A gearbox, also known as a gear
case or gearhead, is a gear or a hydraulic system responsible for
transmitting mechanical power from a prime mover (an engine or electric
motor) into some form of useful output. It is referred to the metal
casing in which a number of gears are sealed.
A gearbox is also a set of gears for transmitting power from one
rotating shaft to another. They are used in a wide range of industrial,
automotive and home machinery application.
Gearheads are available in different sizes, capacities and speed
ratios. Their main function is to convert the input provided by an
electric motor into an output of lower RPM and higher torque.
