Description
Radialgebläse Die vorliegende Erfindung bezieht sich auf ein Radialgebläse, das dadurch gekennzeichnet ist, dass sein Schaufelrad als Aussenläuferrotor eines elektrischen Motors ausgebildet ist.
In der beiliegenden Zeichnung sind zwei Aus führungsbeispiele des Erfindungsgegenstandes schema tisch und im Schnitt dargestellt. Es zeigen: Fig. 1 ein einseitig saugendes Gebläse, Fig. 2 ein zweiseitig saugendes Gebläse.
In Fig. 1 ist ein einseitig saugendes Gebläse dar gestellt. Das Gehäuse 1 des Gebläses ist nur schema tisch angedeutet. Der Stator 2 des Motors ist mittels Schrauben 3 an dem Gehäuse 1 befestigt. Er weist eine axiale Bohrung 4 auf, in welcher Kugellager 5 befestigt sind. In diesen Kugellagern 5 ist eine Welle 6 drehbar gelagert, die an ihrem äusseren Ende an dem den Sta- tor 2 umschliessenden Rotor 7 befestigt ist. Dieser Rotor 7 ist durch das Schaufelrad selbst gebildet und trägt die Schaufeln B.
Die Luft wird in Richtung des Pfeiles<I>A</I> angesaugt und in Richtung des Pfeiles<I>V</I> ver drängt. Wird der elektrische Motor derart ausgebildet, dass er bei 890 U/m eine Leistung von 0,1 PS eilt wickelt, so kann die beförderte Luftmenge 2200-3380 m3/St betragen.
In Fig. 2 ist ein zweiseitig saugendes Gebläse dar gestellt. An den Gehäusewänden ist eine Achse 9 fest angebracht, auf welcher der Stator 10, dessen Wicke lung 11 angedeutet ist, befestigt ist. An seinen Enden trägt der Stator Kugellager 12, die zur drehbaren Lagerung des Rotors 13 dienen. Die Achse 9 ist als Hohlachse ausgebildet, so dass eine Stromzufuhrlei- tung 14 eingeführt werden kann. Die Luft wird in Richtung der Pfeile A angesaugt und in Richtung des Pfeiles V verdrängt.
Radial fan The present invention relates to a radial fan, which is characterized in that its impeller is designed as an external rotor of an electric motor.
In the accompanying drawings, two exemplary embodiments of the subject invention are shown schematically and in section. There are shown: FIG. 1 a fan with suction on one side, FIG. 2 a fan with suction on both sides.
In Fig. 1 a single-sided suction fan is provided. The housing 1 of the fan is only indicated schematically. The stator 2 of the motor is fastened to the housing 1 by means of screws 3. It has an axial bore 4 in which ball bearings 5 are attached. A shaft 6 is rotatably mounted in these ball bearings 5 and is fastened at its outer end to the rotor 7 surrounding the stator 2. This rotor 7 is formed by the impeller itself and carries the blades B.
The air is sucked in in the direction of the arrow <I> A </I> and displaced in the direction of the arrow <I> V </I>. If the electric motor is designed in such a way that it develops a power of 0.1 HP at 890 rpm, the air volume transported can be 2200-3380 m3 / h.
In Fig. 2, a double-sided suction fan is provided. On the housing walls an axis 9 is fixedly attached, on which the stator 10, whose Wicke ment 11 is indicated, is attached. At its ends, the stator has ball bearings 12 which are used to support the rotor 13 in a rotatable manner. The axis 9 is designed as a hollow axis so that a power supply line 14 can be introduced. The air is sucked in in the direction of the arrows A and displaced in the direction of the arrow V.
