The major benefit of worm gears is their capacity to provide substantial reduction ratios and correspondingly higher torque multipliers. They can also be used as reducers for reduced to medium pace programs. 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 good pitch leadscrews, worm gears are normally self-locking, producing them ideal for hoisting and hoisting purposes.
