Description

Vorrichtung zur weichen und elastischen Lagerung hochtourig umlaufender Wellen mit etwa gleichbleibender Axialbelastung Die Erfindung bezieht sich auf eine Vorrichtung zur elastischen Lagerung von hochtourigen Wellen unter Verwendung eines Druckmittelraumes zur Ausbildung eines hydraulischen Polsters, wobei der Druckmittelraum ständig von Druckmittel durchströmt wird und das Lagerspiellos in einem inneren Lagerträger gehalten ist, welcher von einem äußeren Ringflansch in zwei zylindrische Abschnitte aufgeteilt ist, wobei der Ringflansch in eine Aussparung eines äußeren Lagerkörpers hineinragt und zwischen dem Ringflansch und jeweils einem zylindrischen Abschnitt des Lagerträgers einerseits und dem äußeren Lagerträger andererseits zwei Druckmittelteilkammern gebildet werden, die an ihren axial äußeren Enden durch Dichtungsringe abgegrenzt und am Außenumfang des Ringflansches gegeneinander abgedichtet sind. Device for soft and elastic storage of high-speed revolving Shafts with an approximately constant axial load. The invention relates to a Device for the elastic mounting of high-speed shafts using a Pressure medium space to form a hydraulic cushion, the pressure medium space is constantly flowed through by pressure medium and the bearing without play in an interior Bearing carrier is held, which is cylindrical from an outer annular flange into two Sections is divided, the annular flange in a recess of an outer Bearing body protrudes and between the annular flange and a cylindrical each Section of the bearing bracket on the one hand and the outer bearing bracket on the other hand, two Pressure medium sub-chambers are formed at their axially outer ends by sealing rings are delimited and sealed against each other on the outer circumference of the annular flange.

Diese Ausführung bietet zwar die Möglichkeit, ein Lager mit axialer und radialer Wechselbelastung, wie z.B. Schwingungen so auszubilden, daß diese Schwingungen auf erträgliche Werte gedämpft werden, jedoch ist sie noch mit dem Nachteil behaftet, daß bei Lagern mit einseitig gerichteter axialer Grundbelactung der sich radial nach au3en in die Aussparung des Gehäuseteils erstreckende Ringflansch infolge der Grundbelastung an die eine seitliche Wand der Aussparung anlegt und dabei erstens seine Dämpfungsfähigkeit weigehend verliert und zweitens durch die radialen Vibrationen ein unerwünschter Verschleiß an dieser Seitenwand auftritt.Although this version offers the possibility of a bearing with an axial and radial alternating loading, such as vibrations so that these vibrations subdued to bearable values but it is still with has the disadvantage that in bearings with unidirectional axial Grundbelactung the annular flange extending radially outward into the recess of the housing part due to the base load on one side wall of the recess and firstly loses its damping ability and secondly because of the radial vibrations an undesirable wear occurs on this side wall.

Aufgabe der vorliegenden Erfindung ist es, bei einem Lager mit axialer Grundbelastung die axiale Anlage des Ringflansches zu vermeiden und damit auch unter diesen Bedingungen die volle Dämpfungsfähigkeit des Lagers und damit dessen Lebensuauer zu erhöhen.The object of the present invention is, in a bearing with an axial Basic load to avoid the axial contact of the annular flange and thus also under under these conditions the full damping capacity of the camp and thus its lifespan to increase.

Die Lösung dieser Aufgabe besteht erfindungsgemäß darin, daß der Außendurchmesser eines zylindrischen Abschnitts des inneren Lagerträgers zur Vergrößerung der axialen Stirnfläche der betreffenden Druckmittelteilkammer geringer ist als der andere und fur beide Teilkammern eine gemeinsame Druckölzufuhr ud gemeinsame Abflußleitung vorgesehen ist. Dadurch wird die Hydraulisch wirksame Fläche auf dieser Seite erhoht, wobei die axiale Grundlast ebenfalls kompensiert werden kann, ohne daß Druckölzufuhr mit verschiedenen Drücken und verschiedenen Leitungen erforderlich wäre.According to the invention, this object is achieved in that the outer diameter a cylindrical portion of the inner bearing bracket to enlarge the axial The end face of the relevant pressure medium sub-chamber is smaller than the other and A common pressure oil supply and common drain line for both sub-chambers is provided. This increases the hydraulically effective area on this side, whereby the axial base load can also be compensated without the supply of pressurized oil with different pressures and different lines would be required.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, nämlich ein Lager mit unterschiedlichen hydraulisch wirksamen Flächen auf beiden Seiten des Radialflansches.In the drawing, an embodiment of the invention is shown, namely a bearing with different hydraulically effective areas on both Sides of the radial flange.

Dieses Lager hat unterschiedlich große hydraulisch wirksame Flächen, welche durch beiderseits des Radialflansches vorgesehene verschiedene Außendurchmesser 23, 24 des inneren Lagerträgers 25 erhalten werden und eine gemeinsame Druckölzufuhr 18 für beide Teilkammern, ebenso wie eine gemeinsame Rücklaufleitung 19, in der auch ein Drosselventil 22 eingebaut sein kann.This bearing has hydraulically effective areas of different sizes, which are provided by different outer diameters on both sides of the radial flange 23, 24 of the inner bearing bracket 25 are obtained and a common pressure oil supply 18 for both sub-chambers, as well as a common return line 19 in the a throttle valve 22 can also be incorporated.

Bei dieser Ausführung kann die radiale Dichtung lo entfallen und an ihrer Stelle ein engeres Radialspiel entsprechend dem Radialspiel zwischen den Außendurchmessern der beiden zylindrischen Abschnitte und den dazugehörigen Bohrungsdurchmessern treten.In this embodiment, the radial seal lo can be omitted and on their place a tighter radial play corresponding to the radial play between the outer diameters of the two cylindrical sections and the associated bore diameters.
