Description

Verstellschrauhe mit Doppelflügel Das Patent 867 498 behandelt eine Verstelluftschraube, bei der die Schraubenflügel von zwei Flügelarmen gebildet werden, die in einem bestimmten Abstand hintereinanderliegen und von dem gemeinsamen Schaftteil, mit dem sie einheitlich zusammengefäßt sind, ausgehen. Durch diese Art der Anordnung ergeben sich Vorteile in bezug auf die Strömung und auf die Festigkeit, besonders durch Ausgleich der Zentrifugahnomente. Hiermit wird der Eriindungsgedänke auf Verstellschrauben für Wasserfahrzeuge ausgedehnt, insbesondere auf solche, die mit großer Geschwindigkeit fahret.Adjustment screw with double wing. Patent 867 498 deals with a Adjusting screw, in which the screw wings are formed by two wing arms, which are at a certain distance one behind the other and from the common shaft part, with which they are uniformly summarized, go out. By this type of arrangement there are advantages in terms of flow and strength, especially by balancing the centrifugal moments. Herewith the idea of the invention is applied to adjusting screws extended to watercraft, especially those traveling at great speed drives.
