Tribological Relationship for Sintered Bearing Using Taguchi Technique

Sintered bearing materials have been developed in order to be used as a journal bearing material without lubrication. This paper presents a study of influence of manufacturing and process parameters on friction and wear of bearing. Plan of experiments, based on Taguchi technique was used to acquire the data in a controlled way. An orthogonal array (L27) and analysis of variance were employed to investigate the influence of parameters of dry ferrous bearing. The objective is to establish a correlation between process and manufacturing parameters with friction and wear by multiple regression analysis. Finally, confirmation tests were performed to validate the relationship as suggested through experiments.
