摘要:
A gyroscopic roll stabilizing device for a marine vehicle, comprising a base (1) communicating with an arrangement comprising a rotor (2) rotatable about an axis (6), a motor (3) for rotating the rotor about the axis, a swing container (8) swinging about a swing axis (7) and having the rotor communicating thereto, a first support member (4) and a second support member (5) being opposite to the first support member for swingingly supporting the swing container. The device comprises an actuating means (10) rotating said arrangement about an axis around which the rotor does not swing in its free state.

In a swing motion reducing apparatus for a ship includes a flywheel, a gimbal mechanism configured to rotatably support the flywheel, a motor configured to rotate the flywheel based on a drive power to be supplied; and a motor driver configured to supply the drive power to the motor. A damper section is configured to brake a swing motion of the gimbal mechanism. A safety unit controls the motor driver to stop the supply of the drive power to the motor when a temperature of the damper section is equal to or higher than a predetermined temperature.

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).
摘要:
There is provided a device (10) for orientating a load to be suspended and moved by a crane. The device (10) comprises a flywheel (11) mounted for rotation in a housing (14). A turntable (17) is pivotally connected to the housing (14) and is drivable relative to the housing using a driven worm gear (23) meshing with an annular set of teeth (22) on the turntable (17). The turntable has an axle (18) to which loads can be attached. When the flywheel (11) is spinning at high speed it resists movement out of its plane of rotation so as to stabilise the cable in winds, etc. The flywheel (11) also allows the worm gear to react against it so as to turn the load relative to the flywheel (11). Maneuvering of the load is therefore made easier.
