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 …

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 …

The distribution of lubricating oil in the bearing cavity is of great significance to bearing
lubrication and cooling. A new idea is provided to further study the ball bearings lubrication …

It is of great relevance to maintain an adequate and continuous lubricant oil supply to each
contact region in successive rolling point contact systems, such as rolling bearings, rolling …

Lubricating characteristics of support bearings in gearboxes would greatly affect operational
performances of gear transmission systems. To discuss the lubricating characteristics of oil …

Special vehicles often work in low temperature environment. Nevertheless, the lubrication
flow field and oil distribution of gear in low temperature environment is still unclear. A …

Oil-phase distribution inside roller bearings with under-race lubrication is a key element for
bearing lubricating and cooling, and it determines the bearing's hydraulic loss, which may …
