Elastomer Jaw Couplings TNS SX | RINGFEDER®

The RINGFEDER® TNS SX coupling is a torsionally flexible, fail-safe claw coupling which is particularly suited for use with hydrodynamic couplings. 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) or polyurethane (VkR)and are connected to each other to form an elastic intermediate ring. The elastic intermediate ring can cushion impacts and torsional vibrations; it is oil-resistant. Intermediate rings made of Perbunan are electrically conductive.

INTRODUCTION

The rotationally resilient coupling of the RINGFEDER® TNS coupling 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.

Elastic intermediate ring

With the RINGFEDER®-TNS coupling, the torque is transmitted via a compressed elastic intermediate ring. The elastic intermediate ring absorbs shocks and torsional vibrations, is resistant to oil and largely insensitive to temperature.
The strength of different elastomer materials is indicated by their Shore hardness. Elastomers of different strengths are colour-coded for identification. Further details concerning the strength and load capacity are available on request in the technical data sheet.

Elastomer Materials

The elastic intermediate rings of RINGFEDER® TNS are made of butadiene-nitril-rubber (Pb82) or polyurethane (VkR). The black buffer (Pb82) are normally electrically conductive and therefore prevent undesirable electrostatic charges. The red (VkR) ring ensure electrical insulation between connected machines as long as there are no other electrically conductive connections. The resilience of the individual elastomer materials is designated by their Shore hardness. From these values an indirect conclusion can be drawn with respect to the torques the coupling is able to transmit and its spring stiffness. For further details, please see the technical data sheet.

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.

Environmental conditions

The employed elastomer materials operate reliably in ambient temperature ranges of –30° to +100°C. Please contact RINGFEDER POWER TRANSMISSION if higher ambient temperatures are involved. The influence of the temperature on the coupling size selection is explained in more detail in the below-mentioned design directives. It is only allowed to operate the coupling 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. The coupling can be declared compliant with the European Directive 2014/34/EU (ATEX). Please contact RINGFEDER POWER TRANSMISSION regarding the declaration of conformity according to 2014/34/EU and the effects of aggressive ambient media.
