Description

Ständer für elektrische Maschinen und Verfahren zu seiner Herstellung Stands for electrical machines and processes for their manufacture
Stand der TechnikState of the art
Die Erfindung geht aus von einem Ständer für elektrische Maschinen mit einer Stabwicklung nach dem Oberbegriff des Patentanspruchs 1 und von einem Verfahren zur Herstellung eines solchen Ständers.The invention relates to a stand for electrical machines with a bar winding according to the preamble of claim 1 and a method for producing such a stand.
Bei Drehstromgeneratoren, insbesondere Lichtmaschinen größerer Bauart zur Stromversorgung von Fahrzeugen ist der Ständer der Maschine mit einer mehrpoligen Drehstrom-Wellen- bzw. Schleifen¬ wicklung versehen, die aus einzelnen Leiterstäben in den Nuten des Ständerblechpaketes gebildet wird. Dabei werden die Leiterstäbe gemäß DE 37 04 780 AI"zunächst haarnadelförmig vorgebogen und die Schenkel werden im oberen Teil gegeneinander verschränkt, so daß sie in einem Spreizschritt über eine Polteilung des Ständerblechpaketes von der einen Stirnseite des Blechpaketes in dessen Nuten einge¬ steckt werden können. Auf der anderen Stirnseite werden die Enden der Leiterstäbe dann nochmals um eine Polteilung gegeneinander ver¬ schränkt, so daß die Stabenden paarweise übereinanderliegend zu einer Schleifen- bzw. Wellenwicklung miteinander verschweißt oder verlötet werden. Da bei derartigen Wicklungen zwischen den einzelnen Wicklungszügen einer jeden Phase sogenannte Zwischen- und Umkehr¬ verbindungen benötigt werden, hat man diese Zusatzschaltverbindungen bei Drehstrom-Lichtmaschinen bislang auf einer Seite des Stators an den Stabenden in Form von Zusatzschaltbügeln angeordnet, die mit den jeweiligen Leiterstabenden in besonderen, zusätzlichen Arbeitsgängen manuell verschweißt wurden.In the case of three-phase generators, in particular generators of a larger type for supplying power to vehicles, the stator of the machine is provided with a multi-pole three-phase shaft or loop winding which is formed from individual conductor bars in the grooves in the stator core. The conductor bars according to DE 37 04 780 AI "are initially bent in a hairpin shape and the legs are interlaced in the upper part, so that they can be inserted in one of the end faces of the laminated core into its grooves in a spreading step by means of a pole division of the laminated stator core. On the other end, the ends of the conductor bars are then interleaved again by a pole pitch, so that the bar ends are welded or soldered together in pairs to form a loop or wave winding, since in such windings between the individual winding trains of each phase, so-called Intermediate and reversing connections are required, one has these additional switching connections in three-phase alternators previously arranged on one side of the stator on the rod ends in the form of additional switching brackets, which were manually welded to the respective conductor rod ends in special, additional operations.
Aus der DE 34 41 825 AI ist bekannt, diese Zusatzschaltverbindungen nicht mehr als separate Zusatzschaltbrücken mit den Stabenden zu verschweißen, sondern sie an dem freien Ende eines jeweils haar- nadelförmig vorgebogenen Leiterstabes anzubringen. Da die haarnadel- för ig vorgebogenen und um eine Polteilung verschränkten Leiterstäbe von einer Seite des Blechpaketes in die Nuten eingesteckt und danach an der anderen Stirnseite des Blechpaketes um eine weitere Pol¬ teilung verschränkt werden, lassen sich diese Serien- und Umkehr¬ verbindungen nur durch zusätzliche Arbeitsgänge am halbfertigen Ständer der Maschine, d. h. nach dem Einstecken der einseitig ver¬ schränkten Leiterstäbe in die Nuten des Ständerblechpaketes durch Abkröpfungen der Stabenden so realisieren, daß dabei die übrigen Stabenden nicht beschädigt werden. Um das Verschränken und Ein¬ stecken sowie Löten bzw. Schweißen der Leitβrstäbe möglichst voll¬ automatisch durchführen zu können, sind diese zusätzlichen Biege¬ maßnahmen am halbfertigen Stator zu vermeiden,From DE 34 41 825 AI it is known that these additional switching connections are no longer welded to the rod ends as separate additional switching bridges, but instead are to be attached to the free end of a hairpin-shaped pre-bent conductor rod. Since the hairpin-shaped pre-bent conductor leads, which are interlaced by a pole pitch, are inserted into the grooves from one side of the laminated core and then interlaced by a further pole pitch on the other end face of the laminated core, these series and reverse connections can only be made by additional operations on the semi-finished stand of the machine, d. H. After inserting the conductor bars entangled on one side into the grooves of the stator core, realize by cranking the bar ends so that the remaining bar ends are not damaged. In order to be able to carry out the entangling and insertion as well as soldering or welding of the guide rods as fully automatically as possible, these additional bending measures on the semi-finished stator must be avoided.
Vorteile der ErfindungAdvantages of the invention
Der erfindungsgemäße Ständer mit den kennzeichnenden Merkmalen des Patentanspruchs 1 hat den Vorteil, daß die Serien- und/oder Umkehr- verbindungen für die einzelnen Züge der Schleifen- oder Wellen¬ wicklung nunmehr ebenso wie die haarnadelförmigen übrigen Leiter¬ stäbe zunächst vorgebogen und dann gemeinsam als eine Einheit über eine Polteilung verschränkt werden können, bevor sie in die Nuten des Blechpaketes eingesetzt werden. Auf der gegenüberliegenden Stirnseite des Blechpaketes können nunmehr sämtliche dort vorstehen¬ den Leiterstäbe der oberen und der unteren Lage erneut um je eine halbe Polteilung gegeneinander verschränkt und ihre übereinander- liegenden Enden paarweise verschweißt oder verlötet werden. Da hier¬ bei alle Löt- bzw. Schweißverbindungen auf einer Stirnseite der Maschine in einer ringförmigen Ebene liegen, können sie maschinell paarweise miteinander verbunden werden, ohne zusätzlichen Verbin¬ dungsschienen oder Abkröpfungen von Leiterstäben.The stand according to the invention with the characterizing features of patent claim 1 has the advantage that the series and / or reverse connections for the individual trains of the loop or wave winding are now prebented as well as the hairpin-shaped other conductor bars and then together as a unit can be crossed over a pole pitch before they are inserted into the grooves of the laminated core. On the opposite end face of the laminated core, all the conductor bars of the upper and lower layers protruding there can again be moved by one each half the pole pitch interlaced and their ends lying one above the other are welded or soldered in pairs. Since all the soldered or welded connections lie on an end face of the machine in an annular plane, they can be mechanically connected to one another in pairs, without additional connecting rails or cranking of conductor bars.
Sämtliche Schritte zur Herstellung eines solchen Ständers lassen sich mit den Verfahrensmerkmalen des Patentanspruchs 4 maschinell durchführen. Dabei werden die U-förmigen Leiterstäbe für eine Zwischenverbindung jeweils um eine halbe Nutbreite gekröpft vor¬ gebogen und die Umkehrverbindungsstäbe werden auf eine Polteilung U-förmig vorgebogen.All steps for the manufacture of such a stand can be carried out mechanically with the method features of claim 4. In this case, the U-shaped conductor rods are bent forward by half a groove width for an intermediate connection, and the reversing connecting rods are pre-bent in a U-shape on a pole pitch.
Durch die in den Unteransprüchen aufgeführten Maßnahmen ergeben sich vorteilhafte Weiterbildungen und Verbesserungen der im Patentan¬ spruch 1 und 4 angegebenen Merkmale. So ist besonders vorteilhaft, für ein maschinelles paarweises Verlöten oder Verschweißen der Leiterstabenden auf der einen Stirnseite des Blechpaketes, wenn die Wicklungsenden für die drei Phasen eines Drehstromgenerators auf der den galvanischen Stabverbindungen abgewandten Stirnseite des Blech¬ paketes herausgeführt sind. Für eine maschinelle Verlötung oder Verschweißung der Leiterstabenden ist ferner darauf zu achten, daß die galvanischen Stabverbindungen am Umfang der Ständerstirnseite nicht zu dicht beieinanderliegen. Zweckmäßigerweise sind dazu in jeder Nut zwei Leiterstäbe der Schleifen- oder Wellenwicklung in einer inneren Lage und zwei in einer äußeren Lage nebeneinander anzuordnen.The measures listed in the subclaims result in advantageous developments and improvements of the features specified in patent claims 1 and 4. It is particularly advantageous, for example, for mechanical pairwise soldering or welding of the conductor rod ends on one end face of the laminated core if the winding ends for the three phases of a three-phase generator are led out on the end face of the laminated core facing away from the galvanic rod connections. For mechanical soldering or welding of the conductor rod ends, care must also be taken to ensure that the galvanic rod connections on the circumference of the end face of the stator are not too close together. For this purpose, two conductor bars of the loop or wave winding are expediently arranged in an inner layer and two in an outer layer next to one another in each slot.
Zur Herstellung des Ständers einer elektrischen Maschine nach dem erfindungsgemäßen Verfahren gemäß Anspruch 4 ist es ferner zweck¬ mäßig die über eine Polteilung U-förmig vorgebogenen Umkehrver¬ bindungsstäbe derart in der Montagevorrichtung aufzunehmen, daß die beiden Schenkel jeweils in gleicher Richtung verschränkt in die äußere Lage der ihnen zugeordneten Nuten eingesteckt werden. Die Zwischenverbindungsstäbe werden dagegen in vorteilhafterweise auf eine halbe Nutbreite seitlich gekröpft U-förmig vorgebogen und in der Montagevorrichtung derart aufgenommen, daß die vorderen Abschnitte der beiden Schenkel zunächst entgegengesetzt verschränkt werden, damit der eine Schenkel in die äußere Lage der einen Nut und der andere Schenkel in die innere Lage einer um eine Polteilung versetzten zweite Nut eingesteckt werden kann. Für eine vollautoma¬ tische Verschweißung oder Verlötung der paarweise übereinander- liegenden Leiterstabenden an einer Stirnseite des Stators ist es außerdem zweckmäßig, die Anschlußenden für jede Phase der Stator-Stabwicklung als gerade Leiterstäbe zusammen mit den Köpfen der übrigen vorgegebenen Leiterstäbe derart in der Montagevor¬ richtung aufzunehmen, daß sie nach dem Verschränken und Einstecken in die Nuten des Ständerblechpaketes über die Köpfe der vorgebogenen Leiterstäbe axial frei vorstehen.To manufacture the stand of an electrical machine according to the method of the invention according to claim 4, it is also expedient to accommodate the reversing connecting rods which are bent in a U-shape in a U-shaped manner in the assembly device in such a way that the two legs are each folded in the same direction in the outer layer of the grooves assigned to them are inserted. The intermediate connecting rods, on the other hand, are advantageously bent to a half groove width and bent in a U-shape and received in the mounting device in such a way that the front sections of the two legs are initially folded in opposite directions, so that one leg is in the outer position of one groove and the other leg can be inserted into the inner layer of a second groove offset by a pole pitch. For fully automatic welding or soldering of the conductor rod ends lying one above the other in pairs on one end face of the stator, it is also expedient for the connection ends for each phase of the stator rod winding to be straight conductor rods together with the heads of the other predetermined conductor rods in this way in the assembly device record that they protrude axially freely after entanglement and insertion into the grooves of the stator core over the heads of the pre-bent conductor bars.

Beschreibung des AusführungsbeispielesDescription of the embodiment
In Figur 1 ist der Ständer eines 12-poligen Drehstromgenerators für Kraftfahrzeuge in raumbildlicher Darstellung mit 10 bezeichnet. Der Ständer 10 beteht aus einem genuteten Blechpaket 11, in dessen 36 Nuten 12 eine Stabwicklung 13 untergebracht ist. Haarnadelf rmig vorgebogene WicklungsStäbe 14 der Stabwicklung 13 sind an ihren auf der hinteren Stirnseite des Ständers liegenden Wicklungsköpfen 14b um eine Polteilung in Umfangsrichtung verschränkt und mit ihren Schenkeln in je einer äußeren und einer inneren Lage in die Nuten 12 des Blechpaketes 11 eingesteckt. An der vorderen Stirnseite des Blechpakets 11 sind die herausstehenden Enden der Schenkel der äußeren und inneren Lage der WicklungsStäbe 14 ebenfalls gegeneinan¬ der um eine Polteilung verschränkt, so daß die Stabenden 14a der äußeren und inneren Lage jeweils paarweise übereinanderliegen und zu einer Wellenwicklung 16 miteinander galvanisch verbunden, d. h. verschweißt oder verlötet sind. Anstelle einer Wellenwicklung kann in entsprechenderweise mit allen Stabverbindungen 18 an einer Stirn¬ seite auch eine Schleifenwicklung realisiert werden.In Figure 1, the stator of a 12-pole three-phase generator for motor vehicles is designated 10 in a spatial representation. The stand 10 consists of a grooved laminated core 11, in the 36 slots 12 a rod winding 13 is housed. Hairpin-shaped pre-bent winding bars 14 of the bar winding 13 are interleaved on their winding heads 14b lying on the rear end of the stator by a pole pitch in the circumferential direction and inserted into the grooves 12 of the laminated core 11 with their legs in an outer and an inner position. On the front end face of the laminated core 11, the protruding ends of the legs of the outer and inner layers of the winding rods 14 are also interlaced by a pole pitch, so that the rod ends 14a of the outer and inner layers lie one above the other in pairs and are galvanically interconnected to form a wave winding 16 connected, ie welded or soldered. Instead of a wave winding, a loop winding can also be implemented in a corresponding manner with all rod connections 18 on one end face.
Figur 2 zeigt das Wickelschema für eine Phase der Wellenwicklung im Ständer 11 des Drehstromgenerators mit einem Wicklungsschritt, von vier Nuten 12 der als Stabwicklung ausgeführten Wellenwicklung 16 . Dabei sind in jeder Nut 12 des Statorblechpaketes 11 zwei Leiter 17 in einer äußeren Lage und zwei weitere Leiter in einer inneren Lage nebeneinanderliegend angeordnet. Die Anschlußenden der drei Phasen der Wellenwicklung 16, von denen in Figur 2 die Enden U und X einer Phase dargestellt sind, liegen wie in Figur 1 auf der hinteren, den galvanischen Stabverbindungen 18 abgewandten Stirnseite des Blech¬ paketes 11. Aus den haarnadelförmig gebogenen, verschränkten und paarweise verschalteten Wicklungsstäben 14 ergibt sich gemäß Figur 2 eine Wellenwicklung 16, indem vom Wicklungsanfang U ein erster Wick¬ lungszug Ul zunächst in die untere Lage der ersten Nut führt, sich dann auf der anderen Stirnseite über eine der Stabverbindungen 18 der mit einer Polteilung T von drei Nuten verschränkten Wicklung in der oberen Lage der vierten Nut 12 fortsetzt, von dort dann wellen¬ förmig abwechselnd in einer unteren und einer oberen Lage mit jeweils einer Polteilung in Umfangsrichtung weitergeführt wird, bis er schließlich in der oberen Lage der dreiunddreißigsten Nut endet. Dieser Wicklungszug Ul wird nun über eine Zwischenverbindung 19 auf den zweiten Leiter in der unteren Lage der ersten Nut 12 fort¬ geschaltet, so daß sich nun ein zweiter Wicklungszug U2 neben dem ersten Wicklungszug Ul anschließt. Das Ende dieses Wicklungszuges U2 liegt nun in der oberen Lage der dreiunddreißigsten Nut 12 und wird über eine Umkehrverbindung 20 auf einen dritten Wicklungszug U3 geschaltet, der um eine Polteilung in entgegengesetzter Umlauf- richtung in der oberen Lage der dreißigsten Nut 12 beginnt, in der unteren Lage der dreiunddreißigsten Nut endet und über eine weitere Zwischenverbindung 19 auf einen vierten Wicklungszug U4 geschaltet wird, der mit dem zweiten Leiter der oberen Lage in der dreißigsten Nut 12 beginnt, in der unteren Lage der dreiunddreißigsten Nut endet und schließlich dort am Anschluß X wieder herausgeführt wird. Eine derartige Wellenwicklung mit vier Wicklungszügen ergibt sich in gleicher Weise für die zwei anderen Phasen des Drehstromgenerators in den von der ersten Phase nicht belegten übrigen Nuten 12. Mit dem gleichen Wicklungsschema können ggf. auch die Umkehrverbindungen 20 mit Anfang und Ende der drei Wicklungsphasen vertauscht werden und/oder es können die Verschränkungen an den Stirnseiten des Blech¬ paketes umgekehrt werden.FIG. 2 shows the winding diagram for a phase of the shaft winding in the stator 11 of the three-phase generator with one winding step, of four slots 12 of the shaft winding 16 designed as a bar winding. In this case, two conductors 17 in an outer layer and two further conductors in an inner layer are arranged side by side in each groove 12 of the stator laminated core 11. The connection ends of the three phases of the wave winding 16, of which the ends U and X of one phase are shown in FIG. 2, lie, as in FIG. 1, on the rear end of the sheet metal package 11 facing away from the galvanic rod connections 18. 2, a wave winding 16 results, according to FIG. 2, in that a first winding pull U 1 leads from the beginning of the winding U first into the lower position of the first slot, then on the other end face via one of the rod connections 18 with a pole pitch T continues winding intertwined by three slots in the upper position of the fourth slot 12, from there then alternating in a wave-like manner in a lower and an upper position one pole pitch is continued in the circumferential direction until it ends in the upper position of the thirty-third slot. This winding train U1 is now connected via an intermediate connection 19 to the second conductor in the lower position of the first slot 12, so that a second winding train U2 is now connected next to the first winding train U1. The end of this winding train U2 now lies in the upper position of the thirty-third slot 12 and is switched via a reversing connection 20 to a third winding train U3, which begins by one pole division in the opposite direction of rotation in the upper layer of the thirtieth slot 12, in the lower one The position of the thirty-third slot ends and is connected via a further intermediate connection 19 to a fourth winding U4, which begins with the second conductor of the upper layer in the thirtieth slot 12, ends in the lower layer of the thirty-third slot and finally leads out again at terminal X there becomes. Such a wave winding with four winding trains results in the same way for the two other phases of the three-phase generator in the remaining slots 12 not occupied by the first phase. With the same winding scheme, the reversing connections 20 with the beginning and end of the three winding phases can also be interchanged and / or the entanglements on the end faces of the laminated core can be reversed.
Um eine möglichst maschinelle Montage der gesamten Stabwicklung 13 im Blechpaket 11 des Ständers 10 realisieren zu können, müssen insbesondere für die Zwischen- und Umkehrverbindungen besondere zusätzliche Kontaktierungs- und und Biegungsvorgänge vermieden werden, die ein einheitliches Verschränken der Wicklungsstäbe an den Stirnenden des Blechpaketes sowie das paarweise Verschweißen der Leiterstabenden auf der einen Stirnseite des Blechpaketes 11 behindern. Zu diesem Zweck werden die WicklungsStäbe 14 ebenso wie die UmkehrverbindungsStäbe 20, ZwischenverbindungsStäbe 19 und Leiterstäbe 21 für die Anschlußenden X, Y getrennt voneinander vorgefertigt. In Figur 3 sind diese vorgefertigten Teile erkennbar. Die Wicklungs- Stäbe 14 sind haarnadelförmig bzw. U-förmig gebogen, so daß einer der beiden Schenkel 14c für die obere und einer für die untere Lage in den Nuten 12 des Blechpaketes 11 zu verwenden ist. Die Anschlu߬ enden einer jeden Phase der Stabwicklung 13 sind als gerade Leiter¬ stäbe 21 nicht vorgebogen. Die Zwischenverbindungsstäbe 19 werden dagegen ähnlich wie die Wicklungsstäbe 14 U-förmig vorgebogen, darüber hinaus aber auch noch um eine halbe Nutbreite seitlich gekröpft, damit ihre Schenkel 19c jeweils neben einem weiteren Leiter der oberen bzw. der unteren Lage einer Nut 12 Platz findet. Die Umkehrverbindungsstäbe 20 sind über eine Polteilung T U-förmig vorgebogen.In order to be able to implement the entire coil winding 13 in the laminated core 11 of the stator 10 as mechanically as possible, in particular for the intermediate and reverse connections, special additional contacting and bending processes must be avoided, which entail a uniform entanglement of the winding rods on the ends of the laminated core and that obstacle in pairs welding the conductor rod ends on one end face of the laminated core 11. For this purpose, the winding rods 14 as well as the reverse connecting rods 20, intermediate connecting rods 19 and conductor rods 21 for the connecting ends X, Y are prefabricated separately from one another. These prefabricated parts can be seen in FIG. The winding rods 14 are hairpin-shaped or U-shaped, so that one of the two legs 14c is to be used for the upper and one for the lower layer in the grooves 12 of the laminated core 11. The connection ends of each phase of the rod winding 13 are not pre-bent as straight conductor rods 21. The intermediate connecting rods 19, on the other hand, are pre-bent in a U-shaped manner similar to the winding rods 14, but are also cranked laterally by half a slot width, so that their legs 19c each have space next to a further conductor of the upper or lower layer of a slot 12. The reversing connecting rods 20 are pre-bent in a U-shaped manner via a pole pitch T.
Mit Hilfe der Figuren 4 bis 7 wird anhand einer teilweisen Umfangsabwicklung dargestellt, auf welche Weise der in Figur 1 gezeigte Ständer 11 einer elektrischen Maschine mit einer in die Nuten 12 des Blechpaketes 11 eingesetzten Stabwicklung 13 maschinell mit Hilfe einer Montiervorrichtung 24 hergestellt werden kann.With the aid of FIGS. 4 to 7, a partial circumferential development is used to show how the stator 11 shown in FIG. 1 of an electrical machine with a rod winding 13 inserted into the grooves 12 of the laminated core 11 can be produced mechanically with the aid of a mounting device 24.
Gemäß Figur 4 werden zunächst die unterschiedlich vorgebogenen WicklungsStäbe 14, Zwischenverbindungsstäbe 19, Umkehrverbindungs- stäbe 20 und Anschlußleiterstäbe 21 in richtiger Reihenfolge gemäß Figur 2 an ihren Köpfen 14b, 19b, 20b bzw. am Ende 21b in einem Haltering 25 aufgenommen. Die Schenkel 14c der Wicklungsstäbe 14 liegen dabei untereinander. Die Schenkel 20c des für jede Phase der Stabwicklung erforderlichen UmkehrverbindungsStabes 20 liegen jeweils oben für die äußere Nutlage. Die beiden Schenkel 20c der für jede Phase benötigten zwei Zwischenverbindungsstäbe 19 liegen seitlich versetzt nebeneinander, wobei sich einer in der oberen Lage und der andere unterhalb eines Schenkels 20c des Umkehrverbindungs- stabs 20 in der unteren Lage befindet. Unter dem oberen Schenkel 19c eines jeden Zwischenverbindungsstabes 19 wird außerdem jeweils ein Anschlußleiterstab 21 im Haltering 25 aufgenommen, dessen Anschlu߬ ende 21b nach außen vorsteht. Um die erforderliche Wickelköpfhöhe der Stabwicklung 13 zurückversetzt sind außerdem zwei konzentrisch ineinanderliegende Verschränkungsringe 26, 27 angeordnet, die - ebenfalls in der Abwicklung ausschnittsweise dargestellt - die Schenkel 14c, 19c, 20c und 21c der Wicklungsstäbe 14, der Zwischen- verbindungsstäbe 19, der Umkehrverbindungsstäbe 20 und der Anschlu߬ leiterstäbe 21 aufnehmen. Der äußere Verschränkungsring 26 nimmt dabei die außenliegenden Schenkel und der innere Verschränkungsring 27 die innenliegenden Schenkel dieser Stäbe auf.According to FIG. 4, the differently pre-bent winding rods 14, intermediate connecting rods 19, reverse connecting rods 20 and connecting conductor rods 21 are received in the correct order according to FIG. 2 on their heads 14b, 19b, 20b or at the end 21b in a retaining ring 25. The legs 14c of the winding bars 14 lie one below the other. The legs 20c of the reversing connecting rod 20 required for each phase of the bar winding are in each case at the top for the outer slot position. The two legs 20c of the two intermediate connecting rods 19 required for each phase lie laterally offset next to one another, one being in the upper position and the other below one leg 20c of the reversing connecting rod 20 in the lower position. Under the upper leg 19c of each interconnection rod 19 there is also one Connection conductor rod 21 is received in the retaining ring 25, the connection end 21b of which protrudes outwards. Also set back around the required winding head height of the bar winding 13 are two concentrically interlocking interlocking rings 26, 27, which - also shown in detail in the development - the legs 14c, 19c, 20c and 21c of the winding bars 14, the intermediate connecting bars 19, the reverse connecting bars 20 and take up the connecting conductor bars 21. The outer interlocking ring 26 takes on the outer legs and the inner interlocking ring 27 on the inner legs of these rods.
Wie Figur 5 zeigt, werden nun die beiden Verschränkungsringe 26, 27 gegeneinander jeweils in Pfeilrichtung um eine halbe Polteilung T/2 verdreht, wodurch die Vorderabschnitte der Schenkel 14c, 19c, 20c und 21c entsprechend jeweils um eine halbe Polteilung des Ständers 10 verschränkt werden. Dadurch ergibt sich für die WicklungsStäbe 14 und die Zwischenverbindungen 19 ein Spreizschritt von einer Pol¬ teilung T, für die Umkehrverbindungsstäbe 20 ergibt sich an den Vorderabschnitten der beiden Schenkel 20c eine Verschränkung in gleicher Richtung um eine halbe Polteilung und ebenso ergibt sich für den entsprechenden Abschnitt der Anschlußleiterstäbe 21 eine Verschränkung um eine halbe Polteilung.As FIG. 5 shows, the two interlocking rings 26, 27 are now rotated relative to one another in the direction of the arrow by half a pole pitch T / 2, as a result of which the front sections of the legs 14c, 19c, 20c and 21c are respectively intertwined by half a pole pitch of the stator 10. This results in a spreading step of one pole pitch T for the winding bars 14 and the intermediate connections 19, for the reversing connecting bars 20 there is an entanglement in the same direction by half a pole pitch on the front sections of the two legs 20c and likewise for the corresponding section the connecting conductor rods 21 are entangled by half a pole pitch.
Die Verschränkungsringe 26, 27 werden nun entfernt und in dem nach¬ folgenden Montageschritt werden die im Haltering 25 aufgenommenen Stäbe in die Nuten 12 des Blechpaketes 11 gemäß Figur 6 eingesteckt, wobei in sämtlichen Nuten 12 jeweils zwei Leiter in der oberen und zwei in der unteren Lage nebeneinander angeordnet sind. In einem weiteren Schritt werden nun die Enden 14a, 19a, 20a und 21a der Wicklungsstäbe 14, Zwischenverbindungen 19, Umkehrverbindungen 20 und Anschlußleiterstäbe 21 in den zwei Verschränkungsringen 26 und 27 aufgenommen und gemäß Figur 7 erneut um jeweils eine halbe Pol¬ teilung T/2 in entgegengesetzte Richtungen gegeneinander verdreht. Wie Figur 7 zeigt, werden dadurch die hinteren Abschnitte aller Stäbe der Stabwicklung 13 in der unteren Lage gegenüber den Stäben in der oberen Lagen gegeneinander verschränkt, so daß die nunmehr paarweise übereinanderliegenden, entgegengesetzt verschränkten Stabenden 14a, 19a, 20a und 21a einen weiteren Spreizschritt von einer Polteilung T bilden. Die Verschränkungsringe 26, 27 werden danach entfernt und in der nachfolgenden Bearbeitungsstelle werden nun die paarweise übereinanderliegenden Stabenden schrittweise miteinander verschweißt oder durch Tauchlötung in einem Arbeitsgang paarweise verlötet. Dabei ist es zweckmäßig, die Isolierung an den Stabenden bereits vor der Aufnahme der Wicklungsstäbe 14 in den Haltering 25 zu entfernen, sofern diese sich nicht durch Erhitzung, Elektrodendruck und dergleichen bei der paarweisen Kontaktierung der Stabenden in ausreichend Maß beseitigen läßt. The interlocking rings 26, 27 are now removed and in the subsequent assembly step, the rods received in the retaining ring 25 are inserted into the grooves 12 of the laminated core 11 according to FIG. 6, with two conductors in the upper and two in the lower in all grooves 12 Layer are arranged side by side. In a further step, the ends 14a, 19a, 20a and 21a of the winding rods 14, intermediate connections 19, reversing connections 20 and connecting conductor rods 21 are received in the two interlocking rings 26 and 27 and again according to FIG. 7 by half a pole pitch T / 2 twisted in opposite directions. As FIG. 7 shows, the rear sections of all the bars of the bar winding 13 in the lower position are entangled with one another in relation to the bars in the upper positions, so that the bar ends 14a, 19a, 20a and 21a, which are now overlapping in pairs and oppositely entangled, undergo a further spreading step of form a pole pitch T. The entanglement rings 26, 27 are then removed and in the subsequent processing point the rod ends lying one above the other in pairs are welded to one another step by step or soldered in pairs in one operation by dip soldering. It is expedient to remove the insulation at the rod ends before the winding rods 14 are received in the retaining ring 25, provided that this cannot be eliminated to a sufficient extent by heating, electrode pressure and the like when the rod ends are contacted in pairs.
