Abstract
PURPOSE: To reduce the vibration of a upper structure due to the unbalanced moment of a main engine and make the size of a vibration eliminator compact while reducing the weight of a hull, consumed power, etc., by installing the vibration eliminator on the upper structure on the hull.
CONSTITUTION: As for a ship with a Diesel engine as a main engine, a vibration eliminator is mounted on the hull of the ship. Two flywheels 4 of the vibration eliminator, which are fitted with counterweights 3, are rotated in the opposite direction to each other by the rotation of a small gear mounted on a driving shaft to reduce the vibration of the hull. The vibration eliminator is installed in the vicinity of the steering house of the superstructure 2 which is usually used as a living quarters, while in the conventional construction, the eliminator has been disposed at the front or rear of the main engine or near the stern. This disposition results in directly reducing the vibration of the superstructure 2 being generated due to the unbalanced moment Mv of the main engine 1.
