Description

Die Erfindung betrifft eine- elektrische Maschine mit Kühlrippen und Luftkühlung.The invention relates to an electrical machine with cooling fins and Air cooling.

Es sind bereits elektrische Maschinen bekanntgeworden, deren Gehäuse mit Kühlrippen versehen sind, die einem Kühlluftstrom ausgesetzt sind. Die bekannten elektrischen Maschinen haben den Nachteil, daß idie aus Metallguß bestehenden Gehäuse verhältnismäßig ischwer sind und ziemlich viel Metall (benötigen.There are already known electrical machines, the housing are provided with cooling fins that are exposed to a flow of cooling air. The known electrical machines have the disadvantage that i the cast metal housing are relatively heavy and require a lot of metal.

Gemäß der vorliegenden Erfindung werden nun elektrischeMaschinen der vorerwähntenArt wesentlich verbessert und vereinfacht, wenn man die Kühlrippen hei aus Blech bestehenden Maschinengehäusen durch Aufschlitzen des Blechgehäuses bildet. Der das Maschinengehäuse umgebende ruftführungsblechmantel kann ebenfalils durch Aufschlitzen mit nach innen weisenden. Rippen versehen sein. Man kann den Luftführungsblechmantel mit einem besonderen Schutzzylinder versehen. Die durch das Aufschlitzen erzielten Fenster können auch nur teilweise geöffnet und teilweise abgedeckt bzw. geschlossen sein. Die Länge der beim Aufschlitzen entstehenden Schlitze ist höchstens so. groß wie .die Breite des betreffenden Blechpaketes .der elektrischen Maschine.In accordance with the present invention, electrical machines now become the The aforementioned type is significantly improved and simplified if the cooling fins are hot Machine housings made of sheet metal are formed by slitting open the sheet metal housing. The call guide sheet metal jacket surrounding the machine housing can also pass through Slit open with inward facing. Be provided with ribs. You can use the air baffle jacket provided with a special protective cylinder. The ones obtained by slitting Windows can also only be partially opened and partially covered or closed be. The length of the slits resulting from the slitting is at most like this. great like .the width of the laminated core concerned .the electrical machine.

- In der Zeichnung sind einige Ausführungsbei-,spiele dargestellt.- In the drawing some examples are shown, games.

Fig. i zeigt einen Teil eines Längsschnittes durch eine elektrische Maschine; Fig.2 und 3 .zeigen Draufsichten auf den Gehäusemantel und Fig. q. eine andere Ausführungsform im Schnitt senkrecht zur Maschinenachse.Fig. I shows part of a longitudinal section through an electrical Machine; Fig. 2 and 3. Show plan views of the housing shell and Fig. Q. one Another embodiment in section perpendicular to the machine axis.

Der Ständer 2 der elektrischen Maschine i hat das Blechgehäuse 3; aus welchem die durch Aufschlitzen nach den Linien 4 gewonnenen Rippen 5 herausragen. Die Rippen 5 können zur Abstützung gegenüber Odem Luftleitblech 6 dienen. Der in Richtung des Pfeiles 7--eintretend--Kühlluftstrom streicht an den Rippen 5 vorbei und bewirkt so eine außerordentlich wirksame Kühlung der elektrischen Maschine.The stator 2 of the electrical machine i has the sheet metal housing 3; from which the ribs 5 obtained by slitting according to the lines 4 protrude. The ribs 5 can serve as a support against the air baffle 6. The in Direction of arrow 7 - entering - cooling air flow sweeps past the ribs 5 and thus causes an extremely effective cooling of the electrical machine.

Wie aus FinG. 4 ersichtlich, greifen in die zwischen den Rippen 5 befindlichen Zwischenräume Rippen 8 des L,üftleitbleches g. Die durch das Einbiegen der Rippen 8 verursachten Fenster lo sind mittels des außenliegenden Sdhutzzylirnders i i abgedeckt. Wie man aus den Abbildungen ersieht, befindet sich der Bereichder Rippen innerhalb der Blechpaketbreite bzw. -länge. Wie aus Fig. 2 hervorging, werden adie Rippen im angerollten Zustand des Blechmantels ausgeschnitten und nach Fig. 3 nach oben gebogen, so daß Fenster entstehen, .deren Öffnungen durch .den Rücken des Ständerblechpaketes a abgedeckt sind.As from FinG. 4 can be seen, engage in the between the ribs 5 located interstices ribs 8 of the L, üftleitbleches g. The one by bending the ribs 8 caused windows lo are by means of the outer Sdhutzzylirnders i i covered. As can be seen from the figures, the area is the Ribs within the sheet stack width or length. As emerged from Fig. 2, will a cut out the ribs in the rolled-on state of the sheet metal jacket and, as shown in Fig. 3 bent upwards, so that windows emerge, .their openings through .the back of the stator core a are covered.
