<strong>FLENDER</strong> <strong>Standard</strong> <strong>Couplings</strong><br />
Flexible <strong>Couplings</strong> — RUPEX Series<br />
General information<br />
For maximum coupling torque:<br />
T Kmax =3.0⋅ T KN<br />
For overload torque:<br />
T KOL =4⋅ T KN<br />
For coupling fatigue torque:<br />
T KW =0.20⋅ T KN<br />
The axial misalignment may occur dynamically at frequencies<br />
up to 10 Hz.<br />
For fitting, a maximum gap dimension of S max. = S + ∆S and a<br />
minimum gap dimension of S min. = S – ∆S are permitted.<br />
Torsional stiffness and damping<br />
The values stated in the above table apply to a capacity utilization<br />
of 50 %, an excitation amplitude of 10 % T KN with the frequency<br />
10 Hz and an ambient temperature of 20 °C. Dynamic<br />
torsional stiffness is dependent on load and increases in proportion<br />
to capacity utilization. The following table shows the correction<br />
factors for different nominal loads.<br />
C Tdyn = C Tdyn 50 % ⋅ FKC<br />
Permitted shaft misalignment<br />
The permitted shaft misalignment depends on the operating<br />
speed. As the speed increases, lower shaft misalignment values<br />
are permitted. The following table shows the correction factors<br />
for different speeds.<br />
The maximum speed for the respective coupling size and type<br />
must be observed!<br />
∆K perm = ∆K 1500 ⋅ FKV<br />

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

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