Abstract
Research is being focused on to find the influence of surface variations such as texturing or grooving on the bearing performances. Though, earlier it was restricted to the theoretical aspects alone, however, with the help of advance manufacturing techniques (laser surface texturing, etching, special grinding process, etc.), it has become possible to produce micro-textures or grooves on the surface of journal bearing. The objective of the present study is to numerically compare the influence of spherical texture and micro-grooving (longitudinal and transverse) on friction coefficient and average temperature of journal bearing at low and high eccentricity ratios. From the findings, it has been observed that the micro-grooving reduces the friction coefficient and average temperature is maximum in comparison with spherical texture.
