What is gear reduction ratio? - Quora

For a Geared mechanism, gear reduction ratio is ratio of the number of teeths on the pinion to the number of teeths on the gear. A gear reduction mechanism obviously, reduces the speed of the driven shaft to that of the driving shaft.This is usually employed in the systems where higher operating torques are required, at the expense of loss of speed.
