Performance analysis of journal bearing operating on nanolubricants with TiO2, CuO and Al2O3 nanoparticles as lubricant additives

Abstract

Present experimental study investigate the performance analysis of Journal bearing operating on Nanolubricants prepared by adding TiO2, CuO and Al2O3 nanoparticles as lubricant additives in Avalon ISO Viscosity grade 46 oil. By adding nanoparticles, the viscosity of the lubricant oil is improved, and, in effect, a performance characteristic of journal bearing is enhanced. Nanoparticles used for present work is mixed with base oil with volume fractions of 0.25%, 0.5%, 1% and 2% with the help of mechanical agitator and ultrasonication. Journal bearing Test Rig TR-60 is used to experimentally investigate pressure distribution and load carrying capacity. Performance of bearing is measured at speeds 250 rpm, 500 rpm and at loads 300 N and 450 N. The results indicate a rise in maximum pressure and load carrying capacity of journal bearing by adding TiO2, CuO, and Al2O3 nanoparticles as lubricant additives compared to base oil without nanoparticles additives.
