Most flexible couplings consist of 2 hubs and 1 middle assembly; each hub attaches to a shaft while the middle assembly flexes between the hubs to accommodate the misalignment of the 2 shafts. Shaft misalignments are generally either parallel or angular and cause complications to transmitting rotational power from 1 shaft to another in the form of stresses, loads, vibrations, and other forces, which vary from 1 type of misalignment to another. Flexible couplings are used in a broad range of applications, such as conveyors, escalators, agricultural, forestry, mining equipment.
