A jaw coupling is a mechanism used to connect two different motor shafts within a single application. It can be used as a means to connect two different systems, to repair a single system’s connection, or to reduce shock or wear between two shafts. There are two options that can be used to join a system: rigid or flexible couplings. Flexible couplings allow for some movement between the shafts, while jaw couplings are used when precise alignment and a secure connection are needed. Rigid couplings help maximize a machine’s performance by holding the shafts tightly in place, and keeping them perfectly aligned. This also extends the machine’s expected lifetime. There are two different types of Jaw Couplings: Sleeve-style couplings, or clamped jaw couplings. The cost-effective and easy to use, Sleeve-style couplings consist of a single tube, with an inner diameter that is equivalent to the shaft size. The material that makes up the sleeve slips over the two shafts so they meet at the coupling’s midpoint. Set screws can be tightened to touch the top of each shaft, in order to prevent an individual shaft from passing all the way through the coupling and ensure the two meet in the middle. The second type of jaw coupling is a Clamped, or compression jaw coupling. These couplings entail two pieces that fit around the shafts of the motor to form a sleeve. These couplings can be used on fixed shafts, and are a bit more flexible than a sleeve-style coupling. They have set screws that can pass through the entire coupling, in order to ensure a firm hold. For industrial applications with heavy loads, Flanged jaw couplings are recommended. These couplings have short sleeves surrounded by a perpendicular flange. Each flange faces each other, with a coupling on each shaft. Screws and bolts can be added to hold the two flanges together. Flanged components can align shafts before they are joined, due to their durability and size. When exact shaft alignment is needed for an application, typically a Rigid coupling is used. When a shaft is misaligned, both the coupling’s performance and lifespan are affected.
