How Screw Jacks Work? Main components of screw jacks are trapezoidal lifting screw, worm screw, worm gear and gear housing. Worm screw is rotated manually or by motor. Worm gear is rotated by worm screw. The lifting screw moves through the rotating worm gear. The linear motion speed of lifting screw depends on thread size and rotation ratio of worm gears.
Worm gear screw jack or worm screw jack is a mechanical motion control device used for lifting heavy weight objects, push or pull an object. The key components of screw jacks are trapezoidal lifting screw, worm screw, worm gear and gear housing. Worm screw is rotated manually (manual screw jack) or by a motor (electric screw jack).
