How to Calculate Percentage Reduction | Sciencing
The formula for finding the percentage of reduction is: P = a / b × 100. Where P is the percentage of reduction, a is the amount of the reduction and b is the original amount that was reduced. Subtract the final amount from the initial amount to find the amount of the reduction. For example, if your salary was $59,000 and it was reduced to ...

Caluclating Forging Reductions | Forging
A: Forging reduction is generally considered to be the amount of cross-sectional reduction taking place during drawing out of a bar or billet. The original cross-section divided by the final cross-section is the forging ratio (say 3:1). There is an equivalent reduction on upsetting for forgings being upset during forging (gear blanks, for example).

How to select gear ratio for a gear reducer?
For speed reduction the gear ratio is calculated using the equation: G = N MOTOR / N LOAD. where G is the gear ratio, and N is the angular velocity of the motor and the load. The way gear reducers work is that they essentially multiply the output torque of the motor. So for instance, a small motor with a gear reducer may be less expensive and ...

Gear Reduction in Electric Motors | Groschopp Blog
The "reduction" or gear ratio is calculated by dividing the number of teeth on the large gear by the number of teeth on the small gear. For example, if an electric motor drives a 13-tooth pinion gear that meshes with a 65-tooth gear, a reduction of 5:1 is achieved (65 / 13 = 5). If the electric motor speed is 3,450 rpm, the gearbox reduces ...
