PURPOSE: A propulsion device for a ship and an apparatus and a method for installing the same are provided to install a reverse rotating device in the tail end of a hull because the reverse rotating device is composed of multiple bevel gears to reduce the volume thereof. CONSTITUTION: A propulsion device for a ship comprises a rear propeller(20), a front propeller(30), and a reverse rotating device(70). The rear propeller is fixed in a driving shaft(10). The front propeller is rotatably supported on the driving shaft in front of the rear propeller. The reverse rotating device is installed in the tail end of a hull. The reverse rotating device reverses the rotation of the driving shaft and transfers the reversed rotation to the front propeller. The reverse rotating device comprises a driving bevel gear(71), a driven bevel gear(72), a reverse bevel gear(73), and a casing(75). The reverse bevel gear, the driven bevel gear, and the case mutually assembled each other are installed in an installation space arranged in the tail end of a hull. |
