I Want to Learn About Gear Train

A gear train or gear set is a machine element of a mechanical system formed by mounting two or more gears on a frame such that the teeth of the gears engage.


Gear teeth are designed to ensure the pitch circles of engaging gears roll on each other without slipping, providing a smooth transmission of rotation from one gear to the next.


Features of gears and gear trains include:

  • The gear ratio of the pitch circles of mating gears defines the speed ratio and the mechanical advantage of the gear set.

  • A planetary gear train provides high gear reduction in a compact package.

  • It is possible to design gear teeth for gears that are non-circular, yet still transmit torque smoothly.

  • The speed ratios of chain and belt drives are computed in the same way as gear ratios.
