Description
Stoßstellenausbildung für Kolbenringe mit winkelförmigem Querschnitt Die Erfindung bezieht sich auf die Stoßstellenausbildung von Kolbenringen, die durch einen Ansatz an der Lauffläche winkelförmigen Querschnitt erhalten, wobei der Ansatz auf der Seite niedrigeren Druckes angeordnet ist und die Kolbenringnut eine dem Laufflächenansatz des Ringes entsprechende Aussparung aufweist. Durch diesen sog. Entlastungsrand wird die an der Zylinderwand gleitende Lauffläche des Kolbenringes gegenüber der vom Gasdruck beaufschlagten Fläche vergrößert und dadurch der Anpreßdruck herabgesetzt. Die Winkelringe haben sich während des Betriebes durch geringeren Verschleiß ausgezeichnet, doch haben Leckgasmessungen ergeben, daß sie größere Leckgasverluste als Ringe rechteckigen Querschnittes haben. Als Ursache wurde im Lauf von Versuchen die durch den Entlastungsrand bedingte größere radiale Höhe des Durchströ.mquerschnittes am Ringstoß ermittelt.Joint formation for piston rings with an angular cross-section The invention relates to the joint formation of piston rings by received an approach on the tread angular cross-section, the approach is arranged on the side of lower pressure and the piston ring groove one of the Has tread approach of the ring corresponding recess. Through this so-called. The relief edge is the sliding surface of the piston ring on the cylinder wall increased compared to the area acted upon by the gas pressure and thereby the contact pressure degraded. The angle rings have decreased during operation Wear excellent, but leakage gas measurements have shown that they have greater leakage gas losses as rings of rectangular cross-section. The cause was found in the course of experiments the greater radial height of the flow cross section caused by the relief edge determined at the ring joint.
Um diesem Übelstand abzuhelfen, erhält der Kolbenring von winkelförmigem Querschnitt -an seinen Enden (in der Gegend der Stoßfuge) rechteckigen Querschnitt, und auch der winkelförmige Querschnitt.der Kolben:ringnut geht an einer Stelle in einen entsprechenden rechteckigen Querschnitt über. Es werden so die Vorteile des entlasteten Kolbenringes mit den geringeren Leckgasverlusten des gewöhnlichen Kolbenringes vereint. Die Zeichnung veranschaulicht den Ei-fi.ndungsgedanken beispielsweise an drei Ab- bildung en, von denen Abb. i den ges@-öhnlichen Kolbenring, Abb. a den seitherigen holbe-n,ring ,mit winkelförmigem (#ticrsclinitt und Abb.3 diesen entlasteten Kolbenring mit verbesserter Stol.lstell@e zeigt. Abb. i und zei-en die seitherigen Kolbenringe im Querschnitt, wobei die größere Hölie h des vom Gas durchströ fiten Querschnittes aii der StoPistelle durch den Entlastungsrand e des Ringes r bedingt ist.To remedy this inconvenience, the piston ring has an angular cross-section - at its ends (in the area of the butt joint) a rectangular cross-section, and also the angular cross-section. In this way, the advantages of the relieved piston ring are combined with the lower gas leakage losses of the conventional piston ring. The drawing illustrates the egg fi.ndungsgedanken for example, at three waste en education, in which: fig. I ges @ -öhnlichen the piston ring, Fig. A since then the Holbe-n, ring, #ticrsclinitt with winkelförmigem (and fig.3 these Relieved piston ring with improved Stol.lstell@e Fig. i and show the previous piston rings in cross-section, whereby the larger cavity h of the cross-section aii of the shock area through which the gas flows is due to the relief edge e of the ring r.
Abb.3 zeit radial von außen gesehen den erfindungsgemäß verbesserten Kolbenring, der an der Staßstellie zum einfachen Recht; ckring wird und dessen Ko.lbenringnut entsprechend ausgebildet ist.Fig.3 time, seen radially from the outside, the improved according to the invention Piston ring, the one at the Staßstellie to the simple right; ckring and its piston ring groove is designed accordingly.
