The inspection plate came off easily and they saw the exposed gear train.

The power from the spring is used to turn the gear train and a generator.

It consists of gear train, which should be highly efficient and light weight.

Each turbine was connected to the drive shaft through a different gear train.

Cycle times of over 300,000 have been observed with these gear trains showing virtually no wear.

Thus, the speed ratio of a gear train also defines its mechanical advantage.

An electric motor drove both drums through a gear train so that one line paid out while the other was taken up.

The spring on the left is for the alarm, which has its own gear train and escapement.

They are the surfaces which, 5 times a second, lock the gear train of the watch and then transfer power to the balance wheel.

It does not require a separate gear train to arm and release the single stroke sounded.
