Pulley RPM, Diameter and Teeth Calculator

Dear Readers,

Pulleys and belt transmissions are used most commonly in machineries.

Below are some calculators based on the equation:

n1d1=n2d2 or n1t1=n2t2 

Where, n1= RPM of Driving Pulley,

            n2= RPM of Driven Pulley,

            d1= Diameter of Driving Pulley,

            d2= Diameter of Driven Pulley,

            t1 = No. of teeth of Driving Pulley,

            t2 = No. of teeth of Driven Pulley.

Below calculators will help you to find fourth value if any of three values are known.
