The rolling bearing rotor (RBR) system is the kernel of many rotating machines, which affects
the performance of the whole machine. Over the past decades, extensive research work has …

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 …

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 …

This paper presents an experimental and analytical investigation into the lubrication of deep
groove ball bearing (DGBB) cage pockets. A custom acrylic replica of a cage segment was …

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 …

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 …
