In kaak koppeling is a kind 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 components from damage.
Jaw Couplings are one of the first and still hottest elastomer couplings in the world because of their inherent simplicity. Two similar hubs with 3 encounter lugs are linked through a superstar shaped element, sometimes referred to as an put in or spider. The 3 piece style makes them easy to work with and popular on applications such as for example pumps, enthusiasts, blowers and compressors.
Jaw Couplings need no lubrication and provide high reliability for light to moderate duty applications with great alignment of equipment and no requirement for torsional dampening.
In normal operating conditions there is no metal to metallic contact therefore the life of the hubs is practically indefinite. Nevertheless, in a catastrophic failure of the element the load would still be carried by the hubs offering a amount of failure safety. Jaw couplings are resistant to essential oil, dirt, dampness and grease.
Specific element materials can be found to achieve maximum performance for the operating conditions.
The standard element material is NBR (N)-‘Synthetic Rubber’. It really is highly flexible, essential oil resistant and the torsionally softest of the element options. It has a temp operating range ideal 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.
