ROTEX® couplings are suitable for power transmission in drives in hazardous areas. The couplings are certified and confirmed according to EC standard 94/9/EC (ATEX 95) as units of

General description ROTEX®couplings are torsionally flexible and designed for positive torque transmission. They are fail-safe. Operational vibrations and shocks are efficiently dampened and re- duced. The two congruent coupling halves with concave claws on the inside are periphally offset in relation to one another by half a pitch.

ROTEX® Standard - torsionally flexible jaw coupling The original - renowned industrial standard. The torsionally flexible jaw coupling ROTEX Standard is an elastomer coupling with feather

The ROTEX couplings are in a position to compensate for radial and angular displacements. Careful and accurate alignment of the shafts increases the service life of the coupling. In case of pure angular misalign- ment the imagined bisecting lines of the shafts intersect in the middle of the coupling.

These three pieces are co-axially assembled to complete the GR coupling. After assembly these couplings becomes sufficient flexible, positive motion and power transmitting fail safe coupling elements. Due to polyurethane spider, both the metallic hubs are separated from each other to avoid there physical contact.

The above misalignment figures for ROTEX® couplings are standard values, taking into account the load of the coupling up to the rated torque T KN and an operating speed n = 1,800 RPM

ROTEX®is a torsionally flexible jaw coupling. It is able to compensate for shaft misalignment, for example caused by manufacturing inaccuracies, thermal expansion, etc. Type AFN-SB spec. allows to replace the spider or brake disk without dismounting the driving or driven machine. 1 Technical data 3 2 Advice 4
