Description

Schmiervorrichtung für Kegelradachsgetriebe in Schienenfahrzeugen mit Gelenkwellenantrieb hegelradachsgetriebe, die sowohl bei Starrahmenz als auch bei Drehgestellokomotiv en mit Gelenkwellenantrieb verwendet werden, sind infolge, ihrer Anordnung zwischen den Radscheiben und innerhalb des Fahrzeug- bzw. Drehgestellrahmens schlecht zugänglich. Da hierdurch auch eine gute Beobachtung ausgeschlossen sowie demzufolge die Pflege und Wartung oft nicht ausreichend sind, darf ein solches Getriebe nicht störanfällig sein. Wichtig ist vor allem auch eine unbedingt sichere und ausreichende Schmierung, insbesondere an den Lagerstellen.Lubricating device for bevel gears in rail vehicles with cardan shaft drive Hegelradachsträger, which are used with both Starrahmenz and are used in bogie locomotives with cardan shaft drive, are due to their arrangement between the wheel disks and within the vehicle or bogie frame poorly accessible. Because this also ruled out a good observation as well as a result, the care and maintenance are often insufficient, such a transmission is allowed not be prone to failure. Above all, it is important to have an absolutely safe and sufficient one Lubrication, especially at the bearing points.

Bei geringeren Leistungen und einfachen Bauarten hat man sich bisher mit Vorrichtungen zur Tauchschmierung begnügt, bei denen ein sich drehendes Rad in den Ölsumpf taucht und das von diesem abspritzende Öl durch im Gehäuseoberteil angeordnete Öltaschen aufgefangen wird, um dann durch Leitungen unter Schwerkraftwirkung zu den Schmierstellen hindurchgeführt zu werden. Bei größeren Leistungen ist es bekannt, für die Schmierung eine Ölpumpe zu verwenden, die aus dem Ölsumpf heraus alle Lagerstellen und Räder schmiert. Auch Verbundschmierungen sind bekannt, bei denen die Schmierung der Lager und Räder vom Achsgetriebe aus sowohl durch die Schaufelwirkung eines in den Ölsumpf tauchenden Zahnrades als auch durch eine in beiden Drehrichtungen fördernde Ölpumpe erfolgt, die auf den gleichen Schmierölkreislauf fördert.In the case of lower performances and simple designs, one has so far content with devices for splash lubrication in which a rotating wheel immersed in the oil sump and the oil sprayed off by it through the upper part of the housing arranged oil pockets is collected, to then through pipes under the action of gravity to be passed through to the lubrication points. In the case of greater achievements, it is known to use an oil pump for lubrication, which comes out of the oil sump lubricates all bearings and wheels. Composite lubrication is also known which the lubrication of the bearings and wheels from the axle drive through both the paddle effect a gear that plunges into the oil sump as well as one in both directions of rotation conveying oil pump takes place, which promotes on the same lubricating oil circuit.

Die Erfindung betrifft eine Schmiervorrrichtung für eine derartige Verbundschmierung und besteht in erster Linie darin, daß im Oberteil des Getriebegehäuses eine oder mehrere miteinander verbundene, das Spritzöl vom tauchenden Rad auffangende und durch Leitungen unter Schwerkraftwirkung zu den verschiedenen Schmierstellen abführende Öltaschen angeordnet sind, wobei die Ölpumpe auf den gleichen Schmierölkreislauf fördert.The invention relates to a lubricating device for such a device Composite lubrication and consists primarily in that in the upper part of the gearbox housing one or more interconnected, collecting the splash oil from the submerged wheel and through lines under the action of gravity to the various lubrication points Discharge oil pockets are arranged, the oil pump on the same lubricating oil circuit promotes.

Die hiermit vorgeschlagene besondere Anordnung der bekannten Verbundschmierung bietet die Gewähr, daß auch bei möglichem Versagen einzelner Elemente keine Schmierstelle sogleich unter Ölmangel zu leiden hat, so daß in solchen Fällen keine Beschädigung, # sondern allenfalls eine geringfügige, vorübergehend zulässige Erwärmung auftreten kann.The special arrangement of the known composite lubrication proposed hereby offers the guarantee that even if individual elements fail, there will be no lubrication point immediately has to suffer from a lack of oil, so that in such cases no damage, # but at most a slight, temporarily permissible temperature rise can.

Zweckmäßig mündet die Druckleitung der Ölpumpe in eine Verbindungsleitung zwischen einer Öltasche und der Schmierstelle eines Lagers, und zwar vorzugsweise dicht oberhalb eines hinsichtlich der Schmierung besonders empfindlichen Lagers, z. B. des den Axialschub des Kegelritzels aufnehmenden Kegelrollenlagers.. Außerdem kann dieAnordnung.d'e,rDruckleitung so getroffen werden, daß bei Versagen der Pumpe ein Abfluß des Öles von den ölta,schen durch die Druckleitung zur Pumpe zurück nicht möglich ist. Die genannten und andere Merkmale der- Erfindung sind an Hand eines Ausführungsbeispiels in der Zeichnung schematisch dargestellt und nachstehend hinsichtlich Aufbau und Wirkungsweise erläutert. Im einzelnen zeigt Fig. 1 einen lotrechten Schnitt in: Fahrzeuglängsrichtung nach der Linie I-I der Fig. 2 und Fig. 2 einen Querschnitt nach der Linie II-II der Fig. 1.The pressure line of the oil pump expediently opens into a connecting line between an oil pocket and the lubrication point of a bearing, preferably just above a bearing that is particularly sensitive to lubrication, z. B. the tapered roller bearing absorbing the axial thrust of the bevel pinion .. In addition the arrangement of the pressure line can be made so that if the pump fails There is no drainage of the oil from the oil bags through the pressure line back to the pump is possible. The above and other features of the invention are based on one Exemplary embodiment shown schematically in the drawing and below with regard to Structure and mode of operation explained. In detail, Fig. 1 shows a vertical section in: the longitudinal direction of the vehicle along the line I-I in FIGS. 2 and 2, a cross section according to the line II-II of FIG. 1.

Von einer am Flansch 1 angreifenden, nicht dargestellten Kardanwelle aus wird das auf der Welle 2 sitzende Kegelritzel 3 angetrieben, das mit dem auf der Radsatzwelle 5 angeordneten großen Kegelrad 4 kämmt.From a cardan shaft, not shown, engaging the flange 1 from the seated on the shaft 2 bevel pinion 3 is driven, which with the on the wheelset shaft 5 arranged large bevel gear 4 meshes.

Das Getriebegehäuse ist in Höhe der Achswellenmitte geteilt. Sein Unterteil 6 ist als Ölsumpf aus-, gebildet, in den das große Kegelrad 4 ständig eintaucht. Im Oberteil 7 sind durch Einschweißen von Blechen_öltaschen 8, 9, 10 und 11 angeordnet, die sämtlich miteinander in Verbindung stehen und in die das vom tauchenden Rad 4 gegen die Gehäusedecke 12 gespritzte Öl in Richtung der Pfeile 13 und 14 abläuft. Die Öltaschen sind so. angeordnet, d'aß in beiden Fahrtrichtungen ausreichend Öl aufgefangen wird. Zur Verbesserung der Tauchschmierung kann das tauchende Rad 4 noch eine Schleuderspritze 23 aufweisen.The gearbox housing is divided at the level of the center of the axle shaft. being Lower part 6 is designed as an oil sump, formed into which the large bevel gear 4 is constantly immersed. In the upper part 7 are sheet metal oil pockets 8, 9, 10 and 11, all of which are in communication with each other and in which the from the diving wheel 4 against the housing cover 12 sprayed oil in the direction of the arrows 13 and 14 expires. The oil pockets are like that. arranged, d'ass in both directions sufficient oil is collected. To improve the immersion lubrication, the submerged Wheel 4 also have a centrifugal syringe 23.

Von den Öltaschen fließt das Öl unter Schwerkraftwirkung zu den verschiedenen Schmierstellen ab, und zwar über die Leitungen 15 zu den Lagern 16 und 17, über die Leitung 18 zum Lager 19, über die Leitung 20 zum Lager 21 und über die Leitung-22 zum Zahneingriff zwischen den Kegelrädern 3 und 4. Aus der Öltasche 8 führt ferner noch die Verbindungsleitung 24 zu den besonders empfindlichen Kegelrollenlagern 25 und 26. Das Öl wird diesen Lagern von außen über die Bohrungen 27 und 28 zu- und von ihnen durch die Leitung 29 hindurch in den Sumpf abgeführt.From the oil pockets, the oil flows under the action of gravity to the various lubrication points, via the lines 15 to the bearings 16 and 17, via the line 18 to the bearing 19, via the line 20 to the bearing 21 and via the line 22 for tooth engagement between the bevel gears 3 and 4. The connecting line 24 also leads from the oil pocket 8 to the particularly sensitive tapered roller bearings 25 and 26. The oil is fed to these bearings from the outside via the bores 27 and 28 and from them through the line 29 into drained the swamp.

Von einer Ölpumpe 30, die über das Zahnrad 31 von dem Zahnkranz 32 auf der Achswelle 5 angetrieben wird, führt die Druckleitung 33 über den Stutzen 34 in die zuletzt genannte Verbindungsleitung 24. Der Stutzen 34 liegt oberhalb des höchsten Ölstandes in den Öltaschen, so daß bei etwaigem Versagen der Pumpe 30 kein Öl aus den Öltaschen über die Leitung 33 zur Pumpe zurückfließen kann.From an oil pump 30, which is driven by the ring gear 32 via the gear 31 is driven on the axle shaft 5, the pressure line 33 leads over the nozzle 34 into the last-mentioned connecting line 24. The connecting piece 34 lies above the highest oil level in the oil pockets, so that in the event of a pump failure 30 no oil can flow back from the oil pockets via line 33 to the pump.

Der den Ölbehälter bildende Unterteil 6 des Gehäuses ist durch eine bekannte Überlaufwand 35 in zwei Räume getrennt. Der Raum 36 unterhalb des Rades 4 dient als Ölbehälter für die Tauchschmierung, während aus dem daneben gelegenen Teil 37 die Saugleitung 38 zur Ölpumpe 30 führt. Bei normalem Betrieb ist der Raum 37 bis zur Oberkante der Überlaufwand 35 gefüllt, während der Raum 36 einen niedrigeren Ölstand aufweist, da das Rad 4 je nach Drehrichtung über die Kanten 39 oder 40 däs Öl herausschaufelt. Nur bei Stillstand sowie bei leeren Öltaschen und Schmierleitungen sind beide Räume 36 und 37 gleich hoch gefüllt.The lower part 6 of the housing forming the oil container is through a known overflow wall 35 separated into two rooms. The space 36 below the wheel 4 serves as an oil reservoir for the splash lubrication, while the one next to it Part 37 leads the suction line 38 to the oil pump 30. During normal operation, the room is 37 filled to the upper edge of the overflow wall 35, while the space 36 is a lower one Has oil level, since the wheel 4 depending on the direction of rotation over the edges 39 or 40 däs Scooping out oil. Only when the machine is at a standstill and when the oil pockets and lubrication lines are empty Both rooms 36 and 37 are filled to the same extent.

Mit dem dargestellten Getriebe ist eine doppelte Schmierung an den Schmierstellen sichergestellt. Versagt z. B. die Ölpumpe, so werden alle Schmierstellen auch durch die Tauchschmierung allein versorgt. Arbeitet andererseits die letztere, z. B. infolge Ölmangels, nicht ausreichend, so schmiert die Ölpumpe allein zunächst die empfindlichsten Lager und danach mit steigender Drehzahl über die Öltaschen: auch die übrigen Schmierstellen. Damit die letztgemannten auch: beim Anfahren, nicht ohne Schmierung sind, können bekannte Staukanten od. dgl. in sodch:er Höhe angebracht werden, daß die Außenringe der Lager 16 und 17 ständig mit Öl benetzt sind.With the gear shown, a double lubrication is to the Lubrication points ensured. Failed z. B. the oil pump, all lubrication points are also supplied by the splash lubrication alone. On the other hand, does the latter work z. B. due to lack of oil, not sufficient, so the oil pump lubricates alone initially the most sensitive bearings and then with increasing speed via the oil pockets: also the other lubrication points. So that the latter also: when starting, not are without lubrication, known damming edges or the like can be attached at a height be that the outer rings of the bearings 16 and 17 are constantly wetted with oil.

Um die doppelt geschmierten Lager 25 und 26 nicht zu überfluten, wird zweckmäßig zur Begrenzung der Zulaufmenge hinter der Vereinigungsstelle 42 der Leitungen 33 und 24, wie bekannt, eine Blende 43 vorgesehen.In order not to flood the double-lubricated bearings 25 and 26 expedient to limit the flow rate behind the junction 42 of the lines 33 and 24, as is known, a diaphragm 43 is provided.

Die Erfindung ist nicht auf das dargestellte Beispiel beschränkt, sondern beispielsweise auch dann anwendbar, wenn dem Kegelradgetriebe zur Vergrößerung der Übersetzung noch eine Stirnradstufe vor- oder nachgeschaltet ist.The invention is not limited to the example shown, but also applicable, for example, when the bevel gear for enlargement the translation is preceded or followed by a spur gear stage.

Anspruch 1 schützt lediglich die Gesamtkombination der sämtlichen Erfindungsmerkmale. Die Ansprüche 5 und 6 sind reine Unteransprüche und gelten nur in Verbindung mit Anspruch 1.Claim 1 only protects the overall combination of all of them Features of the invention. Claims 5 and 6 are pure subclaims and only apply in connection with claim 1.
