v11 v12 6 6 '''Why do we use gears?'''\\ 7 7 8 The main purpose of gears is to transfer mechanical energy from one shaft to another. Gears can be used to interchange ''rotational speed'' and ''torque''. ''Rotational speed'' is the speed at which the gear and its shaft are rotating, and ''torque'' is the rotational force the gear applies. By chang ethe ''gear ratio'', you can change the ''rotational speed'' and ''torque'' of the shafts.8 The main purpose of gears is to transfer mechanical energy from one shaft to another.

We use gearsand gearboxes to exchange speed for more torque.10 On our robotics team, most of [wiki:Motors our motors] rotate their shafts too fast and with not enough torque for our applications. We use gears, sprockets and chain, belts and pulleys, and gearboxes to exchange speed for more torque. 11 11 12 12 Gearing can also help adjust the placement of a motor with respect to the axle you wish to rotate using ''idler gears'', ''belts'', etc. You will see some examples throughout the lessons.
