Jaw Coupling/rotex Coupling/flexible Coupling

This is Jaw coupling/rotex coupling/flexible coupling.Bore available from 6~180mm,torque range:12.5N.M~28000N.m.

Jaw coupling:

Jaw coupling is a type of motion control(servo)coupling designed to transmit torque(by connecting shafts)while damping system vibrations, which protects other components from damage .Jaw couplings are composed of three parts :two metallic hubs and an elastomeric insert ,which is referred as a spider. The three parts press fit together with a jaw from each hub fitted alternately with the lobes of the spider. The curved jaws of the hubs reduce deformation of the spider to maintain the zero backlash fit.

The elastomeric of the spider can be made in different hardnesss, which allows the user to customize the coupling so that it absorbs more or less vibration. The more damping ability the coupling has. The less torsion strength it possesses. Jaw coupling are best suited for applications that rely on a stop and go type of movement, where accuracy needs to take place upon stopping in order to perform any number of precision tasks ,such as taking a high resolution picture(machine vision system).Absorbing vibrations decreases the settling time the system needs ,which increases through-put .The jaw coupling is less suited for applications that rely on a constant scanning type of motion,where accuracy is required during movement ,which requires a to signally stronger coupling.

The drawback of the jaw coupling is the lack of misalignment capability .Too much axial motion will cause the coupling to come apart ,while too much angular or parallel misalignment will result in bearing loads that are higher than most other servo/motion control couplings.Jaw couplings are also considered failsafe. If the spider fails , the jaw of the two hubs will mate , much like teeth on two gears , and continue to transmit torque .This may or may not be desirable to the user depending on the application.
