Abstract

Radial blower wheel with blower impeller blades which are stamped out of the wheel base or set on the wheel base where the blades, in the direction of rotation of the blower impeller are inclined at an acute angle to the wheel base. Because of this arrangement, such a blower can handle a larger volume of air than is conventional blower with blades at right angles.

Beschreibung mit Patentanspruch zur Patent- und Gebrauchsmusterhilfsanmeldung vom 24.10.1973 der Firma Dr. Werner Rohrs "KG.,■ 8972 Sonthofen, betreffend:Description with patent claim for patent and utility model auxiliary application dated October 24, 1973 by the company Dr. Werner Rohrs "KG., ■ 8972 Sonthofen, concerning:

"Radialventilatorrad mit in Drehrichtung"Radial fan wheel with in the direction of rotation

im spitzen Winkel zum Radboden geneigteninclined at an acute angle to the wheel base

Flügeln" ; ; \ ;_^^^^ : : 'Wings ";; \; _ ^^^^:: '

Die Erfindung betrifft ein Radialventilatorrad, bei welchem auf dem Radboden, der die Nabe trägt, die Flügel aufgesetzt sind oder aus dem Boden herausgestanzt und hochgekantet sind.The invention relates to a radial fan wheel, in which on the Wheel base that carries the hub, the wings are attached or off are punched out and edged from the bottom.

Derartige Ventilatoxräder werden zur Erzeugung eines Windstromes benützt. \ - :Such Ventilatoxräder are used to generate a wind current used. \ -:

Bei-solchen Verttilatorrädern werden die aufgesetzten oder aus dem Boden hochgekanteten Flügel im rechten Winkel zum Radboden gestellt.In-such fan wheels are the attached or from the Bottom edged wing placed at right angles to the wheel base.

Der Erfindung liegt die Aufgabe zugrunde, ein besonders billig herzustellendes Ventilator rad, bei dem die Flügel aus der Fläche, des Radbodens ausgestanzt und hochgekantet oder auf dem Radboden aufgesetzt sind, besonders leistungsfähig zu machen.The invention is based on the object of a particularly cheap Fan wheel to be produced, in which the blades are made from the area of the wheel base are punched out and edged or placed on the wheel base, to make it particularly efficient.

Die Aufgabe wird dadurch gelöst, daß die aus dem Radboden ausgestanzten und hochgekanteten Ventilatorradflügel bzw« die auf den Radbodenaufgesetzten Ventilatorradflügel nicht im rechten Winkel, sondern in Drehrichtung im spitzen Winkel zum Radboden aufgesetzt bzw« hochgekantet sind.The object is achieved in that the punched out of the wheel base and upright fan wheel blades or the fan wheel blades placed on the wheel base not in the right one Angle, but in the direction of rotation at an acute angle to the wheel base or «are edged.

Die Vorteile der Erfindungbestehen darin, daßVentilatorräder · mit im spitzen Winkel zum Radboden und zur Drehrichtung stehenden Flügeln eine größere Iiuftmenge befördern als Ventilatorräder, . deren Flügel rechtwinkligstehen. . . ·The advantages of the invention are that fan wheels with standing at an acute angle to the wheel base and to the direction of rotation Blades convey a larger amount of air than fan wheels,. whose wings are at right angles. . . ·

Ein Ausführungsbeispiel der Erfindung ist; in der Zeichnung dargestellt und wird im folgenden näher beschrieben:An embodiment of the invention is; in the drawing and is described in more detail below:

Figur 1 zeigt die Draufsicht auf das Ventilatorrad. Der Radboden (l\ trägt die Nabe (2) und die Flügel (3).Im dargestellten Beispiel sind die Flügel aus dem Radboden herausgestanzt, wodurch sich die ATissparung (4) ergibt. S Ö 9 8 11/ Ö 1 9 ÖFigure 1 shows the top view of the fan wheel. The wheel base (l \ carries the hub (2) and the wings (3). In the example shown, the wings are punched out of the wheel base, resulting in the Ais saving (4). S Ö 9 8 1 1 / Ö 1 9 Ö

Figur 2 zeigt einen Querschnitt durch das Ventilatorrad. Der Flügel (3) steht in Drehrichtung gesehen nicht rechtwinklig zum Radboden (1) , sondern im spitzen Winkel oC zu ihm, wodurch das Ventxlatorrad eine größere Förderleistung erhält.Figure 2 shows a cross section through the fan wheel. Seen in the direction of rotation, the blade (3) is not at right angles to the wheel base (1) , but at an acute angle oC to it, which means that the ventilator wheel receives a greater flow rate.
