Description

Die Erfindung betrifft eine Kühleinrichtung für das Schmieröl, insbesondere an Brennkraftmaschinen, das durch die hohle Welle zu den Lagerstellen geleitet wird, und besteht zunächst darin, daß der Ölstrom zwischen der Einführungsstelle in die Welle und den Schmierstellen einen auf der Welle angeordneten Ölkühler durchfließt.The invention relates to a cooling device for the lubricating oil, in particular on internal combustion engines, which is passed through the hollow shaft to the bearing points, and consists first of all in that the oil flow between the point of introduction into the Shaft and the lubrication points flows through an oil cooler arranged on the shaft.

Zweckmäßig ist die hohle Welle zwischen der Einführungsstelle des Ölstromes und der Zuführungsstelle zum Kühler mit einer zwischen ihren Enden eingeschnürten Hülse versehen, die einen Ringraum zum Überleiten des Öles in den Kühler bildet, während das Hülseninnere als Ableitung des gekühlten Öles dient.The hollow shaft between the insertion point of the is useful Oil flow and the feed point to the cooler with a constricted between their ends Provided a sleeve that forms an annular space for transferring the oil into the cooler, while the inside of the sleeve serves as a drainage point for the cooled oil.

Der Kühler kann außen mit schaufelartigen Rippen versehen sein, die Kiihlwind für die luftgekühlten Zylinder der Maschine abgeben.The cooler can be provided with blade-like ribs on the outside, which Give off cooling wind for the air-cooled cylinders of the machine.

Es sind bereits scheibenförmige, z. B. als Schwungrad ausgebildete Ölkühler bekannt, bei denen das Öl durch die hohle Welle zu-und abgeführt wird. An diesen beiden Stellen, an denen das Öl ein- bzw. austritt, ist eine gute Abdichtung erforderlich, um Ölverluste zu vermeiden. Es ist aber bekanntlich sehr schwierig, ja, praktisch fast unmöglich, eine dauerhafte Öldichtung zwischen zwei sich bewegenden Teilen zu erzielen. Diese Schwierigkeit wird nach der Erfindung vermieden. denn hier wird die eine Abdichtungsstelle ganz beseitigt, weil das Öl vom Kühler unmittelbar den zu schmierenden Lagerstellen zufließt. Die Stelle. an der das Öl eingeführt wird, liegt zweckmäßig in an sich bekannter Weise innerhalb eines Wellenlagers, so daß etwa austretendes Öl zweckentsprechend verwendet wird.There are already disc-shaped, z. B. trained as a flywheel Oil coolers are known in which the oil is supplied and discharged through the hollow shaft. There is a good seal at these two points where the oil enters and exits required to avoid oil loss. It is well known that it is very difficult yes, practically almost impossible to have a permanent oil seal between two moving ones Share to achieve. This difficulty is avoided according to the invention. because here the one sealing point is completely eliminated, because the oil from the cooler is immediate flows towards the bearing points to be lubricated. The spot. at which the oil was introduced is conveniently located in a known manner within a shaft bearing, so that any oil that escapes is used appropriately.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung an Hand eines in Achsenrichtung durch das hintere Ende der Kurbelwelle und des Schwungrades verlaufenden Schnittes veranschaulicht.In the drawing, an embodiment of the invention is on hand one axially through the rear end of the crankshaft and the flywheel running cut illustrated.

Im hinteren Lager 2 einer Brennkraftmaschine, in dem das Ende der Kurbelwelle i gelagert ist. ist eine Ringnut 13 vorgesehen. die an eine Ölzuleitung 3 angeschlossen ist. Die Kurbelwelle hat eine radiale Bohrung .I. die mit der Ringnut 13 in ständiger Verbindung steht und das zugeführte Öl in den Innenraum des hohlen Kurbelwellenzapfens leitet. In diesen Innenraum ist eine Buchse 5 eingesetzt, die einen Ringkanal 6 abteilt. In diesem mündet die Bohrung 4. sowie weitere radiale Bohrungen i.I, durch die das zugeführte Öl in den scheibenförmigen Hohlraum des auf der Kurbelwelle befestigten Schwungrades 15 fließt. Dieser Hohlraum ist durch eine ebene, ringförmige Wand io, die zweck-In mit der Nabe des Schwungrades aus einem Stück besteht, in zwei Kammern 7 und 16 unterteilt, die am Umfang miteinander in Verbindung stehen. Von der Kammer 16 aus führen radiale Bohrungen i i in den Hohlraum des Kurbelwellenzapfens. Das Öl fließt von hier aus durch Kanäle 1-2 den einzelnen Lagerstellen zu.In the rear bearing 2 of an internal combustion engine, in which the end of the crankshaft i is mounted. an annular groove 13 is provided. which is connected to an oil supply line 3. The crankshaft has a radial bore .I. which is in constant communication with the annular groove 13 and guides the supplied oil into the interior of the hollow crankshaft journal. A bushing 5 , which divides an annular channel 6, is inserted into this interior space. The bore 4. and further radial bores iI through which the supplied oil flows into the disk-shaped cavity of the flywheel 15 fastened to the crankshaft open into this. This cavity is subdivided into two chambers 7 and 16, which are in communication with one another on the circumference, by a flat, annular wall which is made in one piece with the hub of the flywheel. Radial bores ii lead from the chamber 16 into the cavity of the crankshaft journal. The oil flows from here through channels 1-2 to the individual bearings.

Die Stirnwand S des Schwungrades 15 hat im wesentlichen radial verlaufende Rippen 9. die eine kräftige Luftströmung herbeiführen und dadurch die Kühlwirkung verbessern. Wenn das Öl daher zunächst die Kammer 7 und dann die Kammer 16 durchflossen hat, ist seine Temperatur erheblich herabgesetzt.The end wall S of the flywheel 15 has essentially radially extending ribs 9, which induce a powerful air flow and thereby improve the cooling effect. When the oil has therefore first flowed through chamber 7 and then through chamber 16, its temperature is considerably reduced.

Der durch die Rippen 9 erzeugte Kühlwind kann auch zum Kühlen der Zvlinder herangezogen werden.The cooling wind generated by the ribs 9 can also be used to cool the Zvlinder can be used.
