Exploring mechanical transmission methods and their application examples

Worm gear mechanism, as one of the top ten mechanical transmission methods, is mainly used to transmit motion and power between two intersecting shafts. Its uniqueness lies in its smooth and noise free transmission characteristics. This is due to the continuous and uninterrupted spiral design of the worm gear teeth, which ensures that the meshing with the worm gear teeth is always continuous, eliminating the process of the worm gear teeth entering and exiting the meshing, thereby ensuring a smooth working state and reducing impact, vibration, and noise.

The worm gear mechanism not only has a smooth and noise free transmission characteristic, but also can achieve a large transmission ratio, similar to a gear reduction device, and has self-locking function. Therefore, it is widely used in daily life, such as driving escalators, elevators, moving sidewalks, and in recent years, it can be seen in machines designed for environmental protection to prevent pollution.
