INVESTIGATION OF EFFECTS OF THE BEARING WIDTH/ DIAMETER RATIO ON PERFORMANCE OF A DYNAMICALLY-LOADED RADIAL JOURNAL BEARING

摘要

In this study investigation has been made on performance of a dynamically-loaded bearing under the influence of the bearing width/diameter ratio (B/D), the feature which is quite important to the manufacturers of radial journal bearings. With the increase of 0.5,0.75 and 1 in the B/D ratio for a dynamically-loaded radial journal bearing, corresponding variations of minimum bearing clearance, peak oil film pressure, friction torque, oil flow rate and hydrodynamic power losses on the bearing were investigated. The effects of B/D ratio on the bearing performance are presented graphically.
