Description

  

      Kühleinrichtung    für die     Zager    von Induktionsmotoren.    drei Schleifringe e in Umlauf versetzt wird.  Die Ventilationsflügel f können zugleich mit  zur Kühlung der Schleifringe e benutzt wer-     e     den.    Es ist bekannt, die Lager von Elektro  motoren mit Kühlrippen zu versehen und die  letzteren mittelst eines besonderen Hilfsven  tilators anzublasen. Nach der vorliegenden  Erfindung wird bei Induktionsmotoren mit       Schleifringanker    ein besonderer Ventilator  erspart, indem die     Ventilatorflügel    unmittel  bar an den dem Lager     benachbarten    Schleif  ring angesetzt werden.  



  Gemäss der Zeichnung wird innerhalb  des Lagerschildes a der auf dem Innenteil  des Lagerkörpers b sitzende Kühlrippen  körper c von der Kühlluft     bestrichen,    welche  von den     Ventilationsflügeln    f am äussern der



      Cooling device for the Zager of induction motors. three slip rings e is put into circulation. The ventilation blades f can also be used to cool the slip rings e. It is known to provide the bearings of electric motors with cooling fins and to blow the latter by means of a special auxiliary ventilators. According to the present invention, a special fan is spared in induction motors with slip ring armature in that the fan blades are attached immediacy bar to the slip ring adjacent to the bearing.



  According to the drawing, inside the end shield a, the cooling rib body c, which is seated on the inner part of the bearing body b, is swept by the cooling air, which from the ventilation blades f on the outside of the
