Description
Technical field
The invention belongs to Marine engineering technical fields, and in particular to a kind of propeller for vessels steerage raising device.
Background technology
Marine propeller refers to being rotated in air or water by blade, converts engine rotation power to the dress of propulsive force
Set, can there are two or more leaf be connected with hub, the one side backward of leaf is helicoid or is similar to a kind of of helicoid and peculiar to vessel pushes away
Into device.Currently still using internal combustion engine as ship mainstream power plant under the premise of, the status of propeller is almost unshakable.
However, since the second half in last century, with material science and hydromechanical continuous development, various Novel ship propellers connect
Even come out, though they in propulsive efficiency still not as good as propeller, challenge also is proposed to traditional screw propeller.With
This as the informationization of port traffic, the degree of automation are constantly promoted, also proposes higher want to the maneuverability of ship simultaneously
It asks.In this background, the various screw propellers for pursuing efficient improvement come into being, such as the real ship of equipment in 2004
Co-axial contra rotating propeller CRP and the high skew propeller HSP etc. that is developed for specific demand, wherein being most widely used
It is the adjustable pitch propeller CPP that history can trace back to the twenty or thirty age in last century, operation principle is by changing propeller
The angle of pitch of each blade, makes the angle of attack of blade and flow change, and then realizes the purpose of ship parking or reversing.However
Traditional tuning for Controllable Pitch Propeller is only capable of realizing the equidistant roll adjustment of all blades, though this roll adjustment mode can effectively improve the reversing of ship and stop
Vehicle performance can not but be effectively improved the steerage of ship, and its structure design is cumbersome, and drive connection is complicated, safeguard ten
Divide inconvenience.To solve the above-mentioned problems, a kind of total and fractional distance adjustor is developed, to further increase the steerage of ship.
Invention content
1, technical problem to be solved：
Traditional tuning for Controllable Pitch Propeller is only capable of realizing the equidistant roll adjustment of all blades, though this roll adjustment mode can effectively improve ship
Reversing and stopping performance, can not but be effectively improved the steerage of ship.
2, technical solution：
In order to solve problem above, the present invention provides a kind of propeller for vessels steerages to improve device, including paddle shaft 6 and paddle
Hub 1,6 both ends of the paddle shaft are respectively that host and propeller hub 1 connect, and 6 tail end of paddle shaft is equipped with total and fractional distance adjustor, described total and fractional
Distance adjustor includes blade root bearing disk 2, sliding block 3, push-pull rod 4, connecting key 5, and the push-pull rod 4 is from 6 transition of paddle shaft, one point
It is four, and uses dovetail structure, is connected two-by-two.The sliding block 3 and blade root bearing disk 2 are arranged on push-pull rod 4, the sliding block
3 are connect with blade root bearing disk 2 by connecting key 5, and the sliding block 3 is non-be fastenedly connected with push-pull rod 4 and blade root bearing disk 2.
4 circumferential direction of the push-pull rod is equipped with the conduit slided for sliding block 3.
It is described to be mostly evenly arranged with push-pull rod 4.
3, advantageous effect：
Propeller for vessels steerage provided by the invention, which improves device, can effectively improve the steerage during ship's navigation, structure
Simplicity is flexible, compact in design, and energy utilization rate is high in operational process, can effectively reduce navigation cost, be particularly suitable for medium-and-large-sized
Ship.
Description of the drawings
Fig. 1 is propeller distance adjustor axonometric drawing.
Fig. 2 is propeller distance adjustor sectional view.
Specific implementation mode
Below by attached drawing, the present invention is described in detail.
As shown in Figure 1, a kind of propeller for vessels steerage improves device, including paddle shaft 6 and propeller hub 1,6 both ends of the paddle shaft point
Not Wei host and propeller hub 1 connect, the total and fractional distance adjustor of 6 tail end of paddle shaft, the distance adjustor includes blade root bearing disk 2, sliding block
3, push-pull rod 4, connecting key 5.As shown in Fig. 2, the push-pull rod 4, from 6 transition of paddle shaft, one point is four, and uses dovetail
Structure is connected two-by-two.The sliding block 3 and blade root bearing disk 2 are arranged on push-pull rod 4, and the sliding block 3 is logical with blade root bearing disk 2
The connection of connecting key 5 is crossed, the sliding block 3 is non-be fastenedly connected with push-pull rod 4 and blade root bearing disk 2.
Push-pull rod 4 is can be seen that from the above structure and does longitudinal movement with movable slider 3, generates an axial force, simultaneously because
Constraint of the blade root bearing disk 2 by connecting key 5 to sliding block 3, generates the centripetal force of a circumferential direction, and the synthesis of two power makes described
Sliding block 3 drives blade root bearing to coil its center and circles.
In order to which preferably band movable slider 3 does longitudinal movement to push-pull rod 4,4 circumferential direction of the push-pull rod is equipped with to be slided for sliding block 3
Capable conduit.
It is described to be mostly evenly arranged with push-pull rod 4 for better effect, as long as being stayed to respective sliding block 3 and blade root bearing disk 2
Go out space.
The distance adjustor is not limited in push-pull rod-slide block mechanism, it is also possible to and crank connecting link and other mechanisms replace,
Other joinery and its constructions also can be used in the push-pull rod or non-joinery and its construction is connected, but should retain the movement of its axial single-degree-of-freedom
Ability and total and fractional structure feature.
The operation principle of distance adjustor is under normal circumstances, to drive the distance adjustor and propeller hub 1 to rotate by paddle shaft 6；
When needing to promote steerage, any push-pull rod 4 travels longitudinally with movable slider 3, an axial force is generated, simultaneously because institute
Constraint of the blade root bearing disk 2 by connecting key 5 to sliding block 3 is stated, the centripetal force of a circumferential direction is generated, the synthesis of two power makes the cunning
Block 3 drives blade root bearing to coil its center and circles, and then drives blade rotation.Due to its total and fractional structure feature,
Any push-pull rod 4 and its corresponding sliding block 3 and blade root bearing disk 2 can work independently.Therefore, by controlling above-mentioned roll adjustment machine
Structure, it will be able to so that the angle of pitch of the propeller blade when being threaded to left semicircle is more than angle of pitch when being threaded to right semi-circle, left semicircle
Suck stream and discharge stream are more than right semi-circle, and the discharge stream for flowing to the rudder blade wing back of the body is more than aerofoil, increase the pressure difference that discharge stream is formed,
Make thrust center deviation, generates deflecting effect, realize the promotion of steerage.
Embodiment more than original text is merely illustrative of the invention's technical idea, and the protection model of the present invention cannot be limited with this
It encloses, every any change according to technological thought proposed by the present invention, done on the basis of technical solution each falls within guarantor of the present invention
Within the scope of shield.The technology that the present invention is not directed to can be realized by existing technology.
