Couplings

Couplings

Couplings are mechanical components used to connect two in-line shafts to enable one shaft to drive another at the same speed. A coupling can be rigid or flexible, allowing various amount of angular, radial, and axial misalignment between the two shafts. Couplings can be used to reduce shock and overload, which can decrease wear on the machine and increase overall lifetime. Unlike clutches, couplings are not designed to engage-disengage as a normal operation.
