Description

Schmiermittel Die Erfindung betrifft die Zusammensetzung eines Schmiermittels auf der Basis eines Gemisches von Sulfiden und Lacken, Kunst- oder Naturharzen.Lubricants The invention relates to the composition of a lubricant based on a mixture of sulphides and lacquers, synthetic or natural resins.

Es ist bekannt, Molybdän-, Titan-, Zinn-, Zirkonium- oder Wolframdisulfid zusammen mit Glyzerin oder Äthylenglykol als Schmiermittel zu verwenden. Im Falle einer Vermischung dieses Schmiermittels mit Öl 0d. dgl. wird die beabsichtigte Schmiermittelzusammensetzung und damit der Schmiereffekt entscheidend verändert.It is known to have molybdenum, titanium, tin, zirconium or tungsten disulfide to be used as a lubricant with glycerine or ethylene glycol. In the event of mixing this lubricant with oil 0d. The like becomes the intended lubricant composition and thus the lubrication effect changes decisively.

Ferner ist es bekannt, daß das Reibungsverhalten von Kunststoffen, wie Ebonit, durch den Zusatz von Molybdändisulfid günstig beeinflußt wird.- Es ist auch bekannt, Körper mit selbstschmierender Oberfläche herzustellen, die aus Kunstharz, Füllstoffen und wenigen Prozent Molybdän-, Zirkonium-, Titan- oder Wolframdisulfid bestehen.It is also known that the frictional behavior of plastics, like ebonite, is favorably influenced by the addition of molybdenum disulphide.- It is also known to produce bodies with a self-lubricating surface made of synthetic resin, Fillers and a few percent molybdenum, zirconium, titanium or tungsten disulfide exist.

Auf Grund der Erfindung sind die bei der eingangs genannten Schmiermittelbasis verwendeten Sulfide solche der Metalle der II. Gruppe des Periodischen Systems, Barium, Kadmium, Kalzium, Magnesium, Strontium oder Zink.Due to the invention, the lubricant base mentioned at the beginning sulfides used are those of the metals of Group II of the Periodic Table, Barium, cadmium, calcium, magnesium, strontium or zinc.

Bei der erfindungsgemäßen Zusammensetzung des Schmiermittels wird dieses auch durch die zusätzliche Verwendung weiterer Schmiermittel, wie Öl, nicht verändert. Durch Vergleichsversuche zwischen Zinksulfid und Molybdändisulfid als schmierender Bestandteil von Nitrozelluloselack und Kunstharzlack (Alkydharzlack) wurde die besondere Eignung der Sulfide von Metallen der II. Gruppe des Periodischen Systems für die Zwecke der Erfindung erwiesen. Dabei wurden in 2 Gewichtsteilen Lack 1 Gewichtsteil Zn S oder MoS2 eingebracht und die Bestandteile gut vermischt. Mit den so pigmentierten Lacken wurden die Lagerschalen der Almen-Wieland-Maschine derart behandelt, daß die Dicke des trockenen Schmiermittehfilmes 30 bis 50 My betrug. Gemessen wurde 1. die bis zum Bruch des Zapfens ausgeübte Belastung bei Zusatzschmierung mit Schneidöl; 2. die Belastung bis zum Bruch des Zapfens, wobei das Öl erst nach 500 kg Belastung zugeführt wurde; 3. die Länge eines Dauerlaufes bis zum Bruch des Zapfens, nachdem bei 500 kg Belastung 01 zugeführt wurde und bei gleichbleibender Belastung weitergefahren wurde. Die Versuchsergebnisse werden im einzelnen durch die nachstehende Tabelle belegt: Dauerlauf, nach 500 kg Zusätzlich Schneidöl Erst nach 500 kg Belastung 01 eingefüllt Schmiermittel eingefüllt Belastung öl eingefüllt und mit dieser Belastung Bruch nach kg Bruch nach kg weitergefahren Bruch nach Minuten Nitrozelluloselack mit Mo S2 1. 1150 1. 1400 1. 25 Minuten 2. 1000 2. 1350 2. 24 Minuten 3. 1050 3. 1500 3. 23 Minuten Nitrozelluloselack mit Zn S 1. 1250 1. 1500 1. 28 Minuten 2. 1300 2. 1500 2. 26 Minuten 3. 1200 3. 1550 3. 29 Minuten Kunstharzlack mit Mo S2 1. 1250 1. 1500 1. 26 Minuten 2. 1200 2. 1450 2. 24 Minuten 3. 1150 3. 1550 3. 27 Minuten Kunstharzlack mit Zn S 1. 1200 1. 1500 1. 28 Minuten 2. 1100 2. 1600 2. 29 Minuten 3. 1300 3. 1450 3. 27,5 Minuten In Nitrozelluloselack betrug die Bruchbelastung mit Zn S durchschnittlich 1230 kg, mit Mo S2 1060 kg. Wurde das Öl erst nach 500 kg Belastung zugeführt, so lag die Bruchbelastung mit Zn S im Durchschnitt bei 1520 kg, mit Mo S2 bei 1420 kg.With the composition of the lubricant according to the invention, this is not changed even by the additional use of other lubricants, such as oil. Comparative tests between zinc sulphide and molybdenum disulphide as a lubricating component of nitrocellulose lacquer and synthetic resin lacquer (alkyd resin lacquer) have shown the particular suitability of the sulphides of metals of Group II of the Periodic Table for the purposes of the invention. In this case, 1 part by weight of Zn S or MoS2 was introduced into 2 parts by weight of lacquer and the components were mixed well. The bearing shells of the Almen-Wieland machine were treated with the paints pigmented in this way in such a way that the thickness of the dry lubricant film was 30 to 50 μm. Measured were 1. the load exerted up to the breakage of the journal with additional lubrication with cutting oil; 2. the load up to the breakage of the pin, whereby the oil was only added after a load of 500 kg; 3. The length of an endurance run until the pin breaks, after 01 was added at 500 kg load and continued driving with the same load. The test results are substantiated in detail by the following table: Endurance run after 500 kg Additional cutting oil Only filled in after a load of 500 kg 01 Lubricant filled in load oil filled in and with this load Break after kg Break after kg continued Break after minutes Nitrocellulose lacquer with Mo S2 1. 1150 1. 1400 1. 25 minutes 2. 1000 2. 1350 2. 24 minutes 3. 1050 3. 1500 3. 23 minutes Nitrocellulose lacquer with Zn S 1. 1250 1. 1500 1. 28 minutes 2. 1300 2. 1500 2. 26 minutes 3. 1200 3. 1550 3. 29 minutes Synthetic resin paint with Mo S2 1. 1250 1. 1500 1. 26 minutes 2. 1200 2. 1450 2. 24 minutes 3. 1150 3. 1550 3. 27 minutes Synthetic resin lacquer with Zn S 1. 1200 1. 1500 1. 28 minutes 2.100 2. 1600 2. 29 minutes 3. 1300 3. 1450 3. 27.5 minutes In nitrocellulose lacquer, the breaking load with Zn S averaged 1230 kg, with Mo S2 1060 kg. If the oil was only added after a load of 500 kg, the breaking load with Zn S was on average 1520 kg, with Mo S2 at 1420 kg.

In Kunsthärzlack lagen die entsprechenden Werte für Zn S und Mo S2 bei 1200 kg und bei Einsetzen der Ölzusatzschmierung nach 500 kg Belastung bei 1520 bzw. 1500 kg. Im Dauerlauf erfolgte der Bruch des Zapfens nach Zufuhr von Öl bei 500 kg Belastung mit Zn S in Nitrozelluloselack im Durchschnitt nach 27,6 Minuten, mit MoS2 jedoch nach durchschnittlich 24 Minuten. Mit Zn S in Kunstharzlack ging der Zapfen bei Zufuhr des Öles nach 500 kg Belastung nach durchschnittlich 28,1 Minuten Dauerlauf zu Bruch. Mit MoS2 in. Kunstharzlack erfolgte der Bruch bei sonst gleichen Laufbedingungen durchschnittlich nach 25,6 Minuten. Das neue Schmiermittel erweist sich also zumindest im Dauerlauf, auf den es ja ankommt, als überlegen, wenn z. B. mit Kunstharz als Basis die ermittelten, kurzzeitig andauernden Höchstbelastungen zwischen Zn S und Mo S2 nicht oder nur mäßig zugunsten von Zn S differieren.The corresponding values for Zn S and Mo S2 were in synthetic resin varnish at 1200 kg and when using additional oil lubrication after 500 kg load at 1520 or 1500 kg. In the endurance run, the pin broke after the supply of oil at 500 kg load with Zn S in nitrocellulose lacquer on average after 27.6 minutes, with MoS2, however, after an average of 24 minutes. With Zn S in synthetic resin lacquer went the pin with the supply of oil after 500 kg load after an average of 28.1 Minutes of continuous running broken. With MoS2 in. Synthetic resin paint, the break occurred otherwise same running conditions after an average of 25.6 minutes. The new lubricant proves to be superior, at least in the endurance run, which is what counts, if z. B. with synthetic resin as a basis, the determined, short-term maximum loads between Zn S and Mo S2 do not differ or only differ moderately in favor of Zn S.
