Abstract

Two propellers (1, 2) are housed inside a tube (3) which is open at both ends, the propellers being rotated in the same direction, but at different speeds. The first propeller is mounted on a hollow drive shaft (5) and rotated at a lower speed than the second propeller, which is mounted on a drive shaft (4) extending through the hollow shaft. Two identical size pinions provided on the engine output shaft (8) are used to drive a large pinion on the hollow shaft and a small pinion on the inner shaft.

Description

Die Erfindung besteht darin, daß sich in einem Rohrkörper zwei Schiffsschrauben befinden, die eine gleichgerichtete Rotationsbewegung haben, jedoch mit unterschiedlicher DrehgeschwindigkeitDer Röhrenkörper ist an beiden Enden offen,die Ansaugschraube(1) hat eine geringere Drehgeschwindigkeit,während die zweite Schraube(2) eine höhere Drehgeschwindigkeit besitzt. Die unterschiedlichen Rotiergeschwindigkeiten werden über ein Getriebe (7) bewirkt wobei die Schraube 1 über die Hohlachse 5 und Schraube 2 über die Achse 4 angetrieben wird. Die Ritzel beider Achsen haben einen unterschiedlichen Durchmesser, die schneller drehende Schrabe 2 hat den kleineren Durchmesser. Der Antriebsmotor wird nur an einer Achse (8) angeschlossen auf der sich zwei gleichgroße Antriebsritzel befinden.,diese sind jeweils mit den Antriebsritzelnder Achsen 4 u.5 verbunden.The invention consists in the fact that there are two propellers in a tubular body, which rotate in the same direction, but with a different rotational speed. 1 ) has a lower rotation speed, while the second screw ( 2 ) has a higher rotational speed. The different rotation speeds are controlled by a gear ( 7 ) causes the screw 1 over the hollow axis 5 and screw 2 over the axis 4 is driven. The pinions of both axes have different diameters, the faster rotating scratch 2 has the smaller diameter. The drive motor is only on one axis ( 8th ) connected on which there are two equally large drive pinions, these are each with the drive pinion axes 4 u , 5 connected.

Der Erfindung liegt die Aufgabe zugrunde einen mögliichst energiesparenden Schiffsantrieb zu schaffen. Dieses wird dadurchbewirkt, daß eine gradlinige Druckwelle entsteht, während bei denbisherigen Schraubenantrieben die Druckwelle sich halbkegelförmig bildel.The invention is based on the object one as possible to create energy-saving ship propulsion. This is accomplished that a straight-line pressure wave arises, while in the previous screw drives the pressure wave is semi-conical bildel.
