Description

Gebiet der ErfindungField of the invention

Die vorliegende Erfindung betrifft eine axiale Wälzlagerung, wie sie insbesondere für die Lagerung von Präzisions NC Rundtischen in Werkzeugmaschinen verwendet werden. The present invention relates to an axial rolling bearing, as they especially for the storage of precision NC rotary tables in machine tools be used.

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. Aufgabe der vorliegenden Erfindung ist es, eine axiale Wälzlagerung anzugeben, die die Übertragung von Schwingungen dämpft bzw. reduziert. In such round tables can in operation of the machine tool unwanted vibrations occur. These vibrations can too unwanted vibrations of the rotary table and possibly a faulty one Machining a workpiece lead. Such vibrations can over the axial rolling bearing are transferred to other machine elements. Object of the present invention is an axial rolling bearing specify that dampens or reduces the transmission of vibrations.

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 Gegenlaufringteile abwälzen, wobei zwischen einander zugewandten Stirnseiten der Käfige und der Gegenlaufringteil jeweils ein mit Dämpfungsflüssigkeit gefüllter Spalt ausgebildet ist. According to the invention, an axial roller bearing is proposed, with a Raceway part, arranged on the two end faces depending on a mating ring part is, wherein between the raceway and both mating ring parts respectively in a cage arranged rollers on raceways of the race and the Roll counter-rotating ring parts, wherein between facing end faces the cages and the mating ring each with a damping fluid filled gap is formed.

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 axial rolling bearing according to the invention turns into desirable Do a so-called squeeze effect, with a damping of Vibrations over the gap filled with damping fluid. The transfer oscillations between the raceway part on the one hand and the two Countercurrent ring parts on the other hand is thus significantly reduced. The cage is Consequently, 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 filled with damping fluid Columns may be between facing end faces of the cages and the Laufringteils additionally each filled with damping fluid gap be educated. Thus, on each of the front sides of the cage one with Damping fluid filled gap provided so that the transmission of Vibrations 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 konstanter Spaltweite für die Dämpfung zur Verfügung steht. It has been found that a particularly favorable damping or Particularly effective suppression of vibration transmission in a Gap between 5 microns to 30 microns is achieved. The gap is preferably bounded by flat surfaces. Plane surfaces with the mentioned Gap width favor desirably the above already mentioned Squeeze effect, since a large gap area with constant gap width for the Damping is available.

Die Gegenlaufringteile und das Laufringteil sind im Bereich der radialen Erstreckung des Käfigs demzufolge vorzugsweise plan ausgebildet. The mating ring parts and the raceway part are in the radial Extension of the cage therefore 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 likewise flat, so that the cage in a simple manner, for example, from a disc may be formed with mutually 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. In the case of the above-mentioned particularly favorable gap width, it is expedient that the cage thickness corresponds approximately to the diameter of the rollers. Thus There is only a small space for lubricant or damping fluid Available. A development of the invention therefore provides that the Cage is formed of a porous material, wherein pores of the cage with Lubricant, or damping fluid are filled.

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. For perfect sealing of the column, the cage on his Inner circumference should be provided with a seal. Pollution from the outside can Consequently, do not penetrate into the camp interior.
