Description

Verfahren zur Herstellung von Spannringdichtungen aus mittels Kunstharz zusammengebackenen Faserstoffen, insbesondere von Kolbenringen Dichtungsringe, insbesondere Kolbenringe für Kolbenpumpen zur Förderung von Luft bzw. Flüssigkeiten, sind zur Abdichtung von Wellen bzw. der Kolben an der Zylinderwand erforderlich und werden durch eigene Vorspannung oder durch irgendwelche Druckmittel gegen die Zylinderwand gepreßt.Process for the production of clamping ring seals by means of synthetic resin Caked fibrous materials, in particular from piston rings, sealing rings, in particular Piston rings for piston pumps for conveying air or liquids are for Sealing of shafts or pistons on the cylinder wall is required and will be by pretensioning yourself or by any pressure medium against the cylinder wall pressed.

Bei Flüssigkeiten mit schlechten Schmiereigenschaften ist die Abnutzung der Zylinderwände durch Metallkolbenringe groß, wodurch recht oft erhebliche Nacharbeiten erforderlich werden. Kolbenringe aus Metall haben auch, besonders wenn sie größere Abmessungen haben, ein erhebliches Gewicht und schlagen durch die bei größeren Hubzahlen und Geschwindigkeiten wirkenden Massenkräfte die Kolbennuten aus.In the case of fluids with poor lubricating properties, there is wear and tear the cylinder walls are large due to metal piston rings, which often means considerable reworking will be required. Metal piston rings also have, especially if they are larger Dimensions have a considerable weight and beat by with larger stroke rates and velocities, inertial forces affect the piston grooves.

Durch Verwendung von Kolbenringen aus Faserstoffen, welche durch Kunstharze zusammengehalten werden, lassen sich Reibung und Massenkräfte wesentlich herabsetzen.By using piston rings made of fibrous materials, which are replaced by synthetic resins are held together, friction and inertia forces can be significantly reduced.

Solche Kolbenringe haben besonders gute Laufeigenschaften, wenn der Faserstoff geschichtet ist und die Schichtrichtung senkrecht auf der Zylinderwand steht.Such piston rings have particularly good running properties when the Fiber is layered and the layer direction is perpendicular to the cylinder wall stands.

Dichtungsmaterial aus Phenol-Aldehyd-Kondensationsprodukten, das als Stopfbuchsenpackung oder zur Herstellung von Dichtungsringen für Kolbeneinlagen dienen soll, ist bekannterweisc so hergestellt worden, daß das mit Kunstharz imprägnierte Faserstoffmaterial, welches für den bestimmten Zweck zugeschnitten wird, während des Gebrauches als Dichtungsmittel durch den von der Stopfbuchse u. dgl. selbst erzeugten Druck und der an der betreffenden Stelle vorhandenen Wärme ausgebacken wird. Die Herstellung der Ringe erfolgt u. a. auch so, daß die Ringe aus Faserstoffplatten herausgeschnitten wurden; hierbei entsteht aber viel Verschnitt bzw. Abfall. Ferner besitzen solche Kolbenringe nicht die erwünschte Spannung. Gemäß der Erfindung werden nach folgendem Verfahren die verbesserten Kolbenringe mit großer Spannung hergestellt.Sealing material made from phenol-aldehyde condensation products, which is used as Stuffing box packing or for the production of sealing rings for piston liners is to serve, is known to have been made so that the impregnated with synthetic resin Fiber material, which is cut for the specific purpose, while of use as a sealant by the stuffing box and the like itself pressure generated and the heat present at the point in question will. The rings are manufactured, among other things. also so that the rings are made of fiber boards were cut out; but this creates a lot of scrap or waste. Further such piston rings do not have the desired tension. According to the invention the improved piston rings produced with great tension using the following process.

Die noch nicht vollkommen ausgebackenen Kunstharz-Faserstoff-Stäbe oder -Streifen werden in einen Zylinder oder um einen Dorn gelegt und dann in einem geeigneten Wärmeofen nachbehandelt, so daß das Kunstharz vollkommen erhärtet.The synthetic resin fiber rods that have not yet been completely baked out or strips are placed in a cylinder or around a mandrel and then in one post-treated in a suitable heating furnace, so that the synthetic resin hardens completely.

Bei Verwendung von geschichteten Faserstoffen, z. B. Gewebebahnen, werden Platten gepreßt, deren Dicke gleich der Breite der Kolbenringe ist. Diese Platten bleiben nur so lange in der Presse, als zur Überführung des Kunstharzes in eine feste Form erforderlich ist; dann werden aus der Platte Streifen oder Stäbe geschnitten, deren Breite gleich der radialen Stärke der herzustellenden Kolbenringe ist. Diese Stäbe sind noch weitgehend biegsam und werden nun um einen. zylindrischen Körper gebogen, dessen Durchmesser abhängig ist von dem Durchmesser des .Zylinders, in dem die Ringe laufen, und der Vorspannung, welche die Ringe erhalten sollen. Um die Ringe auf dem.zylindrischen Körper festzuhalten, wird ein Band oder Draht außen herumgelegt.When using layered fibers, e.g. B. fabric panels, plates are pressed, the thickness of which is equal to the width of the piston rings. These Plates only stay in the press as long as they are used to transfer the synthetic resin in a solid form is required; then strips or rods are made from the plate cut, the width of which is equal to the radial thickness of the one to be produced Piston rings is. These rods are still largely flexible and are now around one. cylindrical Curved body, the diameter of which depends on the diameter of the cylinder, in which the rings run, and the pretension that the rings should receive. A band or wire is used to hold the rings on the cylindrical body lying around outside.

Denselben Zweck erreicht man auch, wenn man den Stab in eine zylindrische Außenform hineinbiegt, wo@ er durch die eigene Spannung festgehalten wird.The same purpose can also be achieved by turning the rod into a cylindrical one The outer shape bends in, where @ it is held in place by its own tension.

Hierauf werden die Ringe mit ihren Formkörpern einer Wärmebehandlung. im Trockenschrank unterzogen. Nach der Wärmebehandlung werden die Ringe vom Formkörper entfernt, wobei sie ihre Ringgestalt behalten.The rings with their shaped bodies are then subjected to a heat treatment. subjected in the drying cabinet. After the heat treatment, the rings are removed from the molded body removed, keeping their ring shape.

Diese Ringe können wie Metallringe, welche eine Stoßfuge haben, auf den Kolben aufgebracht und mit diesem in den Zylinder eingesetzt werden.These rings can be like metal rings that have a butt joint applied to the piston and inserted into the cylinder with this.

Die Spannringdichtungen bzw. Kolbe können überall da verwendet werden, wo die Temperatur Werte nicht übersteigt, bei welchen der Werkstoff in seinen Eigenschaften beeinträchtigt wird.The clamping ring seals or pistons can be used anywhere where the temperature does not exceed values at which the material's properties is affected.
