Abstract

The pressure bearing (5) to take up axial shaft forces, does not support directly against rigid surfaces, but against plate springs (6). These springs (6) are between ring nuts (4) and the bearings (5). The springs (6) are both arranged in front of and behind the pressure bearings (5) in the direction of pressure application. A typical application is where a shaft (2) is loaded in a specific direction (3), and via two or more ring nuts (4) presses against two or more axial rib bearings (5). The pressure is then passed on via plate springs (6) and threaded rings (7) screwed into the bearing housing (1).

Description

Mehrfache Drucklagerung.Multiple pressure storage.

Die Erfindung betrifft Drucklager wie aie im Maschinenbau zur Aufnahme axial gerichteter Druckkräfte benötigt werden. The invention relates to thrust bearings such as those in mechanical engineering for receiving axially directed compressive forces are required.

Um solche axialen Druckkräfte von der Welle auf das Lagers gehäuse zu übertragen,wird in bekannter Weise z. B. ein Axial-Rillenkugellager oder ein Axial-Pendelrollenlager ein= gebaut. To such axial compressive forces from the shaft to the bearing housing to transmit is in a known manner, for. B. a thrust ball bearing or a Axial spherical roller bearing installed = installed.

Wenn die Axialdrücke sehr groß sind und evtl. auch noch hohe Drehzahlen vorkommen,treten Lagerüberlastungen auf,die eine baldige Zerstörung des Lagers zur Folge haben.Bisher konnte man dieser vorzeitigen Lagerzerstörung nicht durch Anordnung mehrerer Drucklager begegnen,da dann-wegen der not= wendigen aber nicht erreichbaren Einbaugenauigkeit-,doch nur ein Drucklager die gesamte Druckkraft hätte aufnehmen müssen. If the axial pressures are very high and possibly also high speeds occur, bearing overloads occur, which lead to an early destruction of the bearing Until now, this premature destruction of the camp could not be ordered by order encounter several thrust bearings, because then-because of the necessary but unreachable Installation accuracy - but only one thrust bearing would have to absorb the entire compressive force have to.

Es wäre bald beschädigt gewesen und hätte dann auch noch die Zerstörung der weiteren Drucklager nach sich gezogen.It would soon have been damaged and then it would have been destroyed as well the other thrust bearings.

Der Erfindung liegt die Aufgabe zu Grunde,diesen Nachteil durch eine neuartige Anordnung von zwei oder mehr Drucklagern zu beseitigen. The invention is based on the object of this disadvantage by a to eliminate novel arrangement of two or more thrust bearings.

Diese Aufgabe wurde durch folgende erfindungsgemässen Maßnahmen gelöst: An Stelle eines starr fixierten Abstandes zwischen den Anlagepunkten des Drucklagers gegen die welle und das Lager= gehäuse wird in erfindungsgemäßer Weise ein federndes Zwis schenteil,z. B. eine lellerfeder bekannter Mauart,eingebaut. This object was achieved by the following measures according to the invention: Instead of a rigidly fixed distance between the contact points of the thrust bearing against the shaft and the bearing = housing is a resilient in a manner according to the invention Between part, z. B. a plate spring known Mauart installed.

Auf einer Zeichnung ist ein Ausführungsbeispiel der Erfin dung dargestellt. In a drawing, an embodiment of the inven tion is shown.

Fig. 1 zeigt das Schnittbild durch eine Drucklagerun6 mit mehreren Drucklagern. Fig. 1 shows the sectional view through a Drucklagerun6 with several Thrust bearings.

zine Welle (2) wird in Pfeilrichtung (3) belastet.Über zwei oder mehr Ringmuttern (4) drückt sie gegen zwei oder mehr Axial-Rillenlager (5).Von hier aus wird der Druck über TelleSiedern(6) auf Gewthderinge (7) weitergegeben,die im La-6ergehäuse (1) verschraubt sind. Zine shaft (2) is loaded in the direction of the arrow (3) via two or more ring nuts (4) it presses against two or more thrust groove bearings (5). From here from the pressure is passed on via TelleSiedern (6) to weight rings (7), which are in La-6er housing (1) are screwed.
