Description

Abdichtung der feststehenden Abdeckung gegenüber dem vom Läufer gebildeten Gehäuse eines Außenläufermotors Gegenstand der Erfindung ist eine Abdichtung gegen Feuchtigkeitseinflüsse bei Außenläufermotoren, vorgesehen zwischen dem vom Läufer gebildeten Gehäuse und einer feststehenden Abdeckung, z. B. einer Abdeckhaube od. dgl.Sealing of the fixed cover against that formed by the runner Housing of an external rotor motor The invention relates to a seal against Influences of moisture in external rotor motors, provided between that of the rotor formed housing and a fixed cover, for. B. a cover hood. like

Bei Motoren, die wenigstens eine Abdeckhaube aufweisen, besteht die Gefahr, daß niederschlagende Feuchtigkeit zwischen dem Spalt in den Motor eindringt, der durch das Gehäuse und die Abdeckhaube gebildet ist.For engines that have at least one cover, the Danger of precipitating moisture entering the motor between the gap, which is formed by the housing and the cover.

Aufgabe der Erfindung ist es, diesem Nachteil zu begegnen.The object of the invention is to counter this disadvantage.

Erfindungsgemäß wird daher vorgeschlagen, an dem zur Abdeckhaube weisenden Gehäuseteil eine umlaufende Vertiefung - vorzugsweise im Querschnitt V-förmig ausgebildet - vorzusehen, wobei die zum Motorengehäuse weisende freie Kante der Abdeckhaube bis zum Ansatz der Vertiefung reicht. Diese V-förmige Vertiefung kann auch im Kurzschlußring der Läuferkäfigwicklung angeordnet sein.According to the invention it is therefore proposed on the one pointing to the cover hood Housing part has a circumferential recess - preferably V-shaped in cross section - to be provided, whereby the free edge of the hood facing the motor housing until the beginning of the deepening. This V-shaped recess can also be in the short-circuit ring the rotor cage winding be arranged.

Durch diese Maßnahme wird nunmehr keine Feuchtigkeit mehr in das Innere des Motorengehäuses gelangen. Bei den Außenläufermotoren soll es sich vorzugsweise um solche handeln, die Flügelräder aufnehmen bzw. bei denen am Gehäuse Flügelräder vorgesehen sind.As a result of this measure, moisture no longer gets into the interior of the motor housing. In the case of external rotor motors, it should preferably be be those that accommodate impellers or those on the housing impellers are provided.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt.An exemplary embodiment is shown in the drawing.

Am Motor 1 sind Flügelräder vorgesehen. Selbstverständlich können auch ein oder mehrere Flansche od. dgl. zum Befestigen der Flügelräder an dem Gehäuse angegossen oder befestigt sein.Impellers are provided on the engine 1. Of course you can also one or more flanges or the like for attaching the impellers to the housing be cast or attached.

An der flachen Seite des Gehäuses ist eine Abdeckhaube 3 angebracht. Die Abdeckhaube 3 begrenzt auf einer Seite eine Vertiefung 2, die in diesem Falle V-förmig ausgebildet und hier im Kurzschlußring 4 vorgesehen ist. Sie kann durch bekannte Arbeitsverfahren, z. B. durch Eindrehen, gefertigt sein.A cover 3 is attached to the flat side of the housing. The cover 3 delimits a recess 2 on one side, which in this case V-shaped and is provided here in the short-circuit ring 4. She can get through known working methods, e.g. B. be made by screwing.

Das auf den Motor tropfende Wasser fließt in die Vertiefung 2 und tropft bei ruhendem Motor nach unten ab bzw. es wird bei rotierendem Motor abgeschleudert. Es ist also nicht möglich, daß das Wasser zwischen dem Motorengehäuse und der Abdeckhaube eindringen kann.The water dripping on the motor flows into the recess 2 and drips down when the engine is idle or it is thrown off when the engine is rotating. So it is not possible that the water between the motor housing and the cover can penetrate.
