Description
Die vorliegende Erfindung betrifft eine axiale Wälzlagerung, wie sie insbesondere für die Lagerung von Präzisions NC Rundtischen in Werkzeugmaschinen verwendet werden.The The present invention relates to an axial roller bearing, in particular for the Storage of precision NC rotary tables are used in machine tools.
Bei derartigen Rundtischen können im Betrieb der Werkzeugmaschine unerwünschte Schwingungen auftreten. Diese Schwingungen können zu unerwünschten Vibrationen des Rundtischs und möglicherweise einer fehlerhaften Bearbeitung eines Werkstücks führen. Derartige Schwingungen können über die axiale Wälzlagerung auf andere Maschinenelemente übertragen werden.at such round tables can undesirable vibrations occur during operation of the machine tool. These vibrations can too unwanted Vibrations of the rotary table and possibly lead to incorrect machining of a workpiece. Such vibrations can over the axial rolling bearing transferred to other machine elements become.
Aus
Aufgabe der vorliegenden Erfindung ist es, eine axiale Wälzlagerung anzugeben, die die Übertragung von Schwingungen dämpft bzw. reduziert.task The present invention is to provide an axial roller bearing, the transmission damped by vibrations or reduced.
Erfindungsgemäß ist eine axiale Wälzlagerung vorgeschlagen, mit einem Laufringteil, zu dessen beiden Stirnseiten je ein Gegenlaufringteil angeordnet ist, wobei zwischen dem Laufring und beiden Gegenlaufringteilen jeweils in einem Käfig angeordnete Rollen an Laufbahnen des Laufrings und der Ge genlaufringteile abwälzen, wobei zwischen einander zugewandten Stirnseiten der Käfige und der Gegenlaufringteil jeweils ein mit Dämpfungsflüssigkeit gefüllter Spalt ausgebildet ist.According to the invention is a axial rolling bearing proposed, with a raceway part, to the two end faces each mating ring part is arranged, wherein between the raceway and both mating ring parts each arranged in a cage Rolling rollers on raceways of the race and the Ge genlaufringteile roll, wherein between facing end faces of the cages and the mating ring part one filled with damping fluid gap is trained.
Mit der erfindungsgemäßen axialen Wälzlagerung stellt sich in erwünschter Weise ein sogenannter Squeeze-Effekt ein, mit einer Dämpfung von Schwingungen über den mit Dämpfungsflüssigkeit gefüllten Spalt. Die Übertragung von Schwingungen zwischen dem Laufringteil einerseits und den beiden Gegenlaufringteilen andererseits ist somit deutlich reduziert. Der Käfig ist demzufolge zugleich Teil einer Dämpfungseinrichtung.With the inventive axial roller bearing turns into desirable Induce a so-called squeeze effect, with a damping of vibrations over the filled with damping fluid gap. The transfer of vibrations between the raceway part on the one hand and the two mating raceway parts On the other hand is thus significantly reduced. The cage is therefore at the same time Part of a damping device.
Zusätzlich zu den oben bereits genannten mit Dämpfungsflüssigkeit gefüllten Spalten kann zwischen einander zugewandten Stirnseiten der Käfige und des Laufringteils zusätzlich jeweils ein mit Dämpfungsflüssigkeit gefüllter Spalt ausgebildet sein. Somit ist zu beiden Stirnseiten des Käfigs jeweils ein mit Dämpfungsflüssigkeit gefüllter Spalt vorgesehen, so dass die Übertragung von Schwingungen zwischen dem Laufringteil einerseits und den beiden Gegenlaufringteilen andererseits wirkungsvoll unterbunden ist.In addition to the above-mentioned with damping fluid filled Columns can be between facing end faces of the cages and of the raceway part in addition one with damping fluid filled Be formed gap. Thus, on both faces of the cage respectively one with damping fluid filled Slit provided so that the transmission oscillations between the raceway part on the one hand and the two On the other hand counter rotating ring parts is effectively prevented.
Es wurde herausgefunden, dass eine besonders günstige Dämpfung bzw. besonders wirkungsvolle Unterdrückung einer Schwingungsübertragung bei einer Spaltweite zwischen einschließlich 5 μm bis 30 μm erzielt wird. Der Spalt ist vorzugsweise von planen Flächen begrenzt. Plane Flächen mit der genannten Spaltweite begünstigen in erwünschter Weise den oben bereits erwähnten Squeezeeffekt, da eine große Spaltfläche mit konztanter Spaltweite für die Dämpfung zur Verfügung steht.It It has been found that a particularly favorable damping or particularly effective suppression a vibration transmission at a gap width of between 5 microns to 30 microns is achieved. The gap is preferably of flat surfaces limited. Plane surfaces favor with the mentioned gap width in desired Way the already mentioned above Squeeze effect as a big one cleavage face with a basic gap width for the damping to disposal stands.
Die Gegenlaufringteile und das Laufringteil sind im Bereich der radialen Erstreckung des Käfigs demzufolge vorzugsweise plan ausgebildet.The Counter-rotating ring parts and the raceway part are in the radial Extension of the cage accordingly preferably designed plan.
Die Stirnseiten des Käfigs sind vorzugsweise ebenfalls plan ausgebildet, so dass der Käfig auf einfache Art und Weise beispielsweise aus einer Scheibe mit zueinander planparallelen Stirnseiten gebildet sein kann.The End faces of the cage are preferably also planar, so that the cage on simple way, for example, from a disc with each other can be formed plane-parallel end faces.
Bei der oben erwähnten besonders günstigen Spaltweite ist es zweckmäßig, dass die Käfigstärke annähernd dem Durchmesser der Rollen entspricht. Somit steht nur ein kleiner Raum für Schmiermittel oder Dämpfungsflüssigkeit zur Verfügung. Eine erfindungsgemäße Weiterbildung sieht deshalb vor, dass der Käfig aus einem porösen Material gebildet ist, wobei Poren des Käfigs mit Schmiermittel, bzw. Dämpfungsflüssigkeit gefüllt sind.at the above mentioned especially favorable Slit width, it is appropriate that the cage strength approximately the Diameter of the rolls corresponds. Thus, there is only a small room for lubricants or damping fluid to disposal. An inventive development therefore, provides that the cage from a porous one Material is formed, wherein pores of the cage with lubricant, or damping fluid filled are.
Zur einwandfreien Abdichtung der Spalte kann der Käfig an seinem Innenumfang mit einer Dichtung versehen sein. Verunreinigungen von außen können demzufolge nicht in das Lagerinnere eindringen.to proper sealing of the column can be with the cage on its inner circumference be provided a seal. Consequently, external contamination can occur do not penetrate into the bearing interior.
Nachstehend wird die Erfindung anhand eines in zwei Figuren dargestellten Ausführungsbeispieles näher erläutert. Es zeigenbelow the invention is based on an embodiment shown in two figures explained in more detail. It demonstrate
