Worm gears are similar to screw in that they have teeth in 360° profile. They typically run at high RPM’s, so tolerances are held closely to ensure smooth operation, which helps reduce vibration and noise. Most are compact in size and are used as a means of reduction in speed and ratio, while increasing torque. One important characteristic of worm gears is that they create their own irreversibility, which makes them ideal for applications where single direction force or braking is needed to hold place. You can find worm gears in small electric motors, such as those found in home appliances and lawn and garden equipment, musical instruments, presses, lifts, conveyor systems, and saws.
