Function of torsionally flexible jaw couplings:
Jaw couplings ensure torsional vibration-damping power transmission absorbing shocks generated by irregularly operating machines. In contrast to flexible couplings the connecting elements of which are subjected to bending and therefore to earlier wear, the flexible teeth of ROTEX® couplings (elastomers) are subjected to compressive stress only. The benefit of the elastomer coupling thus is to withstand significantly higher loads.
The elastomers deform with load and high speeds. Sufficient expansion space must be provided.
All sizes of ROTEX jaw couplings have a maximum torsion angle of 5°. They can be mounted both horizontally and vertically.
