Multistage Gear Train Calculator
Calculate stage ratios, output speed, torque and rotation direction for a multistage external gear train.
Multistage Gear Train Calculator User manual
- Fill in the parameters or select the file according to the form, and check the unit and format first.
- A 20-tooth gear driving 60 teeth, followed by 20 teeth driving 40 teeth, gives a total reduction ratio of 6.
- Click the processing button to view the results, you can copy or download and save.
Calculation method and processing rules
Enter driving and driven tooth counts for each stage. Adjacent stages share a shaft; the entered efficiency applies to each stage.
scope of use
Supports up to 10 external gear stages. Does not model internal or planetary gears or assess tooth geometry, load capacity or mechanical safety.
