KAISERLICHES A IMPERIAL A
PATENTAMT.PATENT OFFICE.
Die bis jetzt bekannt gewordenen, elektrisch betriebenen Schleudergebläse, bei welchen der Anker des Elektromotors unmittelbar auf der Welle des Gebläses sitzt, haben den Nachtheil, dafs der Elektromotor eine Kreisfläche um die Welle verdeckt, so dafs die Gebläseflügel innerhalb eines obige Kreisfläche umgebenden Kreisringes zur Wirkung kommen, ganz gleichgültig, ob sich der Elektromotor auf der Saug- oder Druckseite des Schleudergebläses befindet.The electrically operated centrifugal blower that has become known so far, in which the The armature of the electric motor sits directly on the shaft of the blower, have the disadvantage, that the electric motor covers a circular area around the shaft, so that the fan blades inside of a circular ring surrounding the above circular area come into effect, no matter what, whether the electric motor is on the suction or pressure side of the centrifugal fan.
Vorliegender Erfindung nach wird bei einem unmittelbar angetriebenen Schleudergebläse möglichst die ganze Fläche der Flügel für die Gebläsewirküng dadμrch nutzbar gemacht, dafs der innere Durchmesser des ringförmigen Ankers und der äufsere Durchmesser der Flügel ganz oder nahezu gleich grofs sind.According to the present invention, a directly driven centrifugal fan is possible the entire surface of the blades has been made usable for the blower effect, so that the inner diameter of the ring-shaped anchor and the outer diameter of the wings whole or are almost the same size.
Beiliegende Zeichnung zeigt eine Ausführungsform eines solchen Gebläses in der Ansicht und im Radialschnitt, bei welcher der ringförmige Anker B des Elektromotors B C am Umfange der Flügel A unmittelbar mit denselben verbunden und der innere Durchmesser des Ankers gleich dem äufseren Durchmesser der Flügel bemessen ist, wodurch die ganze Fläche der Flügel mit Ausnahme der allenfalls vorhandenen Arme zur Saug- und Druckwirkung herangezogen wird. Die Feldmagnete C des Elektromotors umgeben in bekannter Weise den Anker und sind an einer durchbrochenen, das Gebläse umgebenden Wand D befestigt, an welcher auch die Welle E mittelst der Arme F gelagert ist.The accompanying drawing shows an embodiment of such a fan in the view and in radial section, in which the annular armature B of the electric motor BC is directly connected to the periphery of the blades A and the inner diameter of the armature is dimensioned equal to the outer diameter of the blades, whereby the whole area of the wing with the exception of any arms that may be present is used for suction and pressure. The field magnets C of the electric motor surround the armature in a known manner and are attached to a perforated wall D surrounding the fan, on which the shaft E is also supported by means of the arms F.
Unter Beibehaltung der angegebenen Beziehung zwischen den Flügeln und dem Anker können dieselben auch getrennt für sich neben einander auf der Welle E aufgekeilt sein bezw. an den ringförmigen Anker eines Elektromotors können Gebläseflügel in der angegebenen Weise angebracht werden.While maintaining the specified relationship between the wings and the armature, the same can also be wedged separately for themselves next to each other on the shaft E respectively. Fan blades can be attached to the ring-shaped armature of an electric motor in the specified manner.
