Description

Bei den Läufern elektrischer Maschinen werden die frei vorstehenden Köpfe der Ankerwicklung in der Regel durch eine am Umfang des Wickelkopfes aufgebrachte Bandage gegen die Wirkung der Schleuderkräfte geschützt. Wenn die Wickelköpfe sehr kurz sind, wie das z. B. bei vielpoligen Wicklungen der Fall ist, bereitet die Befestigung der Bandagen gegen das Abrutschen gewisse Schwierigkeiten, da die Bandage aus elektrischen Gründen von den metallischen Teilen des Ankers isoliert sein muß. -Nach der Erfindung läßt sich eine einwandfreie Befestigung der Bandage dadurch erreichen, daß die zur Befestigung dienenden Blechstreifen vor dem Einlegen der Wicklung mittels einer besonderen Bandage isoliert auf einem Wickelkopfträger befestigt und durch an :ich bekannte, in den Hohlräumen des Wickelkopfes angeordnete Isolationskörper gegen aziale #-erlagerung gesichert sind.In the case of the rotors of electrical machines, the freely protruding Heads of the armature winding usually by one applied to the circumference of the winding head Bandage protected against the effects of centrifugal forces. When the winding heads are very are short, as z. B. is the case with multi-pole windings, prepares the attachment The bandages against slipping off certain difficulties because the bandage is made of electrical Reasons must be isolated from the metallic parts of the anchor. -After the invention perfect attachment of the bandage can be achieved in that the for Fixing serving sheet metal strips before inserting the winding by means of a special bandage isolated on a winding head support and attached through to: me known, arranged in the cavities of the winding head insulation body against social # storage are secured.

In Fig. I der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Der Ankerkörper ist mit a bezeichnet. Er besteht aus einzelnen Blechen, auf die an den Enden des Ankers Isolationsscheiben _1r gelegt sind, wobei das ganze Blechpaket durch Endscheiben c zusammengehalten wird, die auf der Welle aufgeschrumpft oder sonst in bekannter Weise befestigt sind. Mit den Endscheiben c fest verbunden ist ein Ring d, der als Träger des Wickelkopfes t° dient. Der Wickelkopf wird von den Stirnverbindungen f der in _Nuten g angeordneten Ankerwicklung gebildet. Diese Stirnverbindungen müssen gegen die Wirkung von Schleuderkräften geschützt «-erden, wozu bekanntlich eine aus mehreren Windungen von Stahldraht bestehende Bandage lt dient. Um diese Bandage gegen das Abrutschen zu sichern, werden besOndere Bandagenhalter i benutzt, die aus schmalen Blechstreifen bestehen und in der erfindungsgemäßen Weise befestigt werden. Die Blechstreifen werden vor dem Einlegen der Ankerwicklung auf dem Wickelkopfträger d unter Zwischenlegung von Isolationsstreifen k mittels einer Stahldrahtbandage 1 befestigt und mit dieser Bandage verlötet. Während des Einträufelns der Wicklung durch die -Hutschlitze in sind die freien Enden der Blechstreifen über den Anker zurückgebogen, wie bei t angedeutet. -Nach Fertigstellung der Wicklung werden die freien Enden der Blechstreifen unter Zwischenlegung von Isolationsstreifen a über die Wicklung nach vorn gebogen und mit der Bandage h bewickelt. Danach werden die noch vorstehenden freien Enden wieder nach rückwärts über die fertige Bandage gebogen und mit dieser verlötet. Die Bandagenhalter sind vor einer größeren Anzahl von Ankerzähnen in angemessenen Abständen angeordnet. Damit sie in den von den Stirnverbindungen der Wicklung gebildeten Hohlräumen festsitzen, werden diese vor dem Aufbringen der Bandage gemäß Fig. 3 in an sich bekannter Weise mit Holz- bzw. Isolierkörpern p ausgefüllt, «-elche die Blechstreifen fest gegen die Stirnseite des Ankers drücken.In Fig. I of the drawing, an embodiment of the invention is shown. The anchor body is denoted by a. It consists of individual metal sheets on which insulation disks _1r are placed at the ends of the armature, the entire laminated core being held together by end disks c which are shrunk onto the shaft or otherwise fastened in a known manner. Firmly connected to the end disks c is a ring d which serves as a carrier for the end winding t °. The end winding is formed by the end connections f of the armature winding arranged in grooves g. These end connections must be protected against the effects of centrifugal forces, for which purpose, as is well known, a bandage consisting of several turns of steel wire is used. In order to secure this bandage against slipping off, special bandage holders i are used, which consist of narrow sheet metal strips and are fastened in the manner according to the invention. Before the armature winding is inserted, the sheet metal strips are fastened to the end winding support d with the interposition of insulation strips k by means of a steel wire bandage 1 and soldered to this bandage. During the instillation of the winding through the hat slots in , the free ends of the sheet metal strips are bent back over the armature, as indicated at t. -After completion of the winding, the free ends of the sheet metal strips are bent over the winding with the interposition of insulation strips a and wrapped with the bandage h. The free ends that are still protruding are then bent backwards over the finished bandage and soldered to it. The bandage holders are spaced appropriately in front of a larger number of anchor teeth. So that they sit firmly in the cavities formed by the end connections of the winding, these are filled in a known manner with wooden or insulating bodies p before the bandage is applied according to FIG .

Fig. 2 zeigt den Anker in Stirnansicht. Die Erfindung hat gegenüber anderen bekannten Ausführungen den Vorteil, daß in den Bandagen und ihren Haltern keine Wirbelströme durch die Einwirkung des magnetischen Feldes entstehen können.Fig. 2 shows the anchor in front view. The invention has opposite other known designs have the advantage that in the bandages and their holders no eddy currents can arise from the action of the magnetic field.
