Abstract

Fluid bearings are frequently used in high load, high speed or high precision applications where ordinary ball bearings have short life or high noise and vibration. The investigation of nanotribology shows that the nanoparticles have unique property in lubrication and tribology, such as anti-wear, reducing friction, and high load capacity. There were some investigations on the tribological properties of lubricants with different nanoparticles added, and it was reported that the addition of nanoparticles to lubricant oil is effective anti-wear and reducing-friction performances. Recent experiments have revealed that addition of nanoparticles on lubricants results in better viscosity as compared to that of oils without addition of nanoparticles. Furthermore, these suspended solid particles in the commercial lubricants affect the load carrying capacity and other performance characteristics of journal bearings. In this paper Load Carrying capacity of Journal Bearing is studied by considering Sommerfeld and Reynolds boundary conditions. Solution of two dimensional Reynolds equation is done using Finite difference method and graph is obtained with help of MATLAB. Different combination of nanopartical concentration is taken and it had been found that by addition of nanopartical, higher the concentration of nanopartical results in high viscosity, High friction coefficient, high pressure distribution and ultimately high load carrying capacity of journal bearing.
