Abstract
  • The goal of this paper is to evaluate how synthetic lubricants perform in an enclosed gearbox application when compared with a proven mineral oil. This is in an effort to improve gearbox efficiency with the desired effect of lower emissions from of improved energy output from power generation. Four liquid lubricants were studied to explore the performance impacts of oil composition on gearboxes in extreme temperature applications; one mineral oil, two PAO based oils, and one propylene glycol based lubricant. Fluids were evaluated based on standard tribological tests, coefficient of friction, and component level testing in a four-square gearbox test stand. The PAO based lubricants performed better than the mineral oil lubricant tribological tests but did not perform significantly better in component level testing. The propylene glycol based lubricant performed worse than the mineral oil based lubricant.
