(mechanical engineering) A system of interconnected gears.
And, if the output gear has fewer teeth than the input gear, then the gear train reduces the input torque. Source: Internet
For example, a bench vise consists of a lever (the vise's handle) in series with a screw, and a simple gear train consists of a number of gears ( wheels and axles ) connected in series. Source: Internet
If the output gear of a gear train rotates more slowly than the input gear, then the gear train is called a speed reducer. Source: Internet
The counting may be done electronically, usually in clocks with digital displays, or, in analog clocks, the AC may drive a synchronous motor which rotates an exact fraction of a revolution for every cycle of the line voltage, and drives the gear train. Source: Internet
The gear train also has a second function; to transmit mechanical power from the power source to run the oscillator. Source: Internet
The pulse of electricity that drove the pendulum would also drive a plunger to move the gear train. Source: Internet
