P R E C A U T I O N !
Clamping hubs without feather key may be used in category 3 only.
A T T E N T I O N !
Selection of clamping hubs
With the use in explosion-proof areas the clamping hubs have to be selected in a way that
the difference between the peak torque of the machine including all operation parameters
and the frictionally engaged torque of the clamping ring hub is at least a service factor of
s = 2.
2 Hints
2.1 Coupling Selection
!
C A U T I O N !
For a continuous and troublefree operation of the coupling it must be designed according to
the selection instructions (according to DIN 740 part 2) for the particular application
(see RADEX
®
-NC catalogue).
If the operating conditions (performance, speed, changes at engine and machine) change,
the coupling selection must be checked again.
Please make sure that the technical data regarding torque only refers to the laminae
packages. The transmissible torque of the shaft/hub connection must be checked by the
orderer, and he is responsible for the same.
For drives with endangered torsional vibration (drives with periodical load on torsional vibration) it is necessary to
make a torsional vibration calculation to ensure a perfect selection. Typical drives with endangered torsional
vibration are e. g. drives with diesel engines, piston pumps, piston compressors etc. On request KTR makes the
coupling selection and the torsional vibration calculation.
