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 16):
The method of  claim 13  wherein the lubricant composition is employed in a lubricated axle assembly characterized by a \u03bb value of less than 2.0, or 1.1 to 1.5, where \u03bb is defined as the ratio of elastohydrodynamic film thickness of the lubricant to the composite surface roughness of the gear surface.
