The lubrication of the mechanical components reduces friction, and increases the efficiency
and the reliability. However, the interaction of moving components with the lubricant leads to …

Lubrication characteristics can greatly affect the service performances of ball bearings. To
further clarify the variation law of oil–air distribution in bearing cavity, a new simulation …

A fluid-structure coupling numerical model of an oil-jet lubricated cylindrical roller bearing
(CRB) in a high-power gearbox is developed, in which the volume of fluid (VOF) method and …

Lubricant oil is crucial to the rolling bearings as the main medium of lubricating, cooling,
cleaning, and so on. The oil starvation in and around the contacts is harmful to the …

The air-lubricant interaction causes aeration which influences lubrication mechanisms in
rolling-element-bearings. The goal of this paper is to develop a Computational Fluid …

The acquisition of complex fluxes inside a Tapered Roller Bearing (TRB) via Particle Image
Velocimetry (PIV) is an experimental challenge. This can be successfully performed by …

With the development of major equipment towards high power density, the bearing speed is
getting higher and higher. In the oil-jet lubrication mode, the fluid in the bearing chamber is a …

Actual volume of the supplied oil that functions as a lubricant in the contact regions of rolling
bearings is intriguing and difficult to determine. In this study, we propose a novel …

Experimental studies on rolling-element bearing lubrication represent an ambitious
engineering challenge. In the present study, the design of a dedicated test rig to perform …
