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
– Epicyclical gear train
– Reverted gear train
