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
