With a gear reduction, the output speed can be reduced while the torque is increased.

Sometimes, many spur gears are used at once to create very large gear reductions.

Also, locking any two of the three components together will lock up the whole device at a 1:1 gear reduction.

A low ratio, like 4 to 1, makes it easier to move away from a stop because of the mechanical advantage provided by gear reduction.

For all 4x4 models, the 2-speed transfer case 4x4-LOW range has a gear reduction of 2.72:1.

Worm gears are used when large gear reductions are needed.

Often a gear reduction is incorporated in order to be able to use a larger more efficient propeller.

In America, this process is termed gear reduction.

Most transfer cases have a gear reduction, known as 4-Low (or 4Lo), that can send more torque to your wheels.

Yet whatever vehicles he saw now were moving with an incredible slowness as though driven by some fantastic gear reduction.
