Description

Die Erfindung bietriffteine S.pulens.tütze für elektrische Maschinen, insbesondere für Gleichstrommaschinen mit Haupt- und Wendepol.The invention concerns a coil support for electrical machines, especially for DC machines with main and reversing poles.

Um :ein Aufblättern der Wicklungen in den zwischen einer Spule und dem Gehäuse befindlichen Zwischenraum zu vermeiden, verwendet man bekanntlich diesen Raumausfüllende Stützkörper. Diese Stützkörpter liegen an der unbearbeiteten Innenseite der Gehäusewand ;an. Diese Stützkörper haben den Nachbeil, daß infolge der Ungenauigkeit der unbearbeiteten Innenwand des Gehäuses ein exaktes Liegen der Spulen nicht erreicht wird, falls man nicht durch besondere Arbeiten jede Stützte einzeln besonders sorgfältig einsetzt. Diese besondere Einarbeitung der Stützen aber hat den Nachteil, daß erhebliche Kosten und Zeitverluste bei der Herstellung der Maschinen entstehen.To: a peeling of the windings in between a coil and To avoid the gap located in the housing, this is known to be used Space-filling support bodies. These support bodies are on the unprocessed inside the housing wall; on. These support bodies have the disadvantage that as a result of the inaccuracy the unprocessed inner wall of the housing does not allow the coils to lie exactly becomes, if one does not carry out special work, each and every one of the supports is particularly careful begins. This particular incorporation of the supports has the disadvantage that it is considerable Costs and time losses arise in the manufacture of the machines.

Gemäß, der vorliegenden Erfindung werden Spulenstützen dadurch wesentlich `verbessert und vereinfacht, daß man @an den Stützten nach Art. eines Schemels Beine oder Füße vorsieht, die maßhaltig in den ausgearbeiteten Sitz des: Pols eingreifen. BeispiAsweise können. die Beine oder Füße auf dem axial neben: den Stirnflächen 'der Pole liegenden Teil des, Polsitzes, der als Nut oder als Fläche ist, ,angreifen. -.-In der Zeichnung ist ein Ausführungsbieispiel dargesüeUt.In accordance with the present invention, this makes spool supports essential `Improved and simplified that one @supported legs like a stool or provides feet that intervene true to size in the elaborated seat of the: Pole. For example, you can. the legs or feet on the axially next to: the end faces 'Attack the part of the pole seat, which is located as a groove or as a surface, which is located on the pole. -.- An exemplary embodiment is shown in the drawing.

Fig. i zeigt (einen Schnitt durch einen Teil einer elektrischen Maschine, und Fig. z zeigt ,eine Draufsicht auf eine Spulenstütxe. In .Fig. i.-ist bei i eine bekannte Spuienstütze 2-. daxgesüellt, :die an :der unbearbeiteten Innenseite des Gehäustes 3 bei ¢ anliegt. Infolge der rauben Innen.-leite liegt die Stütze a bei 5 bereits, nicht n-ehr an. Anders hingegen bei dem Pol 6. Hier `hat -,die Spulenstütze 7 durch Aufspreizen an dem zur Aufnahme des Pols_ dienenden -Ausschnitt Stützen ä erhalten, die in die ausgearbeitete Nut g, in: der auch der Pol 6 sitzt, eingreifen. Auf .diese Weise wurde Leine exakte Lage der Stützte 7 erreicht.Fig. I shows (a section through part of an electrical machine, and Fig. z shows a plan view of a bobbin case. In .Fig. i.- at i is a well-known spool support 2-. daxgesüellt,: die on: the unprocessed inside of the Housing 3 is at ¢. As a result of the rough inner guide, support a is included 5 already, not n-more an. On the other hand, it is different with pole 6. Here `has -, the coil support 7 by spreading it open on the cutout supports serving to accommodate the Pols_ ä obtained, which engage in the machined groove g, in which the pole 6 is also seated. In this way the exact position of the support 7 was achieved on the line.

Wie aus Fig. 2 ersichtlich, besteht die Stütze aus einem Blechstreifen i o, an dessen Ausnehmung i i Fahnen i a vorgesehen sind. Diese Fahnen 12 werden hochgebogen und dienen dann als Beine oder Füße des Stützbleches i o.As can be seen from Fig. 2, the support consists of a sheet metal strip i o, on whose recess i i flags i a are provided. These flags are 12 bent up and then serve as legs or feet of the support plate i o.
