Worm drive Wikipedia

A worm drive is a gear arrangement in which a worm (which is a gear in the form of a screw) meshes with a worm gear (which is similar in appearance to a spur gear).The two elements are also called the worm screw and worm wheel.The terminology is often confused by imprecise use of the term worm gear to refer to the worm, the worm gear, or the worm drive as a unit.

Machine Screw Jacks Joyce

Where are worm gear machine screw jacks used? Worm gear machine screw jacks are the workhorses of the lifting industry, available in static capacities up to 250-tons. They are commonly used to lift, hold, and position loads. Examples include: Platform lifts, Damper adjustments, Ergonomic lifts, Maintenance lifts, Roll adjustments, Earth Station

Worm Gears McMaster-Carr

Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle. They transmit motion from worm to gear and cannot be reversed. For gears and worms to mesh correctly, they must have the same pressure angle and pitch/module. These worms are compatible with plastic worm gears.. Speed ratio is the ratio by which output shaft speed is reduced.

Ball Screw Jacks Joyce

Ball screw jacks include ball nuts that are about 90% efficient so the jacks require much less energy to lift an equal load than their machine screw jack counterpart. They are NOT self-locking so a brake motor needs to be included in the drive system and hand wheels are not a recommended option.
