Description

Die Erfindung bezieht sich auf einen Freiflügelpropeller; um welchen unter Fortfall der Flügelspitzen ein tragflügelartiger Mantel gelegt ist, nach Patent 8o5 848. Sie bezweckt die Ausnutzung der Vortriebswirkung des Außenmantels auch für Propeller, deren Flügel verstellbar sind.The invention relates to a free-wing propeller; about which With the elimination of the wing tips, a wing-like jacket is placed, according to the patent 8o5 848. It also aims to utilize the propulsion effect of the outer jacket for propellers with adjustable blades.

Gemäß 'der Eifindung ist der Propeller ein Verstellpropeller; dessen Flügel durch je einen zur Verstellachse der Flügel zentrischen Zapfen im Außenmantel gelagert sind. Durch die Lagerung der Flügel im Drehpunkt der Verstellbewegung wird der Verstellimpuls nicht gehemmt, und der Außenmantel behält seine Lage zur Propellerachse, da der Mantel als geschlossener Ring einheitlichen Profils am sich drehenden Propeller immer zentrisch zur Propellernabe bleibt. Weitere Befestigungsmittel sind aus dem gleichen Grunde nichterforderlich. Der Mantel kann jedem Propeller normaler Konstruktion nachträglich zugefügt werden.According to the invention, the propeller is a controllable pitch propeller; whose Wing by a pin in the outer jacket which is centric to the adjustment axis of the wing are stored. Due to the storage of the wing in the pivot point of the adjustment movement the adjustment pulse is not inhibited and the outer jacket retains its position in relation to the propeller axis, because the jacket is a closed ring with a uniform profile on the rotating propeller always remains centered on the propeller hub. Other fasteners are from the same reason not required. The jacket can be used with any propeller of normal construction can be added later.

Die Zeichnung zeigt ein Ausführungsbeispiel, und zwar in Fig. i eine Seitenansicht, in Fig. a eine Rückansicht, beide teilweise geschnitten, in Fig. 3 eine andere Lagerungsart der Flügelspitzen im Außenmantel.The drawing shows an exemplary embodiment, specifically in FIG Side view, in Fig. A a rear view, both partially cut, in Fig. 3 another way of mounting the wing tips in the outer jacket.

Die Flügel i des Verstellpropellers 2 sind an den Spitzen gekürzt. Um die gekürzten Flügel i -des Propellers a ist ein Mantel 3 gelegt, der mit Lägerbuchsen 4 für die an den Flügeln befestigten Drehzapfen 5 versehen ist. Die Mitten der Drehzapfens liegen zentrisch iur Verstellachse 6 der Flügel i: Zum Zusammenbau werden nach Auflegen des Mantels 3 die Drehzapfen 5 einzeln in die Lagerbuchsen 4 des Mantels 3 gesetzt und dann mit den Flügeln vernietet.The blades i of the controllable pitch propeller 2 are shortened at the tips. A jacket 3 is placed around the shortened wing i -des propeller a, which is provided with bearing bushes 4 for the pivot pins 5 attached to the wings. The centers of the pivot pins are centric iur adjustment axis 6 of the sashes i: For assembly, after placing of the casing 3, the pivot pins 5 are set individually in the bearing bushes 4 of the casing 3 and then riveted to the wings.

Man kann auch die Flügel mit einer Lagerbuchse versehen und im Mantel 3 einen Schraubzapfen 5' anordnen, so daß die Verbindung nach Ausschrauben des Schraubzapfens 5' lösbar ist, wie in Fig. 3 dargestellt.You can also provide the wings with a bearing bush and in the jacket 3 arrange a screw pin 5 'so that the connection after unscrewing the screw pin 5 'is detachable, as shown in FIG.
