Chain couplings: small maintenance, more power
Chain couplings are ideal for elastic torque transmitting over a wide velocity range. They are powerful, effective and robust e. g. concerning higher temperatures and small angle or parallel displacement.
Furthermore, they are low-maintenance products, they are easy to separate by merely opening the coupling chain, and they provide an excellent price / performance ratio for numerous applications in machine and plant structure. The wide software range is because of the many coupling sizes that can be supplied.
Mounting of the particular coupling sprockets with hardened toothing is carried out inversely on the two opposite shaft extensions. Nevertheless, certain stipulated requirements as to angle deviation and parallel displacement need to be fulfilled. The coupling chain – a measured duplex roller chain according to ISO 606 – is definitely placed around the toothing of both sprockets and closed by means of a connecting link.
Chain couplings are utilized to transmit power between two shafts. Generally, chain 
couplings will be set up off the end of a electric motor or reducer (gearbox) and useful to hook up to a machine for effective power transmission. A total chain coupling contains two hubs (or sprockets), one coupling chain, which appears similar to a strand of dual roller chain and a cover. Not all applications will use a cover, but also for both safety and coupling life they are recommended. Chain couplings are usually utilized in low acceleration, high torque applications and allow for 2 degrees misalignment between shafts. Chain couplings are considered an economical method to transmit power between shafts. Please contact Bearing Service to help provide or design in the right coupling for the application.
The Ever-power chain coupling, made up of two-strand roller chains and two sprocket wheels, features simple and compact structure, and high flexibility, power transmission capability and durability.
What’s more, the chain coupling allows simple connection/disconnection of shafts one another, and the use of the housing enhances basic safety and durability.
