![]() Schematic of Simple Gear Train |
A Simple Gear-Train is a number of Simple Gear-Pairs in series. Each rotating shaft has only one gear. Simple Gear-Trains are used to:
The image to the left shows a schematic of a 'Simple Gear Train'. Notes for Simple:

'Monobloc Machines' This is a schematic of the gears you frequently find on a 'Monobloc' machine. Monobloc are often use for Filling, Capping, Labelling, Coding, Orientating and many other high-speed packaging applications. Monobloc machines use Simple Gear-Trains to transmit the motion from one 'wheel', or 'head' to the next. See Also: the YouTube Video: http://youtu.be/fvRp2lC1aXw |
![]() Schematic of Compound, Three-Stage, Gear Train |
A 'Compound Gear Train' has at least:
Compound Gears are used to:
The image to the left shows a Compound Gear Train. There is more than one gear-pair and two shafts have two gears. Therefore, it agrees the definition of the Compound Gear Train. |

A 'Reverted Gear Train' has:
It is a Compound Gear with, two Gears-Pairs, and a special condition that makes the total number of teeth of the first gear-pair equals the number of teeth of the second-gear-pair, when the module is the same. The image to the left shows a Reverted Gear Train. There is more than one gear-pair, two shafts, and the input and output shafts are collinear. Therefore, it agrees the definition of the Reverted Gear Train. See Also: Simple Gear-Pair, Simple Gear-Trains, Planetary Gear-Trains
