Couplings are essential mechanical components widely adopted in various mechanical transmission systems, serving the core function of connecting driving and driven shafts to transmit torque and rotational power stably. Beyond basic power transmission, they deliver multiple practical performances that optimize mechanical operation. They can effectively compensate for minor shaft misalignment caused by assembly errors, thermal expansion or mechanical wear during equipment operation. Additionally, couplings absorb vibration and buffer impact forces generated in high-speed or intermittent operation, reducing mechanical friction and component wear. They also act as a protective barrier, preventing overload damage to core equipment when sudden load fluctuations occur. These versatile functions make them indispensable in industrial automation, power generation, mechanical manufacturing and fluid transportation facilities, ensuring long-term stable, efficient and safe operation of all kinds of rotating machinery.
