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.
