Abstract:
A lubricant composition of 40 to 95% of an oil having a kinematic viscosity at 100° C. of 3 to 7.5; 0.3 to 2% of an amine salt of a phosphorus compound obtained by reacting phosphorus pentasulfide with one or more alcohols having 4 to about 13, or 4 to 8, or 6, carbon atoms, with an alkylene oxide, and further with phosphorus pentoxide, and salting the resulting material with one or more amines having 2 to 20 or 12 to 24 carbon atoms; and an active-sulfur containing agent in an amount to provide 0.5 to 7% sulfur to the composition provides good wear protection to gears at a relatively low viscosity of the composition.

Claim (Index 1):
A lubricant composition comprising:\n (a) about 40 to about 95 percent by weight, or about 58 to about 80 percent by weight, of an oil having a kinematic viscosity at 100\u00b0 C. by ASTM D445 of about 3 to about 7.5, or about 3.6 to about 6, or about 3.5 to about 5 mm 2/ s; (b) about 0.3 to about 2 percent by weight of an amine salt of a phosphorus compound, or mixtures thereof, obtained by reacting phosphorus pentasulfide with one or more alcohols having 4 to about 13, or 4 to 8, or 6, carbon atoms, with an alkylene oxide, and further with phosphorus pentoxide, and salting the resulting material with one or more amines having 2 to 20 or 12 to 24 carbon atoms; and (c) a sulfurized olefin in an amount to provide about 0.5 to about 7, or about 0.5 to about 1.5, or about 1.5 to about 2, or about 3 to about 5, or about 2 to about 3, percent by weight sulfur to the composition; wherein said composition has a kinematic viscosity at 100\u00b0 C. by ASTM D445 of up to about 7.5 mm 2 /s.
