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

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.& nbsp; (c) 2021 Elsevier Ltd.

Automated summary

The experimental study examined the performance of journal bearings operating on nanolubricants prepared by adding TiO2, CuO, and Al2O3 nanoparticles as lubricant additives. The results show that adding nanoparticles improves the viscosity of the lubricant oil and enhances the performance characteristics of the bearings, leading to increased maximum pressure and load carrying capacity.
