Abstract (en)
[origin: WO8808874A2] A number of functional characteristics of a gear lubricant are improved by including within the lubricant an additive package comprised of (a) a treated zinc dithiophosphate and (b) an overbased carboxylate which is preferably borated. The additive preferably includes (c) an alkylamine, (d) a sulfurized olefin and (e) a polymeric foam inhibitor. The components of the package provide an interdependent synergistic improvement of numerous performance characteristics of the gear lubricant such as reducing copper strip corrosion, increasing thermal stability and reducing the amount of rust, and odor. The limited slip or anti-chatter performance of the oil is also improved.
