摘要

PURPOSE: A propulsion device and a ship with the same are provided to improve propulsion efficiency and to reversely rotate two propellers without an outer shaft.;CONSTITUTION: A propulsion device for a ship comprises a rear propeller(20), a front propeller(30), a reverse rotating device(70), a motor(131), and a housing(130). The rear propeller is fixed in a driving shaft. The front propeller is rotatably supported in the driving shaft in front of the rear propeller. The reverse rotating device reversely rotates the driving shaft and transfers the reversed rotation to the front propeller. The motor rotates the driving shaft. The housing is extended downward from the tail end of a hull to surround the reverse rotating device and the motor.;COPYRIGHT KIPO 2013
