Purpose of worm gears
WebWorms and worm gears are gear sets that offer high gear reduction and torque multiplication with a small footprint. A worm drive is a cylindrical gear with a shallow spiral thread that engages the worm gear in a non-intersecting, perpendicular axes configuration. Efficiency of a worm drive is determined by the lead angle and the number of ... WebNov 20, 2000 · 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, such as in a windshield wiper. A mechanical odometer is another place that uses a lot of worm gears.
