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.

The multiple vee-belt drive illustrated in Figure Q5(b), has a groove angle of 40° and is required to transmit 17.4 kW from a pulley 165 mm in diameter to another pulley 330 mm in diameter which rotates at 390 rev/min. The coefficient of friction between the belt and the pulleys is 0.32 and the maximum permissible belt tension is 550 N for each of the five belts used. For this geometry and conditions, calculate: i) the torque on the smaller pulley; ii) the angle of lap (0s) required to achieve this power rating; iii) the ideal centre distance (C) for this angle of lap.
