Gear Wikipedia
A gear or cog is a rotating machine part having cut teeth or in the case of a cogwheel inserted teeth called cogs which mesh with another toothed part to transmit torque Geared devices can change the speed torque and direction of a power source Gears almost always produce a change in torque creating a mechanical advantage through their gear ratio and thus may be considered a simple
