Embodiment 1

[0020] The universal propeller, as shown in the figure, includes a housing 2 and a propeller 1 installed on the housing 2. A joint bearing 3 is installed in the housing 2. The propeller 1 is installed on the spherical inner ring 31 of the joint bearing 3. The spherical surface Two push guide rods 4 are installed on the inner ring 31, and the push guide rod 4 is connected with a push motor 5, and the axial displacement of the push guide rod 4 is realized by the push motor 5, and the joint bearing 3 is driven by the push of the push guide rod 4. Propeller 1 swings.

[0021] Promoting guide rod 4 comprises horizontal push rod 41 and vertical push rod 42, and the angle between horizontal push rod 41 and vertical push rod 42 is 90 ° and controls the left and right swing and up and down swing of spherical inner ring 31 respectively, promotes motor 5 A horizontal motor 51 connected with the horizontal push rod 41 and a vertical motor 52 connected with the vertical push rod 42 are inc...

Abstract

The invention relates to the field of thrusters and discloses a universal thruster. The universal thruster comprises a shell (2) and a propeller (1). A joint bearing (3) is installed in the shell (2), the propeller (1) is installed on a spherical inner ring (31) of the joint bearing (3), a pushing guide rod (4) is installed on the spherical inner ring (31) and connected with a pushing motor (5), and the joint bearing (3) drives the propeller (1) to swing under the pushing function of the pushing guide rod (4). Steering of the universal thruster does not depend on steerage generated when water flow flows past a control surface but depends on vector thrust force which is more direct, so the steering radius is very small, and high steering torque can be generated even under a dead slow condition. The universal thruster has the advantage of being high in steerage and is particularly suitable for military unmanned underwater vehicles.

Description

technical field [0001] The invention relates to the field of propellers, in particular to universal propellers. Background technique [0002] Thrusters (boosters) are generally used to provide power and increase speed. It is widely used in aerospace, shipbuilding, automobile and other fields. It generates thrust by rotating blades or jets of air (water). The traditional propulsion and control system is large in size, complex in structure, and inefficient. Especially at low speeds, the rudder effect is very poor, which is precisely the most common working state of military aircraft; in addition, due to its large size and complex structure, it is easy to cause Blocked and interfered by obstacles and cause the failure of the entire system. Contents of the invention [0003] The invention provides a universal propeller aiming at the shortcomings of large volume, complex structure and low efficiency in the prior art. [0004] In order to solve the above technical problems, ...
