Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bisher wurden die Ständer elektrischer Maschinen, besonders von Wechselstrommotoren, in der Weise aufgebaut, dafs die Bleche durch ein gufseisernes Gehäuse oder durch Bolzen, welche die Bleche durchquerten, in ihrer Lage zusammengehalten wurden. Die vorliegende Erfindung bezweckt, die gufseisernen Gehäuse und die durchgehenden Bolzen, welche einen beträchtlichen Materialaufwand an Blechscheiben bedingen, zu vermeiden. Bei derartig gebauten Maschinen wird daher nur ein Minimum an Blech verbraucht, wodurch gleichzeitig die elektrischen und magnetischen Eisenverluste stark vermindert werden, während durch den Fortfall der gufseisernen Gehäuse zugleich die Wärmeausstrahlung begünstigt wird. Letzteres hat noch den Vortheil, dafs die elektrische und magnetische Beanspruchung höher sein kann, als bei der Dynamomaschine üblicher Bauart.So far, the stands of electrical machines, especially AC motors, constructed in such a way that the sheets are secured by a cast iron housing or by bolts, which traversed the sheets were held together in their position. The present Invention aims, the cast iron housing and the through bolts, which one require considerable material expenditure on sheet metal disks, to be avoided. With such a built Machines therefore only use a minimum of sheet metal, which at the same time reduces the electrical and magnetic iron losses are greatly reduced while by the Elimination of the cast iron housing at the same time the heat radiation is favored. The latter has the advantage that the electrical and magnetic stress can be higher, than the usual type of dynamo machine.

Die Bleche b der Ständer werden durch Prefsringe α und eine beliebige Anzahl Bolzen c zusammengehalten, die in Nuthen am Umfange der Bleche nur so weit eingreifen, dafs eine Verdrehung der Bleche unmöglich ist.The plates b of the uprights are held together by pressing rings α and any number of bolts c , which only engage in grooves on the circumference of the plates to such an extent that a rotation of the plates is impossible.

Die Bolzen und entsprechend auch die Nuthen können runde oder eckige Formen haben und dienen gleichzeitig zur Befestigung der Lagerträger. An den Prefsringen sind die Füfse des Motors angegossen.The bolts and, accordingly, also the grooves can have round or angular shapes and serve at the same time to fasten the bearing brackets. The feet are on the pre-rings cast on the engine.

In Fig. ι ist in der oberen Hälfte ein Längsschnitt, in der unteren eine Ansicht, in Fig. 2 ein Querschnitt, in Fig. 3 eine Seitenansicht der Construction dargestellt.In Fig. Ι is a longitudinal section in the upper half, in the lower a view, in Fig. 2 a cross section, in Fig. 3 a side view of the Construction shown.

Patent-Ansprüche:Patent Claims: 1. Aufbau von Ständerkernen für elektrische Maschinen aus Eisenblech, dadurch gekennzeichnet, dafs die zusammenhaltenden und die gegenseitige Verschiebung der Bleche verhindernden Bolzen, anstatt diese zu durchsetzen, nur in Ausschnitte am Umfange der Bleche eingreifen und diese durch Druckringe und Muttern zusammenhalten.1. Structure of stator cores for electrical machines made of sheet iron, characterized in that that the holding together and the mutual displacement of the plates preventing bolts, instead of blocking them enforce, only reach into cutouts on the circumference of the metal sheets and push them through Hold pressure rings and nuts together. 2. Eine Ausführung des Aufbaues nach Anspruch ι, bei welchem die~ Druckringe gleichzeitig die Füfse und die Wellenlager tragen, so dafs ein geschlossenes Gehäuse entbehrlich wird.2. An embodiment of the structure according to claim ι, in which the ~ pressure rings at the same time the feet and the shaft bearings carry, so that a closed housing becomes dispensable. Hierzu 1 Blatt Zeichnungen.1 sheet of drawings.
