Description

Vorrichtung zum Schmieren der Lager schnell umlaufender Maschinenteile, vorzugsweise der Planetenradlager in Ausgleichgetrieben Die Erfindung bezieht sich auf eine Vorrichtung zum zwangsweisen Schmieren der Lager schnell umlaufender Maschinenteile, vorzugsweise der Planetenradlager in Ausgleichgetrieben. Es sind bereits Planetenrädergetriebe mit Druckölschmierung bekannt. Dabei wird ein Teil des zugeführten Drucköles einem umlaufenden Ölfangring zugeführt, von dem aus es dann zu dem Lager des Planetenrades gelangt. Diese Ausführung setzt das Vorhandensein einer Öldruckpumpe voraus.Device for lubricating the bearings of fast rotating machine parts, preferably the planetary gear bearings in differential gears The invention relates on a device for the forced lubrication of the bearings of fast rotating machine parts, preferably the planetary gear bearings in differential gears. There are already planetary gears known with pressure oil lubrication. In this case, part of the pressure oil supplied is a circulating oil catch ring supplied from which it then to the bearing of the planetary gear got. This version requires the presence of an oil pressure pump.

Es sind auch bereits Kurbelwellenschmierungen bekanntgeworden, bei denen die schmierbedürftige Lagerstelle in der Randzone eines schnell umlaufenden, verhältnismäßig großen Kraftübertragungsgliedes angeordnet ist und wobei ein mit dem Kraftübertragungsglied umlaufender Ölfangring vorgesehen ist, von dem aus Schmierkanäle zu den einzelnen Schmierstellen führen. Bei dieser bekannten Ausführung einer Schmiervorrichtung fließt das Öl dem ölfangring entweder aus einem benachbarten Wellenlager zu, so daß -man in gewissem Sinne von einem abgeschleuderten Öl sprechen kann, das von dem Ölfangring aufgenommen wird, oder aber es wird dem Fangring durch eine Leitung unter Druck zugeführt.There are also already known crankshaft lubrication at where the bearing point in need of lubrication is in the edge zone of a rapidly rotating, relatively large power transmission member is arranged and wherein a with the power transmission member is provided revolving oil catch ring, from which lubrication channels lead to the individual lubrication points. In this known embodiment of a lubricating device If the oil flows to the oil catch ring either from an adjacent shaft bearing, see above that in a certain sense one can speak of an oil thrown off, that of the oil catch ring is added, or it is the catch ring through a line fed under pressure.

Gegenüber diesen bekannten Ausführungsformen geht die Erfindung von der Aufgabe aus, die bekannte Tauchschmierung, d. h. also eine Schmierung ohne Anwendung einer Druckpumpe, durch z usa ätzliche Anwendung eines an sich bekannten Öl--fangringes, aus dem das Öl durch die Fliehkraft den zu schmierenden Stellen zugeführt wird, zu verbessern. Die Erfindung betrifft neben der Verbesserung der Tauchschmierung auch die dazu erforderlichen Mittel.In relation to these known embodiments, the invention is based on the task of using the well-known splash lubrication, d. H. so a lubrication without application a pressure pump, due to the caustic application of an oil catch ring known per se, from which the oil is fed to the points to be lubricated by centrifugal force, to to enhance. The invention relates to the improvement of Splash lubrication also provides the means required for this.

Die Erfindung betrifft somit eine Vorrichtung zum zwangsweisen Schmieren der Lager, die in der Randzone eines schnell umlaufenden scheibenfözmigen Kraftübertragungsgliedes verhältnismäßig großen Durchmessers angeordnet sind, wobei -das Kraftübertragungsglied in einem geschlossenen. teilweise mit Öl angefüllten Gehäuse schnell. umläuft, z. B. eine Vorrichtung zum Schmieren der Lager von Planetenrädern am sogenannten: Tellerrad von Ausgleichgetrieben. _ Die Erfindungsaufgabe wird dadurch gelöst, daB mit dem- teilweise in den . Ölsumpf tauchenden scheibenförmigen Übertragungsglied ein Ölfangring verbunden ist, der durch das von dem Kraftübertragungsglied abgesclileüderte Öl mit Öl versorgt wird,. das sodann in an sich bekannter Weise unter der Wirkung der Fliehkraft den zu schmierenden Lagern in der Randzone des Kraftübertragungsgliedes zugeführt wird.The invention thus relates to a device for forced lubrication the bearings, which are in the edge zone of a fast rotating, disk-shaped power transmission element relatively large diameter are arranged, wherein -the power transmission member in a closed. Housing partially filled with oil quickly. circulates, e.g. B. a device for lubricating the bearings of planetary gears on the so-called: ring gear of differential gears. _ The object of the invention is achieved in that with the partly in the. Oil sump diving disc-shaped transmission member an oil catch ring is connected by the oil cliled off from the power transmission member is supplied with oil. then in a manner known per se under the effect of Centrifugal force the bearings to be lubricated in the edge zone of the power transmission link is fed.

In weiterer. Ausbildung der Erfindung ist vorgesehen, den Ölfangring aus dem Werkstoff des schnell umlaufenden scheibenförmigen Kraftübertragungsgliedes herauszuarbeiten.In further. Formation of the invention is provided, the oil catch ring made of the material of the fast rotating disk-shaped power transmission member to work out.

Die Erfindung ist in der Zeichnung beispielsweise dargestellt, und zwar zeigt .die Abbildung einen Vertikalschnitt durch die erfindungsgemäße Einrichtung. , Das auf der Welle i festsitzende Tellerrad 2 eines Ausglei.chgetriebes taucht mit seinem unteren Teil in einen Ölsumpf 3 ein. Beim Drehen dieses Tellerrades :2 werden auch: die auf seinem Rand verteilt angeordneten Planetenräder q. zwangläufig in den Ölsumpf einsgetaucht. Die den Planetenrädern zugeordneten Gleitläger 5 werden jedoch infolge der sehr hohen Zentrifugalkräfte durch bloßes Eintauchen -der Planetenräder nicht ausreichend geschmiert, weil das anhaftende Öl sofort ab--geschleudert wird. Das Tellerrand- 2 besitzt deshalb eine seitliche Ausnehmung 6,. deren äußerer Rand 7 mittels eines flachen Ringkörpers 8 so überdecktwird, daß eine Ölfangrinne entsteht, in -welcher sich das Ö19 -unter Einwirkung der Fliehkräft fängt. Diese Ölfangrinne steht über einen Kanal iio mit einem im Zapfenlager jedes Planetenrades vorgesehenen Ringkanal ii im, Wirkungsverbindung. - Das. Öl in den Verbindungskanälen io und in .den zugeordneten Ringkanälen i i steht infolge der Fliehkraftwirkung unter Druck,. wodurch die Gleitflächen der Lager der Planetenräder d. ausreichend geschmiert werden.- Diese Druckschmierung ist somit von einem besonderen Druckmittel, wie z. B. einer Ölpumpe, unabhängig.The invention is shown in the drawing, for example, and although the figure shows a vertical section through the device according to the invention. , The ring gear 2 of a gearbox that is stuck on shaft i is immersed with its lower part into an oil sump 3. When turning this ring gear: 2 are also: the planet gears q distributed on its edge. inevitably submerged in the oil sump. The sliding bearings 5 assigned to the planetary gears are However, due to the very high centrifugal forces caused by simply immersing the planetary gears not sufficiently lubricated because the adhering oil is thrown off immediately. The plate rim 2 therefore has a lateral recess 6. their outer edge 7 is covered by means of a flat ring body 8 in such a way that an oil gutter is created, in which the Ö19 catches itself under the influence of centrifugal forces. This oil gutter stands over a channel iio with one provided in the journal bearing of each planet gear Ring channel ii im, functional connection. - That. Oil in the connecting channels OK and in .den associated annular channels i i is under pressure due to the effect of centrifugal force. whereby the sliding surfaces of the bearings of the planetary gears d. be adequately lubricated. This pressure lubrication is thus of a special pressure medium, such as. B. one Oil pump, independent.

Die Erfindung ist überall dort anwendbar, wo gleiche oder gleichartige Verhältnisse vorherrschen.The invention is applicable wherever the same or similar Conditions prevail.
