Description

Schaufel für Kreiselgebläse. Stoffschaufeln gemäß Patent 323848 werden bei Zentrifugalventilatoren verwendet, die j e nach den gestellten Bedingungen gekrümmte Schaufeln haben müssen. Gemäß der vorliegenden Erfindung soll an Stelle des Stoffes schwaches Stahlblech für die Schaufeln verwendet werden, denn bei größerer Schaufelhöhe ist auch dieses, Material noch elastisch genug, .um die erforderlichen. Krüm-@nungen annehmen zu können. Die beiliegenden Fig. i und 2 zeigen Ausführungsbeispiele der Anordnung. Auf dem Ventila'torblech a sind die Stehbolzen b angebracht, um welche das dünne Stahlblech c herumgelegt ist, welches durch die Nieten d zusammengehalten wird.Blade for centrifugal fan. Stock paddles according to patent 323848 are used in centrifugal fans which, depending on the conditions, must have curved blades. According to the present invention, instead of the material, weak steel sheet should be used for the blades, because with a larger blade height this material is still elastic enough to meet the requirements. To be able to accept curvatures. The accompanying FIGS. I and 2 show exemplary embodiments of the arrangement. On the Ventila'torblech a, the stud bolts b are attached, around which the thin steel sheet c is wrapped, which is held together by the rivets d.
