Question:
Question 1 A full journal bearing is required for a shaft rotating at 1450 rpm. The lubricant can be supplied at an inlet temperature of 60oC using an available cooling system. 1.1 Determine the overall temperature rise in the bearing. 1.2 Determine the flow rate of lubricant required. 1.3 Establish that the selected design lies within the optimum zone for minimum friction and maximum load on the minimum film thickness ratio chart. Assume the following: Lubricant is SAE 10 L/D ratio of unity. Shaft nominal diameter = 40 mm. Load on the bearing = 2100 N.
Show all the calculations and state all the assumptions.
