Description

Die Erfindung besteht in einer Stopfbüchsenpackung in Form von kegeligen, nachgiebigen Manschetten, welche durch den Druck des Druckmittels von selbst gegen die KoI-benstange angepreßt werden. Gemäß der Erfindung besteht die Manschette aus einem elastischen Streifen, der an der einen Längskante quer zu seiner Längsrichtung mit Schlitzeinschnitten versehen ist, welche ίο zweckmäßig schräg geneigt zu seiner Oberfläche vorgesehen sind, wodurch die so gebildeten Lappen beim Einbringen des Streifens in die Stopfbüchse sich konisch überlappen und an die abgedichtete Welle oder Stange dicht anschließen.The invention consists in a gland packing in the form of conical, resilient Cuffs, which by the pressure of the pressure medium against the piston rod by themselves be pressed. According to the invention, the cuff consists of an elastic strip which is attached to one longitudinal edge is provided transversely to its longitudinal direction with slot incisions, which ίο are expediently provided obliquely to its surface, whereby the so formed When inserting the strip into the stuffing box, lobes overlap conically and attach to the sealed shaft or Connect the rod tightly.

In der Zeichnung ist ein Ausführungsbeispiel einer derartigen Packung veranschaulicht. Abb. ι zeigt einen Achsenschnitt durch die Stopfbüchse. Abb. 2 eine Draufsicht der ao abgewickelten Manschette.An exemplary embodiment of such a pack is illustrated in the drawing. Fig. Ι shows an axial section through the stuffing box. Fig. 2 is a plan view of the ao unwound cuff.

Wie die Zeichnung erkennen läßt, befindet sich die Packung innerhalb der Stopfbüchse 1 und dient zur Abdichtung der Kolbenstange 2. Die äußere Anpressung erfolgt in üblicher Weise durch die Brille 3. Die Abdichtung erfolgt durch die beiden entgegengesetzt zueinander gerichteten Manschetten 4, 5 von konischer Form aus weichem, nachgiebigem Stoff, wie z. B. Leder, Gummi o. dgl. Die äußeren Schäfte dieser Manschetten liegen zwischen je einer konischen Brille 6 und einem äußeren konischen Ring 7, zwischen denen sie fest eingepreßt sind. Die beiden Ringe 7, 7 werden zusammengehalten durch in je einen Hals 8 eingreifenden zylindrischen Haltering 9, welcher zweckmäßig aus zwei oder mehreren in der Achsenrichtung geschnittenen Teilen besteht, die von außen in den Hals 8 eingelegt sind. Auf diese Weise werden die beiden Manschetten mit ihren Schäften nicht nur festgeklemmt, sondern auch in Entfernung zueinander gehalten.As the drawing shows, the packing is inside the stuffing box 1 and serves to seal the piston rod 2. The external pressure takes place in the usual way Way through the glasses 3. The seal is made by the two opposite to each other directed cuffs 4, 5 of conical shape made of soft, resilient material, such as. B. leather, rubber o. The like. The outer shafts of these cuffs are between each a conical pair of glasses 6 and an outer conical ring 7 between which they are firmly pressed. The two Rings 7, 7 are held together by each engaging in a neck 8 cylindrical Retaining ring 9, which is conveniently cut from two or more in the axial direction There are parts that are inserted into the neck 8 from the outside. This way the two cuffs will be with their Shafts not only clamped, but also kept at a distance from each other.

Die Manschetten werden gebildet aus Lederstreifen (vgl. Abb. 2), welche quer zu ihrer Längsrichtung mit schrägen, zur Oberfläche gerichteten Schärf schnitten 13, 13 eingeschnitten sind. Die so gebildeten Lappen überlappen sich beim Einbringen des Streifens in die Stopfbüchse in konischer Form und legen sich dicht an die abgedichtete Welle oder Stange an.The cuffs are made of leather strips (see Fig. 2), which are perpendicular to their In the longitudinal direction with inclined, sharpening directed towards the surface, 13, 13 incised are. The lobes formed in this way overlap when the strip is inserted into the Stuffing box in a conical shape and lie tightly against the sealed shaft or rod at.

Zum Festpressen des abdichtenden Teiles der Manschette dienen zwei an ihrer Innenseite konisch geformte Ringe 10, 10, welche durch Federn 11, 11 gegen die Manschette gepreßt werden, wobei sich diese Federn gegen einen ringförmigen inneren Flansch 12 des ringförmigen Halters 9 stützen. Diese Ringe 10 pressen unter dem Druck der Federn 11 die Enden der Manschette fest gegen die Kolbenstange. Two on the inside serve to press the sealing part of the cuff in place conically shaped rings 10, 10 which are pressed by springs 11, 11 against the cuff be, these springs against an annular inner flange 12 of the support ring-shaped holder 9. These rings 10 press under the pressure of the springs 11 Ends of the sleeve firmly against the piston rod.

Die Anordnung hat den Vorteil, daß auch stark eingelaufene Kolbenstangen, mögen dieselben mit Längsriefen versehen oder unrund geworden sein, wirksam abgedichtet werden.The arrangement has the advantage that even heavily worn-in piston rods like the same be provided with longitudinal grooves or have become out of round, be effectively sealed.

Die Abnutzung der Manschetten ist nach den gemachten Erfahrungen verhältnismäßig gering und eine Nachstellung der Packung während sehr langer, ununterbrochener Betriebsdauer so gut wie nicht erforderlich.Experience has shown that the wear on the cuffs is proportionate low and readjustment of the packing during a very long, uninterrupted period of operation as good as not required.
