Ringfeder TNR Coupling is Used for Generators and Diesel Engines According to SAE J 620 Standards

The Ringfeder TNR coupling (Torsional Highflex Couplings TNR) is a high-quality torsional flexible coupling with a flange that meets SAE J 620 d. X1 standards. Its special features make it a preferred choice among engineers in industrial plants.
Today’s article will introduce another application of the TNR coupling, which is used for generators and diesel engines.

1. Characteristics of the Ringfeder TNR Coupling:

– The Ringfeder TNR coupling (Torsional Highflex Couplings TNR) has a rotational speed range from 1500 RPM to 6000 RPM.
– Torque: from 160 Nm to 68000 Nm.
– Operating environment: -50°C to +130°C.
– The TNR coupling is composed of 6 main components: SAE flange and outer sleeve + oil seal ring (o-ring) + damping rubber + shaft + protective cover + screws, additionally, a conical locking bush is only used in the TNR 2425.1 coupling.
– The Ringfeder TNR Buffer is made from natural synthetic rubber and polyurethane materials with various standard hardness levels.
– With a special hub and protective cover design featuring uniquely meshed gears, the free-vibrating damping rubber initially experiences shear stress and then compressive stress at the rated torque.
– The compact design of the coupling allows for installation in confined spaces.
– Worn parts can be easily replaced without needing to move the shaft or the machinery base.

2. Functions of the Ringfeder TNR Buffer:

When installing the damping rubber into the Ringfeder TNR coupling, you will see that the damping rubber fits between the slots of the hub and the outer protective cover. The specially designed cover has gear-shaped formations for a precise fit. As the coupling moves, the hub and the protective cover along with the damping rubber also move. Thanks to the high durability of the damping rubber, it can roll within the gear teeth without deforming or being damaged.
Part of the reason for this durability is that the damping rubber is made from high-quality materials, such as natural rubber or polyurethane, which possess a certain degree of elasticity and flexibility. Additionally, these materials can operate in environments with temperatures up to 130°C, meeting the demands of many modern factories.

3.  Ringfeder TNR Couplings for Generators and Diesel Engines According to SAE J 620 Standards:

Ringfeder TNR couplings are used in power plants and diesel engines as an excellent solution. By examining the illustration below, you can see that when using the TNR coupling between a diesel engine and a gearbox, the initial operation of the drivetrain causes a sudden increase in amplitude, which over time can affect the engine and gearbox.
However, by using the TNR coupling and the damping rubber, the drivetrain operates with consistent amplitude even at maximum speed. The Ringfeder coupling also compensates for angular, axial, and radial misalignments, reducing shock and torsional vibrations thanks to the damping rubber.
Overall, Ringfeder couplings bring many benefits to power plants, ensuring smoother drivetrain operation and optimizing vibration control. They save on maintenance costs and time due to their simple design, which allows for easy disassembly and assembly using just a wrench without the need to move the shaft or machine base.
The TNR shaft coupling, compliant with SAE J 620 standards, is extremely user-friendly and helps power plants operate more efficiently.
