A coupling component is a mechanical device used to connect two shafts together, allowing them to transmit power and motion. It helps in aligning the shafts and compensating for any misalignment, ensuring smooth operation in machinery. Couplings can be rigid or flexible, depending on the application and the degree of movement required. In various industries, such as automotive and manufacturing, coupling components play a crucial role in the performance of machines. They are often made from materials like metal or plastic and come in different designs, including gear couplings, disc couplings, and jaw couplings, each suited for specific tasks.
