The rotationally resilient couplings of the RINGFEDER series GWE, TNM, TNS, and TNB are puncture-proof and flexible in all directions and therefore compensate for angular, parallel, and axial shaft misalignments of the connected machines. Misalignments can be caused for example by inaccurate assembly, heat movements, or settling phenomena.

Avoiding torsional vibration
By virtue of the rotational resilience of the coupling, dangerous torsional vibrations from the operational range of plant machinery can be transferred to rotational speed ranges in which no negative effects are to be expected. Material damping of the elastic parts contributes to limiting the resonance peaks when passing risky revolution ranges and thus offers the protection of coupled machines from damage. The damping of the couplings also alleviates torque shocks and has a calming effect on the activated oscillatory system The transmission of structure-bound noise is reduced.

Environmental conditions
The employed elastomer materials operate reliably in ambient temperature ranges of -30° to +100°C. Materials are available for higher and lower temperatures on request. The influence of the temperature on the coupling size selection is explained in more detail in the below-mentioned design directives. The coupling should only be operated in normal industrial air. Aggressive media may attack the coupling components, bolts, and elastic elements and therefore present a danger to the operational safety of the coupling.
