PROPULSION-STEERING COLUMN

FIELD: shipbuilding.SUBSTANCE: invention relates to the field of shipbuilding, namely to the construction of propulsion-steering columns. Propulsion-steering column contains a full-turn water-flow gondola of a cylindrical structure mounted on the bottom of the vessel by means of a vertically installed hollow barrel, two propulsion motors and two propellers. Gondola has a through internal hole, made along and located horizontally. Each of the two propellers is structurally constructed on a large diameter hub on the outer surface of which are numerous propeller blades. Propellers with hubs are located on the outer cylindrical surfaces of the nacelle symmetrically with respect to the vertically installed hollow barrel, and the propulsion motors are made inverted and without a frame, located between the outer part of the gondola and the inner part of the propeller hub. Magnetic line of the stator, each of the propulsion motors is fixed from the outside of the gondola. Stator winding of each propulsion motor is embedded in the grooves of the stator magnetic core and is filled with a compound, which together with the teeth of the stator magnetic core forms an even cylindrical surface. Active part of each rotor of propulsion motors is fixed on the inner surface of the propeller hub. Thrust from the propellers to the gondola is transmitted through bearings located on both sides relative to the stator magnetic circuit of each of the propulsion motors, lubrication and cooling of rubbing surfaces and motor parts subjected to heating are provided with a self-flow through them of the surrounding seawater.EFFECT: achieved in expanding the functionality, reducing the weight and dimensions of the propulsion-steering column, as well as in improving the reliability and survivability of the entire propulsion-steering complex.4 cl, 9 dwg Изобретение относится к области судостроения, а именно к конструкциям движительно-рулевых колонок. Движительно-рулевая колонка содержит полноповоротную водообтекаемую гондолу цилиндрической конструкции, установленную на днище судна посредством вертикально установленного полого ствола, два гребных электродвигателя и два гребных винта. Гондола имеет сквозное внутреннее отверстие, выполненное вдоль и расположенное горизонтально. Каждый из двух гребных винтов конструктивно выполнен на ступице большого диаметра, на внешней поверхности которой расположены многочисленные лопасти гребного винта. Гребные винты со ступицами расположены на наружных цили
