Torsional stiffness and damping
The values stated in the above table apply to a capacity utilization
of 50 %, an excitation amplitude of 10 % T KN with the frequency
10 Hz and an ambient temperature of 20 °C. Dynamic
torsional stiffness is dependent on load and increases in proportion
to capacity utilization. The following table shows the correction
factors for different nominal loads.

Permitted shaft misalignment
The permitted shaft misalignment depends on the operating
speed. As the speed increases, lower shaft misalignment values
are permitted. The following table shows the correction factors
for different speeds.
The maximum speed for the respective coupling size and type
must be observed!

The damping coefficient is Ψ =1.4
Furthermore, torsional stiffness and damping depend on the
ambient temperature and the frequency and amplitude of the
torsional vibration excitation. More precise torsional stiffness
and damping parameters on request.

The axial misalignment may occur dynamically at frequencies
up to 10 Hz. For fitting, a maximum gap dimension of
Smax.=S+∆S and a minimum gap dimension of
Smin.=S–∆S are permitted.
Shaft misalignments ∆K a , ∆K r and ∆K w may occur simultaneously.
