How To Calculate Reduction Ratio | Ehow Uk

Calculate the reduction ratio by dividing output torque by input torque. If 50 foot-pounds on the output results from 10 foot-pounds on the input, the reduction ratio is 5 to 1. This is similar to counting gear teeth. In that case, a 42-tooth gear driven by a 14-tooth gear calculates to 42/14, or a 3-to-1 reduction ratio.
