The major advantage of worm gears is their capacity to provide high reduction ratios and correspondingly higher torque multipliers. They can also be utilised as reducers for reduced to medium pace applications. Also, simply because their reduction ratio is primarily based on the variety of teeth on the gear, they are more compact than other sorts of gears. Like fine pitch leadscrews, worm gears are generally self-locking, creating them excellent for hoisting and hoisting purposes.
