A 915 mm diameter driving pulley is used to drive 1,220 mm pulley. The center to center distance between the two pulleys is 3.5 mm and the output of the driven shaft is 85 HP. If a leather belt is used with a belt speed of 1,300 m/min coefficient of friction is 0.28, percent slip is 1.5% on each pulley, and loss due to friction on each shaft is 6%, calculate: (a) The rpm of each shaft: Ans. N1 = 459.13 rpm; N2 = 344.35 rpm (b) Difference in belt tension: Ans.(F1 - F2) = 3.11 kN (c) Size of 9.5 mm thick leather belt: Ans. b = 0.2475 mm; L = 10.6792 m
