Description of coupling
COUNTEX® is a three-part, backlash-free and torsionally stiff coupling which was specifically developed based on the demands from measuring and control technology. The ability for axial plug-in combined with the hub geometry results in a coupling system particularly easy to install. COUNTEX® is available in three sizes.
The measuring and control technology requires a high amount of torsion spring stiffness from the coupling to achieve reproducible positioning. At the same time the coupling needs to compensate for displacements without any big forces affecting the adjacent filigree components of the system. The spacer of our COUNTEX® made of highly temperature-resistant nylon ensures an almost constant torsion spring stiffness even with high temperatures. The double-cardanic operating principle of COUNTEX® reduces the restoring forces to a minimum. Nevertheless it has very short dimensions which are excellently suitable for narrow mounting spaces.
COUNTEX® 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.
