Safety Couplings TNT – Smart Overload Protection for Modern Industry

2. Characteristics and classification of Safety Couplings TNT:

- Couplings with clutches of the TNT series have the ability to effectively compensate for shaft misalignment, are easy to install and handle and have absolutely no kickback.
- Couplings have specially developed and standardized switches, of which up to twelve are located around the circumference of the coupling for overload protection.
- Technical specifications:
Shaft hole diameter d: 90 - 200mm
Overall length L: 180 - 292 mm
Torque T: 1950 - 42400 Nm
- Safety Couplings TNT is a prominent overload protection coupling with product lines: TNT 2420, TNT 2424, TNT 2425:
TNT 2420 is a standard plain coupling combined with Flange and Keyway Hub
TNT 2424 is a coupling integrated with Torsionally Rigid Steel Disc Coupling
TNT 2425 is a coupling combined with Elastic Jaw Coupling

3. Working principle of TNT overload protection coupling:

TNT safety couplings operate according to the proven ball-catching principle. During machine operation, the two halves of the coupling will automatically separate when detecting excessive torque transmission, exceeding the previously set parameters, helping to disconnect the input and output of the system, minimizing damage to the motor.
This principle is based on a standard switching unit, considered the center of the coupling, with twelve units arranged around the coupling. This ensures flexibility in disconnection torque and coupling size.

4. Applications of Safety Couplings TNT in industries

With the ability to effectively compensate for shaft misalignment, easy installation and handling as well as completely free of play, Ringfeder Safety Couplings are widely used in fields such as::
- Construction: Typically, construction machinery such as: excavators, crushers, shredders and grading and tunnel boring machines.
- Steel mill: Application in rolling mill systems, turbines, industrial conveyor systems
- Wood manufacturing plants: In this factory, Safety Couplings are used in planers, crushers and conveyor systems.
- Marine industry: Ensuring safety for transmission systems on ships such as cranes & hoists, Pumps & Compressors
