A worm screw and a worm gear make up a worm gearbox, a sort of mechanical power transfer mechanism. The worm gear resembles a toothed wheel with a helical form, whereas the worm screw resembles a threaded rod. The worm gearbox's high gear ratio, which it can give because to the screw and gear's contact, makes it the perfect choice for applications requiring significant speed reduction and torque multiplication. It is frequently utilised in machinery and apparatus where precise and controlled motion is required, such as in conveyors, industrial machinery, and steering systems in automobiles.
