Q: A full film hydrodynamic journal bearing is required for a shaft supporting a radial load of 2200N, whilst rotating at 1000rpm.The nominal diameter of the shaft is 40mm.The lubricant can be supplied at an inlet temperature of 60°C, using an available cooling system. Select a suitable lubricant as SAE30 and appropriate values for the radial clearance and bearing length as 20mm. Determine the overall temperature rise in the bearing and the flow rate of lubricant required. Establish that the selected design lies within the optimum zone for minimum friction and maximum load on the minimum film thickness ratio chart.
