What type of gear is in a clock?

In horology, a wheel train (or just train) is the gear train of a mechanical watch or clock. Although the term is used for other types of gear trains, the long history of mechanical timepieces has created a traditional terminology for their gear trains which is not used in other applications of gears.

What is a compound gear train used for?

The compound gear train allows you to multiply gear ratios together. Consequently, it is possible to create very large gear ratios and hence generate very large torque and low speeds from high-speed, low-torque motors, for example. The overall gear ratio is found by multiplying all the individual gear ratios together.
