Fall into:
1, the connected mode of sliding sleeve, in use, has the feedback air working days so that feedback
Precision seriously lags behind actual act；
2, the connected mode of sliding sleeve, will control fit clearance accurately, and fit clearance is excessive
Feedback accuracy will be affected；Fit clearance is too small, can increase the resistance of mechanism kinematic.
Summary of the invention
In order to overcome existing box type oil distributor feedback mechanism to there is feedback signal less stable
Defect, this utility model provides a kind of feedback signal stability preferable box type oil distributor feedback
Mechanism.
This utility model solves its technical problem and be the technical scheme is that
A kind of box type oil distributor feedback mechanism, described feedback mechanism includes chain, sprocket wheel and master
Driving wheel rotating shaft, described sprocket wheel includes that drive sprocket and driven sprocket, described driven sprocket pass through chain
Bar is connected with described drive sprocket, and described driven sprocket is arranged in driven pulley rotating shaft, described master
Movable sprocket is arranged in described drivewheel rotating shaft, and chain, sprocket wheel, oil distribution mechanism are respectively positioned on joins oil
In device casing；
Described drivewheel rotating shaft is rotating to be arranged on oil distributor casing, described drivewheel rotating shaft
One end through oil distributor casing with in order to indicate the mechanical indicator of the real-time angle of pitch to be connected, described

The rotary encoder of the angle signal of rotation oar blade connects, described rotary encoder and electric-control system
Connecting, oil distribution mechanism is connected by connecting plate and described chain are fixing.
The beneficial effects of the utility model are mainly manifested in: use sprocket wheel to connect the cunning before changing
The mode that set connects, the stability making the mechanical signal that feedback mechanism feeds back is higher；Additionally
For setting angle, chain sprocket structure is more easily adjusted and installs, and gives and subtracts during using later
Maintenance times and maintenance cost are lacked.
Accompanying drawing explanation
Fig. 1 is the section of structure of box type oil distributor.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the right view of Fig. 2.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
With reference to Fig. 1～Fig. 3, a kind of box type oil distributor feedback mechanism, described feedback mechanism includes
Chain 8, sprocket wheel and drivewheel rotating shaft 1, described sprocket wheel includes drive sprocket 2 and driven sprocket 7,
Described driven sprocket 7 is connected with described drive sprocket 2 by chain 8, described driven sprocket 7
Being arranged in driven pulley rotating shaft 6, described drive sprocket 2 is arranged in described drivewheel rotating shaft 1,
Chain 8, sprocket wheel, oil distribution mechanism 4 are respectively positioned in oil distributor casing；
Described drivewheel rotating shaft 1 is rotating to be arranged on oil distributor casing, described active round
One end of axle 1 through oil distributor casing with in order to indicate the mechanical indicator of the real-time angle of pitch to be connected,
The other end of described drivewheel rotating shaft 1 through oil distributor casing with in order to circular-rotation signal is turned
The rotary encoder 5 of the angle signal turning to propeller blade connects, described rotary encoder 5
Being connected with electric-control system, oil distribution mechanism is connected by connecting plate 3 is fixing with described chain 8.
In the present embodiment, oil distributor casing having graduated tile, show the angle of pitch, mechanical indicator is
For indicating real-time thread pitch to change；Connecting plate 3 is bolted on oil distribution mechanism 4
On, in oil distributor casing, double tube is connected in oil distribution mechanism 4, and double tube is with axle system
Rotating, this axle system is the axle driving propeller；I.e. connect main frame and the axle of propeller, use
Oil distribution mechanism 4 joins oil to double tube, solves to a difficult problem for rotary part fuel feeding, double tube with
Piston connects, and when hydraulic power unit work fuel feeding, promotion piston is moved by hydraulic oil, changes spiral shell
The angle of rotation oar blade, meanwhile drives double tube to move forward and backward in the lump, and we will feed back machine
Structure links together with oil distribution mechanism, thus ensure that what feedback mechanism 13 feedback signal originated asks
Topic.
Double tube includes oil inlet pipe and flowline, and the oil cylinder of oil distributor is divided into two parts by piston,
Two parts are connected with hydraulic power unit by turnover oil pipe respectively, and hydraulic power unit provides hydraulic oil,
When changing the volume of piston side, other side fluid reduces relatively, and returns to main fuel tank, lives
Plug moves；Piston is connected with saddle, and saddle is by slider-crank mechanism and adjustable propeller blade
Connecting, when piston moves, adjustable propeller blade rotates, therewith angle change.
Black box 11 plays sealing function, outside preventing the fluid in box assembly 12 to be leaked to
Limit, box assembly 12 is whole casing, plays support, interconnection function；Oil distribution mechanism 4 be to
The structure of delivering oil in the oil pipe rotated, feedback mechanism 13 is arranged in oil distribution mechanism 4, for
Whole system provides feedback signal.
Between oil distribution mechanism 4 and feedback mechanism 13, we use at connecting plate 3 and chain 8
Between squeeze into pin and fix, thus avoid feeding back neutral, chain 8 and sprocket wheel in feedback procedure
Connection also use tight fit, it is to avoid the neutral phase in feedback procedure, it is provided that the precision of feedback and
Stability.
Drive sprocket 2 is arranged in drivewheel rotating shaft 1, extend out to outside oil distributor casing always
Portion, the other end of drivewheel rotating shaft 1 connects rotary encoder 5, directly moving circular-rotation
It is converted into the angle signal of propeller blade, on display operation screen in electric-control system, makes
Operation shows the most intuitively in face of operator, allows and operates the simple, directly perceived, rapid of change.
Operation principle of the present utility model is:
Feedback mechanism 13 is mainly moved forward and backward by oil distribution mechanism 4 conduction chain, and chain 8 connects
Two sprocket wheels, movable signal, by drivewheel rotating shaft 1, is spread out of outside casing by drive sprocket 2；
Conversion process is, paper slip, by chain 8, is moved the circumference changing into sprocket wheel by oil distribution mechanism 4
Rotating, circular-rotation is passed to by drivewheel rotating shaft 1 and is arranged on oil distributor case by drive sprocket 2
The rotary encoder 5 of external body, circular-rotation signal is converted into propeller by rotary encoder 5
The angle signal of blade, shows in operation screen.
This utility model substantially increases the precision of the data feedback of feedback mechanism, allows feedback mechanism
Become simple, be easily installed and safeguard；While structure is optimized, greatly reduce life
Product cost, cost performance are higher；This mechanism is not limited by vessel power size, can be all kinds of
Applied on a large scale on power boats and ships.
