Description
Bezeichnung: Sicherung für einen in GewindeeingriffDesignation: Fuse for one in thread engagement
mit einer Kolbenstange stehenden Kolben Zusatz zu DBP (Patentanmeldung P 31 30 998.4-12) Beschreibung Die Erfindung betrifft eine Sicherung gemäß dem Oberbegriff des Patentanspruches 1.Piston standing with a piston rod Addition to DBP (patent application P 31 30 998.4-12) Description The invention relates to a fuse according to the preamble of claim 1.
Der Gegenstand dieser Erfindung bildenden Ausgestaltung einer solchen Sicherung liegt in erster Linie die Aufgabe zugrunde, dazu beizutragen, daß die Sicherung immer eingebaut wird. Diese Aufgabe stellt sich insbesondere im Hinblick darauf, daß die Zuordnung des Kolbens zur Kolbenstange, etwa im Anschluß an eine Kolbenreparatur, auch von Nicht-Fachleuten vorgenommen werden muß, die den Einbau der Sicherung leicht übersehen.The object of this invention forming such a The primary objective of safeguarding is to help ensure that the Fuse is always built in. This task arises in particular with regard to ensure that the assignment of the piston to the piston rod, for example following a Piston repair, even by non-specialists, has to do the installation easily overlooked by the fuse.
Die Aufgabe wird mit einer Sicherung der Eingangs umrissenen Art gelöst, die erfindungsgemäß entsprechend den Merkmalen des kennzeichnenden Teiles des Patentanspruches 1 ausgestaltet ist.The task is solved with a backup of the type outlined at the beginning, according to the invention according to the features of the characterizing part of claim 1 is designed.
Die Kolben.Kolbenstangen-Sicherung nach der Erfindung erfordert den Einbau von zwei Sicherungsteilen, nämlich dem mit einer Längsbohrung versehenen eigentlichen Sicherungsstift und dem in die Bohrung des Sicherungsstiftes einzuziehenden Sicherungsdraht, wodurch das Unterlassen des Sicherungseinbaues offensichtlicher wird als durch einen Sicherungsstift allein.The Kolben.Kolbenstangen fuse according to the invention requires the Installation of two securing parts, namely the one provided with a longitudinal hole actual Locking pin and the one in the hole of the locking pin safety wire to be pulled in, which makes the failure to install the fuse more obvious is considered by a locking pin alone.
Mit dem in den Sicherungsstift eingezogenen Draht, dessen überstehende Enden gegen den Kolben abgebogen werden ist der weitere Vorteil verbunden, daß ein solchermaßen gesicherter Sicherungsstift sich auch dann nicht löst, wenn der Sicherungsstift im Kolben und in der Kolbenstange aufgrund von Bearbeitung stoleranzen Spiel hat.With the wire pulled into the locking pin, its protruding Ends bent against the piston is the further benefit of having a connected securing pin secured in this way does not come loose even if the securing pin has tolerance clearance in the piston and in the piston rod due to machining.
Einer bevorzugten Ausführungsform gemäß ist der den Sicherungsbereich bildende Kolbenansatz in der Ebene der Querbohrung für den Sicherungsstift mit einer Ringnut versehen, in die sich die abgebogenen Enden des in den Sicherungsstift eingezogenen Drahtes einfügen.According to a preferred embodiment, this is the security area forming piston approach in the plane of the cross hole for the locking pin with a Provided annular groove into which the bent ends of the retracted in the locking pin Insert wire.
In der Zeichnung ist die Erfindung anhand eines Ausführungsbeispieles weitergehend erläutert. Es zeigen: Figur 1 einen Längsschnitt durch eine Kolben-Kolbenstangen-Verbindung mit erfindungsgemäß ausgestalteter Sicherung, Figur 2 einen Schnitt nach Linie II - II in Figur 1.In the drawing, the invention is based on an exemplary embodiment further explained. The figures show: FIG. 1 a longitudinal section through a piston-piston rod connection with a fuse designed according to the invention, Figure 2 is a section according to line II - II in Figure 1.
Zur Sicherung des in Gewindeeingriff mit der Kolbenstange 11 stehenden Kolbens 12 auf der Kolbenstange 11 ist die Kolbenstange 11 mit einem eine Ringnut 112 aufweisenden Ansatz 113 versehen und der Kolben 12 mit einem eine tangential in die Ringnut 112 im Kolbenstangenansatz 111 auslaufende Querbohrung 122 aufweisenden, gegenüber dem Kolben 12 abgesetzten Ansatz 121.To secure the threaded engagement with the piston rod 11 Piston 12 on the piston rod 11 is the piston rod 11 with an annular groove 112 having projection 113 and the piston 12 with a tangential having transverse bore 122 running out into the annular groove 112 in the piston rod attachment 111, Extension 121 offset in relation to piston 12.
Zur Sicherung des Kolbens 12 auf der Kolbenstange 11 wird in die Querbohrung 122 im Kolbenansatz 121 ein mit einer Längsbohrung 311 versehener, sich durch die Ringnut 112 im Kolbenstangenansatz 111 erstreckender Sicherungsstift 31 getrieben und durch den eingetriebenen Sicherungsstift 31 ein Stahldraht 32 mit beidseitigen Überständen 321,321' eingezogen sowie die beidseitigen Überstände 321,321' des Drahtes 32 gegen den Kolben 12 bzw. den Kolbenansatz 121 abgebogen, wobei sie sich in die am Umfang des Kolbenansatzes 121 vorgesehene Ringnut 123 einfügen.To secure the piston 12 on the piston rod 11, the transverse bore is used 122 in the piston attachment 121 provided with a longitudinal bore 311, through the Ring groove 112 in the piston rod attachment 111 extending locking pin 31 driven and through the driven-in locking pin 31, a steel wire 32 with both sides Overhangs 321,321 'drawn in as well as the overhangs 321,321' on both sides of the wire 32 bent against the piston 12 or the piston shoulder 121, where they are in the Insert the annular groove 123 provided on the circumference of the piston shoulder 121.
