Worm gears are used when large gear reductions are needed. It is common for worm gears to possess reductions of 20:1, and actually up to 300:1 or greater.
Many worm gears have an interesting property that no other gear set has: the worm can certainly turn the gear, but the gear cannot turn the worm. That is because the angle on the worm is indeed shallow that when the apparatus tries to spin it, the friction between your gear and the worm retains the worm set up.
This feature pays to for machines such as for example conveyor systems, where the locking feature can become a brake for the conveyor when the motor is not turning. An added very interesting usage of worm gears can be in the Torsen differential, which is utilized on some high-performance vehicles.
