De onderhavige uitvinding heeft betrekking op eau smeer-irdddelcanpos itie die als basisolie een polyoxyalkyleenvloeistof omvat, en op een tandwielkast die deze compositie bevat.The present invention relates to a lubricating oil composition comprising as base oil a polyoxyalkylene liquid and a gearbox containing this composition.

Een smeermiddel voor een tandwielkast moet onder de 5 ongunstigste omstandigheden die tijdens bedrijf van de tandwielkast worden ondervonden, kunnen funcitioneren. Het dient derhalve aan ijzer, bij aanwezigheid van zout water, goede bescherming tegen corrosie te geven, drabvrije werking bij temperaturen boven 120 °C te verzekeren, alsmede weinig schuim-10 vorming en lage wrijvingsverliezen te veroorzaken.A gearbox lubricant must be able to function under the 5 most unfavorable conditions encountered during gearbox operation. It should therefore give iron, in the presence of salt water, good protection against corrosion, ensure sludge-free operation at temperatures above 120 ° C, as well as cause little foaming and low friction losses.

Het is gebleken dat aan deze eisen wordt voldaan wanneer in de polyaxyalkyleenbasisvloeistof gebruik wordt gemaakt van een speciale ccmfoinatie van toevoegsels.It has been found that these requirements are met when using a special additives co-polymerization in the polyaxyalkylene base fluid.

Volgens de uitvinding omvat een smeermiddelcaipositie die 15 aan bovengenoemde eisen voldoet als basissmeerolie een polyoxy-alkyleenvloeistof en als toevoegsels kleine hoeveelheden van: 1) een thiodiarylamine; 2) een gealkyleerde diarylamine, en 3) een N-acylsarcosine.According to the invention, a lubricant cap position satisfying the above requirements comprises as a lubricating base oil a polyoxyalkylene fluid and as additives small amounts of: 1) a thiodiarylamine; 2) an alkylated diarylamine, and 3) an N-acyl sarcosine.

20 Het gebruik van een polyoxyalkyleenvloeistof als basisolie in smeermiddeloomposities voor tandwielkasten is reeds bekend j uit het Britse octrooischrift 1.294.856. Daarin wordt vermeld j dat deze vloeistoffen in vergelijking met minerale smeeroliën bij hoge temperaturen een uitstekende oxidatiestabiliteit 25 bezitten. Verder kunnen deze composities toevoegsels bevatten zoals (1) anti-oxidanten en toevoegsels zoals (3) roestwerende en wrijving-reducerende toevoegsels.The use of a polyoxyalkylene liquid as base oil in gearbox lubricant positions is already known from British Patent Specification 1,294,856. It is stated therein that these liquids have excellent oxidation stability compared to mineral lubricating oils at high temperatures. Furthermore, these compositions may contain additives such as (1) antioxidants and additives such as (3) anti-rust and friction-reducing additives.

Thans is verrassenderwijs gebleken dat door een deel van toevoegsel (1) in dergelijke composities te vervangen door 30 toevoegsel (2) uitstekende anti-asddanteiganschappen worden 9 8300983 - 2 - verkregen, en dat bij de hoge temperaturen die tijdens continubedrijf van de tandwielkasten worden ondervonden, weinig of geen drab wordt gevormd.It has now surprisingly been found that by replacing part of additive (1) in such compositions with additive (2), excellent anti-asdantant properties are obtained, and that at the high temperatures experienced during continuous operation of the gearboxes. little or no sludge is formed.

Geschikte polyoxyalkyleenvloeistoffen zijn copolymeren of 5 condensatieprodukten van een alkyleenoxide, in het bijzonder etheenoxide en propeenoxide, zoals beschreven in het Britse octrooischrift 1.294.856, welke bij voorkeur viscositeiten hebben van 140-230 nm2/s bij 38°C.Suitable polyoxyalkylene fluids are copolymers or condensation products of an alkylene oxide, in particular ethylene oxide and propylene oxide, as described in British Patent Specification 1,294,856, which preferably have viscosities of 140-230 nm2 / s at 38 ° C.

In de onderhavige composities is de basisvloeistof bij ΙΟ voorkeur een polyprqpeenglycol, welke bij voorkeur een moleculair-gewicht van ongeveer 2000 heeft en een viscositeit van ongeveer 160 mm2/s bij 38°C, aangezien in deze vloeistof toevoegsel (3) aan ferrcwnetalen een betere bescherming tegen corrosie geeft dan in de copolymeren van etheenoxide en propeenoxide, welke 15 volgens bovengenoemde octrooiaanvrage de voorkeur genieten.In the present compositions, the base fluid is preferably a polypropylene glycol, which preferably has a molecular weight of about 2000 and a viscosity of about 160 mm 2 / s at 38 ° C, since in this fluid additive (3) to ferrous metals is better corrosion protection then gives in the copolymers of ethylene oxide and propylene oxide, which are preferred according to the above-mentioned patent application.

Geschikte toevoegsels (1) worden ook in bovengenoemde octrooiaanvrage beschreven, waarbij fenothiazine en gesubstitueerde fenothiazinen, zoals gealkyleerde fenothiazinen, de voorkeur genieten.Suitable additives (1) are also described in the above patent application, with phenothiazine and substituted phenothiazines, such as alkylated phenothiazines, being preferred.

2o Geschikte toevoegsels (2) worden beschreven in het2o Suitable additives (2) are described in the
