Nordex Featured in Power Transmission Engineering Article “Coupling Connection”
Simply defined, a coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. The coupling has been around since shortly after the invention of the wheel, i.e.—no wheel, no coupling. And something that has been around even longer than that is the often harsh and extreme environments in which couplings are at times required to function. Considering the seemingly endless list of coupling applications—from mining to the space station—it’s a given that couplings are often subjected to, among other things, extreme heat, cold, sand and degraded lubrication.
