Description
Die Erfindung betrifft eine axial angetriebene Kolben-Zylinder-Einheit gemäß dem Oberbegriff des Patentanspruchs 1.The The invention relates to an axially driven piston-cylinder unit according to the generic term of claim 1
Eine
derartige Kolben-Zylinder-Einheit ist beispielsweise aus der
Die
Die
Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße axial angetriebene Kolben-Zylinder-Einheit so auszugestalten, daß die Gefahr einer Zerstörung des Kolbens oder des Zylinders reduziert wird.task The present invention is a generic axial driven piston-cylinder unit in such a way that the danger a destruction of the piston or the cylinder is reduced.
Diese Aufgabe wird durch die im Patentanspruch 1 angegebenen Merkmale gelöst. Eine alternative Lösung ist im Patentanspruch 2 angegeben.These The object is achieved by the features specified in claim 1 solved. An alternative solution is specified in claim 2.
Im normalen Betrieb der Kolben-Zylinder-Einheit ist die Kolbenstange sowohl am Kolben, als auch am Antriebselement exakt festgelegt und es findet keine Relativbewegung zwischen Antriebselement, Kolbenstange und Kolben statt. Erst im Überlastfall, wenn die vom Antriebselement aufgebrachte Kraft die Vorspannkraft der elastischen Einrichtung überschreitet, erfolgt eine Relativbewegung zwischen dem Antriebselement und der Kolbenstange oder zwischen der Kolbenstange und dem Kolben.in the normal operation of the piston-cylinder unit is the piston rod exactly defined both on the piston, and on the drive element and There is no relative movement between the drive element, piston rod and pistons instead. Only in case of overload, when the force applied by the drive element force the biasing force exceeds the elastic device, there is a relative movement between the drive element and the Piston rod or between the piston rod and the piston.
Durch die Entkoppelung der Masse des Antriebselements vom Kolben mittels der elastischen Einrichtung wird das Antriebselement bei einer Bewegung des Kolbens in die Kompressionsstellung von der elastischen Einrichtung dann abgebremst, wenn der Kolben an der kopfseitigen Stirnwand der Zylinderbohrung zur Anlage gekommen ist. Hierdurch trifft nur die Masse des Kolbens gegebenenfalls mit der Masse der Kolbenstange, aber ohne die Masse des Antriebselements auf die kopfseitige Stirnwand der Zylinderbohrung auf. Der dadurch entstehende Stoßimpuls ist gegenüber einer starren Einheit aus Kolben, Kolbenstange und Antriebselement wesentlich geringer, so daß auch die Gefahr der Beschädigung des Kolbenbodens oder der kopfseitigen Stirnwand der Zylinderbohrung deutlich herabgesetzt ist.By the decoupling of the mass of the drive element from the piston by means of the elastic device becomes the driving element during a movement of the piston in the compression position of the elastic device then braked when the piston on the head-side end wall of the cylinder bore has come to the plant. This only affects the mass of the piston possibly with the mass of the piston rod, but without the mass of the drive element on the head-side end wall of the cylinder bore on. The resulting shock pulse is opposite to one rigid unit of piston, piston rod and drive element essential lower, so that too the danger of damage the piston crown or the head-side end wall of the cylinder bore is significantly reduced.
In einer vorteilhaften Ausgestaltung der ersten Lösung ist der Kolbenboden mit einer Öffnung versehen, durch die das erste Ende der Kolbenstange hindurchgeführt ist, wobei die Kolbenstange relativ zum Kolben in Axialrichtung des Kolbens bewegbar ist, wobei die elastische Einrichtung zwischen der Kolbenstange und dem Kolben vorgesehen ist und wobei die elastische Einrichtung die Kolbenstange vom Kolben zur Antriebseinrichtung vorspannt, wobei die Kolbenstange mit einem Endanschlag versehen ist, der verhindert, daß die Kolbenstange aus der Öffnung austritt. Bei dieser Ausgestaltungsform ist die auf die kopfseitige Stirnwand auftreffende Masse noch weiter reduziert, da auch die Masse der Kolbenstange vom Kolben entkoppelt ist.In an advantageous embodiment of the first solution is the piston crown with an opening, through which the first end of the piston rod is passed, wherein the piston rod relative to the piston in the axial direction of the piston is movable, wherein the elastic means between the piston rod and the piston is provided and wherein the elastic means the piston rod biases from the piston to the drive means, wherein the piston rod is provided with an end stop which prevents that the Piston rod out of the opening exit. In this embodiment, the on the head-side Front wall impinging mass even further reduced, as well as the Mass of the piston rod is decoupled from the piston.
Besonders vorteilhaft ist es dabei, wenn die Kolbenstange in der Öffnung abdichtend geführt ist, wozu bevorzugt eine die Kolbenstange umgebende Dichtung vorgesehen ist. Bei dieser Ausgestaltung wird der Kompressionswirkungsgrad verbessert, da das vom Kolben komprimierte Medium nicht durch die die Kolbenstange umgebende Ringspaltöffnung entweichen kann.Especially it is advantageous if the piston rod in the opening sealing guided is, preferably provided for a seal surrounding the piston rod is. In this embodiment, the compression efficiency improved, since the piston-compressed medium is not through the the piston rod surrounding annular gap opening can escape.
Eine vorteilhafte Ausführungsform der alternativen Lösung kennzeichnet sich dadurch, daß das Antriebselement mit einer Öffnung versehen ist, durch die das zweite Ende der Kolbenstange hindurchgeführt ist, daß die Kolbenstange relativ zum Antriebselement in Axialrichtung des Antriebselements bewegbar ist, daß die elastische Einrichtung zwischen der Kolbenstange und dem Antriebselement vorgesehen ist und daß die elastische Einrichtung die Kolbenstange vom Antriebselement zum Kolben vorspannt, wobei die Kolbenstange mit einem Endanschlag versehen ist, der verhindert, daß die Kolbenstange aus der Öffnung austritt. Bei dieser Variante erfolgt die Entkoppelung mittels der elastischen Einrichtung auf der Seite des Antriebselements, so daß zwischen dem Kolben und der Kolbenstange eine feste Verbindung vorgesehen sein kann und eine aufwendige Abdichtung einer Öffnung im Kolbenboden nicht vorgesehen sein muß.An advantageous embodiment of the alternative solution is characterized in that the drive element is provided with an opening through which the second end of the piston rod is passed, that the piston rod is movable relative to the drive element in the axial direction of the drive element, that the elastic means between the piston rod and the drive element is provided and that the elastic means biases the piston rod from the drive element to the piston, wherein the piston rod is provided with an end stop which prevents the piston rod from emerging from the opening. In this variant, the decoupling takes place by means of the elastic means on the side of the drive element, so that a firm connection can be provided between the piston and the piston rod and a complex sealing of an opening in the piston head need not be provided.
Bevorzugterweise weist die elastische Einrichtung eine Feder auf oder ist von einer Feder gebildet. Besonders bevorzugt ist hier das Vorsehen einer Tellerfederanordnung oder einer auf Druck oder Zug belasteten Schraubenfeder.preferably, the elastic device comprises a spring or is of a Spring formed. Particularly preferred here is the provision of a Disc spring arrangement or a loaded on pressure or train coil spring.
Besonders wirksam ist eine Realisierung der vorliegenden Erfindung bei einem Linearantrieb, beispielsweise einem Linearmotor, wobei der Kolben zum hin- und herbewegenden Antrieb von einem beweglichen Antriebselement des Linearantriebs beaufschlagt ist.Especially an implementation of the present invention is effective in a Linear drive, for example, a linear motor, wherein the piston for Floating drive from a movable drive element the linear drive is acted upon.
Eine bevorzugte Anwendung der erfindungsgemäßen axial angetriebenen Kolben-Zylinder-Einheit ist der Einsatz in einem Kompressor zur Erzeugung eines Druckfluids.A preferred application of the axially driven piston-cylinder unit according to the invention is the use in a compressor to produce a pressurized fluid.
