TSCHAN® TNS SDD-5

The TSCHAN® TNS SDD-5 coupling is a torsionally flexible, puncture proof claw coupling with removable intermediate part comprising the claw rings and the buffer ring. It compensates for angular, radial and axial shaft misalignments within defined limits. The coupling transmits torque through elastic buffers loaded in shear. These buffers come in Perbunan (Pb) or polyurethane (Vk), as a standard VkR, and are connected to each other to form an elastic buffer ring. This buffer ring dampens shocks and torsional vibrations and is resistant to oil. Buffer rings made of Perbunan are electrically conductive. The two-parted construction of both coupling halves allows radial mounting and dismounting of the intermediate part. The buffer ring can, therefore, be replaced without having to displace the connected machines. When the intermediate part is removed, it is easily possible to check the rotational direction of the drive. The coupling is suitable for use in every direction of rotation and installation position.

The TSCHAN®-TNS coupling is a torsionally flexible, shock-proof claw coupling. It compensates angular, radial and axial shaft misalignment within specified tolerances.

Elastic intermediate ring

With the TSCHAN®-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.

Special features

Material

Polyurethane (Vk..) intermediate rings ensure electrical insulation between connected machines as long as there are no other electrically conductive connections. Intermediate rings made of Buna N (Pb) and of grade VkB are normally electrically conductive and can therefore prevent undesirable electrostatic charges.

No torsional vibrations

The torsional elasticity of the intermediate ring allows dangerous torsional vibrations to be transferred from the operational range of the machines to speed ranges in which negative effects are not to be expected.

Reduction in torque shocks

The elastic intermediate rings have a high internal damping characteristic which limits excessive torsional vibrations on reaching dangerous speed ranges, alleviates torque shocks and rapidly eliminates the oscillation stimulated by such shocks. The propagation of structure-borne sound is prevented.

Strength

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.

Temperature

The elastomer materials used here are suitable for ambient temperatures from -30 °C to +100 °C.

Balancing

The coupling is balanced to DIN/ISO 1940, G 6.3 and DIN/ISO 8821 if required. Other qualities are available on request.
