Säkerhetskoppling

Säkerhetskoppling is a Swedish term that translates to "safety coupling" or "safety clutch" in English. It refers to a mechanical device designed to protect machinery from damage due to overload or jamming. When the torque transmitted through the coupling exceeds a predetermined limit, the safety coupling disengages, breaking the power transmission between the driving and driven components. This prevents catastrophic failure of the equipment, such as broken shafts, damaged gears, or motor burnout.

There are various types of säkerhetskoppling, each operating on different principles. Some common mechanisms include shear pins, which break under excessive load, and slip clutches, which allow relative motion between the input and output shafts when the torque limit is reached. Resetting a safety coupling after activation can range from simple manual replacement of a shear pin to automatic resetting mechanisms in slip clutches. The choice of safety coupling depends on the specific application, the type of machinery, and the expected overload conditions. Proper selection and maintenance of a säkerhetskoppling are crucial for ensuring the reliability and longevity of industrial equipment.
