Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Attached drawing 1 to 5 is please referred to, the utility model embodiment includes:
A kind of non-contact transmission indicating mechanism for ship pitch tuning for Controllable Pitch Propeller feedback, as depicted in figs. 1 and 2, feedback
Ring 1 is installed in tuning for Controllable Pitch Propeller shafting, is rigidly connected with axially moveable member inside shafting, and tuning for Controllable Pitch Propeller is adjusted during the work time
When screw pitch, feedback loop follows shafting to be rotated, while the axial movement component inside shafting being followed to make axis direction
Translational motion.
Erection support 10 is fixed on ship hull plate by bolt 15 by non-contact transmission indicating mechanism, and when installation ensures paddle
Leaf screw pitch is in vertical position, adjusts the position of erection support 10, guarantees in the widthwise central face of crank 4 and the thickness of feedback loop 1
Heart face is in approximately the same plane, and installation site at this time is as shown in Figure 3.
Scale plate 11 and fixing seat 8 are installed, scale plate 11 is fixed on installation branch by the first screw 9 on erection support 10
On seat 10, fixing seat 8 is by being fixedly welded on erection support 10.Potentiometric sensor 14, potentiometric sensors are installed in fixing seat 8
Device 14 is mounted in fixing seat 8 by the second screw 7.8 inner hole of fixing seat is equipped with two bearings, to support current potential to pass
The long mandrel that sensor 14 stretches out.Pointer 12 and crank 4 are installed on the long mandrel of potentiometric sensor 14, pass through third screw respectively
13 and the 4th screw 5 it is fixed, one end of crank 4 is equipped with magnet 2, and magnet 2 is fixed on one end of crank by the 5th screw 3.
The relative mounting location that adjustment pointer 12 and crank 4 are needed before fixed third screw 13 and the 4th screw 5, makes crank 4 and feedback
Ring 1 is concordant and magnet 2 and feedback loop 1 between there are suitable gap S, then the 4th screw 5 is locked, keep crank 4 with
The indicating positions of pointer 12 is allocated at vertical scale line by the flush position of feedback loop 1, finally fixes third screw 13.Generally
The state of hanging corresponds to the scale state at blade vertical pitch angle on scale plate to crank vertically.
When tuning for Controllable Pitch Propeller carries out positive vehicle roll adjustment, feedback loop 1 is rotated simultaneously and translational motion to the left, such as Fig. 4
It is shown.Due to there is attraction F effect between feedback loop 1 and magnet 2 always, when feedback loop 1 is carried out to left, attraction
F will generate therebetween a horizontal component F', and component F' makes magnet 2 that feedback loop 1 be followed to be moved downward together,
Because magnet 2 is fixed on crank 4, therefore magnet 2 drives crank 4 to rotate, while the mandrel of potentiometric sensor 14 being driven to turn
It is dynamic, it is connected with a potentiometer in the other end of mandrel, potentiometer is defeated with corresponding current or voltage signal by the angle of rotation
Out to electric-control system as the display signal of screw pitch and the feedback signal of pitch.The pointer 12 installed on mandrel equally follows core
Axis rotation, the corresponding reading of scale plate 11 are then the mechanical pitch show value of tuning for Controllable Pitch Propeller.
When tuning for Controllable Pitch Propeller carries out reversing roll adjustment, feedback loop 1 is rotated simultaneously and translational motion to the right, such as Fig. 5
It is shown.Due to there is attraction F effect between feedback loop 1 and magnet 2 always, when feedback loop 1 is carried out to when right translation, attraction
F will generate therebetween a horizontal component F', and component F' makes magnet 2 that feedback loop 1 be followed to be moved right together,
Because magnet 2 is fixed on crank 4, therefore magnet 2 drives crank 4 to rotate, while the mandrel of potentiometric sensor 14 being driven to turn
It is dynamic, it is connected with a potentiometer in the other end of mandrel, potentiometer is defeated with corresponding current or voltage signal by the angle of rotation
Out to electric-control system as the display signal of screw pitch and the feedback signal of pitch.The pointer 12 installed on mandrel equally follows core
Axis rotation, the corresponding reading of scale plate 11 are then the mechanical pitch show value of tuning for Controllable Pitch Propeller.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases
The technical field of pass, is also included in the patent protection scope of the utility model.
