FIELD: engines and pumps.SUBSTANCE: invention relates to ship building and can be used in structures of ship propellers. A propulsion-steering column includes a column base, a spindle, a drive shaft that is located inside the spindle, a column turning mechanism, an angular gearbox, a streamlined nacelle fixed on the spindle and closing the angular gearbox. A screw propeller and a screw shaft are located inside the housing of the nacelle that adjoins the hub of the screw propeller and transmits torque moment to it. The hub is installed through bearings on the nacelle housing and provided with an end transmitting element. The transmitting element is attached both to the hub of the screw propeller and to the screw shaft.EFFECT: improving operating reliability of a propulsion-steering column and simplifying replacement of a screw shaft.4 cl, 2 dwg |
