When a component is damaged, the entire transmission mechanism needs to be disassembled and replaced. Moreover, due to the variability and complexity of the working environment, the traditional worm gear system is easily corroded by external dust, dirt, water and moisture, causing corrosion, wear and even failure of the worm gear, thereby seriously affecting the performance and life of the equipment.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A split dual-lead worm gear pair system includes a first support body, each of which is provided with a mounting mechanism for connecting a worm gear, the mounting mechanism including:

The internal worm gear body is arranged on the second support body, and the double-lead worm body is arranged on the first support body. A modular design is adopted, so that the worm gear can be installed and disassembled relatively independently, which is convenient for system maintenance and upgrading. When a component is damaged or needs to be replaced, it can be handled separately without affecting the normal operation of other components. When a component is damaged, only the component needs to be replaced to restore the normal operation of the system without replacing the entire equipment, thereby reducing maintenance costs.
