Bet Sheave V-Belt Drive Eficiency 97% Chain Drive 90 Efficiency Calculate the torque, speeds, horsepower, and ratio at each shaft (Figure 3-13). This is a constant horsepower load. Although the horsepower delivered to the driven load at shaft #4 will be lower than the 5 HP supplied at shaft 1 because of effi- ciency losses inherent in the power transmission components, the required HP to move the load remains constant. Also determine the velocity of the conveyor pulley in feet.per minute for the following application. The gravel conveyor operates 24 hours per day.
