Me Srflndusg betrifft eia doppelseitig ansaugendes für Hadialgebläse, insbesondere für fieislüfter. Bisher es üblich die Schaufeln des leafrades einsein herzustellen and durch Sehweifien oder litten zwischen des auf der Aa. -triebsiielle angeordneten Schaufelträger und swei diesesi gegenüberstehenden BBc^seheiben eu. befestigen· Biese Art der Herstellung ist uastäsdlieh, «eil die Einselteile des Laufrades genau zentrisch zueinander susaaaengebaut werden müssen* Durch die vielen Verbindungsstellen besteht saß«räea die Gefahr, daß die Schaufeln sich während des Betriebes lockern und das Gebläse zerstören«Me Srflndusg concerns a double-sided intake for Hadial blowers, in particular for fieislüfter. Up to now it has been customary to make the blades of the leafrade alone and by sight or suffered between the on the aa. -drive arranged blade carriers and two opposite BBc ^ see eu. attaching this type of manufacture is essential, because the individual parts of the impeller must be built exactly centric to each other
Eine wesentlich einfachere Herstellungsweise wird erfindungsgemäß dadurch erreicht, daß der Schaufelträger und die Schaufeln in einem Stück aus Blech hergestellt und die Schaufel» durch abwechselndes Umbiegen nach der einen oder der @ndBV£& Seite des Schaufelträgers gebildet sind« Durch dies® Ausbildung des Laufrades entfallen sämtliche BsfostigongostolleaA much simpler production method is achieved according to the invention in that the blade carrier and the blades are made in one piece from sheet metal and the blade » by alternately bending over according to one or the @ ndBV £ & Side of the blade carrier are formed «This® design of the impeller eliminates all Bsfostigongostollea zwischen dem Schaufelträger und den einseifen Schaufeina Di©between the shovel carrier and the soap Schaufeina Di ©

Weiterhin empfiehlt es sich, den Schaufelträger topfförmig auszubilden. Durch diese Auebildung erhält das G-ebläserad am Habenteil eine höhere Verwindungesteifigkeit. Außerdem kann der Antriebsmotor innerhalb der einen Hälfte des Gebläserades angeordnet werden, wodurch die Bauhöhe des Gebläses verringert wird.It is also recommended that the blade carrier be pot-shaped to train. This development gives the blower wheel a higher torsional stiffness on the hull part. aside from that the drive motor can be arranged within one half of the fan wheel, reducing the overall height of the fan is decreased.
