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 ratio shown must transmit 10 horsepower (66000 lb in/s) from its input, which is rotating at a speed of 1200 revolutions per minute. It must increase the torque received at its input shaft 16 times. Spur gears with 20° pressure angle should be used. Input and output shafts should be aligned. The transmission should take up as little space as possible. The distance between the centers of the input shaft and the intermediate shaft (the one that loads gears 3 and 4) should be 10 inches. Determine the magnitude of the radial load that gear 4 exerts on gear 4. Write your answer in pounds.
