Working Principle of Worm Gearbox

The Worm Gearbox operates on a basic principle of power transmission through the interaction of a worm gear and a worm shaft. The worm gear has a helical thread, while the worm shaft has a cylindrical shape with a helical groove. When the worm shaft rotates, it engages with the worm gear, causing the gear to rotate. This rotation results in a speed reduction between the input and output shafts, allowing for precise control of rotational speed and torque.
