Coupling description The RADEX®-NC is a line particularly developed for the servo   technology. In this coupling a package of torsionally rigid steel   laminae that are soft in bending ensures a reliable compensation for   axial, angular and radial shaft displacements. As all-metal coupling -   the laminae are made from stainless steel - the RADEX®-NC can even be   used with high temperatures (up to 200 °C) and under aggressive ambient   conditions. The RADEX®-NC is manufactured in 6 sizes from size 5 to 35   for max. torques of up to 200 Nm. The hubs are frictionally engaged clamping hubs made from aluminium   (size 42 made from steel) and are thus backlash-free even in a reversing   drive.
Application                                                         
A typical application of the RADEX®-NC are backlash-free worm   gear pairs with low transmissions. The rigidity of the coupling must be   converted by reason of the transmission of the gearbox from the drive   side to the driven side. Here the transmission itself has a decisive influence because it is   squarely included in the calculation. This converted rigidity is added   in line to the gearbox stiffness in order to get the total rigidity. In   case of transmissions that are lower than i = 8 we recommend to use the   RADEX®-NC due to the loss of rigidity of the total system if flexible   couplings are used.
     
Explosion protection use                                         
RADEX®-NC couplings are suitable for power transmission in drives in hazardous areas. The couplings are certified and confirmed according to ECstandard 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.
