Description
Elektrische Maschine mit abgestützten Wickelköpfen. Bei elektrischen Maschinen für hohe Leistungen, deren Leiterstäbe größere Länge aufweisen; muß zur Vermeidung von Beschädigungen auf die Wärmeausdehnung der Leiterstäbe Rücksicht genommen werden. Die Wärmeausdehnung der Leiterstäbe wird aber bei den bekannten Ausführungen durch die Abstützung der Wickelköpfe verhindert. Erfindungsgemäß soll dieser Übelstand bei Maschinen mit abgestützten Wickelköpfen dadurch beseitigt werden, daß die Abstützung selbst, wie die Abbildung zeigt, achsial verschiebbar ausgebildet ist.Electric machine with supported winding heads. With electrical Machines for high performance, the ladder bars of which are of greater length; must go to Avoid damage to the thermal expansion of the conductor bars be taken. The thermal expansion of the conductor bars is, however, with the known Executions prevented by the support of the winding heads. According to the invention this disadvantage in machines with supported winding heads can be eliminated, that the support itself, as the figure shows, designed to be axially displaceable is.
Die aus dem Eisenblechkörper a heraustretenden Leiterenden bl-, b2 sind danach in gewohnter Weise durch Bügel o paarweise verbunden. Die Wickelköpfe werden dabei in achsialer Richtung mittels Schraubbolzen d zusammengepreßt, die als Rohre ausgebildet sind. Diese rohrförmigen Preßbolzen d sind selbst auf Abstützbolzen e lose aufgesetzt, so daß sie sich auf diesen achsial verschieben können, während sie durch die Abstützbolzen an einer radialen oder tangentialen Bewegung gehindert werden. Die Abstützbolzen e- sind hierzu zweckmäßig noch mit Versteifungsringen f versehen.The conductor ends bl-, b2 emerging from the sheet-iron body a are then connected in pairs in the usual way by brackets o. The winding heads are pressed together in the axial direction by means of bolts d, the are designed as tubes. These tubular press bolts are d self loosely placed on support bolts e so that they move axially on them can while they are through the support bolts on a radial or tangential Movement are prevented. The support bolts e- are also useful for this purpose Stiffening rings f provided.
Damit durch Aufschrauben der Muttern g auf die Preßbolzen d ein Zusammenpressen der Wickelköpfe vorgenommen werden kann, sind die rohrförmigen Preßbolzen gegen Drehung gesichert. Das wird dadurch erreicht, daß die Bolzenköpfe h unrund geformt und mit entsprechend geformten Teilen i in Eingriff gebracht sind, die ihrerseits auf der Endplatte k -des Blechkörpers a oder den daran befestigten Bolzen e derart angebracht sind, daß sie nicht gedreht werden können.So that the winding heads can be pressed together by screwing the nuts g onto the pressing bolts d, the tubular pressing bolts are secured against rotation. This is achieved in that the bolt heads h are shaped out of round and are brought into engagement with correspondingly shaped parts i, which in turn are attached to the end plate k of the sheet metal body a or the bolt e attached to it in such a way that they cannot be rotated.
Im Gegensatz zu einer bekannten Ausführung, bei der die Abstützung nur entgegen der VGTirkung der Feder achsial verschiebbar ist, können danach bei der neuen Anordnung, wie ohne weiteres ersichtlich ist, die Wickelköpfe der Wärmeausdehnung der Leiter b', b2 ungehindert folgen, indem sich die Preßbolzen d auf den Abstützbolzen e einfach entsprechend verschieben. Die Pressung der Wickelköpfe, ebenso wie ihre Abstützung, wird dabei in keiner Weise beeinträchtigt.In contrast to a known design, in which the support can only be axially displaced against the VGTirkung of the spring, the winding heads can then follow the thermal expansion of the conductors b ', b2 unhindered in the new arrangement, as can be seen Simply move the press bolt d onto the support bolt e accordingly. The compression of the winding heads, as well as their support, is not impaired in any way.
Selbstverständlich sind in den Einzelheiten der Ausführung mancherlei Änderungen möglich. So kann die Versteifung der Abstützbolzen beispielsweise, statt durch besondere Ringe f, gegebenenfalls auch einfach mittels der Schutzkappe erfolgen. Dabei kann man dann auch die besonderen Preßbolzen d Wegfällen lassen, indem die Abstützbolzen selbst verschiebbar ausgebildet werden. Sie können zu,diesem Zweck etwa an beiden Enden glatte Zapfen erhalten, von denen der eine in der Endplatte, der andere in der Schutzkappe geführt wird.There are, of course, many things in the details of the execution Changes possible. For example, the stiffening of the support bolts can take place by means of special rings f, optionally also simply by means of the protective cap. You can then also omit the special press bolts d by the Support bolts themselves are designed to be displaceable. You can, to that end at both ends smooth pegs are obtained, one of which is in the end plate, the other is guided in the protective cap.
