| Abstract | ||
| Effect of non uniform permeability on the operational characteristics of finite width misaligned self lubricated journal bearing is investigated throughout this work. A modified boundary conditions for the oil film pressure is obtained by applying integral momentum equation to the oil film region in the bearing clearance. The performance characteristics of a misaligned self lubricated journal bearing with slenderness ratio of unity are obtained for various eccentricity ratios and misalignment angle. The bearing permeability is changed in radial and circumferential directions. Using self lubricated bearing with non – uniform permeability enhances the performance of such bearing. An decreases in maximum pressure and load carrying capacity, attitude angle, and coefficient of friction. Oil film extent increases with increasing the oil supply pressure. | ||
