Description

  

  Künstlich gekühlte, elektische Maschine.    Die vorliegende Erfindung bezieht sich  auf künstlich gekühlte, elektrische Maschinen,  bei denen das Gehäuse mit einem Mantel  umhüllt ist zwecks Bildung eines Zwischen  raumes für den Durchgang des Kühlmittels.  Wird zum Beispiel ein derartig ausgebildeter,  mit Durchzugsluft gekühlter Motor für den  Antrieb von Holzbearbeitungsmaschinen oder  Textilmaschinen benützt, so kann sich im  erwähnten Zwischenraum Staub ansammeln,  insbesondere auch dann, wenn im Zwischen  raum noch Kühlrippen eingesetzt sind. Um  nun diesen Zwischenraum bequem reinigen  zu können, ist erfindungsgemäss der Mantel  des Zwischenraumes so eingerichtet, dass er  sich öffnen lässt, zum Beispiel durch Auf  klappen, Verschwenken oder Verschieben des  selben.  



  Die beiliegende Zeichnung zeigt drei Aus  führungsbeispiele des Erfindungsgegenstandes.  Fig.1 zeigt im Längsschnitt einen Teil einer  elektrischen Maschine mit dem Gehäuse 1, dem  dasselbe umhüllenden Mantel 2 aus Blech  und dem dazwischen liegenden Raum 3, durch    welchen Luft vom Ventilator 4 her gedrückt  wird.  



  Wie in Fig. 2 angegeben ist, besteht der  Blechzylinder 2 der Fig. 1 aus zwei Hälften,  a und b, mit einem Scharnier 5, so dass der  Zylinder 2 aufgeklappt und dadurch der  Zwischenraum 3 freigelegt werden kann.  



  Die beiden Halbzylinder a, b können auch  so eingerichtet sein, dass sie übereinander  verstellbar sind, sei es gemäss Fig. 3, wo  der eine Halbzylinder über den andern ge  schwenkt werden kann, oder sei es teleskop  artig nach Fig. 4.



  Artificially cooled, electrical machine. The present invention relates to artificially cooled electrical machines, in which the housing is covered with a jacket in order to form an intermediate space for the passage of the coolant. If, for example, a motor of this type, cooled with airflow, is used to drive woodworking machines or textile machines, dust can collect in the space mentioned, especially if cooling fins are still used in the space. In order to be able to clean this intermediate space easily, according to the invention the jacket of the intermediate space is set up in such a way that it can be opened, for example by folding it open, pivoting or moving it.



  The accompanying drawing shows three exemplary embodiments of the subject invention. 1 shows, in longitudinal section, part of an electrical machine with the housing 1, the same enveloping jacket 2 made of sheet metal and the space 3 in between, through which air is pressed by the fan 4.



  As indicated in FIG. 2, the sheet metal cylinder 2 of FIG. 1 consists of two halves, a and b, with a hinge 5, so that the cylinder 2 can be opened and the space 3 can be exposed.



  The two half cylinders a, b can also be set up so that they can be adjusted one above the other, be it according to FIG. 3, where one half cylinder can be pivoted over the other, or be it telescopically according to FIG. 4.
