Wr^2 Jpinion = ------ 2g J = Inertia (lb-in-sec^2) W = weight of pinion (lbs) r = pinion radius (in.) g = gravity (386 in/sec^2) To calculate the Inertia of the load: Wr^2 Jload = ------- g J = Inertia (lb-in-sec^2) W = weight of load (lbs) r = pinion radius (in.) g = gravity (386 in/sec^2) Hope this is what your looking for.
