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 …

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

The cage structure with enhanced heat transfer function is proposed to improve the
temperature rise and heat dissipation issues caused by high bearing speed. By constructing …

Lubrication performance is crucial for operating and frictional feature of high speed rolling
bearing. In this paper, for B7008C angular contact ball bearing under outer ring guiding …

In this study, two-row tapered roller bearings (TBR) with different rib structures were tested
under the condition of loss of lubrication. It was found that the double-row TBR with outer …

The vortex formed around the rolling ball and the high pressure region formed around the
ball–raceway contact zone are the principle factors that barricades the lubricant entering the …

Aiming at air curtain effect in oil-air lubrication of high-speed angular contact ball bearings, a
numerical analysis model of oil-air two-phase flow in bearing cavity was constructed, which …

In order to improve the lubrication of rolling-sliding bearing, the oil-gas two-phase flow CFD
model of slider was established by using two-phase flow theory. The effects of different inlet …
