Description
Die Erfindung bezieht sich auf eine Stütze für Ständerwicklungskäpfe elektrischer Maschinen mit N ormalspulenwicklung, insbesondere für größere Drehstrommaschinen, und hat die Aufgabe, die Wicklungsköpfe gegen magnetische Beanspruchungen sicher zu versteifen.The invention relates to a support for stator winding heads electrical machines with normal coil winding, especially for larger three-phase machines, and has the task of protecting the winding heads against magnetic stress to stiffen.
Es ist bekannt, die Wicklungsköpfe elektrischer Maschinen durch Ringscheiben bzw. Briden zu versteifen, die mit axial angeordneten Schraubenbolzen an den Druckplatten des Ständerbleches befestigt sind. Bei größeren Wicklungsausladungen und damit größeren Bolzenlängen sind diese Stützen nicht mehr genügend stabil. Man hat daher eine weitere Abstützung in radialer Richtung gegen das Lagerschild oder den Wicklungsschutz vorgesehen. Infolge der vielen erforderlichen Schraubenbolzen der Ringscheiben sind diese Wicklungsversteifungen sehr schwer undkompliziert. Außerdem verlängern sie die axiale Baulänge der Maschine. Ein weiterer Nachteil besteht darin, daß die Radialabstützungen bei Abnahme der Lagerschilde oder Wicklungsschilde abgeschraubt werden müssen.It is known that the end windings of electrical machines are provided with annular disks or to stiffen clamps with axially arranged screw bolts on the pressure plates of the stator plate are attached. With larger winding projections and thus larger ones These supports are no longer sufficiently stable through bolt lengths. So you have another one Support is provided in the radial direction against the end shield or the winding protection. As a result of the large number of screw bolts required for the ring disks, these are winding stiffeners very difficult and complicated. They also extend the overall axial length of the machine. Another disadvantage is that the radial supports when the Bearing shields or winding shields must be unscrewed.
Durch die Erfindung werden diese Stützen für Ständerwicklungskäpfe elektrischer Maschinen mit Normalspulenwicklung erheblich vereinfacht. Erfindungsgemäß sind die Stützen an den Rippen des Ständergehäuses befestigt.The invention makes these supports for stator winding heads electrical machines with normal coil winding considerably simplified. According to the invention the supports are attached to the ribs of the stator housing.
Die Zeichnung (Fig. i und 2) zeigt ein Ausführungsbeispiel der Erfindung in zwei verschiedenen Ansichten.The drawing (Fig. I and 2) shows an embodiment of the invention in two different views.
i ist das Maschinengehäuse mit den Rippen 2. 3 sind .an den Rippen befestigte Wickelstücke, gegen die die Wicklungsköpfe d. abgestützt sind. Sie werden durch Bandagen an den Winkelstücken befestigt. Unter Umständen können, wie bei 5o angedeutet, auch auf den gegenüberliegenden Rippenseiten winkelförmige Stützteile angebracht werden.i is the machine housing with the ribs 2. 3 are .on the ribs attached winding pieces against which the winding heads d. are supported. you will be attached to the elbows by bandages. Under certain circumstances, as with 5o indicated, also on the opposite rib sides angular support parts be attached.
Besonders vorteilhaft ist es, die Gehäuserippen gemäß Fig. 3 und 4. anzuordnen. Auf den gegenüberliegenden Seiten A, B sind die Rippen 2 unter einem Zentriwinkel von 6o° gegeneinander versetzt. Hierauf folgen zu beiden Seiten des einen Rippenpaares unter einer Versetzung von je 30° zwei weitere Rippen. Diese Anordnung ergibt eine besonders günstige Wicklungsabstützung, da sie sowohl für vierpolige wie für sechspolige Maschinen, d. h. für die gangbarsten Polzahlen, verwendbar sind.It is particularly advantageous to use the housing ribs according to FIGS. to arrange. On the opposite sides A, B the ribs 2 are under one Central angle offset from one another by 60 °. This is followed on both sides of the a pair of ribs with an offset of 30 °, two more ribs. These Arrangement results in a particularly favorable winding support, as it is for both four-pole as for six-pole machines, d. H. can be used for the most common number of poles are.
Die .Erfindung bietet den Vorteil, daß in einfacher Weise, insbesondere unter Ausnutzung der an sich vorhandenen Gehäuserippen, die Wicklungsköpfe zuverlässig abgestützt werden können. Bei Abnahme der Lagerschilde oder Wicklungsschilde bleibt die Abstützung davon völlig unberührt. Durch die direkte Radialabstützung über den Wickelköpfen wird auch eine Verkürzung der Baulänge und durch die Vereinfachung der Abstützung eine wesentliche Material- und Gewichtsersparnis erzielt.The .Erfindung has the advantage that in a simple manner, in particular using the housing ribs that are actually present, the winding heads are reliable can be supported. If the end shields or winding shields are removed, it remains the support is completely unaffected. Due to the direct radial support via the End winding will also reduce the overall length and simplify it the support achieved a significant material and weight saving.
