Concept explainers

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 gear box for the worm gears has an effective surface area of0.25 m2. A fan is mounted on the worm shaft to circulate air over the surface of the fins. The coefficient of heat transfer can be taken as 25W/m2° C. The permissible temperature rise of the lubricating oil above the atmospheric temperature is 45° C. The coefficient of friction is 0.035 and the normal pressure angle is 20°. Calculate the power transmitting capacity based on thermal considerations.
