Description

Bekanntlich ist die Reibung bei reibenden Teilen abhängig von dem Reibungskoeffizienten und dem Reibungsdruck. Man kann nun in allen Fällen, wo der Reibungsdruck in einer Richtung erfolgt, denselben dadurch verringern, daß man dem Druck entgegenwirkend eine magnetische Kraft wirken läßt. Dies ist besonders dann zweckmäßig, wenn entweder sehr große Drücke vorhanden sind, die eine übermäßige Reibung ergeben, insbesondere die Schmiermittel nicht zur Auswirkung kommen lassen, weil die Reibungsgeschwindiigkeit zu gering ist, aber auch in Fällen, bei denen geringe Reibungsdrücke vorhanden sind, wo die übertragende Kraft, wie z. B. bei Meßinstrumenten und Waagen, gering, d. h. praktisch gleich Null sein muß.It is known that the friction in rubbing parts is dependent on the coefficient of friction and the frictional pressure. In all cases where the frictional pressure is in takes place in one direction, reduce the same by counteracting the pressure allows a magnetic force to act. This is particularly useful when either very high pressures are present, which result in excessive friction, especially the lubricants not having an impact let come because the friction speed is too low, but also in Cases where there are low frictional pressures, where the transmitted force, such as B. in measuring instruments and scales, low, d. H. practically zero got to.

Man kann entweder permanente Magnete oder Elektromagnete verwenden, evtl. auch einen der reibenden Teile zur Erhöhung der magnetischen Kraft magnetisch machen, wenn dadurch die Wirkung des anzubringenden Magnetes gesteigert wird. Unter Umständen ist es dabei vorteilhaft, daß die Magnete verstellbar sind, damit die Richtung bzw. Höhe der zur Wirkung kommenden Kraft regulierbar ist.You can either use permanent magnets or electromagnets, maybe also make one of the rubbing parts magnetic to increase the magnetic force, if this increases the effect of the magnet to be attached. In certain circumstances It is advantageous that the magnets are adjustable so that the direction or level of the force coming into effect is adjustable.

Die Anwendung des Verfahrens kann überall dort erfolgen, wo Reibungskräfte zu überwinden sind, gleichgültig, ob ruhende oder gleitende Reibung in Frage kommt, also beispielsweise bei Stützlagern, Zapfenlagern o. dgl., Geradführungen, wie Kolben, Kreuzköpfe u. dgl., Schneckengetriebe usw. Zweckmäßig ist es dabei, den einen Reibungstteil. beispielsweise den feststehenden, aus nichtmagnetisierbarem Material, wie Kupfer, Messing, Aluminium oder sonstigen Metallen oder Metallegierungen, oder auch aus nichtmetallenem, wie Hartholz, Hartgummi, Glas, Bakelite, Achat 0. dgl., auszuführen.The method can be used anywhere where frictional forces have to be overcome regardless of whether static or sliding friction comes into question, for example Appropriate for support bearings, journal bearings or the like, linear guides such as pistons, crossheads and the like, worm gears, etc. it is part of the friction. for example the fixed ones made from non-magnetizable ones Material such as copper, brass, aluminum or other metals or metal alloys, or also made of non-metallic, such as hardwood, hard rubber, glass, Bakelite, agate, etc.

Die Erfindung sei an Hand einiger Zeichnungen erläutert.The invention will be explained with the aid of a few drawings.

Fig. ι veranschaulicht ein durch die Welle b stark in Richtungd belastetes Lager a. Durch den permanenten oder elektrisch erregten Magneten c, dessen Kraft k dem Reibungsdruck im Lager entgegenwirkt, wird der Reibungsdruck und damit die Reibung vermindert. Das Lager kann zweckmäßigerweise aus unmagnetischem Metall, wie Messing oder Rotguß, bzw. aus Nichtmetall, wie Harthok, Bakelite, Achat o. dgl., bestehen, um ein evtl. magnetisches Anhaften zu vermeiden.Fig. Ι illustrates a bearing a heavily loaded by the shaft b in the direction d. The permanent or electrically excited magnet c, the force k of which counteracts the frictional pressure in the bearing, reduces the frictional pressure and thus the friction. The bearing can expediently be made of non-magnetic metal, such as brass or gunmetal, or of non-metal, such as hardwood, bakelite, agate or the like, in order to avoid possible magnetic adhesion.

Gemäß Fig. 2, in der ein Stützlager dargestellt ist, wird der Druck der Welle h auf das Stützlager i durch den über der Welle angeordneten Elektromagnet I, dessen Kraft m dem Reibungsdruck η entgegengesetzt wirkt, teilweise aufgehoben und somit der Reibungswiderstand vermindert; auch wird zweckmäßigerweise der Magnet verstellbar angeordnet, um die Magnetwirkung zu regulieren.According to FIG. 2, in which a support bearing is shown, the pressure of the shaft h on the support bearing i is partially canceled by the electromagnet I, which is arranged above the shaft and whose force m counteracts the frictional pressure η , and thus the frictional resistance is reduced; the magnet is also expediently arranged to be adjustable in order to regulate the magnetic effect.
