Description

Anlage zur Gebrauchsmusteranmeldung . Wechselstrommaschine Die Neuerung bezieht sich auf eine Wechselstrommaschine mit elektro- magnetischer Erregung, insbesondere Stromerzeuger für Fahrzeuge, bei der das Ankersystem und das Erregersystem feststehend und konzentrisch ineinanderliegend gleichachsig zu einem zwischen ihnen umlaufenden, Klauenpole aufweisenden Kraftlinienleitstück angeordnet sind und die mit einem Lüfter versehen ist. Attachment to Utility model registration . AC machine The innovation relates to an alternating current machine with electric magnetic excitation, in particular power generators for vehicles, in which the armature system and the excitation system are stationary and concentrically one inside the other, equiaxed to a force line guide piece rotating between them and having claw poles and which is provided with a fan.

Bei Wechselstrommaschinen dieser Art besteht die Schwierigkeit, die Kühlluft an den innerhalb des Kraftlinienleitstücks sitzenden Anker heranzubringen « Gemäss der Neuerung wird dies dadurch erreicht, dass das innerhalb des LeitstUckes sitzende Ankersystem an mehreren mit seitlichem Abstand voneinander in das Innere der Maschine hineinragende Vorsprünge eines das Gehäuse abdeckenden, mit Durchbrüchen versehenen Schildes zentriert und befestigt ist und Längskanäle aufweist, die in Deckung mit den LUcken zwischen den Vorsprüngen liegen. Es zeigt : Fig. 1 eine Wechselstrommaschine mit feststehendem Anker-und Feldsystem im Längsschnitt und Fig. 2 einen Schnitt nach der Linie II-II der Fig. l.With AC machines of this type there is the difficulty of bringing the cooling air to the armature sitting inside the force line guide piece. According to the innovation, this is achieved by the armature system sitting inside the guide piece on several projections protruding laterally into the interior of the machine into the interior of the machine covering, perforated shield is centered and fastened and has longitudinal channels that are in alignment with the LUcken between the projections. It shows : Fig. 1 shows an alternating current machine with a fixed Anchor and field system in longitudinal section and FIG. 2 shows a section along the line II-II of FIG.

Die Wechselstrommaschine hat ein walzenförmiges Gehäuse 10 aus Eisen, in dem ein aus zwei Eisenringen 11 und 12 und einer Feldwicklung 13 bestehendes Erregersystem eingebaut ist. An jedem Ende des Gehäuses ist je ein Lagerschild 14 bzw. 15 mit Durchbrüchen 16 bzw. 17 befestigt. In diesen Schilden ist die Antriebswelle 18 der Wechselstrommaschine gelagert. Auf dem über das Lagerschild 15 vorstehenden Ende der Welle sitzt eine Keilriemenscheibe 19 mit Lüfterflügeln 20. An der Innenseite des Lagerschildes ist auf der Welle ein glockenförmiges Kraftlinienleitstück 21 aufgeteilte das im wesentlichen aus zwei koaxial angeordneten Ringen 22 und 23 besteht, die an den einander zugekehrten Seiten Polfinger 24 bzw. 25 haben die gegenseitig ineinandergreifen. Die Ringe werden von einer Tragscheibe 26 getragen, die mehrere Locher 27 für den Durchtritt von Luft hat. Innerhalb des Leitstückes befindet sich ein ringförmiger Blechkörper 28, der in Nuten die Ankerwicklung 29 trägt. Das Lagerschild 14 hat mehrere mit seitlichem Abstand voneinander in das Innere der Maschine hineinragende Vorsprünge 30, an denen der Ankerblechkörper zentriert und mit Schrauben 31 befestigt ist. Diese Vorsprünge sind an eine Lagernabe 32 des Lagerschildes 14 angegossen, in der die Antriebswelle gelagert ist. Der Blechkörper hat Längskanäle 33, die in Deckung mit den Lücken 34 zwischen den Vorsprüngen liegen.The alternator has a barrel-shaped housing 10 made of iron, in which one consisting of two iron rings 11 and 12 and a field winding 13 Excitation system is built in. At each end of the housing there is a bearing plate 14 or 15 fastened with openings 16 and 17, respectively. In these shields is the drive shaft 18 of the alternator stored. On the protruding over the bearing plate 15 At the end of the shaft there is a V-belt pulley 19 with fan blades 20. On the inside of the end shield is a bell-shaped force line guide piece 21 on the shaft divided, which essentially consists of two coaxially arranged rings 22 and 23, the pole fingers 24 and 25 on the mutually facing sides have each other interlock. The rings are carried by a support disk 26, the several Has hole 27 for the passage of air. Inside the guide piece is located an annular sheet metal body 28 which carries the armature winding 29 in grooves. The bearing shield 14 has several protruding into the interior of the machine at a lateral distance from one another Projections 30 on which the sheet metal anchor body is centered and fastened with screws 31 is. These projections are cast onto a bearing hub 32 of the bearing plate 14, in which the drive shaft is mounted. The sheet metal body has longitudinal channels 33, which in Coincide with the gaps 34 lie between the projections.
