V-Belt Drive Problems. Do any three.
a. A .33-hp (0.25-kW), 1750-r/min motor is to operate a furnace blower having a shaft speed of approximately 765 r/min. The center distance between the motor and blower shafts is approximately 13.5 in. (340 mm). Select a suitable V-belt.
b. A .5-hp (0.37-kW), 1160-r/min motor is used to operate a drill press. The spindle speed is 520 r/min 65 r/min. The center distance between the motor and blower shafts is approximately 22 in. (550 mm). Select a suitable V-belt.
c. A 1.5-hp (1.1-kW), 1750-r/min motor is to operate a band saw whose flywheel turns at approximately 800 r/min. A pulley attached to the flywheel shaft connects, by means of a V-belt, to the pulley on the motor shaft. Center-to-center distance of shafts is 13.5 in. (340-mm). Calculate the size of the V-belt required.
d. A .5-hp (0.37-kW), 1750-r/min motor drives a power hacksaw. The shaft on the hacksaw is to run at approximately 750 r/min, and the center-to-center distance of the shafts is 15.5 in. (400 mm). Calculate the size of V-belt required.
e. A .75-hp (0.6-kW), 1750-r/min motor is used to drive a punch machine whose flywheel turns at approximately 600 r/min. A pulley is attached to the flywheel shaft and connects to the motor pulley by means of a V-belt. Center-to-center distance is 17 in. (430 mm). Calculate the size of V-belt required.
