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.

Question

A 12-tooth external spur gear A, rotating clockwise, drives a gear B whose diametral pitch is 4.
The ratio of the speed of gear A to gear B is 2 to 1. The tooth proportions are standard 14-¹2°
brown and sharpe. (1) Placing the center of gear A on a vertical line above the center of B on the
same vertical line show and give the diameters of the pitch circles, addendum circles, and
dedendum circles. (2) Sketch in roughly enough of a tooth on each gear in contact at the pitch
point and indicate the face of the tooth, the flank of the tooth and the pitch point.
