Coupling

**Working Principle** Fixed at the ends of the driving and driven shafts respectively, they rely on their own structural interlocking or elastic fit to rotate synchronously, smoothly transmitting torque from one shaft to the other. Elastic material types can compensate for installation misalignment and operational vibration, while rigid types achieve precise synchronous transmission. **Application Fields** 1. Electromechanical matching: Power connection between industrial motors and pumps, fans, and air compressors 2. Power generation equipment: Precise connection and transmission between engine and generator main shafts 3. Heavy machinery: Transmission shaft connection for reducers, cranes, and mining equipment 4. Assembly line equipment: Transmission shaft connection for conveying equipment and automated machine tools
