Synthesis and Performance Characterization of Nanolubricants Proposed for Heavy Load Ball Bearing
Currently, nanofluids have been found to have enriched physical and thermal properties such as thermal conductivity, viscosity and convective heat transfer coefficients. The aim of this research is to analyse the performance characteristics of punga oil and plastic oil based nanolubricants. The nanoparticle of graphite with 0.1% weight was added to the base oils. Hydraulic oil of VG32 is used as standard oil to compare the performance with the nanolubricants. Basic properties such as viscosity, flash and fire point were measured for the prepared nanolubricants. Coefficient of friction for the selected oils was measured with help of reciprocating friction monitor and load wear index was also measured with the help of four ball tester. The performance of these oils for load ball bearing lubrication was carried out numerically with the help of Comsol software and its analytical validation was done with the help of MATLAB software. From the observed results it was found that, the power loss was decreased by about 77.4% and 78% by plastic oil and plastic oil based nanolubricant respectively and load carrying capacity was also decreased by about 78.3% and 78.8%.
