Flexible couplings are mechanical devices used to connect two shafts while allowing for some degree of misalignment between them. They help transmit torque and rotational motion while accommodating slight variations in alignment due to manufacturing tolerances or operational conditions. This flexibility helps reduce wear and tear on connected components, enhancing the overall lifespan of machinery. These couplings come in various designs, including rubber, gear, and disc types, each suited for specific applications. They are commonly found in industries such as automotive, manufacturing, and aerospace, where reliable power transmission is essential for efficient operation.
