The anti-rolling gyroscope has the advantages of no influence of navigational speed on the anti-rolling effect, compact structure, small occupied space, good anti-rolling effect and the like, so the anti-rolling gyroscope is more and more widely applied to the field of ship anti-rolling.

The anti-rolling gyroscope is internally provided with a heavy flywheel, and the flywheel rotating at a high speed has momentum moment and precession physical effect of the gyroscope. The swinging motion of the ship body enables the rotating flywheel to generate precession torque to push the flywheel and the flywheel frame to precess together, meanwhile, the rotating flywheel generates anti-rolling torque during precession, and the anti-rolling torque is transmitted to the ship body through the flywheel frame and the base to inhibit the ship body from swinging.

When the anti-rolling gyroscope works, the flywheel system performs reciprocating precession around the precession axis. The flywheel system is generally provided with an orbiting wire harness for various purposes including power supply, and the orbiting wire harness has one end fixed to the flywheel frame and in a reciprocating swing state with respect to the base, and the other end fixed to the base and in a relatively stationary state. The orbiting wire harness orbits repeatedly with the precession of the flywheel frame, and after long-term use, the internal copper wires of the orbiting wire harness are fatigue-broken due to repeated curling and bending, and the orbiting wire harness needs to be replaced periodically.
