Optimize simple and compound gear trains for desired ratio, torque multiplication, speed reduction. Automatic stage calculation with efficiency and tooth count constraints.
Featured: Ratio • Stages • Torque • Efficiency
Optimal distribution
Enter input/output speeds to optimize
Ideal per stage: 3:1 to 5:1
Max practical: 10:1
Equal stages best for efficiency
Spur gears: 98–99% per mesh
Helical: 97–98%
More stages = lower total η
