The principal gain of worm gears is their capability to provide substantial reduction ratios and correspondingly higher torque multipliers. They can also be employed as reducers for minimal to medium speed purposes. Also, due to the fact their reduction ratio is dependent on the variety of enamel on the gear, they are a lot more compact than other types of gears. Like fine pitch leadscrews, worm gears are normally self-locking, producing them excellent for hoisting and hoisting apps.
