permitted only five times per hour.
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.
