What is the primary function of couplings in mechanical systems?

The primary function of couplings in mechanical systems is to connect shafts and transmit power. Couplings serve as a critical interface between two rotating shafts, allowing them to rotate together while enabling the transfer of torque and energy from one shaft to another. This connection is essential for the efficient operation of machinery, as it ensures that power generated by a motor or engine is effectively transmitted to other components of the system.

In addition to transmitting power, couplings can also accommodate some misalignment between the shafts, which can help prevent damage to the equipment. They come in various designs, including rigid, flexible, and compensating types, each serving specific applications and requirements. By maintaining this connection and facilitating the transfer of energy, couplings play a vital role in the overall functionality and reliability of mechanical systems.
