Gears, Velocity Ratios and Mechanical Advantage
www.northernhighlands.orgIf you want to create a high gear ratio, nothing beats theworm gear. In a worm gear, a threaded shaft engages the teeth on a gear. Each time the shaft spins one revolution, the gear moves one tooth forward. If the gear has 40 teeth, you have a 40:1 gear ratio in a very small package • Wormgearsare used when large gear reductions are needed.
