chain-coupling

Rigid couplings are a type of coupling that should only be utilized when shafts are precisely in line. A rigid coupling is only suitable for shafts in close alignment or held in alignment. If not aligned, torque will transfer to the shafts and bearings and likely cause premature failure. Unlike most other types of couplings, there is no flexible element in a rigid coupling.

A jaw coupling is a type of coupling designed to transmit torque while damping system vibrations, which protects other components from damage. Jaw couplings are considered the most popular couplings utilized in industry for relatively small shaft sizes.

One of the components that go into a roller chain coupling is the chain itself. The roller chains we supply are manufactured using components that have been heat-treated, shot peened, and hardened for maximum strength and durability. Typically, a coupling chain is a double-row roller chain that is ANSI size #40 – #120, then supplied as a certain pitch length based upon how large of a coupling you need. The chart below shows the standard stock sizes of coupling chains, but additional sizes are available upon request.

Rotating shaft-driven mechanical components are commonly used in all forms of machinery that perform the various processes and functions of modern industry.

• Shaft misalignment will place stresses on shafts and related parts of the assembly such as bearings, which can result in early failure of both.
• Shaft ends can be misaligned radially or angularly, exhibit axial displacement, or experience a combination of all three.
• Drive couplings can be used to compensate for shaft misalignment, whether the misalignment is an intentional or an unintentional part of the design.
