Introduction to the characteristics of the Ringfeder torsional elastic coupling TNB BH
Founded in 1922, Ringfeder Power Transmission provides high-quality transmission solutions for a wide range of industries. For more than 36 years, they have been industry researchers in the field of keyless shaft hub technology. In addition, they offer shock absorbers, couplings, torque limiters, and other special and customized products. These components are used in mechanical applications in a variety of industries, such as metalworking, oil & gas, and machine tools.
Elastomer jaw coupling TNB BH
Elastomer jaw coupling TNB:
Torsional elastic couplings are puncture-resistant and flexible in all directions, so they effectively compensate for axial, transverse and angular axis misalignment caused by inaccurate assembly or settlement. Excellent robustness and damping properties guarantee maximum operational reliability for the user, especially in applications with significant shock, alternating or vibration loads. Depending on the customer's specific requirements, e.g. regarding the intended use, environmental conditions or torque transmission, we offer the most suitable coupling solution.
The Ringfeder TNB BH coupling is a torsionally flexible, puncture-resistant jaw coupling. It compensates for angular, radial and axial misalignment within a defined range. The coupling transmits torque through a compression-loaded elastic buffer. These shock absorbers are available in synthetic rubber (PB) or polyurethane (VK) as standard VKW. These elastomeric shock absorbers suppress shock and torsional vibrations and are oil resistant. The coupling is suitable for every direction of rotation and mounting position. ®
General features of the Ringfeder TNB BH coupling:
Torsional flexibility to compensate for angular, radial and axial misalignment.
Compress the loaded buffer.
The buffer can be changed radially without the need to move the coupled machine.
Elastomers come in a variety of shore hardnesses.
Suitable for temperatures from 30°C to +100°C.
Outer diameters up to 900 mm
The maximum bore diameter is up to 360 mm
Torque up to t Ken = 260,000 Nm t of kmax = 780,000 nautical miles.
Speeds up to nMax = 4,100 rpm.
Puncture-resistant and torsional flexible couplings effectively compensate for axial, radial and angular shaft misalignment and are proven to be extremely robust even under the harshest environmental conditions, such as extreme temperatures or severe dirt and dust generation. As a result, they are preferred for use in steel mills, rolling mills and cement plants, mining and construction machinery such as bucket wheel excavators, shredder facilities and tunnel boring machines, as well as in offshore technology. The torque is transmitted via a pressure-resistant oil-resistant elastomer buffer made of high-quality butylene glycol or polyurethane, which also absorbs process-related shocks and buffers the dynamic effects caused by the acceleration of heavy objects. As a result, dangerous torsional vibrations from the mechanical operating range of the plant are diverted to a speed range that does not have a negative effect. The Ringfeder TNB heavy-duty couplings can be used in any direction of rotation and mounting position, and thanks to their modular design, users can use a wide range of standard and special models.
