Coupling description ROTEX® GS is a 3-part, axial plug-in coupling backlash-free underpre-stress. It is convincing even with critical applications by itsbacklash-free power transmission, its stiffness which is each adapted tothe application and its optimum damping of vibrations. This principleof installation offers significant assembly possibilities which optimizethe assembly times in production.
General description
The straight toothing of the spider mounted under prestressresults in a smaller surface pressure and consequently higher stiffnessof the coupling system. The flexible teeth compensate for misalignmentbut are supported radially in the inside diameter by a central web. Thisavoids too high internal or external deformation by high accelerationor high speeds. This is vital for a smooth operation and long servicelife of the coupling.
Performance

The hub claws and the nylon teeth are chamfered to allow for a"blind assembly". The pegs arranged reciprocally on the spider preventthe spider from touching the hub over the entire surface. Observing thedistance dimension E ensures the ability of the coupling to compensatefor displacements. The plug-in force varies depending on the Shorehardness and prestress of the spider (see comments in the mountinginstructions KTR-N 45510). By observing the gap dimension "s" the electrical isolation isensured, as well as a high service life of the coupling. This fact isgaining more and more importance, due to the increasing precision ofshaft encoders and the existing demand for electro-magneticcompatibility. Explosion-proof use

ROTEX® GS couplings are suitable for power transmission in drivesin hazardous areas. The couplings are certified and confirmed accordingto EC standard 94/9/EC (ATEX 95) as units of category 2G/2D and thussuitable for the use in hazardous areas of zone 1, 2, 21 and 22.

Spiders
The elastic spiders of the GS line are available in threedifferent kinds of Shore hardness, identified by colour, the materialbeing soft to hard. Due to these four spiders with different kinds ofShore hardness it is easily possible to adjust the ROTEX® GS regardingthe torsional stiffness and the vibration behaviour to the individualconditions of an application.
