A vessel use ring key and propeller propulsion installation is provided to rapidly steer a ship by increasing a thrust through guiding water in a direction to support a ring key and a propeller. A vessel use ring key and propeller propulsion installation includes a rotation shaft(26) vertically installed in a vessel to be rotated in forward and reverse directions, and the ring key(25) to support a propeller(23) to the rotation shaft and a driving unit(20) using several supports(24). The ring key supported by rotation shaft and the several supports are configured to forwardly and reversely rotate the driving unit. A steering device includes the rotation shaft and the ring key, supported by the several supports, a gear(12) of the rotation shaft installed to a flange(11), and a motor(14) having a pinion(13) installed to the flange. The steering device includes bevel gears(21,22) to perpendicularly connect the horizontal propeller of the driving unit to a driving shaft(15). A pipe-shaped rotation shaft selectively rotates the ring key forwardly and reversely. |
