Abstract
PURPOSE: To provide a method of the reduction of vibration of a twin-screw vessel, wherein right and left propellers of the twin-screw each having four blades which have a relationship rotated by 45° with respect to the other four blades are arranged, and respective propeller shafts are rotated keeping their prescribed positional relationship each other through driving gear means etc., so that the vibration of the twin-screw vessel will be reduced.
CONSTITUTION: Propeller shafts 4a, 4b of propellers 6a, 6b are rotated by main machines 2a, 2b, through reduction gears 3a, 3b. Four rotary blades 5a of the propeller 6a have a relationship rotated by 45° with respect four rotary blades 5b of the propellers 6b. The blades 5a, 5b are coactively rotated by the respective propeller shafts 4a, 4b through a driving gear means 7, so that the vibrations resulting from the rotation of the respective propellers 6a, 6b will negate each other to reduce the vibrations generally.
