FLENDER Standard Couplings Flexible Couplings — N-BIPEX Series © Siemens AG 2015 General ■ Technical specifications Cam rings Cam rings of polyurethane 92 ShoreA (standard) Cam rings of polyurethane 95 ShoreA (ordering option -Z and order code K01 ) 9 Cam rings of polyurethane 64 ShoreD (ordering option -Z and order code K04 ) Torsional stiffness and damping Furthermore, torsional stiffness and damping depend on the am- bient temperature, the frequency and the amplitude of the tor- sional vibration excitation. More precise torsional stiffness and damping parameters on request.
The values stated in the above table apply to a capacity utiliza- tion of 50 %, an excitation amplitude of 10 % T KN with frequency 10 Hz and an ambient temperature of 20 °C. The dynamic tor- sional stiffness ( C Tdyn ) is load-dependent and increases in pro- portion to capacity utilization. The following table shows the cor- rection factors for different nominal load. With flexible couplings the manufacturing process of the rubber elements and their aging primarily influence the stiffness value C Tdyn . For this reason calculation must be made with a tolerance for the dynamic stiffness of ± 20 %.
The specified damping coef- ficient Ψ is a minimum value with the result that the damping per- formance of the coupling corresponds at least to the specified value.
