Abstract (en)
[origin: WO2009134656A1] A lubricant composition that is especially useful under extreme conditions, such as in wind turbine gearboxes, comprises a mixed feed glycol; a polyol ester; two particular antioxidants; a phosphorus-based extreme pressure additive; a yellow metal passivator; and at least one specified corrosion inhibitor. The composition passes testing according to ASTM D665B even at 168 hours from initiation, and/or the SKF-Emcor Test Method DIN 51802:1990.
