Elastomer coupling TNM E

jawtorsionally flexibleshaft

The coupling RINGFEDER® TNM E is a torsionally elastic and puncture-proof claw coupling. It balances out angular, radial and axial shaft misalignments within defined limits. The coupling transfers the torque via pressure loadable, elastic buffers of synthetic rubber (Pb) which are joined together as an intermediate ring. The elastic intermediate ring can cushion impacts and torsional vibrations; it is oil-resistant and electrically conductive. The coupling is usable in every sense of rotation and installation position. INTRODUCTION The rotationally resilient coupling of the RINGFEDER® TNM series is flexible in all directions and therefore compensates 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. The elastic intermediate rings possess a high material damping capability which makes it possible for the couplings to keep the resonance enhancements within limits when passing through dangerous speed ranges, thereby protecting the coupled machines against damage. The couplings also mitigate torque shocks and cause a vibrating system that has been excited by an impact to come to rest very quickly due to the material damping qualities. The conduction of structure-borne noise is prevented.
