An analytical investigation of the grooved journal bearing's performance with slip/no-slip texture bearing

The hydrodynamic journal bearings are widely used in different industries for high speed and high loads. Meanwhile, its performance and reliability is a big concern. Surface texturing is a suitable and an accepted way to improve its performance. In this paper, the altered Reynolds equation is done to calculate the load carrying capacity for convergent long journal bearings with slip and no-slip pattern. Furthermore, to investigate the load carrying capacity performance some defined parameters has changed to study their changes towards the performance of journal bearing, e.g. number of slip regions, depth of grooved, etc. From the results, it can be seen that increasing the slip and no-slip region length gives a promising impact towards the load carrying capacity for convergent long journal bearing. © 2006-2016 Asian Research Publishing Network (ARPN).
