What Is An Idler

Idler gear refers to the gear that plays a transmission role between two transmission gears that are not in contact with each other, and meshes with these two gears at the same time, to change the rotation direction of the driven gear to make it the same as the driving gear. Its function is to change the steering but not the transmission ratio, which is called an idler.

Idler gears are also called overdrive gears. Its number of teeth has no effect on the value of the transmission ratio, but it will affect the steering of the last wheel.

Wheels that do not work have a certain energy storage effect, which is conducive to the stability of the system. Idler wheels are very commonly used in machinery, and they help to connect distant shafts. There is a very important function: change the output direction.

The wheels that mainly use their inertia are collectively called idlers.

Idler gear refers to a gear that is sandwiched between two gears and meshes with the two gears. Its function is only to change the direction of rotation of the front and rear gears without changing the transmission ratio or position.

The tension wheel appears in belt drive or chain drive. Its function is to tension the belt or chain, reduce the vibration and energy loss during its movement, and can change the position.
