Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as Figure 1-6 As shown, a multi-directional vector thruster includes a frame 1, a propulsion mechanism 2 and a rotating device 3; the rotating device 3 drives the propulsion mechanism 2 to rotate. The frame 1 is provided with a tripod bracket 11 for shortening the moment arm. The frame 1 can be better fixed by setting the tripod bracket 11, and the tripod bracket 11 can reduce the moment concentrated on the frame at the same time, so the tripod bracket 11 solves the stress concentration problem of the propulsion mechanism 2 well.

[0023] The rotating device 3 includes a first drive motor mount 31 , a first drive motor 32 , a follower 33 and a bearing mechanism 34 ; the first drive motor mount 31 is connected to the frame 1 through bolts. The first driving motor mounting base 31 is provided with a connecting slot 311 fo...

Abstract

The invention discloses a multi-direction vector propeller. The multi-direction vector propeller comprises a rack, a propulsion mechanism and a rotating device; the rotating device drives the propulsion mechanism to rotate; and the rotating device comprises a first driving motor mounting seat, a first driving motor, a driven piece and a bearing mechanism. According to the multi-direction vector propeller, a supporting part matched with the lower end of the first driving motor is arranged on the inner wall of the first driving motor mounting seat, so that the first driving motor mounting seat can better support the first driving motor, the vibration during working of the first driving motor is reduced, and the stability of the first driving motor is improved; a gap is formed between a mounting table and the inner wall of the first driving motor mounting seat, so that the upper end of the first driving motor is not in direct contact with the inner wall of the first driving motor mountingseat, and the efficiency of driving an optical axis to rotate by the first driving motor is improved; by arranging a gap between a second driven piece and a driven piece mounting groove; and the efficiency of driving the optical axis of the first driving motor to rotate is further improved.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a multi-directional vector thruster. Background technique [0002] With the development of navigation, ships, submarines, underwater robots and other equipment are more and more widely used. However, vector propulsion technology is always a difficult technology for these equipment. At present, ships, submarines, AUVs (untethered underwater vehicles) and other equipment mostly use propellers as propulsion devices. The rotation of the propeller causes the water flow to rotate backwards. Only the velocity component parallel to the direction of the propeller axis can produce effective thrust for the underwater vehicle. It has the advantages of large expansion angle of water flow, entrainment and mixing The mixing ability is very strong, and it has weak characteristics such as the recirculation zone, which greatly reduces its propulsion efficiency. Thrust vectoring is...
