Abstract
Description
Die Erfindung betrifft eine Einrichtung zur Verteilung von Schmiermittel in einem Axiallager nach dem Oberbegriff von Anspruch 1 und 6.The The invention relates to a device for distributing lubricant in a thrust bearing according to the preamble of claim 1 and 6.

Die
Der Erfindung liegt die Aufgabe zu Grunde, die Schmiermittel-Verteilung bei einem Axiallager zu verbessern.Of the Invention is based on the object, the lubricant distribution at a To improve thrust bearings.
Die Aufgabe wird durch die Merkmale von Anspruch 1 und Anspruch 6 gelöst. Die Ausgestaltungen sind in den Unteransprüchen dargestellt.The The object is solved by the features of claim 1 and claim 6. The Embodiments are shown in the subclaims.
In einer ersten Ausführungsform der Erfindung ist für ein Axiallager mit radial verlaufender Nut und u-förmiger Kontur gegenüber der Welle vorgesehen, dass ein Steuerring auf der Welle angeordnet ist. Der Steuerring zur Schmiermittel-Verteilung greift in die Nut in der Art ein, dass ein Schmiermittel-Volumenstrom auf die belastete Lagerseite gelenkt wird und auf der unbelasteten Lagerseite abgedrosselt oder abgesperrt wird. Hierzu ist am Steuerring ein Dichtsteg zur Anlage an die Nut vorgesehen. Der Steuerring ist drehfest bzw. als geschlitzter Kolbenring axial verschiebbar auf der Welle angeordnet.In a first embodiment the invention is for a thrust bearing with radial groove and U-shaped contour across from the shaft provided that a control ring is arranged on the shaft. The control ring for lubricant distribution engages the groove in the way that a lubricant volume flow is directed to the loaded bearing side and on the unloaded Store side throttled or shut off. This is on the control ring a sealing ridge provided for engagement with the groove. The tax ring is non-rotatable or axially slidable as slotted piston ring arranged the shaft.
In einer zweiten Ausführungsform der Erfindung ist das Axiallager drehfest auf der Welle angeordnet und hat eine trapezförmige Nut. Der Steuerring ist fest mit der Wand verbunden, wobei dieser zur Schmiermittel-Verteilung in die trapezförmige Nut des Axiallagers in der Art eingreift, dass ein Schmiermittel-Volumenstrom auf die belastete Lagerseite gelenkt wird und auf der unbelasteten Lagerseite abgedrosselt oder abgesperrt wird.In a second embodiment the invention, the thrust bearing is rotatably mounted on the shaft and has a trapezoidal shape Groove. The control ring is firmly connected to the wall, this being for lubricant distribution in the trapezoidal groove of the thrust bearing in engages the type that a lubricant volume flow on the loaded Bearing side is steered and throttled on the unloaded bearing side or shut off.
Die Erfindung bietet insgesamt den Vorteil, dass durch den axialen Weg der Welle die Schmiermittel-Steuerspalte so verändert werden, dass der Schmiermittel-Volumenstrom bevorzugt auf die belastete Lagerseite gelenkt wird. Die unbelastete Lagerseite wird abgedrosselt bzw. abgesperrt. Eine zusätzliche axiale Dichtwirkung zur unbelasteten Lagerseite ergibt sich durch den hydraulischen Druck im Steuerspalt der belasteten Lagerseite bei axial verschiebbarem Steuerring. Indem als Steuerring ein geschlitzter Kolbenring verwendet wird, kann das Axiallager einteilig ausgeführt werden. Hieraus resultiert eine verbesserte Montage. Ganz allgemein bietet die Erfindung den Vorteil, dass die Schmierung und Kühlung durch eine gesteuerte Schmiermittel-Zufuhr zur belasteten Lagerseite eindeutig verbessert wird. Gleichzeitig kann der Schmiermittel-Förderstrom reduziert werden.The Invention has the overall advantage that by the axial path the shaft, the lubricant control column are changed so that the lubricant flow rate preferably is directed to the loaded bearing side. The unloaded Bearing side is throttled or shut off. An additional Axial sealing effect for unloaded bearing side results from the hydraulic pressure in the control gap of the loaded bearing side with axially displaceable control ring. As a control ring a slotted Piston ring is used, the thrust bearing can be made in one piece. This results in an improved assembly. Generally offers the invention has the advantage that the lubrication and cooling by a controlled lubricant supply to the loaded bearing side clearly is improved. At the same time, the lubricant flow rate be reduced.
