A horizontal belt conveyor arranged as shown in the figure P1 below operates at a speed of 270 fpm and requires 25 Hp at the 40-inch-diameter driving drum. The drum receives power from a countershaft through a pair of spur gears. A motor operating at 860 rpm delivers power to the countershaft through a roller chain. The mechanical efficiency of the chain drive is 94 % and of the gears is 96 %. a) Determine the Hp of the motor you would recommend. b) Determine the rpm of the driving drum and the countershaft. c) Calculate the number of teeth on the large sprocket required running the conveyor belt at the speed specified. d) Determine the transmitted torque on the countershaft, in in-lb.

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.
