The permitted shaft misalignments ?Ka , ?Kr and ?Kw are maximum values and must not occur at the same time (see following table). The permitted shaft misalignment ?Kr applies to the shaft distance S specified in each case.
The values for torsional stiffness apply to the complete coupling. The torsional stiffness of the plate packs applies to the rated coupling torque T KN . To determine the torsional stiffness for a specific operating point, e.g. for calculating torsional vibration, the manufacturer must be consulted.
T Kmax permitted only five times per hour.
