A jaw coupling is a kind of general purpose power transmission coupling that also can be used in movement control (servo) applications. It is designed to transmit torque (by linking two shafts) while damping system vibrations and accommodating misalignment, which protects other parts from damage.
Jaw Couplings are among the first and still hottest elastomer couplings in the globe because of their inherent simplicity. Two identical hubs with 3 encounter lugs are connected through a star shaped element, sometimes known as an put in or spider. The 3 piece design makes them easy to work with and popular on applications such as for example pumps, fans, blowers and compressors.
Jaw Couplings need no lubrication and offer high dependability for light to moderate duty applications with great alignment of equipment no requirement for torsional dampening.
In normal operating conditions there is absolutely no metal to metal contact therefore the life of the hubs is virtually indefinite. Nevertheless, in a catastrophic failing of the component the load would be carried by the hubs offering a degree of failure security. Jaw couplings are resistant to oil, dirt, moisture and grease.
Specific element materials are available to achieve optimum performance for the functioning conditions.
The standard element materials is NBR (N)-‘Synthetic Rubber’. It really is highly flexible, essential oil resistant and the torsionally softest of the element options. It includes a temperature 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 priced option.
