En el caso de DKM se trata de una ejecución doblemente cardánica del ROTEX® GS. Este se emplea en todo lugar donde deben ser compensados grandes desplazamientos de árboles o se deben puentear medidas de distancia de árboles. ROTEX® GS DKM es combinable con diferentes ejecuciones de cubos de ROTEX® GS.

Performance

Apart from the jaw-type geometry of the coupling hubs the zero backlash of the ROTEX® GS is mainly due to the geometry of the ROTEX® GS spiders. These are designed in a way that the convex teeth of the spider contact the concave jaws of the coupling hub under prestress. In combination with the straight toothing this results in a small surface pressure and an increased stiffness of the coupling system. 

Spiders

The flexible spiders for the GS series are available in five different kinds of Shore hardness. The different kinds of Shore hardness allow to adjust ROTEX® GS easily to the individual conditions of an application with regard to torsional stiffness and vibration characteristics.

The flexible teeth are radially supported by a web on the inside diameter. In this way deformation caused by heavy acceleration or high speeds is prevented.

The permissible ambient temperature of the coupling depends on the Shore hardness of the spider.

ROTEX® GS DKM

This type is certified and confirmed according to EC standard 94/9/EC (ATEX 95) as unit of category 2G/2D and thus suitable for the use in hazardous areas of zone 1, 2, 21 and 22. 

Please read through our information included in the respective Type Examination Certificate and the operating and mounting instructions.

Addition: If clamping ring hubs (clamping hubs without keyway are only permitted for category 3) are used in hazardous areas the coupling must be designed in a way that between the peak torque including all operating parameters and the torque of frictional engagement and the nominal torque of the coupling, resp., there is a safety of at least s=2.
