Elastomer Jaw Coupling TNS S-St The RINGFEDER® TNS S-St coupling is a torsionally flexible, fail-safe 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) or polyurethane (Vk), as a standard 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. Characteristics RINGFEDER® TNS S-St Elastic claw coupling with standard single hubs. The intermediate ring can be replaced after shifting a shaft with fitted hub. Notes Standard material for intermediate ring: VkR Installed size L must be maintained without fail. Axial displacement e.g. by thermal expansions of the connected shafts, must be taken into account through allowances for value L. General features Torsionally flexible, compensate for angular, radial and axial shaft offset Intermediate rings loaded in compression Elastomers available in various shore hardness degrees Suitable for temperatures from –30°C to +100°C Outer diameter up to 400 mm Bores up to max. 160 mm Torques up to TKn = 13,350 Nm / TKmax = 40,000 Nm Speeds up to nmax = 15,000 rpm 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.
