Abstract

The invention belongs to the technical field of ship stabilization, and particularly discloses an anti-rolling gyro. The anti-rolling gyro comprises a base, a flywheel frame rotationally connected with the base and a flywheel rotationally connected with the flywheel frame, and is characterized by further comprising a torque applying device used for applying braking torque to the flywheel frame. The torque applying device comprises: a permanent magnet synchronous motor, wherein a motor shaft of the permanent magnet synchronous motor is coaxially connected with a precession shaft of the flywheelframe; a resistive load, wherein the winding outgoing line of the permanent magnet synchronous motor is electrically connected with the resistive load to form an energy consumption brake circuit; anda controller electrically connected with the resistive load, wherein the controller is configured to adjust the resistance value of the resistive load so as to adjust the magnitude of the braking torque. According to the stabilization gyro and a ship, the cost of the anti-rolling gyro can be reduced, the safety and reliability of the anti-rolling gyro are improved, and the seaworthiness and passenger comfort in the ship navigation process are improved.

Description

technical field [0001] The invention relates to the technical field of ship anti-rolling, in particular to an anti-rolling gyroscope. Background technique [0002] The anti-rolling gyro has the advantages of anti-rolling effect not affected by the speed of the ship, compact structure, small space occupation, good anti-rolling effect, etc., so it is more and more widely used in the field of ship anti-rolling. [0003] A heavy-duty flywheel is installed inside the anti-rolling gyro, and the high-speed rotating flywheel has the momentum moment and the precession physical effect of the gyro. The rocking motion of the hull causes the rotating flywheel to generate a precessive moment, pushing the flywheel and the flywheel frame to precess together. At the same time, the rotating flywheel generates an anti-rolling moment during precession, and the anti-rolling moment is transmitted to the hull through the flywheel frame and base up, to restrain the swaying of the hull. [0004] T...
