Abstract

Die Erfindung betrifft einen Verstellpropeller für Motor- und Sportboote mit einer Nabe (1), daran in umfangsseitigen Ausnehmungen abgedichtet angeordneten Verstelltellern (20), die mittels einer Verstelleinrichtung um radiale Achsen verstellbar sind, und mit Flügeln (2), die mit einem in die zugeordnete Ausnehmung (14) eingreifenden Flügelfuß (26) am zugeordneten Verstellteller (20) lösbar befestigt sind, wobei jeder Verstellteller (20) mit einem in die Ausnehmung eindrehbaren, den Verstellteller (20) randseitig überfassenden Haltering (16) spielfrei, jedoch drehbar am Boden seiner Ausnehmung gehalten ist. Um das Auswechseln der Flügel (2) des Verstellpropellers zu vereinfachen, soll der Durchmesser des Flügelfußes (26) kleiner sein als der Durchmesser der Ausnehmung (14) und soll der Haltering (16) einerseits gegen die Wandung der Ausnehmung (14) und andererseits gegen den Verstellteller (20) abgedichtet sein.

Figure 00000001
The invention relates to an adjustable propeller for motor and sports boats with a hub (1), adjuster plates (20) arranged thereon in circumferential recesses, which can be adjusted by means of an adjusting device about radial axes, and with blades (2) which are connected to one in the assigned recess (14) engaging wing foot (26) are releasably attached to the associated adjustment plate (20), each adjustment plate (20) having a retaining ring (16) which can be screwed into the recess and surrounds the adjustment plate (20) on the edge without play, but can be rotated on the floor its recess is held. In order to simplify the replacement of the blades (2) of the variable pitch propeller, the diameter of the blade base (26) should be smaller than the diameter of the recess (14) and the retaining ring (16) should be against the wall of the recess (14) on the one hand and against the other the adjustment plate (20) be sealed.
