A forward rotation clutch 31 interposed between and is fitted (clutch “on”) to integrate the forward rotation hollow shaft 24 and the input shaft 23. In this case, since the hollow shaft 25 for reverse rotation is in an idling state together with the bevel gear 27, the driving force from the main engine 7 is the input shaft 23, the hollow shaft 24 for forward rotation, and the bevel gear 2.

After being transmitted to the outer and inner propeller shafts 3 and 4 via 8 and 19, the front propeller 5 and the rear propeller 6 are rotated in opposite directions to generate propulsive force of the ship.

進させることが可能となる。When the propulsive force is generated, the clutch 31 for forward rotation is disengaged (clutch "disengaged"), and then the clutch for reverse rotation is interposed between the hollow shaft 25 for reverse rotation and the input shaft 23. When 32 is fitted, the hollow shaft 24 for normal rotation is in an idling state, and the driving force from the main engine 7 is transmitted to the vertical shaft 20 via the input shaft 23, the bevel gears 27, 28, and the vertical shaft 20. Is reversely rotated, and is further transmitted from the vertical shaft 20 to the propeller shafts 3 and 4 so that the propellers 5 and 6 are rotated in the opposite direction to the above-described direction, so that the ship can be propelled rearward.

に向上させることができる。In this case, since the propellers 5 and 6 can be turned by 90 degrees or more in the left and right sides of the hull, the full propulsive force can be generated even in the lateral direction of the hull. Therefore, if a bow thruster (not shown) is installed on the bow and the bow thruster and the turning propulsion device 1 are used in combination, lateral movement of the ship becomes possible and maneuverability at the time of berthing and berthing in the port is improved. It can be dramatically improved.

Therefore, it is not necessary to provide a thruster, and therefore, the propulsion resistance is reduced and the directional deviation of the propulsion force is eliminated when the boat is traveling straight, and the vibration force generated in the propellers 5 and 6 is reduced. The ship has low vibration and low noise, improving the habitability inside the ship and
The maintainability of various equipment such as the hull and outfitting is improved.

る。As described above, according to the steering apparatus for a ship of the present invention, the propeller pot is fixed to the lower end of the strut which is hung from the stern of the ship and rotatably supported. In addition, the outer propeller shaft with the front propeller fixed to the rear end and the inner propeller shaft with the rear propeller fixed to the rear end are doubly supported so that they can rotate freely. The lower end of the vertical shaft, which is received and rotatably supported, is connected to the outer and inner propeller shafts via a bevel gear, and the propeller is rotated through the input shaft, the vertical shaft, and the propeller shaft to obtain propulsion force. The above propulsion device is equipped with one swivel propulsion device capable of swiveling by rotating the strut by the swivel drive device, and the swivel propulsion device is swung to change the thrust direction. Since it is configured to steer, the course of the ship can be arbitrarily changed by changing the direction of the fixed propeller, thus rudder is unnecessary and the propulsion resistance of the ship is reduced and the ship goes straight. In this case, the directional deviation of the propulsion force of the ship does not occur, so the ship maneuvering performance can be improved without impairing the propulsion performance of the ship, and the counter-rotating propeller device is used. As a result, the propulsion performance of the ship can be significantly improved, which is an excellent effect.

たことを特徴とする船舶の操舵装置。1. An upper end portion of one strut that hangs down from a position on a center line of the hull and has a propeller pot fixed to a lower end thereof is rotatably supported on the hull, and a strut drive device installed in the hull allows the strut to move. A vertical shaft, which is rotatable and has an input shaft rotatably supported in the hull, is adapted to be rotated by receiving power from the input shaft and rotatably supported inside the strut. Further, in the propeller pot, a propeller shaft having a propeller fixed to the rear end is rotatably supported, and the lower end of the vertical shaft is connected to the propeller shaft so as to transmit the rotational force of the vertical shaft to the propeller shaft. , The power from the input shaft is transmitted to the vertical shaft to rotate the propeller to generate propulsive force, and the turning drive device rotates the strut to horizontally rotate the propeller. A steering apparatus for a ship, comprising a turning propulsion device having a contra-rotating propeller configured to be steered, and the turning propulsion device being connected to a main engine mounted in one hull.
