Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further.
Fig. 1 is the three-dimensional modeling schematic diagram of rudder ball counter rotating propeller of the present invention.As shown in Figure 1, whole rudder ball counter rotating propeller system is made up of main screw 1 (containing blade and propeller hub) and spinner 2, auxiliary screw propeller 3, rudder ball 4 and rudder body 5.The line of centers of rudder ball 4 overlaps with the axial line of main screw 1, and auxiliary screw propeller 3 is positioned on rudder ball 4.Main screw 1 is driven by marine main engine, and auxiliary screw propeller 3 is driven by the small-sized integrate motor be built in rudder, is combined to form turning form with main screw 1.
Rudder ball 4 is oval gyro-rotor, is arranged on the front of rudder body 5, and just to main screw 1 Jiang Zhou center, the diameter of rudder ball 4 is about 0.8 ~ 1.5 times of main screw 1 propeller hub small end face diameter.Auxiliary screw propeller 3 is positioned on rudder ball 4, and its diameter is about 0.2 ~ 0.5 times of main screw 1 diameter, is driven by built-in small-sized integrate motor, contrary with main screw 1 rotation direction, its number of sheets can identical from main screw 1 also can be different.
The principle of work of rudder ball counter rotating propeller of the present invention is as follows:
After main screw 1 installs spinner 2, strong hub whirlpool can be formed at spinner 2 rear, after rudder body 5 is installed rudder ball 4, hub whirlpool can be broken up, absorb hub whirlpool energy, the surface pressure of spinner 2 is restored, and the overall thrust of such main screw 1 and spinner 2 is increased, thus improves propulsion coefficient.It is more suitable that the diameter of rudder ball 4 is about 0.8 ~ 1.5 times of main screw 1 propeller hub small end face diameter, the distance dependent of its key role parameter and main screw or spinner, general distance is more near better, and distance restriction is mainly considered for actual installation technique, should facilitate the dismounting of main screw 1 and spinner 2.
When main screw 1 works, except producing hub whirlpool, the current of whole wake zone all can produce the rotative speed of circumference, after rudder ball 4 is installed auxiliary screw propeller 3, auxiliary screw propeller 3 is driven by built-in integrate motor, and its rotation direction is contrary with main screw 1, jointly forms a kind of novel to turning oar system with main screw 1, the loss of main oar wake flow rotating energy can be absorbed, thus improve the efficiency of whole propulsion system.It is more suitable, unsuitable excessive that the diameter of auxiliary screw propeller 3 is about 0.2 ~ 0.5 times of main screw 1, and diameter is about large, and weight is also larger, thus makes the stress that the generation of the junction of rudder ball 4 and rudder body 5 is larger, occurs structural strength problem.Auxiliary screw propeller 3 diameter is larger in addition, and the power of built-in integrate motor and volume are corresponding also larger, will increase whole rudder ball to the technical risk turning oar system.The rotation direction of auxiliary screw propeller 3 should be contrary with main screw 1, and the number of sheets and main screw 1 are quite (identical or be the number of sheets ± 1 of main screw 1).
In ship turning manipulation process, auxiliary screw propeller 3, rudder ball 4 and rudder body 5 integrally unit rotate with rudderpost, and the thrust of now auxiliary screw propeller 3 generation, contributes to turning to of whole boats and ships, thus reduce boats and ships radius of turn, improve ship maneuverability.
