Description

technical field [0001] The invention relates to the technical field of underwater transmission and observation platforms, in particular to a full-sea deep magnetic coupling transmission motor and a full-sea two-dimensional cloud platform. Background technique [0002] The full-sea depth camera is one of the most effective means for underwater observation to obtain intuitive visual images. Affected by the unevenness of the deep-sea landform, the field of view of the fixed-installed full-sea depth camera often depends on the landing attitude of the carrying platform. There is often a phenomenon that the camera's field of view cannot cover the target area, which affects the effect and purpose of observation. Therefore, there is an underwater two-dimensional two-degree-of-freedom gimbal suitable for the full sea depth. Through the rotation of the gimbal itself in two dimensions, it realizes the three-dimensional observation of the ocean environment with a camera, which effective...

Problems solved by technology

[0006] (1) If it is used in the marine environment for a long time, its dynamic sealing ring is prone to fatigue wear and corrosion aging, resulting in leakage of the oil-filled sealed cabin and transmission failure;

[0007] (2) With the increase of the diving depth, the oil pressure in the oil-filled sealed cabin increases, and the density and viscosity of the oil also increase, resulting in an increase in the viscous resistance between the motor rotors, and the radial extrusion between the sealing ring and the output shaft The existence of friction, the total output efficiency of the motor decreases, the power consumption increases, and the noise is very loud;

[0008] (3) In addition to increasing with the depth, the viscous resistance is also proportional to the relative speed between the motor rotors. The higher the speed, the greater the viscous resistance, which makes the response speed of the underwater gimbal mechanism slower
