What This Calculator Does
Calculate gear ratio, speed ratio, and torque multiplier.
It combines Driver Gear Teeth, Driven Gear Teeth to estimate Gear Ratio, Speed Ratio, Torque Multiplier.
Formula & Method
Gear ratio is GR=\frac{N_{driven}}{N_{driver}}, speed ratio SR=\frac{1}{GR}, and ideal torque multiplier equals GR.
Notation used in the formulas: R = Gear Ratio; x_{1} = Driver Gear Teeth; x_{2} = Driven Gear Teeth.
Method summary: inputs are normalized to consistent units, core equations are evaluated, then secondary values are derived and rounded for display.
Use this calculator for quick scenario analysis. Start with baseline values, change one driver at a time, and compare how sensitive the results are to each input shown above.
Inputs Used
- Driver Gear Teeth: Used directly in the calculation.
- Driven Gear Teeth: Used directly in the calculation.
