The principal benefit of worm gears is their ability to provide substantial reduction ratios and correspondingly high torque multipliers. They can also be utilized as reducers for reduced to medium velocity apps. Also, since their reduction ratio is based on the variety of teeth on the equipment, they are much more compact than other sorts of gears. Like good pitch leadscrews, worm gears are typically self-locking, creating them perfect for hoisting and hoisting programs.
