Buckauer screw

The Buckauer screw , also known as Wolf's ship's screw , is a ship's propeller .

The propeller was developed in 1876 by Rudolf Wolf at the suggestion of the shipowner Andreae , who is active in German river and canal shipping . In contrast to the cast-iron propellers used at the time, Wolf manufactured the propeller blades from sheet metal made from Siemens-Martin fluent iron, which was riveted to a cast steel hub . The wings were therefore easily exchangeable. After propeller damage, which often occurred in river navigation due to lower water levels, it was no longer the entire propeller, but only the affected wing that had to be replaced or repaired.

In addition, the otherwise necessary expensive molds were no longer required in production. Furthermore, the shape of the wings could be adapted to the respective application. A large number of mold plates with different slopes were used for shaping. The use of wide wings was typical, with which the influence of the diving depth was reduced.

The production was carried out by the R. Wolf machine factory in Buckau , which had developed special machines for this purpose. The name arose from the place of manufacture, today a district of Magdeburg . The Buckauer screw was widespread in river navigation especially at the end of the 19th century.
