How it works
Calculate output speed and torque for a gear reduction or multiplication.
Who it's for: Mechanical designers working with gearboxes and drive trains.
n_out = n_in / i; T_out = T_in × i × η.
Ratio i > 1 reduces speed and increases torque (reducer).
η is efficiency (0–1).
How to use
- Enter input speed, input torque, ratio i, and efficiency η.
- Read output speed and output torque.
