KOL The values stated in the above table apply to a capacity utilization of 50%, an excitation amplitude of 10% T with a frequency of 10 Hz and an ambient KN temperature of 20 ｰC. The dynamic torsional stiffness is load-dependent and increases in proportion to capacity utilization. 48 92 ShoreA 310 620 4600 3500 7100 18055 2590 2.1 0.23 1 ψ = 0.75 for 64 ShD. Permitted shaft misalignment The permitted shaft misalignments ΔK , ΔK and ΔK are maximum values and must not occur simultaneously. The following formula can be used to roughly a r w calculate whether combinations of misalignments are permissible: ΔK ΔK ΔK r a w ΔK + ΔK + ΔK < 1 ract aact wact
