Coupling is the most commonly used coupling component in mechanical product shafting transmission. It is mainly used to connect two shafts to rotate together to transmit torque and motion, compensate the relative displacement of the two shafts and improve the transmission dynamics of the system. It is a major technical equipment. The basic components are widely used in metallurgy, mining, lifting, engineering machinery, automotive, paper, textile, non-ferrous, shipbuilding and other industries.
Couplings for steel are both core components and consumables. Cross-shaft universal couplings and drum-shaped couplings are mainly used for hot-rolled strip steel, medium-thick plate steel, cold rolling in the steel industry. Production lines such as strip steel, long steel, and pipe steel are the core components of the rolling and forging equipment; at the same time, the coupling is also a wearing part, which is usually replaced once a year.
