2. Characteristics of Flexible Couplings TNB BHD BS:
– Flexible Couplings TNB BHD BS are manufacturer by Ringfeder/Germany.
– Twist flexibility, compensating for angular, radial, and axial misalignments.
– Buffer is loaded in compression.
– Buffers can be replaced radially without the need to move the connected machines.
– Resilient material available in various hardness levels.
– Suitable for temperatures from -30°C to +100°C.
– Outer diameter up to 900 mm.
– Maximum bore diameter: 400 mm.
– Torque up to TKn = 260,000 Nm / TKmax = 780,000 Nm.
– Speed up to nmax = 4,100 rpm.
– The coupling is designed in three parts with brake disc and VkR buffer.
– Due to the coupling’s rotational recovery ability, dangerous torsional vibrations from the operating range of the plant machinery can be transferred to the speed range without any negative effects.
– The resilient buffers are capable of cushioning with high-quality materials, allowing the couplings to maintain improvements within limits when passing through dangerous speed ranges, thus protecting the connected machines from damage.
– The Ringfeder TNB BHD-BS couplings also minimize torque shocks and quickly dampen a vibration system excited by an impact due to the material’s damping quality. Noise transmission is prevented by the structure.**
– The buffers of the Ringfeder TNB BHD-BS couplings are made of butadiene-nitrile rubber (Pb82) or polyurethane (VkR, VkW). The black buffers (Pb82) are typically conductive, thus preventing unwanted static electric charges. The red (VkR) and white (VkW) buffers ensure insulation between the connected machines as long as there are no other conductive connections. The recovery ability of each resilient material is determined by its Shore hardness. From these values, an indirect conclusion can be drawn about the torques the coupling can transmit and its spring stiffness.
