Description
Im Patent 898343 sind Hochdruckschmierstoffe geschützt, die durch Vermischen von Chlorparaffinen mit fettsauren Salzen erhalten werden. Es wurde gefunden, daß in diesen Mischungen die fettsauren Salze ganz oder teilweise durch eine Reihe anorganischer Metalloxyde oder -salze ersetzt werden können, wobei ebenfalls Hochdruckschmierstoffe von gleichem bzw. ähnlich hohem Schmiervermögen bei hochdruckbelasteten Lagern erhalten werden. Als wirksame anorganische Metalloxyde oder -salze erwiesen sich: Calciumcarbonat, Calciumsulfat, Calciumphosphat, Zinkoxyd; Zinkcarbonat, Talkum oder Lithopone. Als besonders wirksam wurden Calciumcarbonat, Calciumsulfat und Zinkoxyd gefunden. Da es sich bei diesen Verbindungen um weit verbreitete Stoffe handelt, die leichter zugänglich sind als fettsaure Salze, bedeutet die Erkenntnis ihrer Verwendungsmöglichkeit zur Herstellung von Hochdruckschmierstoffen in Mischung mit Chlorparaffinen einen weiteren technischen Fortschritt.In the patent 898343 high pressure lubricants are protected, which are obtained by mixing chlorinated paraffins with fatty acid salts. It has been found that the fatty acid salts in these mixtures can be wholly or partly replaced by a number of inorganic metal oxides or salts, high-pressure lubricants of the same or similarly high lubricity being obtained in bearings subjected to high pressure. The following have proven to be effective inorganic metal oxides or salts: calcium carbonate, calcium sulfate, calcium phosphate, zinc oxide; Zinc carbonate, talc or lithopone. Calcium carbonate, calcium sulfate and zinc oxide have been found to be particularly effective. Since these compounds are widely used substances that are more easily accessible than fatty acid salts, the knowledge that they can be used for the production of high-pressure lubricants mixed with chlorinated paraffins represents a further technical advance.
Es ist zwar bekannt, konsistente Schmierfette auf Schmieröl/Seifenbasis
mit Zusätzen von Calciümcarbonat und Calciumsulfat zu versehen, um ihre Druckbeständigkeit
zu steigern. Die durch diese Maßnahme sich ergebenden Wirkungen sind indessen sowohl
ihrer Art als auch ihrer Größenordnung nach wesentlich verschieden von der Schmierwirkung,
die mit den erfindungsgemäßen Hochdruckschmierstoffen erzielt wird. Vergleichende
Messungen an der Almen-Wieland-Ölprüfmaschine zeigen, daß sich die Druckbeständigkeit
eines gewöhnlichen Staufferfettes durch Zusatz von Calciumcarbonat oder Calciumsulfat
zwar steigern läßt; die mit solchen Zusätzen versehenen Fette verhindern beim hochdruckbelasteten
Lager das durch Lagerfraß bekannte Verschweißen von Lagerbolzen und Lagerschale,
sie verhindern aber nicht die Bildung tiefer und scharfer Schleifrillen an den Gleitflächen
sowie einen dementsprechenden Verschleiß des Lagers, und sie vermögen es nicht,
die Lagerreibung im Gebiete hoher Lagerdrucke in nennenswertem Umfange herabzusetzen.
Demgegenüber findet bei Lagern, die mit den erfindungsgemäßen Hochdruckschmierstoffen
geschmiert werden, selbst bei höchsten Lagerdrucken kein nennenswerter Lagerverschleiß
statt; Lagerbolzen und Lagerschalen bleiben an den Gleitflächen völlig glatt und
blank. Sie erhalten sich wie poliert. Ferner sind die meßbaren Reibungswerte selbst
bei extremer.. Steigerung des Lagerdruckes überraschend niedrig. Die nachstehend
wiedergegebene Tabelle gibt Messungen an der Almen-Wieland-Ölprüfmaschine wieder.
Die Messungen wurden entweder bis zum Verschweißen von Lagerbolzen und Lagerschale
oder bis zum höchst erreichbaren Lagerdruck, der sich bei der benutzten Prüfmaschine
erzielen ließ, fortgeführt. Zur Messung gelangten folgende Schmierstoffe: A reines
Chlorparaffin, B Chlorparaffin in Mischung mit etwa 13 °/a Calciumcarbonat, C Chlorparaffin
in Mischung mit etwa 13 °/o Calciumsulfat, D Staufferfett, E Staufferfett mit Zusatz
von 13 % Calciumcarbonat, F Staufferfett mit Zusatz von 13 °/a Calciumsulfat.
