A coupling connects two shafts to transmit torque and rotational motion while accommodating misalignment between them. It also helps reduce vibration and protect equipment from shock loads.
Couplings can accommodate angular, parallel, and axial misalignment. The capacity depends on the coupling type and size, with typical parallel misalignment ranges of 0.1–2.0 mm and angular ranges of 0.5–3.0° per flex element.
Common materials include steel, cast iron, aluminum alloy, and polymer/elastomer. Specific grades such as 45# steel, 304 stainless steel, and AL6061 are used depending on strength and environmental requirements.
Selection should be based on application torque, service factor, bore sizes, speed, misalignment requirements, operating temperature, and torsional stiffness. Always verify model-specific values and standards with the legal manufacturer or supplier.
