Effect of Non – Uniform Permeability on the Operational


Effect of non uniform permeability on the operational characteristics of finitewidth misaligned self lubricated journal bearing is investigated throughout this work. Amodified boundary conditions for the oil film pressure is obtained by applying integralmomentum equation to the oil film region in the bearing clearance. The performancecharacteristics of a misaligned self lubricated journal bearing with slenderness ratio ofunity are obtained for various eccentricity ratios and misalignment angle. The bearingpermeability 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, andcoefficient of friction. Oil film extent increases with increasing the oil supply pressure.
