3. Functions of Flexible Couplings TNB BH
Elastomer Jaw Couplings TNB BH is prioritized for use in steel mills, steel rolling mills, cement plants, in mining operations, and construction machinery, such as excavators and tunnel drilling machines, as well as in offshore technology.
This coupling compensates for angular, radial, and axial shaft misalignment. The rubber damping rings are loaded in compression, and the rings can be replaced without having to move the connected machinery. Rubber damping rings are available in various degrees of hardness.
See article: Comparison of 5 types of mechanical shaft couplings in industry
4. Technical of Elastomer Jaw Couplings TNB BH
Elastomer Jaw Couplings TNB BH transmits torque through resilient rubber damping rings that bear the load during compression. These damping rubbers are made of synthetic rubber (Pb) or polyurethane (Vk), such as a standard VkW. These resilient damping rings reduce shock, absorb vibrations, and torsional oscillations, with the ability to resist oil. They are suitable for use in all rotational directions and mounting positions. Replacement of the damping rubber rings is easy without the need to move the connected machinery along the shaft axis. The resilient materials used operate reliably within a temperature range of approximately -30°C to +100°C.
