Have a question about GearTrain? Need an alternative?

GearTrain calculates the angular velocity of the final driven gear in a gear chain. The user enters the revolutions per minute and driection of the first driver gear along with information about the number of teeth of each gear in the series. The program will output the RPM and direction of the final driven gear in the gear train.

GearTrain was designed as a tool for educators and students wishing to learn or check calculations for a gear chain in a Technology Education or Robotics program.
