PROPULSION APPARATUS FOR SHIP, AND SHIP HAVING THE SAME

摘要

PURPOSE: A propulsion device and a ship with the same are provided to accurately maintain a gap between a reverse bevel gear and a driven bevel gear by installing a gap adjusting member between the driven bevel gear and a front propeller hub. 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 in the driving shaft. The reverse rotating device reverses the rotation of the driving shaft and transmits the reversed rotation to the front propeller. The reverse rotating device comprises a driving bevel gear, a driven bevel gear, and at least one reverse bevel gear. A gap adjusting member is installed between the driven bevel gear and a front propeller hub.
