Coupling components are mechanical devices used to connect two shafts together, allowing them to transmit power and motion. They help ensure that the shafts rotate in sync, which is essential in various machinery and equipment. Common types of coupling components include rigid couplings, flexible couplings, and universal joints, each serving different applications based on the required flexibility and alignment. These components play a crucial role in reducing wear and tear on machinery by accommodating misalignment and absorbing shock loads. Proper selection of coupling components can enhance the efficiency and lifespan of systems in industries such as automotive, manufacturing, and aerospace.
