RADEX®-N es un acoplamiento totalmente de acero, exento de juego, rígido a la rotación y exentos de mantenimiento. Las laminillas extremadamente rígidas en dirección de rotación de acero para muelles inoxidable de alta resistencia posibilitan la compensación de elevados valores de desplazamiento con reducidas fuerzas de retroceso. En función de la ejecución totalmente de acero, RADEX®-N puede ser empleado en accionamientos con temperaturas hasta 280° C.

FEM-optimized laminae form

The steel laminae packings from stainless spring steel were developed on the basis of FEM calculations. Under consideration of the necessary possibilities of displacements of the coupling the optimal form regarding torque transmission and torsional rigidity was aimed for. The fitted form of the steel laminae at the outside diameter is the result of this optimization calculation.

Laminae packings with dowel screws

The „heart“ of the steel laminae coupling are the laminae packings and their connection to the hubs or spacers.

High-strength, special dowel screws that are alternately screwed with hubs and spacer enable a combination of frictional engagement and positive locking. Thus a high power density with simultaneous easy displacement and low restoring forces is guaranteed.

Due to the special constructive design of the RADEX®-N components the laminae packings are „artificially“ prestressed. Hereby the torsional rigidity of approx. 30 % is enabled and at the same time the known problem regarding the axial vibrations of the spacer is avoided.

General description

The RADEX®-N is a backlash-free, torsionally-stiff and maintenance-free all-steel coupling. By using CFK pipes considerably larger shaft distance dimensions are possible compared to comparable steel pipes. The dimensioning of CFK pipes is "custom-made" to the application and is optimally adjusted to the respective case of operation.
