Worm gears are used when large equipment reductions are needed. It is common for worm gears to have got reductions of 20:1, and also up to 300:1 or greater.
Many worm gears have an interesting property that no additional gear arranged has: the worm can easily turn the gear, however the gear cannot turn the worm. That is because the angle on the worm is so shallow that when the apparatus attempts to spin it, the friction between your equipment and the worm holds the worm in place.
This feature is useful for machines such as for example conveyor systems, where the locking feature can become a brake for the conveyor when the motor isn’t turning. An added very interesting usage of worm gears is definitely in the Torsen differential, which is utilized on some worm gear high-performance cars and trucks.
