Abstract
Description
Die Erfindung bezieht sich auf eine zugfeste Rohrverbindung nach dem Oberbegriff des Anspruchs 1.The The invention relates to a high tensile pipe joint after Preamble of claim 1.
Bei
einer zugfesten Rohrverbindung beispielsweise der in
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Rohrverbindung der bekannten Art so zu gestalten, dass ihre Montage auch unter Verzicht auf einen Montagehilfskörper ohne Beschädigung des Rohres vonstatten gehen kann.Of the present invention is based on the object, a pipe connection of the known type so that their assembly also under Waiver of an auxiliary assembly body without damaging the Tube can go.
Die Erfindung löst diese Aufgabe mit den Merkmalen des Anspruchs 1 und ist dementsprechend dadurch gekennzeichnet, dass die zahnartigen Vorsprünge des Sicherungsrings als im wesentlichen ringförmig umlaufende Rippen ausgebildet sind, und dass wenigstens eine dieser Rippen mit in Umfangsrichtung kurzen rippenartigen Nasen versehen ist, die gegenüber der Rippe radial erhöht sind.The Invention solves This object with the features of claim 1 and is accordingly characterized in that the tooth-like projections of the Circlip are designed as substantially annular circumferential ribs, and that at least one of these ribs is circumferentially short is provided rib-like lugs which are radially increased relative to the rib.
Bevorzugt ist die Anordnung in diesem Zusammenhang so getroffen, dass die Umfangserstreckung jeweils einer Nase etwa 2 bis 4% des Umfangs einer Rippe bzw. die Umfangserstreckung aller Nasen einer Rippe etwa 20 bis 40% des Umfangs der Rippe beträgt und dass – je nach Nenngröße des Rohres – die radiale Erhöhung der Nasen gegenüber der Rippe etwa 0,3 bis 1,5 mm beträgt.Prefers the arrangement in this context is such that the Peripheral extension of each nose about 2 to 4% of the circumference of a Rib or the circumferential extent of all noses of a rib about 20 to 40% of the circumference of the rib is and that - depending on Nominal size of the tube - the radial increase the noses opposite the Rib is about 0.3 to 1.5 mm.
Der wesentliche Kern der Erfindung besteht demnach darin, zwischen dem ursprünglich aufgeweitet in der Muffennut einliegenden und somit entspannten Sicherungsring und dem in den Sicherungsring einzuschiebenden Rohr nur einen möglichst geringen Kraftschluss zuzulassen, damit das Rohr bzw. seine Mantelfläche mechanisch kaum belastet wird und beschädigt werden kann. Der Kraftschluss soll gerade gewährleisten, dass bei am Rohr auftretenden Zugkräften der Sicherungsring mitgezogen werden kann, so dass er in der Lage ist, sich unter Durchmesserverjüngung enger an das Rohr anzulegen mit der Folge, dass nunmehr auch die Rippen insgesamt am Rohrmantel angreifen und dadurch den Kraftschluss im Sinne einer zugfesten Rohrverbindung erhöhen können.Of the The essential core of the invention is therefore between the originally expanded in the Muffennut einliegen and thus relaxed Circlip and the pipe to be inserted into the circlip only one possible allow low adhesion, so that the pipe or its lateral surface mechanically is hardly loaded and damaged can be. The adhesion is just to ensure that when occurring on the pipe tensile forces the circlip can be pulled so that he is able is under Diameter rejuvenation close to the pipe create with the result that now also the Overall, ribs on the pipe jacket attack and thereby the adhesion in the sense of a tensile pipe joint can increase.
Eine noch weitere Effektsteigerung des erfindungsgemäßen Prinzips kann entsprechend einer Ausgestaltung des Sicherungsringes dadurch erreicht werden, dass wenigstens eine der Rippen gegenüber wenigstens einer anderen Rippe selbst zumindest teilumfänglich radial erhöht ist. Auch hier soll die radiale Erhöhung der wenigstens einen Rippe gegenüber anderen Rippen etwa 0,3 bis 1,5 mm betragen.A even further effect enhancement of the principle according to the invention can be done accordingly an embodiment of the retaining ring can be achieved thereby that at least one of the ribs opposite at least one other Rib itself at least partially increased radially is. Again, the radial increase of the at least one rib across from other ribs about 0.3 to 1.5 mm.
Bei dieser Ausgestaltung gelangen anfangs nur die Nasen und also äußerst kleine Angriffsflächen mit dem Rohr in Kontakt, welches daher beim Einschieben in die Muffe mechanisch noch weniger belastet wird. Erst bei Zugbelastung greift/greifen später auch die erhöhte(n) Rippe(n) kraftschlüssig am Rohr an, wodurch der Kraftschluss sukzessive mit Zunahme der am Rohr angreifenden Auszugskräfte erhöht werden kann.at This embodiment initially reach only the noses and so extremely small Attack surfaces with the tube in contact, which therefore when inserted into the sleeve mechanically even less burdened. Only when pulling load attacks / grab later also the increased (s) Rib (s) non-positively on the tube, whereby the adhesion gradually with increase of Extending forces acting on the pipe are increased can.
Entsprechend einer weiteren Ausführungsform können die Rippen in Umfangsabständen Unterbrechungen bzw. Einschnitte aufweisen. Damit ist der Vorteil verbunden, dass die Kontaktflächen zwischen Rohr und Sicherungsring noch weiter verringert werden.Corresponding a further embodiment can the ribs at circumferential intervals Have interruptions or cuts. That's the advantage connected to the contact surfaces between pipe and circlip be further reduced.
Die Unterbrechungen bzw. Einschnitte können als axial verlaufende Nuten ausgebildet sein, die sich jeweils durch alle ringförmig umlaufenden Rippen hindurch erstrecken. Aufgrund dieser Ausbildung lässt sich der Sicherungsring besonders einfach im Spritzgießverfahren herstellen.The Interruptions or cuts can be considered axially extending Be formed grooves which are each circulating through all annular Ribs extend through. Because of this training can be the locking ring is particularly easy in the injection molding process produce.
