Torque serves as the core functional parameter of couplings, defining their ability to transfer rotational force between connected rotating shafts in various mechanical systems. As a key mechanical component, couplings undertake stable torque transmission from driving ends to driven ends, ensuring consistent and efficient power output for operating equipment. Beyond basic power transfer, well-designed torque performance enables couplings to tolerate minor axial, radial and angular shaft misalignment, effectively buffering mechanical vibration and impact loads during operation. This capability avoids torque fluctuation caused by assembly errors or operational wear, stabilizing the overall mechanical operation. Reasonable torque matching is critical to system safety and durability; excessive torque burden may lead to component deformation or fatigue damage, while insufficient torque output will reduce equipment efficiency. Proper torque adaptation extends mechanical service life, lowers maintenance frequency, and guarantees reliable, long-term operation of industrial transmission systems in diverse working conditions.
