can you explain the theroy behind gear trains and there uses?

Gear trains are used to trade RPM and rotational speed for torque.
An example would be that a lot of electric AC motors run at 1700 RPM. Given a horsepower (1/2 HP for example), a torque would be generated at that speed.
If the required speed is less, a gear train would be used to step the rotational speed down to a lower RPM, while raising the torque that is transmitted. The power remains the same (less the inefficiencies added by the friction of the gear train).
A transmission in a car is a gear train (a variable one at that). Machine tools use gearing to change cutting tool speeds.

The simplest possible answer is: gears work on the same principle as do levers. A physics book will confirm this, and give much more details.
