The major edge of worm gears is their potential to provide large reduction ratios and correspondingly substantial torque multipliers. They can also be utilized as reducers for minimal to medium speed purposes. Also, because their reduction ratio is dependent on the variety of teeth on the equipment, they are much more compact than other kinds of gears. Like fine pitch leadscrews, worm gears are normally self-locking, producing them best for hoisting and hoisting apps.
