General information
6
Power ratings, type MCECM
The permitted shaft misalignments
Δ
K
a
,
Δ
K
r
and
Δ
K
w
are maxi-
mum values and must not occur at the same time
(see following
table).
The permitted shaft misalignment
Δ
K
r
applies to the shaft
distance S specified in each case.
T
Kmax
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.
