Description

Die Erfindung betrifft einen flüssigen Schmierstoff, der insbesondere zum Schmieren von Gleit- und Wälzlagern geeignet ist Von Schmierstoffen dieser Art wird verlangt, daß sie auch bei erhöhter Temperatur, etwa bis zu 3000C ihre Schmiereigenschaften nicht verlieren und insbesondere die Abnützung der geschmierten Teile verringern.The invention relates to a liquid lubricant which is particularly suitable for lubricating sliding and roller bearings. Lubricants of this type are required not to lose their lubricating properties even at elevated temperatures, for example up to 300 ° C., and in particular to reduce the wear and tear of the lubricated parts .

Aus der deutschen Patentschrift 12 52650 ist es bekannt, daß wasserstoff-modifizierte Fluorkohlenstoffäther infolge ihrer chemischen Indifferenz und ihrer Temperaturbeständigkeit als Schmiermittel geeignet sind. In der Vorveröffentlichung sind keine Abnützungswerte angegeben, da sich das dort beschriebene Verfahren speziell auf die Herstellung derartiger wasserstoff-modifizierter Fluorkohlenstoffpolyäther beziebtFrom the German patent specification 12 52650 it is known to be hydrogen-modified fluorocarbon ethers suitable as a lubricant due to their chemical indifference and their temperature resistance are. There are no wear and tear values in the pre-release indicated, since the method described there specifically relates to the production of such hydrogen-modified fluorocarbon polyether

Aus der DE-AS 19 28455 ist es bekannt, daß κ perforierte Äther- bzw. Polyäther-Guanaminverbindüngen ebenfalls als Schmiermittel geeignet sind. Ihre besondere Eigenschaft besteht darin, daß sie auch bei Temperaturen oberhalb von 260° C lange gebrauchsfähig bleiben. Obgleich in dieser Vorveröffentlichung *o Betspiele für die Verwendung der genannten Schmierstoffe bei verschiedenen Metall- und Stahllegierungen angegeben sind, sind auch dort keine Abnutzungswerte genannt Die in Tabelle III der Vorveröffentlichung genannten Gewichtsänderungen von Probescheiben «5 beziehen sich auf das Korrosionsverhalten in den genannten Schmierstoffen.From DE-AS 19 28455 it is known that κ perforated ether or polyether guanamine compounds are also suitable as lubricants. Their special property is that they remain usable for a long time even at temperatures above 260 ° C. Although this prior publication * o specifies the use of the lubricants mentioned in various metal and steel alloys, no wear values are given there either.

Aus der DE-AS 12 28 362 ist es bekannt, eine Dispersion von Molybdändisulfid in Hexafluorbenzol als Schmieröl bei Temperaturen von 500 bis 7000C zu w verwenden. Der Dispersion können gegebenenfalls noch Schutzkolloide zugesetzt werden. Ins Einzelne gehende Angaben über die Eigenschaften dieser Schmierstoffe sind in der Vorveröffentlichung nicht enthalten.From DE-AS 12 28 362 it is known, a dispersion of molybdenum disulfide as a lubricating oil in hexafluorobenzene at temperatures of 500 to 700 0 C to w use. If appropriate, protective colloids can also be added to the dispersion. The prior publication does not contain detailed information on the properties of these lubricants.

Schließlich ist auch aus der Vorveröffentlichung »Chemisches Zentralblatt« 1969, Nr. 6, 1892, bekannt, daß Fluorkohlenstoffpolyäther als Schmierstoffe geeignet sind. Auch diese Veröffentlichung bezieht sich im wesentlichen auf das Verfahren zum Herstellen solcher m> Stoffe.Finally, it is also known from the prior publication "Chemisches Zentralblatt" 1969, No. 6, 1892, that fluorocarbon polyethers are useful as lubricants. This publication also refers to the essential to the process of making such m> Fabrics.

Der Erfindung liegt die Aufgabe zugrunde, einen flüssigen Schmierstoff anzugeben, der insbesondere zum Schmieren von Gleit- und Wälzlagern geeignet ist und auch bei erhöhter Betriebstemperatur bis zu 300" C gute Hafteigenschaften an den zu schmierenden Teilen aufweist Die Lösung dieser Aufgabe ergibt sich aus dem kennzeichnenden Teil des Patentanspruches 1. Im Patentanspruch 2 ist ein weiteres vorteilhaftes Merkmal beschrieben und in Patentanspruch 3 ist eine bevorzugte Zusammensetzung des Schmierstoffes angegeben.The invention has for its object to be a specify liquid lubricant that is particularly suitable for lubricating plain and roller bearings and good adhesive properties on the parts to be lubricated even at higher operating temperatures of up to 300 "C The solution to this problem results from the characterizing part of claim 1. Im Claim 2 describes a further advantageous feature and claim 3 is a preferred one Composition of the lubricant specified.

Die angegebene Lösung der Aufgabe ist überraschend, da sie zu einem nicht vorherzusehenden technischen Erfolg geführt hat Vergleichende Verdrehversuche an Sollwerteinstellern für Temperaturregler bei 10 000 Verdrehungen und sonst gleichen Betriebsbedingungen haben gezeigt daß reine PerfluorpoJyätheröle sowie auch verseifte Perfluorpolyäth« einen Abnutzungsgrad von 34,2, und daß reines Molybdänsulfid einen Abnutzungsgrad von 292 zeigt Der erfindungsgemäß zusammengesetzte Schmierstoff zeigt jedoch nur einen Abnutzungsgrad von 18,0 oder weniger.The given solution to the problem is surprising, since it leads to an unforeseen one Technical success has led to comparative attempts to twist setpoint adjusters for temperature controllers with 10,000 rotations and otherwise the same operating conditions have shown that pure perfluoropolyether oils as well as saponified perfluoropolyethane produce one Wear rate of 34.2, and that pure molybdenum sulfide shows a degree of wear of 292. The lubricant composed according to the invention shows but only a wear factor of 18.0 or less.

Die Verwendung des angegebenen Schmierstoffes ist immer dann möglich, wenn es sich um den Einsatz flüssiger Schmierstoffe handelt nämlich beispielsweise für Wälz- und Gleitlager, als Schneidöl, zum Kaltformen aus Hydraulöl, als Motoren- und Getriebeöl für Kraftfahrzeuge, zur Hochtemperaturschmierung von Gleitbahnen, Gelenken und beweglichen Maschinenteilen aller Art Ferner als öl für die Umlauf- und Tauchschmierung von Getrieben.The specified lubricant can always be used when it comes to use Liquid lubricants are used, for example, for roller and plain bearings, as cutting oil, for cold forming from hydraulic oil, as engine and gear oil for motor vehicles, for high-temperature lubrication of Slideways, joints and moving machine parts of all kinds. Furthermore, as oil for the circulating and Splash lubrication of gears.

Ganz besonders wichtig aber ist die Verwendung des Schmierstoffes zur Schmierung von Sollwerteinstellern für Temperaturregler aller Art weil bei den meisten Reglern eine Betriebstemperatur von 300" C gefordert wird. Die bekannten Schmierstoffe weisen in diesem Temperaturbereich nur noch Notlaufeigenschaften auf und verursachen damit eine erhebliche Abnützung der geschmierten Teile. Da die Sollwerteinsteller von Temperaturreglern in das Gerät eingeschraubt werden, ergibt sich infolge der Abnützung eine unerwünschte Veränderung der Schaltpunkte des Reglers mit allen ihren Nachteilen.However, the use of the lubricant to lubricate setpoint adjusters is particularly important For temperature controllers of all kinds because most controllers require an operating temperature of 300 "C will. The known lubricants only have emergency running properties in this temperature range and thus cause considerable wear and tear on the lubricated parts. Since the setpoint adjuster of Temperature regulators are screwed into the device, results in an undesirable effect due to wear and tear Change of the switching points of the controller with all their disadvantages.

Bemerkenswert ist auch, daß durch das angegebene Schmiermittel die erwähnte Aufgabe nicht nur gelöst sondern darüber hinaus auch erreicht wird, daß die hervorragenden Notlaufeigenschaften des Molybdänsulfids in keiner Weise beeinträchtigt werden, wobei der Beschaffungspreis des angegebenen Schmierstoffes wesentlich geringer ist als der vergleichbarer Schmierstoffe. It is also noteworthy that the stated object is not only achieved by the specified lubricant it is also achieved that the excellent emergency running properties of molybdenum sulfide will not be affected in any way, the purchase price of the specified lubricant is significantly lower than that of comparable lubricants.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, das Molybdändisulfid in mikrofeinem Zustand zu verwenden. Hierdurch werden eine wesentlich höhere Dispersionsstabilität sowie noch bessere Schmiereigenschaften erzielt.In a further embodiment of the invention, it is proposed that the molybdenum disulfide in microfine State to use. This results in a significantly higher and even better dispersion stability Lubricating properties achieved.

Eine bevorzugte Zusammensetzung des Schmierstoffes besteht aus drei Gewichtsteilen Perfluorpolyätheröl und einem Gewichtiteil Molybdändisulfid.A preferred composition of the lubricant consists of three parts by weight of perfluoropolyether oil and one part by weight of molybdenum disulfide.
