Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Erfindung betrifft eine Schraube mit . umsteuerbaren Flügeln, die sich von den bekannten ähnlichen Ausführungen dadurch unterscheidet, daß die Kulissen, deren Steine mit zentrischen Zapfen der Propellerflügel verbunden sind, in Schlitzen in der Nabe hin und her verschiebbar sind.The invention relates to a screw with. reversible wings that differ from the familiar Similar designs differ in that the scenes, the stones of which are connected to the central pin of the propeller blades are slidable back and forth in slots in the hub.

Auf der Zeichnung sind zwei Ausführungsbeispiele der Schraube dargestellt, und zwar In the drawing, two embodiments of the screw are shown, namely

ίο zeigt Fig. ι einen Längsschnitt, Fig. 2 eine Draufsicht, teilweise geschnitten, der einen Ausführungsform und Fig. 3 eine Draufsicht der Kulisse der anderen Ausführungsform.ίο shows Fig. ι a longitudinal section, Fig. 2 shows a Top view, partially in section, of one embodiment, and FIG. 3 is a top view the backdrop of the other embodiment.

An dem auf bekannte Art in der Längsrichtung der Welle 0 verschiebbaren Schleifring α sind die Kulissen b befestigt, welche durch die auf die Welle 0 gekeilte Nabe d außerhalb der Welle 0 hindurchgehen, derart, daß die zentrischen Zapfen k des Propellerflügels c von der Kulissenführung umfaßt werden und auf der Nabe d mit den eventuell als Kugellager ausgebildeten Kappen ή befestigt werden können, in welchen der untere verstärkte Teil f der Flügel c gelagert ist.On the slip ring α , which can be displaced in the longitudinal direction of the shaft 0 in a known manner, the scenes b are attached, which pass through the hub d wedged onto the shaft 0 outside the shaft 0, in such a way that the central pin k of the propeller blade c is surrounded by the link guide and can be attached to the hub d with the caps ή , which may be designed as ball bearings, in which the lower reinforced part f of the wing c is mounted.

Die zentrischen Zapfen k der Flügel sind in die Kulissensteine m vierkantig eingelassen. Die Kulissensteine gleiten in bogenförmigen Ausschnitten k der Kulisse b. The centric pegs k of the wings are set square in the sliding blocks m. The sliding blocks slide in arcuate cutouts k of the backdrop b.

Beim Verschieben der Kulissen werden, wie bekannt, die Kulissensteine verdreht, und hierdurch wird die Steigung der Flügel geändert. Die Verschiebung der Kulissen bedingt infolge der Bogenform der Ausschnitte k eine gewisse Bewegung der Kulissensteine m quer zur Schubrichtung der Kulissen. Bei der Ausführungsform nach Fig. 1 und 2 wird diese Bewegung dadurch ermöglicht, daß die Ausschnitte k in Gleitstücken J1 angeordnet und diese mit einem kleinen Spielraum in die Kulissen b gleitbar eingesetzt sind. Bei der Ausführungsform nach Fig. 3 ist der Flügelzapfen h in dem vierkantigen Kulissenstein m verschiebbar angeordnet.When moving the scenes, as is known, the sliding blocks are rotated, and this changes the pitch of the wings. The displacement of the scenes due to the arched shape of the cutouts k causes a certain movement of the sliding blocks m transversely to the direction of thrust of the scenes. In the embodiment according to FIGS. 1 and 2, this movement is made possible in that the cutouts k are arranged in sliders J 1 and these are slidably inserted with a small amount of play in the scenes b. In the embodiment according to FIG. 3, the wing pin h is arranged displaceably in the square sliding block m.
