3 Pulley, belt drive and gear ratio

Pulley ratios

  • Below is a video of how to calculate gear ratios and speed calculation.
  • The formula above applies to all drive systems. For pulleys, you would use the diameter instead of number of teeth.
  • Chain and sprocket calculations will be the same as gear calculations.
  • One thing to note, in gear drive systems, the gears will spin in opposite directions as they move through the gears.
