Flange Couplings: Essential Features, Industrial Applications and the TNF 5571 Model

​Flange Couplings are typical couplings applied to most fields of mechanical engineering, with the ability to reliably transmit torque. In particular, TNF 5571 Couplings is an essential outstanding component of the TNF series thanks to its outstanding performance. The following article will delve into the concept and application of Flange Couplings.

1. What are Flange Couplings?

The Flange Coupling is a mechanical device with a compact design, extremely strong, easy to install and maintain. Flange couplings are used to install a gapless connection between two shafts using the friction locking method. For assembly, the flange halves are attached to each shaft, then connected by screws, without the need for additional components such as: keyways or wedges as well as internal heating or external cooling.

2. Superior Features of Flange Couplings

Flange Couplings with many outstanding features, suitable for many key industries. The features can be mentioned as:

- There is no need to use additional components such as keyways or wedges or heat the inside or cool the outside, making the installation process easy.

- Has torsional stiffness and is characterized by high concentricity as well as the ability to accept large shaft tolerances, helping to transmit torque effectively and prevent wear during operation.

- In addition to the highest torque, they also transmit bending loads as well as axial and radial forces without wear and have high precision, ensuring machine performance.

3. Diverse Applications of Flange Couplings in Industrial Sectors

Thanks to the above superior features, Flange Couplings are trusted by engineers and widely used in industries such as:

- Steel Industry: In the field of steel production, components are required to withstand harsh conditions to ensure high performance and stability to maintain continuous processes such as steel rolling mills, steel coils, and melting furnaces. Ringfeder TNF is a coupling that fully meets such strict requirements.

- Cement Industry: In the field of cement production, from resource exploitation to cooling, grinding, mixing, homogenizing and storing the final product, including machinery such as stone crushers, rotary kilns, mixers ... require a solution aimed at applications with high mechanical stress and performance. Ringfeder Germany's couplings are always manufactured to meet the highest standards, especially the Ringfeder TNF series.

- Mining Industry: Similar to the steel industry, the mining industry also requires a product that can withstand harsh working environments: excavators, impact crushers, tunnelling and clearing machines and material handling systems as well as their components must meet enormous demands on their performance and reliability. That is why Ringfeder developed and launched the Ringfeder TNF coupling.

- Crane & Hoists: Loading, transporting, lifting, moving, Ringfeder Flange Couplings TNF play a decisive role in ensuring reliable and trouble-free operation of winches and cranes – whether we are talking about seaports and airports, large transit facilities or logistics centers.

- Oil & Gas Industry: Ringfeder TNF not only masters the harsh operating conditions in the harsh environments of the oil and gas industry, but also complies with current regulations and industrial standards, such as ATEX or special plant standards - to bring maximum benefits to the user in terms of reliability, functionality and safety.

- Refining Industry: Flange Couplings are ideal for use in the drives of pumps, compressors and other machinery in the field of refining technology.

- Material Handling: Achieving an uninterrupted flow of materials and goods is a priority in today's industries. Ringfeder TNF is the right coupling for use in handling and assembly units as well as conveyors and roller conveyors.

4. TNF 5571 Flange Coupling - A Standout Product from the TNF Series

Flange Couplings TNF 5571 are Backlash-Free, Frictional Shaft-Shaft Connection with Maximum Concentricity:

- Backlash-Free Operation: Increases the ability to transmit torque when operating without play, ensuring the accuracy of the machinery system.

- Frictional Shaft-Shaft Connection: To ensure the connection meets the safety standards, Ringfeder created the Frictional Shaft-Shaft Connection with surrounding screws.

- Maximum Concentricity: Ensures smooth, uninterrupted operation of the machinery, contributing to prolonging the life of the engine.

The Ringfeder TNF 5571 transmits force directly between the shaft and the flange, has a strong connection with high strength reserve. Specifications include: shaft diameters from 70 - 540 mm, with a maximum torque of up to 2,000,000 Nm, suitable for a wide range of applications.

The Ringfeder TNF 5571 flange coupling is available in two different versions depending on the respective requirements:

- Version A – Heat shrink disc with hexagon socket screw (HM = External centering; HF = Internal centering).

- Version B – Heat shrink disc with hexagon socket screw (HM = External centering; HF = Internal centering).
