Coupling performance requirements

Depending on the specific operating conditions, couplings must possess the following properties:

Mobility. The mobility of a coupling refers to its ability to compensate for the relative displacement of two rotating components. Factors such as manufacturing and installation errors between the connected components, temperature changes during operation, and deformation under load all impose requirements on mobility. Mobility compensates for or mitigates the additional loads on shafts, bearings, couplings, and other components caused by the relative displacement between rotating components.

Buffering. For applications with frequent load starts or changing operating loads, couplings must contain elastic elements that act as buffers and dampers to protect the prime mover and driven machine from damage.

Safety and reliability, with sufficient strength and service life.

Simple structure, easy to assemble, disassemble, and maintain.
