<p>PURPOSE: A propulsion device and a ship with the same are provided to install a reverse rotating device in the tail end of a hull by reducing the volume of the reverse rotating device composed of multiple bevel gears. 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. The front propeller is rotatably supported on the driving shaft. 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, a driven bevel gear, a reverse bevel gear, and a moving device. The driving bevel gear is fixed in the driving shaft. The driven bevel gear is connected to the front propeller. The reverse bevel gear reverses the rotation of the driving bevel gear and transfers the reversed rotation to the driven bevel gear. The moving device moves the reverse bevel gear.</p> |
