ROTEX DFN JAW COUPLING WITH FLANGE CONNECTION ON BOTH SIDES

DESCRIPTION: Jaw coupling with flange connection on both sides - screwing of driving and driven side The torsionally flexible jaw coupling ROTEX DFN is an elastomer coupling with flange connection on both sides (flange coupling) for screwing of driving and driven machine. This torsionally flexible coupling is particularly suitable for applications in heavy engineering. The ROTEX DFN elastomer coupling with flange connection on both sides can be radially assembled and disassembled without displacing the adjacent power packs. This allows for quick replacement of spiders, too. The driving flanges and hubs are available from stock.

ROTEX torsionally flexible jaw couplings

ROTEX 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.
