Description

Die Erfindung bezieht sich auf Stromwender, insbesondere für solche elektrischen Maschinen, deren Anker mit einer Stabwicklung versehen ist. Bisher war es üblich, in die Fahnen der Stromwendersteg^: Nuten einzufräsen, in die die Enden der Ankerwicklung eingelegt werden. Ferner hax man bekanntlich in Schlitze der Fahnen Zwingen aus Blechstreifen eingelötet, die·die·.Wicklungsenden "10. umfassen. Ebenso ist es bekannt, jeden Steg aus zwei Lamellen zusammenzusetzen, die je einen sich radial nach außen hin verjüngenden Lappen als Fahne haben. Zwischen diese Lappen werden die zu dem Steg gehörigen, if Ankerdrahtenden eingelegt und dann die beiden Lappenenden zusammengebogen. Bei diesen AusführuBgsarten>.ist nach dem Einlegen der Drahtenden noch: ein weiterer Arbeitsgang nötig, oder es besteht der Nachteil, daß die Drähte kernen wirksamen Halt finden, wenn sie bei hoher Drehzahl und starker Erwärmung der Maschine enüötet und nach außen gepreßt werden. Zwecks Vermeidung dieser Nachteile werden die Lamellen gemäß der Erfindung >on vornherein mit Nuten versehen, und zwar so, daß diese beim Zusammensetzen der Lamellenpaare einen ganz oder nahezu ganz geschlossenen Raum bilden, in dem die Wicklungsenden radial nach außen hin gehalten werden.The invention relates to commutators, especially for those electrical machines whose armature is provided with a bar winding is. Up until now it was customary to mill grooves into the flags of the commutator web which the ends of the armature winding are inserted. Furthermore, as is well known, one hax in Slits of the flags clamps made of sheet metal strips soldered into the · the · .winding ends "10. Include. Likewise, it is known to include every web composed of two lamellas, each one tapering radially outwards Have rag as a flag. Between these flaps are those belonging to the bridge, if anchor wire ends inserted and then the two The ends of the lobes are bent together. With these types of execution> .is after insertion the wire ends: another work step necessary, or there is the disadvantage that the wires find effective support, if it unsoldered at high speed and strong heating of the machine and after be pressed outside. In order to avoid these disadvantages, the slats are according to of the invention> on from the outset provided with grooves, in such a way that they are put together of the pairs of lamellas form a completely or almost completely closed space, in which the winding ends are held radially outwards.

In der Zeichnung sind zwei AusführungS'· beispiele' des Erfindungsgegenstandes" darge-. stellt. Es zeigt:In the drawing there are two versions Examples' of the subject matter of the invention ". It shows:

Die Abb. 1 zeigt die übliche Befestigung von Sttomwenderstegien mittels 'eines schwalbenschwanzförmigen Fußes der Stiege, der von einem Keilring und einer Keilnab e gehalten wird. Abb. 2 zeigt die Unterteilung derartiger Stege ifL je zwei Lamellen α und b, von denen eine in Abb. 3 gesondert dargestellt ist. Diese Lamellen werden in üblicher Weise aus , Profilstäben aus gezogenem Kupfer oder ähnlichem Metall ausgestanzt. Erfindungsgemäß besitzen die Lamellen zur Aufnahme der Enden der Ankerwicklungsstäbec,d Nutene, die beim Ziehen der Profilstäbe in diese eingearbeitet worden /sind und die beim Zusammensetzen der Lamellenpaare einen geschlossenen Raum bilden, in dem die Wicklungsenden radial-nach außen hin gehalten werden. Die beim Betriebe radial nach außen hin gerichtete Druckkraft der Wicklungsenden wird von den äußeren Wandungen der Nuten aufgemommeri..Fig. 3 a section of a lamella, Fig. 4 the other embodiment. Fig. 1 shows the usual fastening of Sttomwenderstegien by means of a dovetail-shaped foot of the stairs, which is held by a wedge ring and a wedge hub. Fig. 2 shows the subdivision of such webs ifL two lamellas α and b, one of which is shown separately in Fig. 3. These lamellas are punched in the usual way from profile rods made of drawn copper or similar metal. According to the invention, the lamellae for receiving the ends of the armature winding rods, d grooves e, which were / have been incorporated into them when the profile rods are pulled and which form a closed space when the lamella pairs are assembled, in which the winding ends are held radially outwards. The compressive force of the winding ends, which is directed radially outwards during operation, is absorbed by the outer walls of the slots.

Bei der zweiten Ausführungsform (Abb. 4) besteht jeder Stromwendersteg aus drei Lamellen /, g und h. Die Fahnen i der beiden äußeren Lamellen besitzen hierbei je ein Querstück k, das im Betriebe die Druckkraft der Wicklungsenden aufnimmt. Der zwischen den Querstücken k und den mittleren Lamellen h liegende, zur Aufnahme der Wicklungsenden dienende Raum ist mit m bezeichnet.In the second embodiment (Fig. 4) each commutator web consists of three lamellas /, g and h. The lugs i of the two outer lamellas each have a cross piece k, which absorbs the compressive force of the winding ends when in operation. The space between the cross pieces k and the central lamellas h and used to accommodate the winding ends is denoted by m.
