Elastomer coupling TNM G

Three-part design, elastic ring can be replaced without having to axially move the machine The coupling RINGFEDER® TNM G 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. A coupling half is divided in two and allows through this a simple separation of the coupled machine. With the claw ring pulled back it is possible to check the rotational direction of the drive. It is also possible to lift out radially a coupling half with accompanying aggregate. The elastic intermediate ring can be changed without axially shifting the machine. 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.
