Planar precession type ship gyro stabilizer

Abstract

The invention relates to ship equipment, in particular to innovations of a framework and a component in a stabilization gyro for a ship. The ship gyro stabilizer brings forth new ideas in the framework of a ship stabilizer, and adopts a planar rotary disc bearing component. A rotor shaft is selected to be arranged horizontally, the mass and the load of a rotor are borne by two bearings which are arranged in the horizontal direction, the axial load of the bearings is eliminated, and the bearing capability of the bearings is improved, meanwhile, the structure of a support supporting the bearings is changed from a static loading suspension arm stress structure into a compression rod supporting structure, and the bearing capability of the support is improved obviously. A frame shaft is arranged vertically, a planar rotary disc bearing is selected, because the bearing capacity arm is increased by several to dozens of times, the borne bending moment of the planar rotary disc bearing is improved greatly, and the bending moment borne by the bearings is rightly the stabilizing moment transmitted by the planar rotary disc bearing and output to a ship. Based on the innovations, it is possible that the large stabilizing moment is transmitted and borne in a stabilization gyro device mechanism, and the practical application of a stabilization gyro device for a large-size ship can be achieved.

Description

technical field [0001] The invention relates to ship equipment, in particular to innovations in the technical level of large-scale ship anti-rolling gyro. Background technique [0002] The marine anti-rolling gyro is a kind of ship anti-rolling device. Its biggest feature is that it not only has a high anti-rolling effect, but also can stabilize the roll at zero speed. Small marine anti-rolling gyro has been used on ships such as small yachts. Its characteristic is that the momentum moment generated by the rotor is small, and the righting moment generated is not large, so it cannot be applied to large ships. The working principle of the anti-rolling gyro is to rely on the high-speed rotating rotor to generate the rotor momentum moment, and generate the righting moment through the change of the momentum moment vector to restrain the ship from swaying. The marine anti-rolling gyro is mainly composed of a rotor, a frame, and a base. The rotor is installed in the frame, and the...

AI Technical Summary

Problems solved by technology

The moment of momentum of a large anti-rolling gyro rotor is as high as several hundred kN·m·s , the mass of the rotor is several tons to more than ten tons, the rotor shaft and bearing, the frame shaft and the bearing need to carry huge load force and impact, the traditional ship anti-rolling gyro structure, the bearing cannot bear the load

Due to the above reasons, the marine anti-rolling gyro cannot develop in the direction of large-scale
