Description

Elektrische Maschine mit angebautem Lüfter Bei bekannten elektrischen Maschinen mit besonderem Lüfteraggregat ist dieses Aggregat entweder an der einen Stirnseite der Maschine mit zur Maschinenachse koaxialer Aggregatachse oder auf dem Gehäuserücken mit zur Maschinenachse paralleler Achse angeordnet.Electric machine with built-on fan In known electric For machines with a special fan unit, this unit is either on one side Front side of the machine with the unit axis coaxial with the machine axis or on the back of the housing arranged with the axis parallel to the machine axis.

Die Erfindung gibt einen besonders raumsparenden Anbau des Aggregates für elektrische Maschinen mit Stromabnehmern, insbesondere für elektrische Gleichstrommaschinen für aussetzenden Betrieb an. Erfindungsgemäß ist die Achse des Lüfteraggregates etwa senkrecht zur Maschinenachse gerichtet und ragt das Aggregat mit seinem Lüfterteil in den Stromabnehmerraum der Maschine hinein.The invention provides a particularly space-saving attachment of the unit for electrical machines with pantographs, in particular for electrical DC machines for intermittent operation. According to the invention is the axis of the fan assembly directed approximately perpendicular to the machine axis and protrudes the unit with its fan part into the pantograph compartment of the machine.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Sie zeigt den kommutatorseitigen Teil einer elektrischen Maschine im Längsschnitt.An exemplary embodiment of the invention is shown in the drawing. It shows the commutator-side part of an electrical machine in a longitudinal section.

An das zylindrische Maschinengehäuse 1 ist der Lagerschild 2 angebaut, der das bürstenseitige Lager 3 trägt, in dem die Maschinenwelle 4 gelagert ist. Auf der Welle 4 sitzt der Kommutator 5. Auf dem Gehäuserücken ist ein Lüfteraggregat 6 mit zur Maschinenachse senkrecht gerichteter Aggregatachse angeordnet und mittels- eines zylindrischen Haltestückes 7 befestigt. Der Lüfter 8 des Aggregates ragt in den Kommutatorraum 9 des Maschinengehäuses hinein. Der Antriebsmotor 10 des Aggregates ist mit den Klemmen 11 der Maschine in einem gemeinsamen Kasten 12 angeordnet.The end shield 2 is attached to the cylindrical machine housing 1, which carries the brush-side bearing 3 in which the machine shaft 4 is mounted. The commutator 5 sits on the shaft 4. A fan assembly is located on the back of the housing 6 arranged with the unit axis perpendicular to the machine axis and a cylindrical holding piece 7 attached. The fan 8 of the unit protrudes into into the commutator space 9 of the machine housing. The drive motor 10 of the unit is arranged in a common box 12 with the terminals 11 of the machine.

Mit der Erfindung ist nicht nur der sonst freie Gehäuseraum am Stromabnehmer gut ausgenutzt, sondern auch der Lüfter möglichst nahe an die aktiven Teile der Maschine herangebracht. Da nur ein Teil des Lüfteraggregates aus dem Motorgehäuse herausragt, kann es ohne Schwierigkeiten mit den Anschlußklemmen in einem gemeinsamen Kasten untergebracht und können die äußeren Abmessungen der Maschine trotz des zusätzlichen Lüfteraggregates klein gehalten werden.With the invention, not only is the otherwise free housing space on the pantograph well used but also the fan as close as possible to the active parts of the Machine brought up. Because only part of the fan unit comes from the motor housing protrudes, it can be easily connected to the terminals in a joint Box housed and can accommodate the external dimensions of the machine despite the additional Fan assembly can be kept small.
