Gear Train

A gear train is formed by mounting gears on a frame so 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; this provides a smooth transmission of rotation from one gear to the next.

• A gear train is two or more gear working together by meshing their teeth and turning each other in a system to generate power and speed

• It reduces speed and increases torque                             

• Electric motors are used with the gear systems to reduce the speed and increase the torque

Types of gear train

- Simple gear train

- Compound gear train

- Epicyclic gear train

- Reverted gear train
