Description

Die Erfindung bezieht sich auf elektrische Gleichstrommaschinen mit fliegend angebauter Erregermaschine. Bei den bekannten Ausführungen sind Gehäuseteile der Erregermaschine an dem bürstenseitigen Lagerschild oder Lagerdeckel der Hauptmaschine befestigt. Der Innenraum der Erregermaschine ist bei diesen Aggregaten völlig abgeschlossen von dem Innenraum der Hauptmaschine.The invention relates to electrical DC machines with on-the-fly mounted exciter. In the known designs there are housing parts of the exciter on the bearing plate or bearing cover on the brush side of the main machine attached. The interior of the exciter is completely closed in these units from the interior of the main engine.

Die Erfindung hat die Aufgabe, die axiale Baulänge derartiger Maschinen zu verkürzen. Erfindungsgemäß ist das Gehäuse der Erregermaschine unmittelbar an dem Magnetgestell der Hauptmaschine angeflanscht, wobei der Flanschteil des Erregergehäuses mit radialen Lüftungsöffnungen für die Belüftung der Hauptmaschine versehen und der von dem Flanschteil gebildete Raum mit dem Raum der Hauptmaschine durch radiale Lüftungsöffnungen in einer das bürstenseitige Lager tragenden Zwischenwand verbunden ist.The invention has the task of reducing the overall axial length of such machines To shorten. According to the invention, the housing of the exciter is directly on flanged to the magnet frame of the main machine, the flange part of the exciter housing provided with radial ventilation openings for ventilation of the main engine and the space formed by the flange part with the space of the main engine by radial Ventilation openings connected in an intermediate wall carrying the brush-side bearing is.

Zweckmäßigerweise dient die Zwischenwand zugleich als Bürstenbrücke für die Bürstenstifte der Hauptmaschine.The partition wall expediently also serves as a brush bridge for the main machine's brush pens.

Die Erfindung soll an Hand des in der Zeichnung dargestellten Au-sfühnumgsbei,spiels näher erläutert werden. An dem Magnetgestell i der Gleichstrommaschine ist das Gehäuse der fliegend angebauten Erregermaschine mit dem Flanschteil 2, das mit dem Joch -3 aus einem Stück besteht, unmittelbar angeflanscht. Der Flanschteil 2 hat radiale Lufteintrittsöffnungen 4. Der von ihm gebildete Raum 5 ist mit dem Innenraum 6 der Hauptmaschine durch axiale Öffnungen 7 in der Zwischenwand 8 verbunden. In diese Zwischenwand ist das bürstenseitige Lager 9 eingebaut. Außerdem bildet die Wand auch die Bürstenbrücke für die Bürstenstifte io der Hauptmaschine. Um die Wand verdrehen zu können, sind Langlöcher i i vorgesehen. Die Kühlluft strömt in radialer Richtung an den Öffnungen 4 ein und wird dann in Pfeilrichtung durch die axialen Öffnungen 7 in den Innenraum der Hauptmaschine gesaugt.The invention is based on the Au-sfühnumgsbei, game shown in the drawing are explained in more detail. The housing is on the magnet frame i of the DC machine the overhung exciter with the flange part 2, the one with the yoke -3 consists of one piece, directly flanged. The flange part 2 has radial Air inlet openings 4. The space 5 formed by it is with the interior 6 of the Main machine connected by axial openings 7 in the intermediate wall 8. In these The brush-side bearing 9 is installed in the intermediate wall. It also forms the wall also the brush bridge for the brush pins io of the main machine. Twist around the wall to be able to, elongated holes i i are provided. The cooling air flows in a radial direction at the openings 4 and is then in the direction of the arrow through the axial openings 7 sucked into the interior of the main engine.

Durch die Zusammenlegung des Lufteintrittraumes mit dem Flanschraum der Erregermaschine wird die axiale Baulänge des Aggregats verkürzt. Da die radialen Lufteintrittsöffnungen nicht an dein festen Magnetgestell der Hauptmaschine, sondern an dem verdrehbaren Gehäuse der Erregermaschine angeordnet sind, ist freie Wahl in der Richtung des Lufteintritts und leichte Ant)assung an die verschiedenen Betriebsbedingungen möglich. Außerdem ist dadurch auch eine Verkürzung des Abstandes zwischen dem antriebsseitigen und dem bürstenseitigen Lager und damit eine Verminderung der Wellenbeanspruchung erzielt. Die Ausbildung der das Lager tragenden Zwischenwand als Bürstenbrücke ergibt eine weitere Verkürzung der axialen Baulänge.By merging the air inlet space with the flange space of the exciter, the overall axial length of the unit is shortened. Since the radial Air inlets are not on your fixed magnet frame of the main engine, but rather are arranged on the rotatable housing of the exciter is free choice in the direction of the air inlet and easy adaptation to the various operating conditions possible. In addition, this also shortens the distance between the drive-side and the bearing on the brush side and thus a reduction in the stress on the shaft achieved. The formation of the partition carrying the bearing as a brush bridge results a further reduction in the overall axial length.
