanism passes through rope arrangement
It is connect with gear wheel, executing agency is crosslinked by rope arrangement and gear wheel, and pinion gear group is made of 3 gears, passes through spiral shell
The connection of bolt and bearing supports, and links together with control-rod and gear wheel, pinion gear group is connected with slide valve by ear mount, hand
Wheel is fixed on control-rod and between the two equipped with friction plate；Rotate handwheel, control-rod rotate driving pinion gear group, wandering star tooth
Wheel group pulls ear mount band movable pulley to open pressure oil circuit, and executing agency moves under the action of pressure oil at this time, pinion gear
Group is slided on gear wheel, keeps hand wheel rotating angle directly proportional to executing agency's angle by the transmission ratio of gear member；Handwheel stops
While only moving, the position signal of executing agency is fed back to feedback mechanism by rope arrangement moment, and drives gear wheel reversed
Rotation, reversed to drive pinion gear group by the feedback of gear wheel, pinion gear group is rolled in the conical sleeve gear shaft of control-rod
Dynamic, control-rod remains stationary, and by pull rod under the drive of pinion gear group, slide valve is made to return to neutral position, closes to execution
The oil circuit of mechanism, executing agency stop on setting position.
Detailed description of the invention
The mechanical type hydraulic valve schematic diagram of Fig. 1 band feedback
A kind of mechanical type hydraulic valve-operation mechanism of band feedback of Fig. 2
Explanation: 1, handwheel is numbered in figure；2, pinion gear group；3, gear wheel；4, the control-rod with circular cone sleeve gear；5, it rubs
Pad, 6, ear mount, 7 slide valves, 8, rope arrangement 9, executing agency；10, feedback mechanism.
Specific embodiment
As shown in Figure 1, 2, a kind of hydraulic valve mechanical feedback operating mechanism, including executing agency 9, feedback mechanism 10,
Handwheel 1, pinion gear group 2, gear wheel 3, the control-rod 4 with conical sleeve gear shaft, friction plate 5, ear mount 6, slide valve 7, cable wire machine
Structure 8.
Pinion gear group 2 is made of 3 gears, is supported by the connection of bolt and bearing, by pinion gear group 2, control
Bar 4 and gear wheel 3 link together.Ear mount 6 connects pinion gear group 2 and slide valve 7, realizes maneuvering motion.Handwheel 1 passes through spiral shell
Nail is fixed on the control-rod 4 with conical sleeve gear shaft, is furnished with friction plate 5 between the two, for preventing in 10 band of feedback mechanism
When dynamic gear wheel movement, the frictional force between gear will drive the movement of handwheel 1, cause feedback mechanism 10 that can not make during slide valve 7 returns to
Vertical position, oil circuit can not turn off.
When rotating handwheel 1, the 4 rotate driving pinion gear group 2 of control-rod with conical sleeve gear shaft, pinion gear group 2
It pulls ear mount 6 to open pressure oil circuit with movable pulley 7, is that executing agency 9 moves under the action of pressure oil at this time, pinion gear
Group 2 is only slided on gear wheel 3, not will drive the movement of gear wheel 3, is made hand wheel rotating angle by the transmission ratio of gear member and hold
9 angle of row mechanism is directly proportional.
Executing agency 9 is crosslinked by rocker arm and feedback mechanism 10, and feedback mechanism 10 is connected by rope arrangement 8 and gear wheel 3
It connects, while 1 stop motion of handwheel, the position signal of executing agency 9 can be passed through driving rocker arm feedback by 8 moment of rope arrangement
It is transmitted to feedback mechanism 10, drives gear wheel 3 to rotate backward at this time, it is reversed to drive pinion gear group 2 by the feedback of gear wheel 3,
Pinion gear group 2 is rolled in the conical sleeve gear shaft of control-rod, and control-rod 4 remains stationary, and is led under the drive of pinion gear group 2
Pull rod 4 is crossed, 7 lower part slide valve of slide valve is made to return to neutral position, closes the oil circuit for arriving executing agency 9, executing agency 9, which stops at, to be set
Positioning is set.
To guarantee that pinion gear will not reversely drive handwheel 1 while rolling on the circular cone sleeve gear on control-rod 4,
Handwheel 1 is arranged with friction plate 5, and moment of friction is enable to overcome pinion gear roller on the circular cone sleeve gear on control-rod 4
The reverse actuating force of generation guarantees that handwheel 1 is static.
1 rotational angle of handwheel can be arranged with 9 rotational angle of executing agency by system requirements, utilize the biography between gear
Dynamic ratio, the proportionate relationship between realization 1 rotational angle of handwheel and 9 rotational angle of executing agency, and gear wheel is driven by pinion gear,
Realize deceleration.Make 9 smooth motion of executing agency.
