Description

Die Erfindung bezieht sich -auf einen Kommutatordruckring für elektrische Maschinen, der als Lüfter ausgebildet ist. Ihr liegt die Aufgabe zugrunde, den Zusammenbau der Maschine leichter zu gestalten.The invention relates to a commutator pressure ring for electrical Machine designed as a fan. Its underlying task is the assembly make the machine easier.

Erfindungsgemäß sind die Lüfterflügel zwischen der einen Stirnseite des Druckringes und einer vorzugsweise mit Tariernut versehenen Deckscheibe angeordnet.According to the invention, the fan blades are between the one end face of the pressure ring and a cover plate preferably provided with a taring groove.

Ein Ausführungsbeispiel der Erfindung gibt die Zeichnung wieder. Der Kommutatordruckring i besteht zusammen mit Lüfterflügeln 2 und einer mit Tariernut 3 versehenen Deckscheibe q. aus einem zusammenhängenden Werkstück, insbesondere Gußstück. Die Spannschrauben 5 sind durch Ausbauchungen der Lüfterflügel hindurchgeführt. Sie können aber auch zwischen den Lüfterflügeln angeordnet sein, oder es kann die Deckscheibe Löcher haben, durch die die an der Druckringstirnseite aufsitzenden Schraubenköpfe mit dem Schlüssel erreicht werden können.The drawing shows an embodiment of the invention. Of the Commutator pressure ring i consists of fan blades 2 and one with a taring groove 3 provided cover plate q. from a coherent workpiece, in particular Casting. The clamping screws 5 are passed through bulges of the fan blades. But you can also be arranged between the fan blades, or it can Cover disk have holes through which the seated on the pressure ring face Screw heads can be reached with the wrench.

Die Erfindung bietet den Vorteil, daß der mechanisch stark beanspruchte Druckring durch die Flügel 2 und die Deckscheibe 4. versteift wird, er kann aber schwächer bemessen werden. als wenn die Flügel und die Deckscheibe nicht vorhanden wären. Außerdem kommt der unmittelbar am Druckring vorbeigeführte Luftstrom der Kommutatorkühlung zugute.The invention offers the advantage that the mechanically highly stressed Pressure ring is stiffened by the wing 2 and the cover plate 4, but it can be rated weaker. as if the wings and the cover disk were not present would be. In addition, the air flow that is passed directly past the pressure ring comes from the Commutator cooling benefit.
