Key Characteristics of the Elastomer Rings TNB
The elastic RINGFEDER® TNB buffers are crafted from butadiene-nitril-rubber (Pb82) or polyurethane (VkR, VkW). The black buffer (Pb82) is typically electrically conductive, preventing undesirable electrostatic charges. Conversely, the red (VkR) and white (VkW) buffers provide electrical insulation between connected machines, provided there are no other electrically conductive connections.
- The resilience of each elastomer material is indicated by its Shore hardness, which can indirectly determine the torque the coupling can transmit and its spring stiffness. For more details, please refer to the technical data sheet.
- Elastomer Rings TNB are manufactured by Ringfeder/Germany. It also known as "vòng đệm giảm chấn TNB".
- Elastomer Rings TNB have a high material damping capacity which enables the rings to keep resonance enhancements within limits when passing through dangerous speed ranges, thus protecting the coupled machines from damage.
The Elastomer Rings also reduce torque and cause the system to stop very quickly when excited by an impact due to the damping qualities of the material. The structure of the rubber is responsible for the reduction of noise when transmitting.
