    Durchzugslüftung   für elektrische Maschinen in gemeinsamem Gehäuse. 



   Die Abblaseöffnungen der   Belüftungseinrichtungen   gekapselter elektrischer Maschinen, die in feuchten Räumen (z. B. auf Werten, auf Schiffen, im Freien oder in Werkstätten mit herumspritzendem Wasser) benutzt werden, sind meist derart angeordnet, dass der Luftstrom nach unten oder seitlich gerichtet ist. Diese Anordnung genügt, soweit sie die Maschinen gegen   Tropf wasser schützen   soll ; sie bringt jedoch eine Belästigung des bedienenden Personals durch die abgeblasene Kühlluft mit sich, da diese nach dem Auftreffen auf das Fundament zurückgeworfen wird und dann seitlich abströmt. In manchen Betriebsfällen, wie z. B. beim Arbeiten mit   Sshweissumformern,   kann das Blasen der Kühlluft zu einer Störung des Arbeitsvorganges, nämlich zum Ausblasen des Lichtbogens, führen.

   Die Erfindung beseitigt diese Nachteile. 



   Bei elektrischen Maschinen in gemeinsamem Gehäuse sind die spritzwasserdichten, an beiden Lagerschilden des Maschinenaggregats vorgesehenen Lüfterkammern oben mit   Luftaustrittsöffnungen

    Passage ventilation for electrical machines in a common housing.



   The vent openings of the ventilation devices of encapsulated electrical machines that are used in damp rooms (e.g. on valuables, on ships, outdoors or in workshops with water splashing around) are usually arranged in such a way that the air flow is directed downwards or to the side. This arrangement is sufficient insofar as it is intended to protect the machines against dripping water; However, it brings annoyance to the operating staff through the blown cooling air with it, since it is thrown back after hitting the foundation and then flows off to the side. In some operational cases, such as B. when working with welding converters, blowing the cooling air can lead to a disruption of the work process, namely to blowing out the arc.

   The invention overcomes these disadvantages.



   In the case of electrical machines in a common housing, the splash-proof fan chambers provided on both end shields of the machine unit are at the top with air outlet openings
 EMI1.1
 



  An exemplary embodiment of the invention is shown in the drawing.



  The machine housing 1 completely encloses a drive motor 2 and a dynamo
