CONSTITUTION: A propulsion device for a ship comprises a rear propeller(20), a front propeller(30), and a counter rotating device(70). The rear propeller is fixed on a driving shaft. The front propeller is rotatably supported on the driving shaft of the rear propeller. The counter rotating device reverses the rotation of the driving shaft and transmits the reversed rotation to the front propeller. The counter rotating device comprises a driving bevel gear(71), a driven bevel gear(72), multiple counter rotating bevel gears(73), and a clutch device(80). |
