Description
Verbindung von Kolben und Kolbenstange Die Erfindung betrifft eine besondere Verbindung des Kolbens mit der zwangsläufig im Zylinder geführten Kolbenstange mittels eines Kardangelenkes.Connection of piston and piston rod The invention relates to a special connection of the piston with the piston rod that is inevitably guided in the cylinder by means of a universal joint.
Der Erfindung gemäße wird die Verbindung so ausgeführt, daß die Kolbenstange um die beiden zueinander senkrechten Achsen nicht nur schwenkbar, sondern Kolben und Kolbenstange in Richtung der beiden Gelenkachsen auch gegeneinander verschiebbar sind, z. B. dadurch, daß die beiden Bolzen des Kardans sich senkrecht aufeinander verschieben können und infolgedessen auch dann keine Betriebsstörungen entstehen können, wenn bei der Montage die Kolbenstange mit der Zylinderachse nicht genau zusammenfällt. Dies ist insbesondere bei Steuerzylindern, sog. Servomotoren, von besonderer Bedeutung, weil erfahrungsgemäß bei diesen ein genaues Zusammenfallen der Zylinderachse und der Deckelachse erschwert, in vielen Fällen überhaupt nicht zu erreichen ist. In solchen Fällen wäre es mit der bekannten Anwendung eines Kardangelenkes an sich allein nicht getan.According to the invention, the connection is carried out so that the piston rod Not only pivotable about the two mutually perpendicular axes, but also pistons and piston rod can also be displaced against one another in the direction of the two joint axes are e.g. B. in that the two bolts of the cardan are perpendicular to each other can move and as a result, no operational disruptions arise can if the piston rod is not exactly aligned with the cylinder axis during assembly coincides. This is particularly important in the case of control cylinders, so-called servomotors of particular importance, because experience has shown that these coincide exactly the cylinder axis and the cover axis difficult, in many cases not at all can be achieved. In such cases it would be with the known use of a universal joint not done in and of itself.
Die Zeichnung veranschaulicht ein Ausführungsbeispiel des Erfindungsgegenstandes an Hand eines Steuerzylinders, und zwar zeigt Abb. i einen Längsschnitt durch den Zylinder und Abb. 2 einen Schnitt gemäß II-II der Abb. i.The drawing illustrates an embodiment of the subject matter of the invention on the basis of a control cylinder, namely Fig. i shows a longitudinal section through the Cylinder and Fig. 2 a section according to II-II of Fig. I.
Bei dem dargestellten Beispiel ist die Kolbenstange i in den Deckel a geführt. Die Führung ist verhältnismäßig läng ausgebildet und in üblicher Weise außen zur Aufnahme einer Stopfbüchse 3 eingerichtet. Der Kolbenstangenkopf q. am inneren Ende der Kolbenstange i hat eine Bohrung zur unmittelbaren Aufnahme des einen Gelenkzapfens 5. Dieser ist an dem Kopf 4 drehbar und längs verschiebbar geführt. Der zweite Gelenkzapfen 6 ist in einer Bohrung des ersten Zapfens 5 eingesetzt, und zwar so, daß er sich in dem Zapfen 5 sowohl drehen als auch in Längsrichtung verschieben kann. Damit in dem praktisch in Betracht kommenden Bereich der Kolbenstangenkopf 4 bei seiner Drehung um den ersten Gelenkzäpfen 5 nicht gestört wird; ist genügend Spie17 zwischen dem zweiten Zapfen 6 und dem Kolbenstangenkopf 4 vorgesehen. Die beiden Enden des zweiten Gelenkzapfens 6 sind in üblicher Weise in dem Kolben 8 gelagert. Der erste Gelenkzapfen 5 wird gegen Herausrutschen aus dem Kolbenstangenkopf 4 von dem zweiten Gelenkzapfen 6 gehalten, ohne in seiner Beweglichkeit behindert zu sein:In the example shown, the piston rod i is in the cover a led. The guide is made relatively long and in the usual way set up outside to accommodate a stuffing box 3. The piston rod head q. at the inner end of the piston rod i has a bore for the immediate reception of the a pivot pin 5. This is guided on the head 4 so as to be rotatable and longitudinally displaceable. The second pivot pin 6 is inserted into a bore of the first pin 5, in such a way that it rotates in the pin 5 as well as in the longitudinal direction can move. This means that the piston rod head is in the practically relevant area 4 is not disturbed in its rotation about the first pivot pin 5; is sufficient Spie17 is provided between the second pin 6 and the piston rod head 4. the Both ends of the second pivot pin 6 are in the piston 8 in the usual manner stored. The first pivot pin 5 is prevented from slipping out of the piston rod head 4 held by the second pivot pin 6 without being hindered in its mobility to be:
