Description
Bei Großgasmaschinen treten häufig Verluste an dem öl, welches zur Schmierung der Triebwerksteile (Kurbelzapfen, Kreuzköpfe u. dgl.) benutzt wird, dadurch auf, daß dasselbe auf die S Kolbenstange geschleudert und auf dieser beim Rückgang mit in das Zylinderinnere geführt wird. So unscheinbar diese Verluste im ersten Augenblick sein mögen, sind sie doch bei der stetigen Wiederholung sehr fühlbar, was bei den großenIn large gas engines, there are often losses of the oil that is used to lubricate the engine parts (Crank pin, crossheads and the like.) Is used, in that the same on the S The piston rod is thrown and is guided into the interior of the cylinder on this when it retreats. As inconspicuous as these losses may be at first, they are constant with the one Repetition very palpable, which is the case with the big ones
to Abmessungen der Kolbenstangen solcher Maschinen leicht erklärlich wird. Da es sich hierbei außerdem stes um wertvolle öle handelt, muß darnach gestrebt werden, diesen Übelstand zu vermeiden, und man hat es bereits durch Schutzschirme, Manschetten und Abstreifringe mit rechteckgiem Querschnitt versucht, ohne jedoch eine ausreichende Wirkung zu erzielen.to the dimensions of the piston rods of such machines is easy to explain. Since this is In addition, if it is a matter of valuable oils, efforts must be made to remedy this evil to avoid, and you already have it through protective screens, sleeves and wiper rings tried with a rectangular cross-section, but without achieving a sufficient effect.
Der Gegenstand der vorliegenden ErfindungThe subject of the present invention
ist ein Mittel, diese Verluste zu vermeiden. Es geschieht durch Einbau einer an und für sich bekannten Vorstopfbüchse, die die Aufgabe hat, das öl von der Stange zu entfernen vor die eigentliche im Zylinderdeckel abdichtende Stopfbüchse. Erreicht wird der Zweck durch eigenartige Ausbildung der die Stange umschließenden Stopfbüchsenringe mit schräg gegen die Einführungsrichtung des Öles gerichteten Kanten, an denen sich das öl abstreift und in besonderen ringförmigen Taschen sammelt, ausis a means of avoiding these losses. It is done by incorporating one in and of itself known pre-stuffing box, which has the task of removing the oil from the rod in front of the actual stuffing box sealing in the cylinder cover. The purpose is achieved through peculiar Formation of the stuffing box rings surrounding the rod with edges directed obliquely against the direction of introduction of the oil, where the oil is wiped off and collected in special ring-shaped pockets

In der Abbildung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es ist a die Kolbenstange, die durch den Zylinderdeckel δ hindurchgeführt ist und in diesem gegen das Zylinderinnere c durch die Stopfbüchse d abgedichtet wird. Vor dieser Stopfbüchse gewöhnlicher Bauart ist die Vorstopfbüchse eingebaut, die aus einem ringförmigen Gehäuse e und darin angeordneten Ringen f1 bis f 4 besteht. Die Ringe sind dreiteilig und werden durch außen aufgesetzte Federn g1 bis g4 mit leichtem Druck gegen die Kolbenstange gehalten.In the figure, an embodiment of the invention is shown. It is a the piston rod that is passed through the cylinder cover δ and is sealed in this against the cylinder interior c by the stuffing box d. In front of this stuffing box of conventional design, the pre-stuffing box is installed, which consists of an annular housing e and rings f 1 to f 4 arranged therein. The rings are in three parts and are held against the piston rod with light pressure by springs g 1 to g 4 placed on the outside.
Die Ringe sind mit schrägliegenden Abstreifkanten versehen, die in einem Winkel von etwa 60 ° gegen die Kolbenstangenoberfläche gerichtet sind und etwa auf dieser befindliches öl abstreifen. Zwischen den Ringen bzw. den Abstreifkanten sind ringförmige Taschen h1 bis h& gebildet, in denen sich das öl sammelt und aus denen es durch geeignete Bohrungen und Leitungen abgeführt werden kann. Die Abstreifringe sind in Gruppen von je zwei zusammengefaßt, zwischen denen ein trennender Ring i eingeschoben ist, der zur Bildung größerer Sammelräume dient.The rings are provided with sloping scraper edges, which are directed at an angle of about 60 ° against the piston rod surface and scrape off any oil located on this. Between the rings or the scraper edges, annular pockets h 1 to h & are formed, in which the oil collects and from which it can be drained through suitable bores and lines. The scraper rings are combined in groups of two, between which a separating ring i is inserted, which serves to form larger collecting spaces.
