PROPULSION APPARATUS FOR SHIP AND SHIP HAVING THE SAME

摘要

PURPOSE: A propulsion device and a ship with the same are provided to transmit power to a front propeller without using an outer shaft by directly connecting a bevel gear of a reverse rotating device and the front propeller. CONSTITUTION: A propulsion device for a ship comprises a rear propeller(20), a front propeller(30), a reverse rotating device(70), a front thrust bearing(52), a rear thrust bearing(53), a support ring(60), and reinforcing members(41,42). 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 front thrust bearing and the rear thrust bearing transmit thrust generated by the front propeller. The support ring is supported between the rear thrust bearing and the rear propeller. The reinforcing members are arranged in the support ring and the rear propeller.
