Product Characteristics

RINGFEDER® TNR

The RINGFEDER® TNR coupling has specifically been designed and optimized for use primarily in internal combustion engines. In such applications, dynamic disturbances are caused by periodic excitation and utilization of a large speed range. It is therefore necessary to shift unavoidable resonances by deliberately adjusting the stiffness.

The new RINGFEDER® TNR – a compact, plug-in configuration, optionally available as puncture-proof or not fail-safe design, and dynamically adjustable over a wide temperature range.

Key data:

  • Dynamic stiffness: elastic to highly elastic transmission capability
  • Torque [Nm]: 144 to 9600
  • Speed [rpm]: 1200 to 4750
  • Temperature range: -50°C to +230°C

Every drive line has its characteristic torsional vibration behaviour and the newly developed coupling RINGFEDER® TNR ensures optimum tuning of the dynamic stiffness to suit any application.

Properties/Benefits

  • Purposeful adjustment of the dynamic properties by varying the elastomeric bufferst
  • Not fail safe, but can be made puncture-proof by simple modification
  • Very compact design allows installation in confined spaces
  • Easy replacement of wear parts without having to remove the hubs or flanges
  • On account of the modular construction system, even custom solutions can be realized at low cost
  • Cost-neutral adaptation of the stiffness, also for individual projects.
  • Taper bushing bore see catalog page 32
