Description

Dichtring für die Abdichtung von Zylinderdeckeln für Brennkraftmaschinen Die Erfindung bezieht sich auf einen Dichtring für die Abdichtung von Zylinderdeckeln für Brennkraftmaschinen, welcher aus mindestens einer Lage Metallblech besteht.Sealing ring for sealing cylinder covers for internal combustion engines The invention relates to a sealing ring for sealing cylinder covers for internal combustion engines, which consists of at least one layer of sheet metal.

Außer massiven Kupferringen hat man zur Zylinderdeckelabdichtung von Brennkraftmaschinen auch schon für hohe Anpreßdrücke beidseitig mit Kupfer plattierte Eisenringe verwendet. Die elastische Verformbarkeit solcher Ringe ist aber wegen der geringen Dicke nicht ausreichend.In addition to massive copper rings, the cylinder cover is sealed by Internal combustion engines already plated with copper on both sides for high contact pressures Used iron rings. The elastic deformability of such rings is due to the small thickness is insufficient.

Bei Maschinen kleinerer Abmessungen sind auch schon sogenannte Weichstoffdichtungen benutzt worden, welche die erforderliche Elastizität und Plastizität durch gleichzeitige Verwendung verschiedener Werkstoffe, z. B. Kupfer und Asbest, zu erreichen versuchen. Für größere Abmessungen ist eine derartige Dichtung jedoch wegen der mangelnden Elastizität bei den hohen Dichtpressungen nicht geeignet.So-called soft material seals are already used in machines with smaller dimensions has been used, which has the required elasticity and plasticity by simultaneous Use of different materials, e.g. B. copper and asbestos, try to achieve. For larger dimensions, however, such a seal is due to the lack of Elasticity not suitable for the high sealing pressures.

Diese Mängel können bei einem Dichtring der eingangs erwähnten Art nach der Erfindung dadurch vermieden werden, daß der Dichtring im Querschnitt kreisabschnittförmig ausgebildet ist, wobei die Innen-und Außenkante in einer Ebene angeordnet sind. Durch eine derartige Maßnahme wird gegenüber einem ebenen mit Kupfer plattierten Eisenring eine wesentlich bessere elastische Verformbarkeit erreicht, so daß der Dichtring auch Bewegungen, welche aus im Betrieb auftretenden Kräften herrühren, infolge seines größeren Federweges besser ausgleichen kann. Die Beanspruchung des Dichtringes in radialer Richtung durch die Zünddrücke wird vom Werkstoff des Kernes, z. B. Stahl, aufgenommen, während die Oberfläche aus einem weichen Metall, z. B. Kupfer, die Rauhtiefen der Dichtflächen ausfüllt.These deficiencies can be found in a sealing ring of the type mentioned at the beginning can be avoided according to the invention in that the sealing ring is circular in cross section is formed, wherein the inner and outer edges are arranged in one plane. Such a measure is compared to a flat with copper-plated Iron ring achieved a much better elastic deformability, so that the Sealing ring also movements that result from forces occurring during operation, can better compensate due to its greater spring travel. The stress on the The sealing ring in the radial direction due to the ignition pressures is determined by the material of the core, z. B. steel, while the surface is made of a soft metal, e.g. B. Copper, which fills the surface roughness of the sealing surfaces.

Es ist zwar schon ein Zylinderdeckeldichtring mit gewölbtem Querschnitt bekannt. Die eine Hälfte des Querschnittes ist dabei jedoch eben, während die innere Hälfte in Form eines hochstehenden Ringwulstes ausgebildet ist. Da der Dichtring im eingespannten Zustand nicht völlig flachgedrückt werden soll, kann der Dichtring jedoch längs seiner ganzen Erstreckung nicht gleichmäßig angezogen werden, da durch die unter Umständen unterschiedliche Gewindereibung die aufgewendete Anpreßkraft kein sicheres Maß für die Verformung der Dichtung ist. Hingegen wird durch das Aufliegen des erfindungsgemäßen Dichtringes an beiden Rändern dieser erst flachgedrückt, ehe die eigentliche Anpreßkraft, die erheblich höher als erstere sein soll und genau berechnet werden kann, wirksam wird. Die Zeichnung stellt Ausführungsbeispiele der Erfindung dar.It is indeed a cylinder cover sealing ring with a curved cross-section known. However, one half of the cross-section is flat, while the inner half Half is designed in the form of an upstanding annular bead. Because the sealing ring should not be completely flattened when clamped, the sealing ring however, along its entire extent, cannot be tightened evenly, as through the possibly different thread friction the applied contact pressure is not a certain measure of deformation of the seal. On the other hand, by resting of the sealing ring according to the invention at both edges of this first pressed flat before the actual contact pressure, which should be considerably higher than the former and precisely can be calculated takes effect. The drawing represents exemplary embodiments of the Invention.

Der in F i g. 1 gezeigte Dichtring besteht aus einem Stahlkern 1, der beidseitig z. B. durch Walzen, Elektrolyse oder ein ähnliches Verfahren mit einer Kupferschicht 2 plattiert ist. Der Dichtring ist im Querschnitt kreisabschnittförmig ausgebildet, wobei die Innenkante 3 und die Außenkante 4 in einer Ebene angeordnet sind.The in F i g. 1 sealing ring shown consists of a steel core 1, the z. B. is plated with a copper layer 2 by rolling, electrolysis or a similar process. The sealing ring has a circular segment shape in cross section, the inner edge 3 and the outer edge 4 being arranged in one plane.

Für einen größeren Federweg können, wie F i g. 2 zeigt, zwei solcher Dichtringe spiegelbildlich zueinander angeordnet werden, die sich längs eines mittleren Durchmessers 5 berühren.For a larger spring deflection, as shown in FIG. 2 shows two such Sealing rings are arranged in mirror image to each other, extending along a middle Diameter 5 touch.
