Abstract

The bearing hubs(9, 10) integral with the housing end plates(7, 8) extend inwards. At the driving end of the axle space is provided by leaving the conductor loops(13) of the rotor(1) unsupported. This provides for a recess in the rotor body into which the bearing hub with its bearing(11) protrudes. Similarly, at the commutator end, the hub(10) of the right hand end plate(8) protrudes inwards and clears a suitably recessed insulating core(5) which carries the commutator strip ring(4).

Description

Elektrische Maschine mit einem eine Wicklung und einenElectrical machine with one winding and one

Kommutator aufweisenden Läufer Die Erfindung betrifft eine elektrische Maschine mit einem eine Wicklung und einen Kommutator aufweisenden Läufer, bei der die Lager für den Läufer jeweils in einer Nabe von antriebs- und bürstenseitig am Maschinengehäuse befestigten Lagerschilden angeordnet sind und auf der Läuferwelle ein die Kommutatorlamellen tragender Isolierstoffring angebracht ist.The invention relates to an electrical rotor having a commutator Machine with a rotor having a winding and a commutator, in which the bearings for the rotor are each in a hub on the drive and brush sides Machine housing attached end shields are arranged and on the rotor shaft a ring of insulating material carrying the commutator bars is attached.

Bei bekannten Maschinen dieser Art sind die Lagerschilde so ausgebildet, daß die Lager axial vor dem Wickelkopf der Läuferwicklung und dem Kommutator liegen.In known machines of this type, the end shields are designed so that the bearings are axially in front of the end winding of the rotor winding and the commutator.

Der Erfindung liegt die Aufgabe zugrunde, eine elektrische Maschine der eingangs beschriebenen Art mit einer wesentlich kürzeren axialen Baulänge zu schaffen.The invention is based on the object of an electrical machine of the type described at the outset with a significantly shorter overall axial length create.

Die Lösung der gestellten Aufgabe gelingt nach der Erfindung dadurch, daß die Naben an den beiden Lagerschilden nach innen vorstehend ausgebildet sind, wobei die Nabe des antriebsseitigen Lagerschildes in axialer Richtung unter den Wickelkopf der Läuferwicklung und die Nabe des bürstenseitigen Lagerschildes in eine axiale Ausnehmung des Isolierstoffringes ragt.The object is achieved according to the invention in that that the hubs on the two end shields protrude inwards, whereby the hub of the drive end shield in the axial direction under the end winding of the rotor winding and the hub of the bearing plate on the brush side protrudes into an axial recess of the insulating ring.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird der Anmeldungsgegenstand nachfolgend näher beschrieben.Based on an embodiment shown in the drawing the subject of the application is described in more detail below.

Mit 1 ist der mit einer Läuferwicklung 2 versehene Läufer einer elektrischen Maschine bezeichnet. Auf der Welle 3 des Läufers ist ein die Kommutatorlamellen 4 tragender Isolierstoffring 5 angeordnet. An dem Maschinengehäuse 6 ist ein antriebsseitiger Lagerschild 7 und ein bürstenseitiger Lagerschild 8 befestigt. Der antriebsseitige Lagerschild 7 weist eine nach innen gerichtete Nabe 9 und der bürstenseitige Lagerschild 8 eine ebenfalls nach innen gerichtete Nabe 10 auf. In den Naben 9 und 10 sind zwei Kugellager 11 und 12 zur Lagerung der Läuferwelle 3 angeordnet.1 with the rotor provided with a rotor winding 2 is an electrical rotor Machine called. The commutator bars are on shaft 3 of the rotor 4 supporting insulating ring 5 arranged. On the machine housing 6 is a drive-side End plate 7 and a brush-side end plate 8 attached. The drive-side End shield 7 has an inwardly directed hub 9 and the brush-side end shield 8 also has an inwardly directed hub 10. In the hubs 9 and 10 are two Ball bearings 11 and 12 for supporting the rotor shaft 3 are arranged.

Der Außendurchmesser der Nabe 9 des antriebsseitigen Lagerschildes 7 ist kleiner als der Innendurchmesser des Wickelkopfes 13 der Läuferwicklung 2. Damit kann die Nabe 9 in axialer Richtung unter den Wickelkopf 13 ragen, so daß der antriebsseitige Lagerschild 7 näher an den Wickelkopf 13 heranrückt. Damit auch der bürstenseitige Lagerschild 8 näher an den Kommutator herangerückt werden kann, ist in dem Isolierstoffring 5 eine axiale Ausnehmung 14 vorgesehen, in die die Nabe 10 des bürstenseitigen Lagerschildes 8 ragt. Die beiden Lagerschilde 7 und 8 können somit bis auf einen durch die Maschinenspannung vorgegebenen Sicherheitsabstand an den Wickelkopf 13 bzw. an den Kommutator herangerückt werden. Hierdurch wird eine wesentliche Verkürzung der axialen Baulänge der Maschine erreicht.The outer diameter of the hub 9 of the drive-side end shield 7 is smaller than the inner diameter of the end winding 13 of the rotor winding 2. So that the hub 9 can protrude in the axial direction under the end winding 13, so that the end shield 7 on the drive side moves closer to the end winding 13. So too the bearing plate 8 on the brush side can be moved closer to the commutator, an axial recess 14 is provided in the insulating ring 5, into which the hub 10 of the brush-side bearing plate 8 protrudes. The two end shields 7 and 8 can thus up to a safety distance specified by the machine voltage be moved to the end winding 13 or to the commutator. This will a significant reduction in the overall axial length of the machine is achieved.
