What is the purpose of coupling in power transmission?

The purpose of coupling in power transmission is to connect two shafts together. Couplings serve as a mechanical link that allows power to be transmitted from one shaft to another, which is essential in many machinery applications. By connecting shafts, couplings facilitate the transfer of torque and rotational motion, ensuring that machinery operates efficiently and effectively.

In various applications, it is important for the connected shafts to maintain alignment and accommodate for any misalignment that may occur during operation. Couplings can help absorb vibrations and shocks, thereby protecting the connected machinery from potential damage. This function is critical in maintaining the integrity of the power transmission system, allowing for smooth operation.

While increasing speed, limiting torque, or enhancing aesthetic design may be considerations in machinery design, they are not the primary objectives of coupling. The centric purpose of coupling remains focused on the mechanical connection and the transmission of power between rotating parts.
