Description
Kühlluftführung an einem elektrischen Einbaumotor Um bei einem elektrischen Einbaumotor, dessen gegossener, das Blechpaket aufnehmender Tragrahmen mit Ausschnitten an den Stellen der sich gegenüberliegenden Abflachungen des Blechpakets versehen ist, in einfachster Weise Luftkanäle zur äußeren Kühlung des Blechpakets und der Feldspule zu erhalten, sind erfindungsgemäß im Bereich der Blechpaketabflachungen nachträglich dünne, die Ausschnitte im Tragrahmen abdeckende Scheiben aus nichtmagnetischem Werkstoff lose in den Rahmen. eingesteckt und so verspannt, daß sie sich zu Luftkanälen aufwölben.Cooling air duct on an electric built-in motor To be used in an electric Built-in motor, its cast support frame with cutouts that accommodates the laminated core provided at the points of the opposite flats of the laminated core is, in the simplest possible way, air ducts for external cooling of the laminated core and the To obtain field coils are, according to the invention, in the area of the laminated core flats subsequently thin, non-magnetic disks covering the cutouts in the support frame Material loose in the frame. plugged in and so braced that they become air ducts bulge.
Jede Scheibe kann sich mit einem verbreiterten Teil im Bereich der Lagerbügel von einem Bügelarm des Tragrahmens zum anderen Bügelarm erstrecken. Dabei ruht der verbreiterte Scheibenteil auf dem Blechpaket auf. Die durch die Scheiben gebildeten Luftkanäle können also eine verschiedene Höhe aufweisen. Durch die beiden eingesteckten Scheiben ergänzt sich der mit Ausschnitten versehene Tragrahmen gewissermaßen zu einem zylindrischen Gehäuse.Each disc can have a widened part in the area of the Bearing bracket extend from one bracket arm of the support frame to the other bracket arm. Included the widened disk part rests on the laminated core. The one through the panes The air channels formed can therefore have a different height. Through the two Inserted panes complement the support frame provided with cutouts to a certain extent to a cylindrical housing.
In der Zeichnung ist ein Ausführungsbeispiel des Tragrahmens eines Einbaumotors ohne Anker dargestellt.In the drawing, an embodiment of the support frame is one Built-in motor shown without armature.
Fig. 1 zeigt den Tragrahmen, von unten gesehen; Fig.2 ist ein senkrechter Schnitt nach der Linie II-II der Fig. 1.Fig. 1 shows the support frame, seen from below; Fig.2 is a vertical one Section along the line II-II of FIG. 1.
Der einstückige, beispielsweise im Spritzgußverfahren hergestellte Tragrahmen besteht aus einem unteren Ring oder Ringflansch 1, von dem sich die beiden Rahmenhälften 2 nach oben erstrecken, die weiter oben in den Bügel 3 übergehen. Die beiden je einen Ausschnitt 4 zwischen sich aufweisenden Rahmenhälften 2 sind mit dem Blechpaket 5 zusammengegossen. In den senkrechten Bügelarmen 3' befinden sich Ausschnitte 6 zur Aufnahme der Kohlenbürstenhalter. Oben im Bügel 3 ist die zentrale Bohrung 7 zur Aufnahme des Lagers für das eine oder obere Ende der Ankerwelle vorgesehen.The one-piece, for example manufactured by injection molding Support frame consists of a lower ring or ring flange 1, from which the two Frame halves 2 extend upwards, which merge further up into bracket 3. The two frame halves 2 each having a cutout 4 between them cast together with the laminated core 5. Located in the vertical bracket arms 3 ' cutouts 6 to accommodate the carbon brush holder. At the top of bracket 3 is that central bore 7 for receiving the bearing for one or the upper end of the armature shaft intended.
Das Blechpaket 5 ist an sich gegenüberliegenden Stellen mit Abflachungen 12 versehen, die im Bereich der Ausschnitte 4 der Rahmenhälften 2 liegen. Diese Abflachungen 12 bilden zusammen mit den lose eingesteckten Scheiben die beiden Luftkanäle 13. Eine solche, beispielsweise aus sehr dünnem Preßspan bestehende Scheibe 14 ist in den Fig. 1 und 2 gestrichelt dargestellt. Die Scheibe 14 ist unter Rufwölbung zwischen die Kanten des Ausschnitts 4 eingesteckt, wobei sie unten in den Rahmenring 1 eingreift. Die Scheibe 14 deckt dabei die Abflachung 12 des Blechpakets 5 ab und bildet so den Luftkanal 13. Im gezeichneten Beispiel besitzt die Scheibe oben einen verbreiterten Teil M', der sich von der einen senkrechten Fläche eines Bügelarmes 3' zur senkrechten Fläche des anderen Bügelarmes erstreckt. Der vom Scheibenteil 14' gebildete Bogen erstreckt sich in Fig. 1 von der mit a bezeichneten Stelle zur gegenüberliegenden Stelle b. Die waagerechte Oberfläche des Blechpakets 5 bildet dabei vorzugsweise einen Anschlag, der die Einsteckbewegung der Scheibe 14, 14' begrenzt. Der Scheibenteil 14' liegt also mit seinen den Teil 14 überragenden Kanten auf dem Blechpaket 5 auf. Die verbreiterten Scheibenteile 14' bilden zusammen mit den Bügelarmen 3' einen etwa zylindrischen Luftkanal, der sich je nach den Kühlungserfordernissen mehr oder weniger weit nach oben über das Blechpaket erheben kann.The laminated core 5 is provided with flattened areas 12 at opposite points, which are located in the region of the cutouts 4 of the frame halves 2. These flattened areas 12, together with the loosely inserted disks, form the two air ducts 13. Such a disk 14, for example consisting of very thin pressboard, is shown in phantom in FIGS. The disk 14 is inserted between the edges of the cut-out 4 with a bulging ring, engaging the frame ring 1 at the bottom. The disk 14 covers the flattening 12 of the laminated core 5 and thus forms the air duct 13. In the example shown, the disk has a widened part M 'at the top, which extends from one vertical surface of a bracket arm 3' to the perpendicular surface of the other bracket arm . The arc formed by the disk part 14 'extends in FIG. 1 from the point designated by a to the opposite point b. The horizontal surface of the laminated core 5 preferably forms a stop which limits the insertion movement of the disk 14, 14 '. The disc part 14 ′ rests on the laminated core 5 with its edges projecting beyond the part 14. The widened disk parts 14 'together with the bracket arms 3' form an approximately cylindrical air duct which, depending on the cooling requirements, can rise more or less upwards over the laminated core.
