1) Description of Micro Gear
The micro gear always menas a small size transmission gear.
The module and external diameter are both small.
The micro gear usually used for compact system design.
2) Features of Micro Gear
The benefit of a micro gear train is that the teeth of the gear engage in small increments as opposed to the entire face engaging at once.
This reduces the noise that is normally caused as gears transfer power.
