Description
Hydraulische Arbeitszylinder Im allgemeinen werden hydraulische Arbeitszylinder in der Weise abgedichtet, daß anstelle der früher gebräuchlichen Weichkupferringe, Papierdichtungen, Dichtungsmassen usw. jetzt mehr und mehr O-Ringe aus ölbeständigen Gummiqualitäten verwendet werden, die sich allgemein durchgesetzt haben. Diese O-Ringe werden in Nuten untergebracht, die entweder in den Arbeitszylinder eingearbeitet oder in dem Deckel ausgespart sind, der auf den Arbeitszylinder aufgesehraubt oder an diesen angeflansche ist. Hydraulic working cylinders In general, hydraulic working cylinders are used sealed in such a way that instead of the previously used soft copper rings, Paper gaskets, sealants, etc. now have more and more O-rings made of oil-resistant Rubber grades are used, which have become generally accepted. These o-rings are housed in grooves that are either incorporated into the working cylinder or are recessed in the cover, which is screwed onto the working cylinder or is flanged to this.
Schwierigkeiten ergeben sich bei dem Einbau insofern, als das genaue Einhalten der Maße für den Deckel beim Drehen nicht immer ganz einfach ist, zumal dann, wenn der Deckel einem hohen Druck ausgesetzt ist. Wird der Deckel in üblicher Weise mittels Schrauben befestigt, besteht die Gefahr, daß durch die Elastizität der Schraubenbolzen der Deckel sich abhebt, so daß dann der 0-Ring in den entstehenden Spalt gedrückt und beschädigt wird.Difficulties arise in the installation insofar as the exact Keeping the dimensions for the lid when turning is not always easy, especially since when the lid is exposed to high pressure. Will the lid in more usual Way fastened by means of screws, there is a risk that due to the elasticity the screw bolt of the cover lifts off, so that the O-ring is then in the emerging Gap is pressed and damaged.
Diese Paßarbeit für den Deckel-unabhängig davon, ob dieser nun aufgeschraubt oder angeflanscht wird-ist stets eine teuere Fertigung und somit nicht immer tragbar.This fitting work for the lid - regardless of whether it is now screwed on or is flanged-is always an expensive production and therefore not always affordable.
Die neuerungsgemäße Lösung, die aufgrund der vorgenannten Nachteile vorgeschlagen wird, besteht darin, daß als Dichtung für hydraulische Arbeitszylinder, insbesondere als Abschluß, ein mit O-Ringen versehener kolbenartiger Deckel eingesetzt ist, dessen Außendurchmesser dem Innendurchmesser des Arbeitsylinders entspricht. Diese kolbenartigen Deckel können somit als Abschluß-oder Führungsdeckel dienen.The innovation according to the solution, due to the aforementioned disadvantages is proposed, is that as a seal for hydraulic working cylinder, in particular as a conclusion, a piston-like cover provided with O-rings is used whose outside diameter corresponds to the inside diameter of the working cylinder. These piston-like covers can thus serve as a closure or guide cover.
Zweckmäßigerweise erfolgt die Sicherung hierfür mittels eines Sicherungsringes, der sich in einer in den Arbeitszylinder eingelassenen Nut zum Zylinderinnern hin führt. Bei geringen Arbeitsdrücken kann diese Art der Sicherung des als Kolben ausgebildeten Abschlußdeckels nach außen auch verwendet werden.Appropriately, this is done by means of a locking ring, which extends towards the inside of the cylinder in a groove embedded in the working cylinder leads. At low working pressures can do this type of backup of the end cap, which is designed as a piston, can also be used to the outside.
Eine weitere Form der Sicherung ist noch in der Weise gegeben, daß man in den Arbeitszylinder einen Rücksprung einarbeitet, so daß dann der kolbenartige Deckel sich gegen die dadurch gebildete Schulter abstützt. Nehmen diese Arbeitsdrücke nun höhere Werte an, so erfolgt die Sicherung des kolbenartigen Deckels in der Art, daß ein aus Segmenten gebildeter Ring, der in einer in den Arbeitszylinder eingearbeiteten Nut den kolbenartigen Deckel nach außen sichert und von einer mit dem kolbenartigen Deckel verbundenen Scheibe gehalten wird.Another form of security is given in such a way that a recess is worked into the working cylinder, so that the piston-like Lid is supported against the shoulder formed thereby. Take these working pressures now higher values, the piston-like cover is secured in the manner that a ring formed from segments, which is incorporated into the working cylinder Groove secures the piston-like cover to the outside and from one with the piston-like Lid connected disc is held.
Ein Ausführungsbeispiel der Neuerung ist in den Abbildungen schematisch dargestellt, wobei Abb. 1 eineh hydraulischen Arbeitszylinder im Längsschnitt und Abb. 2 den Arbeitszylinder als Ansicht in Richtung"A"der Abb. 1 wiedergeben.An exemplary embodiment of the innovation is shown schematically in the figures shown, Fig. 1 einh hydraulic working cylinder in longitudinal section and Fig. 2 show the working cylinder as a view in direction "A" of Fig. 1.
Bin Arbeitszylinder 1, der als Führung für einen Kolben 8 dient, ist mittels O-Ringen 9, die in einem kolbenartigen Deckel 2,3 untergebracht sind, nach beiden Seiten hin abgedichtet, wobei der kolbenartige Deckel 2 als Abschlußdeckel dient und der kolbenartige Deckel 3 als Filhrungsdeckel für die Kolbenstange.Am working cylinder 1, which serves as a guide for a piston 8, is by means of O-rings 9, which are housed in a piston-like cover 2.3, after sealed on both sides, the piston-like cover 2 as a cover serves and the piston-like cover 3 as a guide cover for the piston rod.
Sicherungsringe 4, 5, 6 halten die kolbenartigen Deckel 2,3 im Arbeitszylinder 1. Besteht ein Sicherungsring, wie z. B. der Sicherungsring 6, aus einzelnen Segmenten, so wird dieser Sicherung ! : rindmittels einer Scheibe 7 in seiner Lage gehalten, wobei die Scheibe 7 mit dem kolbenartigen Deckel 2 verschraubt ist.Circlips 4, 5, 6 hold the piston-like cover 2, 3 in the working cylinder 1. Is there a locking ring, such as B. the locking ring 6, made of individual segments, so will this fuse! : beef held in place by means of a disc 7, the disc 7 being screwed to the piston-like cover 2.
