Description

Um elektrische Maschinen möglichst hoch ausnutzen zu können, ist ees -erforderlich, die Wicklungen und das aktive Eisen zu kühlen. Dies kann durch Fremdbelüftung mittels zusätzlicher Lüfter oder bei umlaufenden. Maschinen durch Eigenbelüftung mittels ;an- dem umlaufenden Teil angebrachter Lüfberflügel geschehen. Die Kühlluft wird bei solchen Maschinen mit Eigenbelüftung in der Regel von der Seite über die Wickelköpfe gefördert und zwischen dem. Ständerblechpaket und dem Gehäusie zu in diesem angebrachten Austrittsöffnungen geführt. Um dabei eine möglichst wirksame Kühlung auch des Blechpaketes zu erzielen, wird Birne möglichst tangentiale Luftfüh=g angestrebt. Zu diesem Zweck müssen die das Blechpaket tragenden axial - verkaufenden Gehäuserippen mit Durchbruchsöffnungen versehen werden. Dies bedingt die Herstellung komplizierter Gehäusemodelle und stellt eine Erschwerung der Fertigung dar.In order to be able to utilize electrical machines as high as possible, ees -required to cool the windings and the active iron. This can be done by external ventilation by means of an additional fan or with rotating. Machines through self-ventilation by means of fan blades attached to the circumferential part. The cooling air in such machines with self-ventilation is usually from the side over the End winding promoted and between the. Stator core and the housing to in this attached outlet openings out. In order to be as effective as possible To achieve cooling of the laminated core, pear is as tangential as possible aimed at. For this purpose, the axially - selling ones carrying the laminated core must Housing ribs are provided with openings. This requires the production complicated housing models and makes production more difficult.

Durch die Erfindung werden umlaufende elektrische Maschinen geschaffen, bei denen tdie Herstellung Blas Gehäuses wesentlich vemeinfacht wird, ohne .daß dabei die Wirksamkeit der Kühlung beeinträchtigt wird. Die Erfindung besteht darin, daß die das Ständerblechpaket tragenden Rippeln: des Gehäuses. ;abwechselnd von beiden Seiten nur bis etwa in die Mitte des Gehäuses reichen. Die beiderseits angeordneten Gehäuserippen sind also in Umfangsrichtung gegeneinander versetzt, wodurch erreicht wird; daß die von beeiden Seiten zugeführte Kühlluft in: dendurch die Gehäuserippen gebildeten Luftkanälen in Schlangenlinien mit teilweise tangentvalier Richtung :strömen muß.The invention creates rotating electrical machines, in which the production of the blower housing is considerably simplified without .that the effectiveness of the cooling is impaired. The invention consists in that the corrugations carrying the stator core: of the housing. ; alternating from both sides only reach roughly into the middle of the housing. The ones arranged on both sides Housing ribs are therefore offset from one another in the circumferential direction, which is achieved will; that the cooling air supplied from both sides enters through the housing ribs air channels formed in serpentine lines with partially tangential direction: flow got to.

Zur Erläuterung der Erfindung ist in der Zeichnung ;als. Ausführungsbeispiel ein. zwei Ansichten (Feg. i und 2) Bein Gehäusie für Leinen Elektnotmtobor dargestellt, wobei alle für :die Erfindung unwesentlichen Teile fortgelassen bzw. nur angedeutet sind. Das Gehäuse i besitzt in bekannter Weise am inneren Umfang axiale Rippen 2, die das Ständerblechpaket 3 tragen. Gemäß der Erfindung sind nun diesle Rippen 2 nicht über die ganze Länge des Gehäuses durchgeführt, sondern reichen jewieils nur etwa bis in die Gehäusiemitte. Dabei sind die an den beiden Seiten des Gehäuses angeordneten Rippen 2' bzW. 2" in Umfangsrichtung gegeneinander versetzt, so tdaß jeweils von beiden Seiten angeordnete Rippenmiteinander abwechseln. Dadurch wird die von dien Seiten über die Wickelköpfe geförderte Kühlluft gezwungen, wie durch Pfeile in der Zeichnung angedeutet ist, in Schlangenlinien durch die durch die Rippen 2 gebildeten Kanäle zu -strömten, um zu. den beispielsweise in der unteren Hälfte des Gehäuses angebrachbew Austrittsöffnungen q. zu gelangen.To explain the invention is in the drawing; as. Embodiment a. two views (Feg. i and 2) leg housing for lines Elektnotmtobor shown, all parts that are insignificant for: the invention are omitted or only indicated are. The housing i has in a known manner on the inner circumference axial ribs 2, which carry the stator core 3. According to the invention, these ribs are now 2 not carried out over the entire length of the housing, but only suffice in each case about to the middle of the case. There are those on both sides of the case arranged ribs 2 'or 2 "offset from one another in the circumferential direction, so that alternate ribs arranged from both sides with one another. This will the cooling air conveyed from the sides over the end windings is forced, as if through Arrows in the drawing are indicated in serpentine lines through the through the ribs 2 channels formed to -flow to to. the one in the lower half, for example the housing attached outlet openings q. to get.

Die Erfindung ist nicht ,auf -das dargestellte und beschriebene Ausführungsbeispiel beschränkt. Insbesiondene kann idie Zahl und Anordnung der Rippen hiervon je nach Bedarf abweichen. Auclh .die Labe der Austrittsöffnungen kann gegenüber dem Ausführungsbeispiel verändert und z. B. die Austrittsöffnung auch gegen das Eindringen von Spritzwasser geschützt werden. Die Erfindung ist für alle umlaufenden elektrischen Maschinen anwendbar, bei denen das Ständerblechpaket durch Rippen des Gehäuses gehalten wvixd.The invention is not limited to the illustrated and described exemplary embodiment. In particular, the number and arrangement of the ribs can vary depending on requirements. Auclh .die Labe of the outlet openings can be changed compared to the embodiment and z. B. the outlet opening can also be protected against the ingress of spray water. The invention can be used for all rotating electrical machines in which the stator core is held by ribs in the housing.
