for Output Torque and Speed

Gear Reducer Calculator.

A gear reducer increases torque and decreases speed. A gear

increaser reduces torque and increases speed. This calculator
is for

a gear reducer.

How do you calculate the output torque of a gear reducer?

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

gear ratio formulas:

Ouput Torque = Input Torque x Ratio of
Gear Reduction

Torque is measured in Inch Pounds

Output Speed = Input Speed / Ratio of Gear Reduction

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

speed of 2000 RPM, and a reduction ratio of 3.5:1
is:

Output Torque = 1000 x 3.5

Output RPM = 2000 / 3.5

Calculated out this gives an output torque of 3,500 in/lbs and an

output speed of 571.4286 RPM. (rounded to the nearest
10,000th)
