Azimuth thruster for use in ships.

摘要

The azimuth thruster includes: an outboard housing (26) mounted within a substantially conical recess (17) to turn about a vertically axis, the conical recess formed in the bottom of a hull of the ship to converge upwards; a turning unit (23), mounted to the hull, for turning the outboard housing about the vertical axis; a propeller shaft rotatably supported by the outboard housing to cross the vertical axis of the outboard housing with an acute angle ( alpha ); a propeller (42) mounted on the lower end of the propeller shaft to be located outside the outboard housing and within the conical recess and to provide a thrust upwards in the direction of the propeller shaft; and a propulsion unit (52) for rotating the propeller shaft.
