More Information
Summary:An oscillation suppression device (11) comprises a base body (12) to be secured to a ship body (10a) a gimbals (13) secured to the base body (12), a damper (14), a flywheel (15) provided in the gimbals (13), and a motor (16) for rotating the flywheel (15), etc. The gimbals (13) is supported by bearings (30, 31) built into a pair of side walls (21, 22) of the base body (12), respectively, such that it can rotate around a first axis (X1). The flywheel (15) can rotate around a second axis (X2). A rotor member (40) of the motor (16) is attached to the flywheel (15), and a stator member (41) is attached to the gimbals (13). The rotor member (40) and stator member (41) are located inside the locus-of-rotation of the gimbals (13). The base body (12) includes a cover portion (23) covering the outer surface of the gimbals (13).
