Connectors, or "couplings," are crucial elements in the maintenance of industrial aerospace machinery, as they facilitate the transmission of power and movement between different components of the system. Their main function is to join rotating shafts, allowing them to couple efficiently without energy loss. In the aerospace field, where precision and reliability are essential, choosing the right connector is fundamental to ensuring the correct operation of aircraft.

There are different types of connectors, such as flexible, rigid, sliding, and alignment connectors, each designed to fulfill specific functions. Flexible connectors, for example, absorb misalignments and vibrations, thus protecting other components of the system. On the other hand, rigid connectors offer a firmer connection, ideal for applications that require high precision.

Regular maintenance of these elements is vital to prevent failures and ensure operational safety. Periodic inspections and performance tests allow for the identification of wear or damage that could compromise the integrity of the system.
