Technical data
Power ratings
Torsional stiffness depends on the ambient temperature and the
frequency and amplitude of the torsional vibration excitation.
More precise torsional stiffness and damping parameters on re-
quest.
With elastic couplings the manufacturing process of the rubber
elements and their aging primarily influence the rigidity value
C
Tdyn
. For this reason calculation must be made with a tolerance
for the dynamic rigidity of
±
20 %. The specified damping coeffi-
cient
Ψ
is a minimum value with the result that the damping per-
formance of the coupling corresponds at least to the specified
value.
