Gyroscope, support device, anti-roll stabilizer, vessel, use of a gyroscope, and method of servicing or maintaining a gyroscope

A gyroscope for an anti-roll stabilizer for seacraft, comprising:

• a container configured to be mounted on a suspension so as to be able to oscillate around a first axis;
• a flywheel, inside said container, the flywheel having a shaft configured to rotate around a second axis, transverse with respect to said first axis, said shaft of said flywheel having a first end and a second end;
• a first support device, placed inside said container, configured to support said first end of said shaft to allow the relative rotation of said shaft with respect to said container;
• a second support device, placed inside said container, configured to support said second end of said shaft to allow the relative rotation of said shaft with respect to said container;
• an electric motor inside said container configured for rotating said shaft of said flywheel,
• wherein said container comprises a base portion configured to be mounted on the suspension, the base portion comprising a first end portion, as an upper end portion, which is connected removably to said base portion, and a second end portion, as a lower end portion, which is connected removably to said base portion;
• and
• wherein said first support device comprises,
• a first first support device element removably connected to the first end of the shaft of the flywheel of the gyroscope;
• and
• a second first support device element, coaxial to said first first support element, connected removably to the container of the gyroscope,
• wherein said first first support device element is rotatable with respect to said second first support device element, wherein said first and second elements of said first support device are connected one to the other by at least one rolling bearing;
• wherein said second support device comprises a first second support device element connected removably to said second end of said shaft and a second second support device element, coaxial to said first second support device element, which is connected removably to said container, said first second support device element being rotatable with respect to said second second support device element, said first and second elements of said second support device being connected one to the other by at least one rolling bearing;
• and
• wherein the respective first support elements of the respective first and second support devices configured to support said shaft comprise a first bush for accommodating the respective end of said shaft of the gyroscope, said first bush being coupled with interference with said at least one rolling bearing.
