Abstract

Изобретение относитс к судостроению и касаетс конструкции лопастных движителей. Цель изобретени - повышение маневренности судна за счет изменени величины и направлени упора движител . Оба приводных вала 1 вращаютс от двигател 16 в разные стороны. Кажда лопасть 4 колеблетс вокруг двух осей: вокруг вертикальной оси элемента 7 и вокруг точки Б. Причем одна лопасть 4 на одном валу создает упор "вперед", а друга на другом валу - "назад". Дл изменени упора движител необходимо уменьшить угол эксцентриситета одного из кривошипов, дл чего с помощью штока 14 двигают ползунок 13 из положени А в положение В, который подвигает стержень 11, в свою очередь пот гивающий стержень 10, в результате чего изменитс эксцентриситет кривошипа 2 относительно оси приводного вала 1 вплоть до 0° /положение В/. В этом случае лопасть неподвижна и занимает положение по потоку. Независимо мен эксцентриситет каждого кривошипа, можно добитьс требуемого направлени движени . 2 ил.FIELD OF THE INVENTION The invention relates to shipbuilding and concerns the construction of blade propellers. The purpose of the invention is to increase the maneuverability of the vessel by changing the size and direction of the thrust support. Both drive shafts 1 rotate from engine 16 in opposite directions. Each blade 4 oscillates around two axes: around the vertical axis of element 7 and around point B. And one blade 4 on one shaft creates an emphasis "forward", and a friend on another shaft - "backward". To change the thrust of the drive, it is necessary to reduce the eccentricity angle of one of the cranks, for which with the help of the rod 14 the slider 13 is moved from position A to position B, which moves the rod 11, which in turn pulls the rod 10, as a result of which the crank eccentricity 2 changes relative to drive shaft 1 up to 0 ° / position B /. In this case, the blade is stationary and takes a position on the flow. Independently of the eccentricity of each crank, the desired direction of movement can be achieved. 2 Il.

Claims

Claim

The propulsion and propulsion complex of the vessel, comprising a drive shaft, a blade rigidly fastened to a sleeve mounted to rotate on the crankshaft of the drive shaft and provided with two consoles with through coaxial holes in which the fingers of the fork-like element are mounted pivotally mounted on a bracket mounted on the hull vessel, and the blade is made in the form of a rigid wing of a symmetrical profile, the plane of which is perpendicular to the axis of the crank shaft, characterized in that, in order to increase maneuver the vessel by changing the magnitude and direction of the thrust stop, it is equipped with a control mechanism that includes a power drive with a slider and traction pivotally connected to each other, with one end of the crank and the slider, while the other end of the crank is pivotally mounted on the drive shaft.
