What is one benefit of using a flexible coupling?

Using a flexible coupling provides the significant benefit of accommodating shaft misalignment. In mechanical systems, misalignment can occur due to various reasons, such as thermal expansion, vibrations, or installation errors. A flexible coupling is designed to absorb these misalignments, allowing for both angular and axial variations between connected shafts without causing stress on the components. This characteristic helps to maintain the integrity of the system, reduce wear and tear, and extend the lifespan of both the coupling and the connected machinery. By allowing some movement, flexible couplings can also help in minimizing the risk of failure that could arise from misalignment, leading to more reliable operations in mechanical systems.
