'Schmierfett für tiefe Temperaturen'Grease for low temperatures
Anwendungsgebiet der Erfindung · Field of application of the invention
Me -Erfindung betrifft Sciimierfette für die Schmierung von nicht beheizten technischen Außenanlagen im Winter, ist aber auch zur Anwendung an Anlagen in der Kältetechnik geeignet, die überwie-. gend Temperaturen unter dem Gefrierpunkt ausgesetzt sind.Me invention relates Sciimierfette for the lubrication of non-heated technical outdoor facilities in winter, but is also suitable for use in systems in refrigeration, the predominant. low temperatures are exposed.
Charakterisierung der bekannten technischen Lösung Die Schmierung fettgeschmierter Schmierstellen an nicht beheizten technischen Anlagen wie beispielsweise Sicherungsanlagen im Eisenbahnwesen, Krananlagen und ähnlichen Einrichtungen bereitet bis zu wenigen Graden unter dem Gefrierpunkt allgemein keine besonderen Schwierigkeiten. Häufig treten jedoch Schwierigkeiten auf, wenn die Temperaturen längere Zeit bei -10 0C und tiefer liegen. Normale Schmierfette werden sehr fest und insbesondere an Lagerstellen, die nur zeitweilig arbeiten, tritt ein hoher Anlaufwiderstand im Lager auf, der bei elektrischen Antrieben sehr häufig zur Überlastung des Antriebsmotors und damit zu eir.ei Betriebsstörung führt. Für derartige Anwendungsfälle werden allgemein Tieftemperaturfette zur Anwendung empfohlen, die unter ^Verwendung von Kältemaschinenöleη hergestellt werden. Kältemaschinenöle werden nach speziellen Verfahren durch aufwendige Raffinationsverfahren aus ausgewählten Erdölen oder auch auf synthetischer Basis hergestellt, sind teuer und stehen nur in beschränktem Umfang(zur Verfügung, so daß die Anwendung von Tieftemperaturfetten auf breiter Basis im Winter nicht gewährleistet Characterization of the known technical solution The lubrication of grease-lubricated lubrication points on non-heated technical equipment such as safety systems in the railway industry, crane systems and similar facilities prepares up to a few degrees below freezing generally no particular difficulties. Often, however, difficulties arise when temperatures extended period of time at -10 0 C and lower. Normal greases are very firm and especially at bearings that work only temporarily, a high starting resistance occurs in the camp, which often leads to overloading of the drive motor and thus eir.ei malfunction in electric drives. For such applications, low temperature greases are generally recommended for use which are produced using refrigeration oils. Refrigeration oils are produced by special processes by complex refining of selected petroleum or synthetic base, are expensive and are available only to a limited extent ( so that the application of low temperature greases on a broad base in winter is not guaranteed
Ziel der Erfindung ist es, die Schmierung nicht beheizter fettgeschmierter Schmierstellen bei tiefen Temperaturen unter dem !Gefrierpunkt störungsfrei zu sichern.The aim of the invention is to ensure the lubrication of non-heated grease-lubricated lubrication points at low temperatures below the freezing point trouble-free.
Darlegung des Wesens der Erfindung Explanation of the essence of the invention
Durch zu hohe Konsistenz der Schmierfette an Schmierstellen nicht beheizter Außenanlagen·kommt es bei tiefen Temperaturen im Winter sehr häufig zu Betriebsstörungen, die unplanmäßige 35Ausfälle der Anlagen verursachen, zusätzlichen Wartungsaufwand erfordern und Betriebsgefährdungen hervorrufen«.Excessive consistency of the greases at lubrication points of unheated outdoor facilities · During winter, low temperatures often lead to malfunctions that cause unscheduled plant failures, require additional maintenance and cause operational hazards «.
Es wurde gefunden» daß Schmierfette auf Seifenbasis, die neben Mineralöl Glykole, gegebenenfalls etwas Wasser, Korrosionsinhibitoren und EP-Zusätze enthalten, bis zu sehr tiefen Tempera-40turen unter dem Gefrierpunkt, eine niedrige Konsistenz aufweisen und somit sehr gut zur Schmierung von nicht beheizten fettgeschmierten Schmierstellen an technischen Außenanlagen, wie Sicherungsanlagen im Eisenbahnwesen, Kränen und ähnlichen Einrichtungen geeignet sind.It has been found that soap-based greases which, in addition to mineral oil, contain glycols, optionally some water, corrosion inhibitors and EP additives, have a low consistency up to very low temperatures below freezing and thus very well for the lubrication of unheated grease-lubricated greases Lubrication points on technical outdoor facilities, such as safety systems in the railway industry, cranes and similar facilities are suitable.
45Erfindungsgemäß werden Schmierfette auf Seifenbasis, die neben Mineralöl und/oder synthetischem Öl 30 bis 80 Masse-% Glykole und/oder niedermolekulare Polyglykole, 0 bis 10 Masse-% Wasser 0,1 bis 1,0 Masse-% Korrosionsinhibitor und 0,5 bis 5,0 Masse-% mindestens eines schmierwirksamen EP-Zusatzes enthalten, fürIn accordance with the invention, soap-based greases containing, in addition to mineral oil and / or synthetic oil, 30 to 80% by weight glycols and / or low molecular weight polyglycols, 0 to 10% by mass water 0.1 to 1.0% by mass corrosion inhibitor and 0.5 to 5.0% by weight of at least one lubricious EP additive, for
