A worm gear and worm are mechanical components used to transmit motion and power between intersecting shafts.
The worm is similar to a screw, while the worm gear resembles a helical cylindrical gear.
They achieve transmission through the meshing of helical teeth, and usually the worm is the driving component.
It is widely used in the feed mechanisms of machine tools, the deceleration devices of elevators,
the steering systems of automobiles, and the lifting mechanisms of lifting equipment, achieving precise speed control and force transmission.
