Gear Ratio Calculator.

A gear reducer increases torque and decreases speed. A gear

increaser reduces torque and increases speed. This calculator

determines output torque and speed for a speed increaser.

To find the output torque and speed of a gear increaser, use
the

equations:

Ouput Torque = Input Torque x Ratio of Gear Increaser

Torque is measured in Inch Pounds

Output Speed = Input Speed / Ratio of Gear Increaser

Example: A gear increaser with 1000 in/lbs of input
torque, an input

speed of 2000 RPM, and a ratio of .20:1
is:

Output Torque = 1000 x .20

Output RPM = 2000 / .20

Calculated out this gives an output torque of 200 in/lbs and
an output

speed of 10,000
RPM. (rounded to the nearest
10,000th)
