Research on lubrication performance of micro-textured journal bearing based on fluent

Abstract

Abstract. The micro-textured surface technology has obvious effect on improving the lubrication performance of the journal bearing. In this paper, a 3D micro-textured journal bearing model is established by fluent and compared with non-textured smooth journal bearing. The effect of circumferential total texture and partial texture of different positions in bearing area on bearing lubrication performance is analyzed. Results show that circumferential total texture and partial texture can effectively improve the bearing capacity of bearing and reduce the friction coefficient, and there is a reasonable and effective range for the quantity, position and density of micro texture.
