Gear Ratio Calculator
Calculate velocity reduction ratio, output RPM, and torque multiplication through intermeshed gears.
Input Parameters
Instant Real-time CalculationThe Gear Ratio Calculator is governed by Gear_Ratio = Teeth_Driven / Teeth_Drive = N_in / N_out | Torque_out = Torque_in × Ratio × Efficiency. It describes the mathematical and physical relationship between the material or mechanical parameters.
