ROTEX® CFN

Product image ROTEX CF CFN DF DFN flange program CFN

ROTEX® CFN

0 - 35,000 Nm / jaw coupling with flange connection on one side

Product request Downloads

The torsionally flexible jaw coupling ROTEX CFN is an elastomer coupling with a flange connection on one side (flange coupling) and particularly suitable for applications in heavy engineering.

Type CFN of the ROTEX elastomer coupling is characterized by the double flange design allowing for radial assembly and disassembly of the shaft coupling or elastomer without displacing the driving or driven side.

The driving flange and the hubs are available from stock.

Features

torsionally flexible jaw coupling as a flange type for heavy engineering
radially mountable without displacing the driving components
particularly short mounting length
flange material: 3b made of GGG40 (nodular iron)
customized mounting flanges on request

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 allow for 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:

Jaw couplings ensure torsional vibration-damping power transmission absorbing shocks generated by irregularly operating machines. 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 withstand significantly higher loads.

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

All sizes of ROTEX jaw 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® (elastomer) material by the colours orange (92 Shore A), purple (98 Shore A) and light green (64 Shore D).
