Description

Die Erfindung betrifft einen Schiffsantrieb mittels eines Schaufelrades mit beweglichen Schaufeln, die vollständig untergetaucht arbeiten, und bei dem die Schaufeln bei jeder vollen Raddrehung eine Drehung von i 8o' um zur Radachse parallele Achsen machen. Derartige Schaufelräder sind 'bekannt. Es ist nun die Aufgabe der Erfindung, mit einem derartigen Schaufelrad .durch günstigen Einbau einen guten Propulsionswirkungsgrad zu erreichen.The invention relates to a ship propulsion system by means of a paddle wheel with moving blades that work completely submerged and in which the For every full revolution of the wheel, shovel a rotation of i 8o 'around parallel to the wheel axis Make axes. Such paddle wheels are known. It is now the job of the Invention, with such a paddle wheel .by favorable installation a good one To achieve propulsion efficiency.

Nach der Erfindung wird das Schaufelrad. mit waagerechter Achse in einer im Schiffsboden in Fahrtrichtung eingebauten Rinne so angeordnet, daß es vollständig innerhalb des Schiffsprofils liegt. Diese Einbauart bietet folgende Vorzüge: i. Ein seitliches Zurückwirbeln. des Wassers hinter die Schaufelflächen und ein dadurch entstehendes Herabsetzender Leistung wird verhindert.According to the invention, the paddle wheel. with horizontal axis in a channel built into the ship's bottom in the direction of travel so arranged that it is completely lies within the ship's profile. This type of installation offers the following advantages: i. A side spinning back. of the water behind the blade surfaces and a through it resulting degradation in performance is prevented.

2. Der Antrieb ist vor jeder Beschädigung geschützt.2. The drive is protected from any damage.

3. Das Schaufelrad ist auf beiden Seiten gelagert, wird von beiden Seiten angetrieben, ebenso werden die Schaufelflächen von beiden Seiten gesteuert; dadurch fällt die starke Beanspruchung auf Verdrehung des Schaufelantriebes und der Schaufelflächen fort.3. The paddle wheel is supported on both sides, used by both Driven sides, the paddle surfaces are also controlled from both sides; as a result, the heavy load falls on the rotation of the blade drive and of the blade surfaces.

4. Der Sog fällt fort, da die treilbende Kraft erst am Heck des Schiffes zur wollen Wirkung kommt. Durch den Einbau der Rinne, in den Schiffsrumpf am Kiel in Fahrtrichtung geht kein nutzbarer Schiffsraum verloren, da die Räume zu beiden Seiten der Rinne als Ballast-, Süßwasser- oder Brennstofftanks ausgebaut werden können. In der Zeichnung zeigt Abb. i einen Schnitt in Längsrichtung durch die Rinne und das Schaufelrad; Abb. 2 ist ein Schnitt vor dem Schaufelrad quer durch die Rinne, Abl>. 3 ein Längsschnitt durch den Maschinenraum.4. The suction disappears, since the driving force is only at the stern of the ship the wanting effect comes. By installing the gutter in the ship's hull on the keel In the direction of travel, no usable ship space is lost, as the spaces to both Sides of the channel can be expanded as ballast, freshwater or fuel tanks can. In the drawing, Fig. I shows a section in the longitudinal direction through the channel and the paddle wheel; Fig. 2 is a section in front of the paddle wheel across the channel, Lead>. 3 is a longitudinal section through the engine room.

Das Schaufelrad besteht aus den beiden Seitenscheiben b und den drei Schaufeln f, die drehbar um Achsen gelagert sind, die parallel zur Achse, des Schaufelrades sind. Seitenscheiben b und die Seitenteile 'der Schaufeln sind bündig mit der Rinnenwand w angeordnet. Die, Schaufeln stehen über Zahnräder z,zi mit zwei zum Schaufelrad (koaxi@alen Sonnenrädern i, i mit einem Übersetzungsverhältnis von i : 2 derart in Verbindung, daß die Schaufeln bei einer vollen Schaufelraddrehung um i8o° gedreht werden. Die Sonnenräder i, i' können dulch koaxiale Schneckenräder k, k' verstellt werden, so daB die Schubrichtung ohne Änderung der Drehrichtung des Schaufelrades umgesteuert werden kann. Die Schaufelradwelle a, ä ist in den Lagern d, d' gelagert, die Aden Schub auf den Schiffskörper übertragen: Neben den Lagern sind auf den Enden der Wellen a, a' Zahn- oder Kettenräder e, e' aufgekeilt, welche zum Antrieb des Schaufelrades dienen. Bei dem Ausführungsbeispiel wird das Schaufelrad von einer Dampfturbine p über die Ketten q und die Kettenräder e, e' getrieben. Bei größeren Schiffen sind zwei nebeneinanderliegend'e, durch eine Zwischenwand voneinander getrennte Schaufelräder, jedes mit eigener Antriebsmaschine, einzubauen; dadurch wird die Betriebssicherheit und die Manöverierfähigkeit des Schiffes erhöht.The paddle wheel consists of the two side disks b and the three blades f, which are rotatably mounted about axes that are parallel to the axis of the paddle wheel. Side plates b and the side parts' of the blades are arranged flush with the channel wall w. The blades are connected to the blade wheel via gears z, zi with two of the blades (koaxi @ alen sun gears i, i with a gear ratio of i: 2 in such a way that the blades are rotated by 180 ° with one full blade wheel rotation. The sun gears i, i 'may dulch coaxial worm gears k, k' can be adjusted, so that the thrust direction without changing the direction of rotation of the blade wheel can be reversed, the bucket wheel shaft a, is similar in the bearings d, stored d 'that transmit Aden thrust to the ship body. in addition The bearings are keyed to the ends of the shafts a, a ', toothed or chain wheels e, e', which are used to drive the paddle wheel. In the exemplary embodiment, the paddle wheel is driven by a steam turbine p via the chains q and the chain wheels e, e ' In larger ships, two paddle wheels lying next to one another, separated from one another by a partition, each with its own drive engine, are to be installed; and increases the maneuverability of the ship.
