Description
The type RINGFEDER® TND QCQ is a torsionally stiff, backlash-free steel disc coupling consisting of two hubs with open flange Q prepared to be equipped with shrink discs of the series RINGFEDER® RfN 4061 and a compact-spacer C that can be installed and removed radially. Using high-strength screws, one disc pack each is connected to the spacer and one hub, thus achieving the function of a double-cardanic system.
Depending on the coupling size, two different disc packs are available:
*Type HD (= High Deflection) for increased compensation capability at occurring shaft misalignments.
*Type HT (= High Torque) with larger power density for higher requirements on transmissible torque.
The double-jointed design with two disc packs compensates for angular, axial and radial shaft misalignments with minimum axial space requirement. A permanently backlash-free fixation of the coupling hubs on the shafts to be connected is realized by means of high-quality RINGFEDER® Shrink Discs.
