PROPULSION APPARATUS FOR SHIP, AND SHIP HAVING THE SAME

摘要

PURPOSE: A propulsion device and a ship with the same are provided to install a counter rotating device to a tail end of a hull because the volume of a counter rotating device is reduced by comprising a counter rotating device with multiple bevel gears. CONSTITUTION: A propulsion device for a ship comprises a rear propeller(20), a front propeller(30), and a counter rotating device(70). The rear propeller is fixed on a driving shaft. The front propeller is rotatably supported in the driving shaft. The counter rotating device comprises multiple bevel gears installed in the tail end of a hull. The bevel gears reverse the rotation of the driving shaft and transmit the reversed rotation to the front propeller.
