Jaw Coupling

A jaw coupling is a kind of general purpose power transmission coupling that also can be utilized in movement control (servo) applications. It is made to transmit torque (by linking two shafts) while damping program vibrations and accommodating misalignment, which protects other components from damage.
Jaw Couplings are among the first and even now hottest elastomer couplings in the world because of their inherent simplicity. Two identical hubs with 3 encounter lugs are linked through a celebrity shaped element, sometimes known as an place or spider. The 3 piece style makes them simple to work with and well-known on applications such as for example pumps, enthusiasts, blowers and compressors.

Jaw Couplings require no lubrication and provide high dependability for light to medium duty applications with good alignment of equipment and no requirement of torsional dampening.

In regular operating conditions there is absolutely no metal to metallic contact so the life of the hubs is virtually indefinite. Nevertheless, in a catastrophic failure of the element the load would be carried by the hubs providing a amount of failure security. Jaw couplings are resistant to oil, dirt, dampness and grease.

Specific element materials can be found to achieve optimum performance for the working 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 industrial applications and allows for up to at least one 1 degree misalignment capability of the connected shafts. NBR is the most economically costed option.
