<p>PURPOSE: A propulsion device and a ship with the same are provided to reversely rotate two propellers without an outer shaft and to measure the operation state of a counter rotating device. CONSTITUTION: A propulsion device for a ship comprises a rear propeller, a front propeller, a counter rotating device(70), a flange part, and at least one sensor(211,212). The rear propeller is fixed in a driving shaft. The front propeller is rotatably supported on the exterior of the driving shaft. The counter rotating device is installed in the tail end of a hull, reverses the rotation of the driving shaft, and transfers the reversed rotation to the front propeller. The flange part is installed in the driving shaft and supports the counter rotating device. The sensor measures the movement of the flange part.</p> |
