Abstract

The invention relates to a magnetic coupling component and a magnetic coupling steering device thereof, wherein the magnetic coupling component comprises a shell, a front cover and a rear cover whichare both arranged on the two ends of the shell. The shell forms two relative chambers from the intro-radial direction, which are defined as an inner cavity and an external chamber respectively. The inner cavity of the shell is provided with an inputting rotator, wherein the input axis of the inputting rotator extends out the front cover; the external cavity of the shell is provided with an outputting rotator, wherein the output axis of the outputting rotator extends out the rear cover; the inputting rotor and the outputting rotor are respectively embedded with a plurality of magnetic parts ontheir respective relative surfaces. Compared with the prior art, the magnetic coupling component and the magnetic coupling steering device thereof have the advantages that the magnetic induction of the interaction between the inputting and outputting of the rotors is enhanced, which effectively improves the torque when the magnetic coupling steering device drives the outputting rotor to rotate bythe inputting rotor; at the same time, the axial structure of the magnetic coupling component becomes more compact.

Description

Technical field [0001] The invention belongs to the technical field of electromechanical integration, and particularly relates to a magnetic coupling steering device for underwater use. Background technique [0002] At present, most autonomous underwater vehicles use rudders to control the heading and attitude angles. The conventional rudder turning device relies on a contact dynamic seal to transmit the torque in the sealed cavity to the rudder blade outside the sealed cavity to realize the rotation of the rudder blade. In this contact type dynamic seal, the rotating shaft and the stationary seal ring are in contact with and rotate relative to each other with a certain pre-pressure, because the friction between the two is bound to have frictional power loss. In addition, after long working hours, the sealing ring will wear out and there is a risk of water leakage. Because the rudder blade protrudes from the main body of the vehicle, it is easy to damage the rudder steering dev...
