2. Characteristics of Flexible Couplings TNM ETW1/ETW2
– Manufacturer brand: Ringfeder/Germany.
– Torque [Nm]: 20,500 to 49,000
– Speed [rpm]: 4,580
– Temperature range: -30°C to +100°C
– Maximum bore diameter: up to 190 mm
– Two-part design with equal halves.
– Flexible torsion, compensating for angular, radial, and axial misalignment.
– Intermediate rings are loaded during compression.
– The shaft coupling features a two-part design with cast iron brake discs. Damping rings with different stiffness levels: standard Pb72, hard Pb82. Torque is transmitted through a damping ring. It can rotate flexibly in all directions and compensate for angular, parallel, and axial misalignments of connected machines. Suitable for both directions of rotation and can be installed in any position.
– Thanks to the rotational recovery capability of Ringfeder TNM ETW1/ETW2 Coupling, dangerous torsional oscillations from the operating threshold are transferred to the speed threshold without any negative effects. The damping rings are capable of damping with high-quality materials, helping to improve coupling resonance within limits when passing through dangerous speed thresholds, thereby protecting connected machines from damage.
