### THINGS TO KNOW ABOUT GEAR REDUCTION/ MAX

Gear reduction specifically refers to the speed of the rotary machine the rotational speed of the rotary machine is reduced by dividing it by a gear ratio greater than 1 1 A gear ratio greater than 1 1 is achieved when a smaller gear reduced size with fewer number of teeth meshes and drives a larger gear with greater number of teeth.
