General Description

ROTEX® - couplings are torsionally flexible and designed for positive torque transmission. They are fail-safe. Operational vibrations and shocks areefficiently dampened and reduced. The two congruent coupling halves with concave claws on the inside are periphally offset in relation to one another by half a pitch.
In addition, they are designed in such a way as to enable an involute spider to be located between them.
The teeth of the spider are crowned to avoid edge pressure if the shafts are misaligned.
ROTEX® couplings are capable of compensating for axial, radial and angular displacements of the shafts to be connected.Performance

In contrast to other flexible couplings, the intermediate members of which are subject to bending stress and are therefore prone to earlier wear, the flexible teeth of ROTEX couplings are subject to pressure only. This gives the additional advantage of the individual teeth being able to accept considerably higher loads.The elastomer parts show deformation with load and excessive speeds. Sufficient space for expansion should be ensured.The maximum torsion angle with ROTEX couplings of any size amounts to 5° .

Explosion-proof use

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 category 2G/ 2D and thus suitable for the use in hazardous areas of zone 1, 2, 21 and 22.
