Description
Die Erfindung betrifft einen Kolben für große Durchmesser, insbesondere für Gebläse. Derartige Kolben wurden bisher in der Regel als Hohlgußkörper ausgeführt, wobei durch innere radial stehende Rippen die notwendige Steifigkeit und Festigkeit zu erreichen gesucht wurde. Derartige Kolben fallen sehr schwer aus und haben vom gießereitechnischen Standpunkte aus ungünstige ίο Formen.The invention relates to a piston for large diameters, in particular for fans. Such pistons have hitherto been designed as a hollow cast body, with the internal radially standing ribs The aim was to achieve the necessary rigidity and strength. Such pistons are very difficult and are unfavorable from a foundry point of view ίο forms.
Gegenstand der Erfindung ist ein Kolben, bei dem die notwendige Steifigkeit der verhältnismäßig dünnen Kolbenwand, statt wie bisher durch Rippen, durch eine gewellte Form der Kolbenwand geschaffen wird.The invention relates to a piston in which the necessary rigidity of the relatively thin piston wall, instead of ribs, as before, with a corrugated one Shape of the piston wall is created.
•Der neue Kolben ist auf der Zeichnung dargestellt, und zwar zeigt:• The new piston is shown in the drawing and shows:
Fig. ι den Kolben im Querschnitt,Fig. Ι the piston in cross section,
Fig. 2 einen abgewickelten Schnitt des Kolbenumfangs an der Stelle a-b der Fig. i.FIG. 2 shows a developed section of the circumference of the piston at the point from FIG.
Die Wellen verlaufen in der Richtung desThe waves run in the direction of the
Kolbenumfangs, die Wellentäler also radial.Piston circumference, so the wave troughs are radial.
Auf diese Weise wird bei kleinem Gewicht des Kolbens und sehr einfachen, auch bei sehr großen Kolben leicht ausführbaren Formen a5 eine erhebliche Steifigkeit erreicht, welche die Anwendung von Rippen oder anderen Versteifungen erübrigt. Der Kolben kann sowohl als einfacher wie auch als doppelwandiger Kolben ausgeführt werden. Man wird die Wellen meist so ausbilden, daß sie nach dem Umfange zu flacher werden, die Tiefe ihrer Täler also abnimmt, um das größte Widerstandsmoment an der Nabe zu erhalten. Anstatt einer gleichmäßig fortlaufenden WeI-lenlinie genügt es manchmal, an einzelnen Stellen radial verlaufende Eindrückungen oder Einbuchtungen der Kolbenwand auszuführen. In this way, with a low weight of the piston and very simple shapes a 5, which can be easily implemented even with very large pistons, considerable rigidity is achieved, which makes the use of ribs or other reinforcements unnecessary. The piston can be designed as a single or double-walled piston. The shafts are usually designed in such a way that they become too shallower in circumference, i.e. the depth of their valleys decreases, in order to obtain the greatest moment of resistance at the hub. Instead of a uniformly continuous wavy line, it is sometimes sufficient to make radial indentations or indentations on the piston wall at individual points.
