Jaw Coupling

A jaw coupling is a type of general purpose power transmission coupling that also can be used in movement control (servo) applications. It really is designed to transmit torque (by connecting two shafts) while damping system vibrations and accommodating misalignment, which protects other elements from damage.
Jaw Couplings are among the first and even now hottest elastomer couplings in the globe due to their inherent simplicity. Two similar hubs with 3 encounter lugs are connected through a celebrity shaped element, sometimes known as an put in or spider. The 3 piece style makes them easy to work with and well-known on applications such as pumps, enthusiasts, blowers and compressors.

Jaw Couplings need no lubrication and provide high dependability for light to moderate duty applications with great alignment of equipment no requirement of torsional dampening.

In regular operating conditions there is no metal to metal contact so the life of the hubs is practically indefinite. Nevertheless, in a catastrophic failing of the element the load would be carried by the hubs offering a amount of failure security. Jaw couplings are resistant to essential oil, dirt, wetness and grease.

Specific element materials are available to achieve optimum performance for the operating conditions.

The standard element material is NBR (N)-‘Synthetic Rubber’. It is highly flexible, oil resistant and the torsionally softest of the element options. It includes a heat range operating range suitable for most commercial applications and permits up to 1 1 degree misalignment capability of the linked shafts. NBR is the most economically costed option.
