Description

Flügel für EXzenterkolben von Preßluftmotoren Als Werkstoff für Flügel von Exzenterkolben von Preßluftmotoren wurde 'bisher Stahl oder Kunstharz verwendet. Die Lebensdauer dieser aus den genannten Werkstoffen hergestellten Flügel beträgt bei ausreichender Schmierung etwa 3 Wochen. Nach dieser Laufzeit müssen sowohl das Gehäuse als auch die Flügel ausgewechselt werden, da sich erhebliche Abnutzungserscheinungen an den gleitenden Flächen zeigen.Wings for eccentric pistons of compressed air motors As material for wings of eccentric pistons of compressed air engines, steel or synthetic resin was previously used. The service life of these blades made from the materials mentioned is with sufficient lubrication about 3 weeks. After this period, both the Housing as well as the wings have to be replaced, as there are considerable signs of wear and tear show on the sliding surfaces.

Im Gegensatz dazu konnte bei der erfindungsgemäßen Verwendung von Flügeln aus gesintertem Eisen mit einem etwa 30°/0 betragenden Porenvolumen, das mit geeigneten Schmierölen getränkt wird, festgestellt werden, daß nach 6 Wochen Laufzeit das Gehäuse noch eine spiegelnde Lauffläche hatte, die sogar die ursprünglichen Schleifmarken erkennen ließ. Es konnte ebenso wie die Flügel, die keine feststellbare Abnutzung zeigten, weiterverwendet werden. Diese Versuche wurden mit einem Drehkolbenmotor durchgeführt, wie er beispielsweise in der österreichischen Patentschrift 145 728 beschrieben ist.In contrast, when using Sintered iron blades with a pore volume of about 30 ° / 0, the soaked with suitable lubricating oils can be found that after 6 weeks The case still had a reflective running surface that was even the same as the original Showed grinding marks. It could just as well as the wings, which were not detectable Wear and tear showed to be re-used. These attempts were made with a rotary piston engine carried out, as for example in the Austrian patent specification 145 728 is described.

Die günstige Wirkung der erfindungsgemäßen Verwendung von mit Schmiermitteln getränktem, gesintertem Eisen muß auf die an sich bekannte, erhöhte Schmierwirkung dieses Werkstoffes zurückgeführt werden, die dadurch eintritt, daß das Schmiermittel aus dem porösen Innern durch die Fliehkraft den auf gleitende Reibung beanspruchten Flächen zugeführt wird.The beneficial effect of the use of lubricants according to the invention Impregnated, sintered iron must have the known, increased lubricating effect this material are returned, which occurs because the lubricant from the porous interior by the centrifugal force stressed on sliding friction Areas is supplied.
