A worm reduction gearbox is a mechanical device that uses the meshing transmission of a worm and a worm wheel to achieve speed reduction. The worm is similar to a screw and has a large lead angle, while the worm wheel is a gear with a special shape. When the worm rotates, the power is transmitted to the worm wheel through the interaction between the helical tooth surface of the worm and the tooth surface of the worm wheel, thereby achieving speed reduction.
