Jaw Coupling

A jaw coupling is a kind of general purpose power transmission coupling that also can be used in motion control (servo) applications. It really is made to transmit torque (by connecting two shafts) while damping program vibrations and accommodating misalignment, which protects other elements from damage.
Jaw Couplings are one of the first and even now most widely used elastomer couplings in the globe due to their inherent simplicity. Two similar hubs with 3 face lugs are connected through a star 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 reliability for light to moderate duty applications with good alignment of equipment no requirement for torsional dampening.

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

Specific element materials are available to achieve maximum performance for the working conditions.

The standard element materials is NBR (N)-‘Synthetic Rubber’. It really 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 allows for up to at least one 1 degree misalignment capability of the connected shafts. NBR is the most economically costed option.
