Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Man hat bisher für Pumpen und Dampfmaschinen Kolbenringe fast nur aus Metall hergestellt. Es fand hierbei eine grofse Abnutzung der Cylinderwandungen statt, wenn nicht gleichzeitig für eine angemessene Schmierung gesorgt wurde. In den letzten Jahren hat sich nun der Graphit als ein vorzügliches Schmiermittel für Kolbenringe bewährt, so dafs der Gedanke nahe lag, die Kolbenringe aus Graphit herzustellen. In Anbetracht, dessen, dafs dem Kolbenring eine gewisse Elasticität innewohnen mufs, damit er sich an den Cylinderwandungen überall gleichmäfsig anlegt, war es nun zunächst nothwendig, den Graphit mit einem elastischen Körper in Verbindung zu bringen, und es zeigte sich bei Versuchen, dafs hierfür Hartgummi aufserordentlich geeignet sei. Wenn die Thatsache, dafs sich Graphit mit Hartgummi verbindet, auch schon allgemein bekannt ist, so ist doch noch von keiner Seite eine derartige Verbindung gebracht worden mit dem ausgesprochenen Zweck, den Graphit als Schmiermittel darin dienen zu lassen. Je nachdem man der Rohgummimasse 20 bis 50 pCt. Graphit in fein gemahlenem Zustand zusetzt, erhält man nach erfolgter Vulkanisation einen Hartgummi, der mehr oder weniger Graphit beim Aufstreichen auf eine Fläche abgiebt, und man hat es hierdurch in der Hand, einen mehr oder minder stark schmierenden Kolbenring herzustellen. Die äufsere Form der Graphit-Hartgummi-Kolbenringe wird man von der allgemein üblichen Form der Metallkolbenringe (Fig. 1 und 2) nicht abweichen lassen; es sei hier nur noch bemerkt, dafs die Abnutzung eine sehr geringe ist, indem bekanntlich schon sehr wenig Graphit zu einer wirksamen Schmierung ausreicht.Up to now, piston rings for pumps and steam engines have been made almost entirely of metal manufactured. There was great wear and tear on the cylinder walls, if Adequate lubrication has not been provided at the same time. In recent years graphite has now proven to be an excellent lubricant for piston rings, see above that the idea was obvious to make the piston rings out of graphite. In view of what, that the piston ring must have a certain elasticity so that it can be attached to the cylinder walls Applied uniformly everywhere, it was now necessary first of all to add the graphite with an elastic body, and it has been shown in attempts to that hard rubber is extremely suitable for this. If the fact is that Graphite connects with hard rubber, which is already well known, is still from neither side has been so associated with the stated purpose Let graphite serve as a lubricant in it. Depending on the raw rubber mass 20 to 50 pct. Adding graphite in a finely ground state is obtained after Vulcanization a hard rubber that contains more or less graphite when brushed onto a Surface gives off, and you have it in your hand, one more or less strong to produce lubricating piston ring. The outer shape of the graphite hard rubber piston rings one becomes of the generally usual shape of the metal piston rings (Fig. 1 and 2) don't let it deviate; it should only be noted here that the wear and tear is very slight is because, as is well known, very little graphite is sufficient for effective lubrication.
