Ride The Gear Train
Gear train calculations for engineer's lathes.
A free online program to calculate
gear trains for any screw thread
with the gear wheels that you own.
• Metric or imperial threads on
• Metric or imperial lathes
• Metric/imperial conversion gears.
• Feed rates, worm gears.
• Polygon Cutter gear ratios.
• Extensive help file, and video tutorials (below).
• Red button to search the help file.
• Gearboxes for various lathes are included.
• Custom gearboxes can be added.
• Extra Apps:
• Thread specifications and tapping drill sizes.
• Create tables of cutting speeds.
• Taper turning calculations.
• Charts for hardness of materials, heat treatment.
• Polygon cutter simulation.
• Electronic Leadscrew Calculations.
NEW 26-March-2023
• Polygon Cutter Calculations
Adjust gear ratios etc and watch the drawing change
in this animated simulation.
Then find the gear train
to give the required gear ratio.
Scroll down to the last orange button.
NEW April-2023
Step 2 simplified by dividing it into 2A and 2B.
Bugs caused by PHP programming language upgrade
to version 8, have now been fixed.
NEW 23-May-2023
• ELS Electronic Leadscrew Calculations
This takes the user through the steps necessary
to design software to drive an electronic leadscrew.

QUICK START GUIDE
• Try RUN if you want to see what the program does.
• Enter your own data in steps 1-5 then RUN.
• Step 1 : Choose the brand of your lathe.
• Step 2A: Design your gear train.
• Step 2B: Enter the gears you own for the gear train.
• Step 3 : Choose what you want to calculate
• Step 4 : Enter the % error you are willing to accept.
• Step 5 : For threads use ONE pitch entry method:
• Step 5A just enter the pitch or TPI, then RUN
• Step 5B produces a table for multiple thread sizes,
• Step 5C Use standard thread tables (eg UNF).
• Step 6 : Click RUN to execute the program.
• Return to menu to alter one or more items,
• RUN again.
EXTRA APPS
Orange buttons: apps that do not require lathe data.
