Investigation of the High Speed Rolling Bearing Temperature Rise With Oil-Air Lubrication

Journal of Tribology, 2011
The oil-air lubrication system has been widely used for rolling ball bearing. However, as the rotation speed increases, the temperature rise will increase dramatically, resulting in shortening the service life of the ball bearing. The existing literature has offered valuable fundamental data about the oil-air lubrication of rolling bearing; however ...

Effect of lubricant selection on the wear characteristics of spur gear under oil-air mixed lubrication

Tribology International, 2022
Abstract The helicopter transmission system generally employs oil injection lubrication, while the tooth surface often operates under mixed lubrication. In the case of mixed lubrication, the relationship among the fluid flow, rough contact, and material wear renders it quite difficult to establish a predictive model for wear and lubrication coupling.
