KTR ROTEX COUPLING BFN

DESCRIPTION: KTR ROTEX BFN is a torsionally flexible elastomer coupling as a flange type (flange coupling) and particularly suitable for applications in heavy engineering. The BFN design of the ROTEX elastomer coupling is characterized by the flange type allowing for radial assembly and disassembly of the shaft coupling or the elastomer without displacing the driving or driven side. The flange hub 4N of the torsionally jaw coupling as a flange type ROTEX BFN is made of steel and the driving flange 3Na is made of GJS.

Characteristic Rotex BFN Flexible Coupling

ROTEX BFN torsionally flexible jaw couplings are elastomer couplings characterized by a compact design.
In spite of low weights and mass moments of inertia of the elastomer couplings they are able to transmit high torques. The compact shaft couplings are characterized by a long service life and sound operating characteristics generated by allover machining.

Thanks to the elastomer (elastomer spider) between the coupling hubs of the jaw couplings shocks respectively torsional vibrations in the drive train are damped. The high temperature-resistant spider material T-PUR® (elastomer) is available in various degrees of hardness. The torsionally flexible ROTEX couplings are used in almost every range of general machinery and plant engineering.

Overview: torsionally flexible shaft couplings Rotex BFN / elastomer couplings

Properties of torsionally flexible jaw couplings:
ROTEX shaft couplings consist of two hubs (aluminium or steel) and a spider (elastomer ring / cam ring) made of T-PUR. The different degrees of hardness of the T-PUR-spider allow to adjust the level of damping and torsional stiffness of the elastomer coupling.

ROTEX couplings require few mounting space and thus enable easy assembly/disassembly. The numerous types provide for maximum flexibility and meet with the different mounting requirements through various types of hubs.

Function of torsionally flexible jaw couplings Rotex BFN:

Jaw couplings ensure torsional vibration-damping power transmission and absorb shocks generated by machines with irregular operation.
In contrast to flexible couplings the connecting elements of which are subjected to bending and therefore to earlier wear, the flexible teeth of ROTEX® couplings (elastomers) are subjected to compressive stress only. The benefit of the elastomer coupling thus is to resist significantly higher loads.

The elastomers become deformed with load and high speeds. Sufficient expansion space must be provided.

All sizes of ROTEX® elastomer couplings have a maximum torsion angle of 5°. They can be mounted both horizontally and vertically.

Material of torsionally flexible jaw couplings:
Our elastomer material T-PUR is resistant to higher temperatures and has a considerably longer service life than common polyurethanes. From a visual point of view we marked the T-Pur material by the colours orange (92 Shore A), purple (98 Shore A) and light green (64 Shore D).

The previous polyurethane spiders in the colours yellow, red and natural white with green marking of teeth continue to be available on request.
