Abstract:

Experimental gear load-carrying capacity results are presented on a variety of lubricants of different chemical classes and viscosities, with special reference to the effects of temperature and atmospheric environment. In an air environment, load-carrying capacity was found to decrease with increasing temperature until a minimum value was reached, and then to increase with a further increase in temperature. A significant reduction in load-carrying capacity was noted for each lubricant evaluated when the air environment was replaced with nitrogen. In addition, the increase in load-carrying capacity noted at the higher temperatures in an air environment was not evident when a nitrogen environment was used Author
