Coupling refers to a device used to connect two rotating shafts. These shafts may be the drive shaft of a motor and the driven shaft of a machine, or two sections of a line shaft. Couplings are used to transmit torque from one shaft to another. There are various types of couplings, each suited for different applications. Some common types include rigid couplings, which are used when precise alignment between shafts is possible and shock or vibration is minimal. Flexible couplings, on the other hand, are designed to accommodate misalignment between shafts, as well as to dampen vibrations and absorb shock. Examples of flexible couplings include jaw couplings, which consist of two hubs with jaws that interlock with an elastomeric element, and gear couplings, which use meshing gear teeth. Other types, like fluid couplings, utilize a fluid medium to transmit power, allowing for smooth starts and overload protection. Magnetic couplings use magnetic fields to transmit torque without physical contact, offering sealing benefits. The selection of a coupling depends on factors such as the torque to be transmitted, the speed of rotation, the degree of misalignment, environmental conditions, and the need for vibration damping. Proper selection and installation are crucial for the efficient and reliable operation of rotating machinery.
