Abstract

One of the main challenges that are widely faced is the maintenance of the journal bearing requires extra time and effort. Therefore, in this work a new design of journal bearings system was developed with low friction which would help with: A) relatively higher load as it would create duplicated pressure and B) Due to the use of the Nano Lubrication as one of the new system’s components, it will support an enhanced and persistent oil viscosity of the mechanical system which would support a mechanical system of a consistent temperature. To accomplish all the above, a mathematical model for the new journal bearing design was developed, the mathematical model was additionally resolved using Reynold’s equation and using the finite difference method. A MATLAB code was also developed to solve the governing partial differential equation to find journal-bearing parameters. The preliminary results of this work indicated an increase of pressure value of 50% as compared with the traditional bearing. Furthermore, the new design indicated a consistent oil viscosity/temperature when adding the Nanoparticles to the system and improve all bearing parameters.
