Abstract: The noise of a journal bearing with the compound groove textures is studied based on computation fluid dynamic (CFD) theory and broadband noise source theory. In doing so, the acoustic power levels of the noise for the ...

Abstract: Operation parameter influences on the behavior of the gaseous bubble in the lubricant for a groove textured journal bearing are studied under the consideration of the thermal effect of the bearing–shaft system. The influence ...

Abstract: Effects of groove textures on the performances for gaseous bubbles in the lubricant used for a textured journal bearing is studied under the consideration of thermal effect of lubricant. The Reynolds, energy, and ...

Abstract: The graphite-MoS2 coated on GCr15 bearing steel is prepared through air spraying and its tribological performances are investigated experimentally. Then its coefficient of friction (COF) and wear scar width (WSW) are ...
