Description
Die Erfindung betrifft ein Stehlager, insbesondere ein Gleitlager, für elektrische Maschinen.The invention relates to a pillow block bearing, in particular a plain bearing, for electrical machines.
Die Fig. I zeigt die bisherige Ausbildung eines solchen Lagers und die übliche Bauform einer geschlossenen elektrischen Maschine, der die Frischluft aus der Fundamentgrube durch die Lufthosen I an den beiden Stirnseiten zugeführt wird. Außerhalb der Lufthosen I sind die Stehlager 2 angeordnet, die auf der Grundplatte 3 aufgestellt sind.Fig. I shows the previous design of such a camp and the usual design of a closed electrical machine that draws fresh air fed from the foundation pit through the air pants I on the two end faces will. Outside the air pants I, the pillow block bearings 2 are arranged on the base plate 3 are set up.
Die Weiterentwicklung führte dahin, daß das Gestell der Lager mit einem vergrößerten durchbrochenen Fuß versehen wurde, der ein Luftzuführungsgehäuse für die Maschine bildete. Der Kraftfluß der auftretenden Lagerkräfte wird also durch den Grundrahmen geschlossen. Die durch den durchbrochenen Fuß strömende Kühlluft wurde dabei unter der Wandung des Ölraumes entlanggeführt, um eine Kühlung des Schmieröles zu erreichen. Die Lager derartig bekanntgewordener Maschinen liegen jedoch frei auf dem Fuß.The further development led to the fact that the frame of the camp with an enlarged openwork foot was provided, which an air supply housing made for the machine. The power flow of the bearing forces that occur is thus through the base frame closed. The cooling air flowing through the perforated foot was guided along under the wall of the oil chamber in order to cool the lubricating oil to reach. However, the bearings of machines that have become known in this way are exposed on the foot.
Um nun eine weit bessere Kühlung des Schmieröles und des Lagers zu erhalten und um eine geschlossene Bauweise zu erzielen, kommt nach der Erfindung ein Stehlager zur Anwendung, das zweiteilig ausgeführt ist, einen vergrößerten, nach unten durchbrochenen Fuß aufweist und so ausgebildet ist, daß der Kühlluftstrom durch den Fuß des Gestelles eintritt und die Wandungen des Ölraumes unmittelbar allseitig und über die ganze Länge des Lagers umspült. Vorteilhaft dabei ist eine Verkürzung der gesamten Maschine, weil der hohle Fuß gleichzeitig der Kühlluftverteilung auf den gesamten Umfang der Maschine dient. Es ist also nicht notwendig, innerhalb des Gehäuses der Maschine beidseitig einen besonderen Raum für die Verteilung der Kühlluft vorzusehen, so daß auch die Welle der Maschine kürzer wird bzw. die Lager näher aneinanderrücken.In order to achieve a much better cooling of the lubricating oil and the bearing obtained and to achieve a closed construction, comes according to the invention a pillow block bearing for use, which is designed in two parts, an enlarged, has downwardly perforated foot and is designed so that the cooling air flow enters through the foot of the frame and the walls of the oil chamber directly Washed around on all sides and over the entire length of the camp. One advantage here is Shortening of the entire machine because the hollow foot also distributes the cooling air serves on the entire scope of the machine. So it is not necessary within of the machine housing on both sides a special space for the distribution of the Provide cooling air so that the shaft of the machine is shorter or the bearings move closer together.
Die Erfindung ist in den Fig. 2, 3 a und 3 b in einem Ausführungsbeispiel veranschaulicht. Gemäß der Erfindung ist, wie die Fig. 2 zeigt, der Stehlagerbock mit der Lufthose zu einer konstruktiven Einheit 4 zusammengefaßt. Die Frischluft tritt bei dem in der Fig. 2 dargestellten Ausführungsbeispiel der Erfindung durch die Grundplatte 5 von unten in die Stehlagerböcke ein, die zu diesem Zweck einen vergrößerten durchbrochenen Fuß besitzen und zu einem Luftzuführungsgehäuse ausgebildet sind.The invention is in Figs. 2, 3 a and 3 b in one embodiment illustrated. According to the invention, as FIG. 2 shows, the pillow block combined with the air pants to form a structural unit 4. The fresh air occurs in the embodiment of the invention shown in FIG the base plate 5 from below into the pedestal bearing blocks, which for this purpose a Have enlarged perforated foot and formed into an air supply housing are.
In den Fig. 3 a und 3 b sind die zu Luftzuführungsgehäusen ausgebildeten Stehlager genauer dargestellt. Diese Stehlager weisen das besondere Merkmal auf, daß der im Innern des Stehlagers angeordnete Lagerkopf, der den Ölvorrat des Lagers enthält, unmittelbar von der durchströmenden Frischluft umspült wird. Bei dem in den Fig. 3a und 3b dargestellten Ausführungsbeispiel ist im übrigen eine Lagerschale 6 beispielsweise kugelig in Querträgern 7 gelagert, die ihrerseits durch Längsträger 8 und Wandteile 9 mit der Außenwandung des Stehlagers verschweißt sind. Der so gebildete Lagerkopf kann aber ebensogut durch eine Schraubverbindung mit dem Lagergestell verbunden und dabei für sich, geschweißt oder gegossen, hergestellt sein.In FIGS. 3 a and 3 b, the air supply housings are formed Plummer block shown in more detail. These pillow block bearings have the special feature that the bearing head arranged inside the pillow block bearing the oil supply of the bearing contains, is immediately washed around by the fresh air flowing through. The in The embodiment shown in FIGS. 3a and 3b is, moreover, a bearing shell 6, for example, supported spherically in cross members 7, which in turn are supported by longitudinal members 8 and wall parts 9 are welded to the outer wall of the pedestal bearing. The so educated However, the bearing head can just as easily be connected to the bearing frame by a screw connection connected and thereby manufactured for themselves, welded or cast.
