What is the transmission

In the mechanical systems with a transmission circular motion system, they are power transmission elements that allow the power and speed ratio to change gradually. The power levels on the transmission are known as gear in common language.

For example, in motor vehicles, the transmission transmits the power in the engine to the wheels and replaces the speed ratio by means of size and smallness of the wheels. In this case, high power and low speed are provided in the 1st level, while the second level is reversed relatively high speed and low power.
