eng.gear-ratio-calc Calculator
Calculates gear ratio, output speed, torque multiplication, and efficiency loss from gear tooth count and material friction data. A gear reducer with ratio 10:1 multiplies torque 10× while dividing speed by 10, minus efficiency losses of 2–5% per stage.
Inputs
Teeth Drive
Reference formula or conversion factor shown for context.
Teeth Driven
Reference formula or conversion factor shown for context.
Rpm Drive
Reference formula or conversion factor shown for context.
Torque In
Rotational force (N·m) = force × perpendicular lever arm. Engine torque peaks at lower RPM; horsepower peaks higher.
Results
gear ratio
The proportional relationship between two quantities.
output RPM
Reference formula or conversion factor shown for context.
output torque (Nm)
Rotational force (N·m) = force × perpendicular lever arm. High torque at low RPM is ideal for hauling; high RPM suits high-speed applications.
power (kW)
Reference formula or conversion factor shown for context.
speed reduction
The computed rate of movement or processing.
torque multiplication
Rotational force (N·m) = force × perpendicular lever arm. High torque at low RPM is ideal for hauling; high RPM suits high-speed applications.
