A transmission or gearbox provides speed and torque conversions from a rotating power source to another device using gear ratios, including for a motor vehicle partly because of the limitations of internal combustion engines. Torque converters, hydraulics, electrical power and hybrid configurations may also be used for the same purpose.

Gearboxes have found use in a wide variety of different—often stationary—applications, such as wind turbines.

Bevel Based Gearboxes : bevel ratio is most important factor to decide transmission of mechanical transmission power

Transmissions are also used in agricultural, industrial, construction, mining and automotive equipment. In addition to ordinary transmission equipped with gears, such equipment makes extensive use of the hydrostatic drive and electrical adjustable-speed drives.
