Two-part design with brake disk - Brake disk made of nodular graphite iron The Coupling RINGFEDER® TNM ETW is an torsionally flexible and shock-proof claw coupling with brake disc. They compensate for angular as well as radial and axial shaft misalignment within fixed tolerances. The torque is transmitted through an elastic transitional ring. The elastic transitional ring made of synthetic rubber (Pb) dampens shocks and torsional vibrations, is oil-resistant, insensitive to temperature and normally electrically conductive. This prevents undesirable static charging, among other things. The coupling can be used for either direction of rotation and be installed in any 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.
