Description

Leitvorrichtung für Schiffsschrauben Gegenstand der Erfindung ist eine Anordnung zur Erhöhung des Wirkungsgrades der Schiffsschraube (Leitvorrichtung), und dies wird erfindungsgemäß dadurch bewirkt, daß die Wasserführung in und hinter der Schraube verbessert wird.Guide device for propellers is the subject of the invention an arrangement to increase the efficiency of the propeller (guiding device), and this is achieved according to the invention in that the water flow in and behind the screw is improved.

Die Erfindung ist in der Zeichnung beispielsweise und schematisch veranschaulicht. Es stellt dar Abb. i einen Längsschnitt durch eine Vorrichtung nach der Erfindung, wobei im Unterteil eine etwas andere Ausführungsform als im Oberteil dargestellt ist.The invention is shown in the drawing by way of example and schematically illustrated. It shows Fig. I a longitudinal section through a device according to the invention, with a slightly different embodiment than in the lower part Upper part is shown.

Abb.2 ist eine Rückansicht der Vorrichtung.Figure 2 is a rear view of the device.

Die Leitvorrichtung wird durch einen die Schraube 2 umgebenden Ring i gebildet. Der Ring besteht aus mehreren Lamellen, die gegen die Schraubenachse geneigt, gegebenenfalls auch gekrümmt sind und das Schraubenwasser durchtreten lassen. Der Ring kann durch Rippen 3 an eine um die Schraubenwelle herumgreifende und mit dem Heck des Schiffes fest verbundene Nabe q. angeschlossen oder auf eine andere geeignete Art mit dem Schiffskörper verbunden werden.The guide device is formed by a ring surrounding the screw 2 i formed. The ring consists of several lamellas that oppose the screw axis are inclined, possibly also curved, and allow the screw water to pass through. The ring can by means of ribs 3 to a gripping around the screw shaft and with Hub q firmly attached to the stern of the ship. connected or on another be connected to the hull in a suitable manner.

Durch diese Leitvorrichtung wird auch die Wirbelbewegung des Schraubenwassers, die einen schädlichen Einfluß auf die Sohle der Fahrstraße sowie auf das Ruder und damit auf die Steuerfähigkeit des Schiffes ausübt, abgeschwächt.The vortex movement of the screw water, which have a detrimental effect on the bottom of the driveway and on the rudder and thus exerts on the controllability of the ship, weakened.
