摘要:
A grease composition which has a good compatibility with boots made of rubber or thermoplastic elastomer, and which also gives enhanced endurance, low wear and low friction in use in constant velocity joints is disclosed. A grease composition is suggested comprising a) at least one base oil; b) 5% by weight to 40% by weight of at least one calcium sulphonate soap and/or calcium sulphonate complex soap as a thickener; and c) at least one molybdenum containing additive.

To solve the problem to provide for a new grease composition giving low wear and low friction primarily to constant velocity joints, a grease composition is suggested comprising a) a base oil composition; and b) 0.25% by weight to 5% by weight of at least one tri-nuclear molybdenum corn pound of the formula Mo3SkLnQz wherein L are independently selected ligands having organo groups with a sufficient number of carbon atoms to render the compound soluble or dispersible in the oil, n is from 1 to 4, k varies from 4 though 7, Q is selected from the group of neutral electron donating compounds such as amines, alcohols, phosphines, and ethers, and z ranges from 0 to 5 and includes non-stoichiometric values.

摘要:
A lubricating grease composed of a base oil combination comprising 10 to 35% of one or more poly &agr;-olefins, 3 to 15% of one or more synthetic organic esters, 20 to 30% of one or more naphthenic oils, the remainder of the combination being one or more paraffinic oils, the percentages being by weight of the total base oil combination and the ratio of the weight of the ester(s) in the combination to the weight of the poly &agr;-olefin(s) therein being not greater than 1:3; between 2 and 15 % by weight of the total grease of a lithium soap thickener, between 1 and 5% by weight of the total grease of a molybdenum dithiophospbate; between 1 and 5% by weight of the total grease of a zinc dialkyldithiophosphate; between 1 and 5% by weight of the total grease of a sulphur-free friction modifier, and some or all of the normal grease additives such as anti-oxidants, corrosion inhibitors, extreme pressure additives and tackiness agents.
