The design features and operating characteristics of a gear-lubricant test machine for high-temperature, high-speed service are described. Results on the load-carrying capacity (or scuff-limited load) of ten lubricants in combination with four types of test gears, at 165°F and 400°F lubricant supply temperatures, are presented. The load-carrying capacity was found to be strongly influenced by the lubricant type and the gear material. Depending upon lubricant type and gear material, it was found that the load-carrying capacity could decrease, either markedly or but slightly, with an increase in the lubricant supply temperature.
