Description

  

  Schiffsantriebsvorrichtung.    Die Erfindung betrifft eine Schiffs  antriebsvorrichtung, und besteht darin, dass  ein auf einer stehenden Welle angeordneter  sehraubenartiger Propeller in einem dreh  baren, annähernd S-förmig gekrümmten  Wasserführungskanal angeordnet ist, zum  Zweck, das Schiff mittelst eines stets in dem  selben Drehsinn umlaufenden schrauben  artigen Propellers nicht nur in der Vorwärts  richtung antreiben, sondern durch Drehen des  Wasserführungskanals in verschiedene Win  kellagen auch umsteuern, steuern und beim  Stillstand auf dem Platz drehen zu können.  



  Ein Ausführungsbeispiel des Erfindungs  gegenstandes ist auf der Zeichnung darge  stellt.  



  Fig. 1 ist ein Schnitt nach der Linie I-I  der Fig. 2,  Fig. 2 ein Schnitt nach der Linie II-II  der Fig. 1.  



       a    ist das Heck eines Schiffes und b eine  an sich bekannte, von einer nicht gezeich  neten Maschine durch die Welle c angetrie  bene Schiffsschraube. Die Schraube ist, an-    statt wie bisher auf einer liegenden Welle an  geordnet zu sein, auf eine     stehende    Welle d  aufgekeilt, und in einem annähernd S-förmig  gekrümmten, um die Schraube drehbaren  Wasserführungskanal f angeordnet, von dem  das in vertikaler Richtung von der Schraube  bewegte Wasser in annähernd horizontal ge  richtete Zu- und Abflussströme umgelenkt  wird.

   Die stehende Schraubenwelle ist durch  ein Kegelrädergetriebe mit der Welle c ver  bunden und das aussen zylindrisch ausgebil  dete Gehäuse des S-förmigen Kanals ist     mit-          telst    eines Stirnrädergetriebes g an die  Steuerradwelle h angeschlossen.  



  In der gezeichneten Lage des Kanals f  ist der vom ganzen Aggregat erzielte     Schub     nach vorn gerichtet und das     Schiff    wird in  normaler Weise in der Vorwärtsrichtung an  getrieben. Wird das Gehäuse durch das  Steuerrad um 180<B>'</B> gedreht, so wird die       Schubrichtung    umgekehrt, und das Schiff  wird auf     Rückwärtsfahrt        umgesteuert.    Wird  das Gehäuse um     weniger    als<B>180'</B> gedreht,  so wird der Schub mehr oder weniger quer      zur .Schiffsachse eingestellt, so dass das Schiff  entweder seine Fahrtrichtung ändert oder  aber auf dem Platze sich dreht, wenn es im  Stillstand sich befindet.

   Um beim Um  steuern -des Schiffes einen zeitweisen     Schub     in der Querrichtung zu vermeiden, können  zu beiden Seiten des drehbaren     Kanals     Wände so angeordnet sein, dass sie die     Ein-          und    Austrittsöffnungen des Kanals f schlie  ssen, solange dieser quer gerichtet ist. Die  Wände können au-eh beweglich angeordnet  sein, derart, dass sie ausser Wirkung gebracht  werden können, wenn dem     Schub    eine Quer  richtung gegeben werden soll.



  Marine propulsion device. The invention relates to a ship propulsion device, and consists in that a very dome-like propeller arranged on a standing shaft is arranged in a rotatable, approximately S-shaped curved water duct, for the purpose of driving the ship by means of a screw-like propeller always rotating in the same direction of rotation not only to drive in the forward direction, but also to change direction, steer and turn when standing still on the square by turning the water duct in different angular positions.



  An embodiment of the subject invention is on the drawing provides Darge.



  1 is a section along the line I-I of FIG. 2, FIG. 2 is a section along the line II-II of FIG.



       a is the stern of a ship and b is a known per se, propeller driven by a non-signed machine through the shaft c. The screw is instead of being arranged on a horizontal shaft as before, wedged onto a standing wave d, and arranged in an approximately S-shaped curved water duct f rotatable around the screw, of which the vertical direction of the Screw moving water is diverted into almost horizontally directed inflow and outflow currents.

   The standing screw shaft is connected to the shaft c by a bevel gear mechanism and the outside cylindrical housing of the S-shaped channel is connected to the control wheel shaft h by means of a spur gear mechanism g.



  In the drawn position of the channel f, the thrust achieved by the whole unit is directed forward and the ship is driven in the normal manner in the forward direction. If the housing is turned 180 <B> '</B> by the steering wheel, the direction of thrust is reversed and the ship is switched to reverse. If the housing is rotated by less than <B> 180 '</B>, the thrust is adjusted more or less transversely to the ship's axis, so that the ship either changes its direction of travel or turns on the spot when it is stationary located.

   In order to avoid a temporary thrust in the transverse direction when steering the ship, walls can be arranged on both sides of the rotatable channel in such a way that they close the inlet and outlet openings of the channel f as long as it is directed transversely. The walls can also be arranged to be movable, in such a way that they can be rendered inoperative if the thrust is to be given a transverse direction.
