A 50 mm transmission shaft transmitting 15 kW power at 200 rpm is supported on two deep grove ball bearings 750 mm apart and two gears are key to it. The pinion and gear have 30 and 100 teeth respectively. The pinion is located at 100 mm to the left of the right bearing, whereas the gear is located at 150 mm to the right of the left bearing The module and pressure angle of gear is 5 and 200 involute. Pinion delivers power horizontally to the right and gear received power in a vertical direction from below as shown in Figure l. The expected life of 15,000 h assumes the torque is the same for both pinion and gear and the bearings are under radial load only. Find the pitch diameters of pinion and gear. The torque transmits by the shaft Find force FC and FD Select suitable deep groove ball bearings at A and B

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.
