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. C Tdyn = C Tdyn 50 % ⋅ FKC Correction factor FKC 65/80/90 ShoreA Capacity utilization T N / T KN 20 % 40 % 50 % 60 % 70 % 80 % 100 % 0.54 0.84 1.00 1.18 1.36 1.55 1.97 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 must be observed! ∆K perm = ∆K 1500 ⋅ FKV Speed in rpm 500 1000 1500 3000 Correction factor FKV 1.7 1.2 1.0 0.70 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 S min. = S – ∆S are permitted. Shaft misalignments ∆K a , ∆K r and ∆K w may occur simultaneously. The damping coefficient is Ψ =1.4 (450) 655-7447 info@pt-dstech.com www.dstech.ca 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. 1) The maximum speed of the respective type must be noted. For further information on permissible shaft misalignment, please see the operating instructions. 2) Does not apply to type H. Siemens MD 10.1 · 2011 7/7
