Worm gear reducers, as power transmission and equipment, are widely used in industrial production and mining sectors. The transmission mechanism involves the movement between two internally misaligned shafts, with a structure and shape similar to that of a screw, including gears and other components.

Helical gear and worm drives offer their unique advantages, expanding their wide range of applications. With longer shaft spacing and transmission power, they provide a more compact fit than the inner misaligned shaft structure, and have a lower power consumption ratio in the internal misaligned shaft transmission.

The worm and worm gear reducer operates with a point contact between the two gear faces, providing a superior meshing effect compared to the internal helical gears with misaligned axes, and boasts stronger load-bearing capacity.

The worm and gear reducer is a spiral transmission, primarily utilizing tooth engagement for power transmission. It boasts advantages such as smooth operation, low energy consumption, and low noise.

Its main advantages also include strong self-locking capability. In the event of a malfunction or when the internal shaft angle exceeds 120 degrees, the built-in protective device activates the reverse self-locking feature. At this point, the only driving method available is the worm gear driven by the worm, thereby protecting the machinery and equipment.

This concludes the introduction to the working principle of worm gear screw jack reducers.
