#Worm-Gears-suppliers #Vidhya-Trading A worm gear is a type of gear that consists of a worm (a screw-like gear) and a worm wheel (a cylindrical gear). The worm has one or more teeth that mesh with the teeth on the worm wheel, and as the worm rotates, it drives the worm wheel to rotate as well. Worm gears are often used when a high gear reduction ratio is needed, as they can achieve ratios of 20:1 or higher. They also have the advantage of being self-locking, meaning that the worm can drive the worm wheel, but the worm wheel cannot drive the worm, making them useful in applications where safety is a concern.
