Formula

## Gear Ratio Fundamentals Gears trade speed for torque (or vice versa) while transmitting rotational power. ### Formulas **Gear Ratio = N2 / N1** (driven teeth / driver teeth) **Output Speed = Input Speed / Gear Ratio** **Output Torque = Input Torque x Gear Ratio** (assuming no losses) A ratio greater than 1 is a speed reduction (torque multiplication). A ratio less than 1 is a speed increase (torque reduction).

Esempio Risolto

A 20-tooth driver meshing with a 60-tooth driven gear, input 1800 RPM at 50 N-m.

  1. 01Gear ratio = 60 / 20 = 3.0 (speed reduction)
  2. 02Output speed = 1800 / 3.0 = 600 RPM
  3. 03Output torque = 50 x 3.0 = 150 N-m (ideal)
  4. 04Actual torque is slightly less due to mesh efficiency (typically 95-99% per stage).
