Couplings transmit power from one shaft to another. The input shaft connects to the power source. The output shaft connects to the destination. There are two primary types of couplings.
Rigid couplings align the shafts with each other. Perfect alignment reduces wear on the machine. Rigid couplings maximize performance and efficiency. Sleeve-style couplings are the most common rigid couplings.
Sometimes the shafts do not meet perfectly. Flexible couplings transmit power without perfect alignment. Beam couplings are cut in a spiral shape. These can accommodate several degrees of shaft offset. Flexible couplings help reduce noise and unwanted vibrations.
