Flender Mechanical Power Transmission Couplings available from jbj Techniques FLUDEX couplings are hydrodynamic fluid couplings which operate on the Fottinger principle. FLUDEX® couplings limit starting and maximum torque in the drive train and, through the property of rotational slip, serve as an aid to starting the motor, as overload protection in the event of fault and for isolating torsional vibration. To compensate for shaft misalignment, the FLUDEX® coupling is combined with a displacement coupling e.g. of the N-EUPEX® type. Railway Couplings Couplings for rail vehicles developed, tested...

Torsionally Flexible Jaw Couplings N-Bipex Series General Information Coupling suitable for use in potentially explosive atmospheres. Complies with the current ATEX Directive for: II 2G Ex h IIB T6 ... T4 Gb X II 2D Ex h IIIC T85 °C ... 120 °C Db X I M2 Ex h Mb X N-BIPEX couplings are torsionally flexible and are outstanding for their particularly compact design and low weight. N-BIPEX couplings are used in many areas of mechanical engineering. Their main area of use is in electric motor drives which are well aligned and have uniform torque loads, such as in hydraulic applications and in combinations...

Torsionally Flexible Jaw Couplings N-Bipex Series General Information An additional size marking has been provided on the outer surface of the coupling element to be able to determine the size of the N-BIPEX even when it is in the assembled state without having to use any additional aids. The coupling is suitable for use at ambient temperatures between -50 °C and +100°C without any restrictions on the rated torque as a result of temperature factors. Function The torque is transmitted to the hub at the drive end via the shaft-hub connection, which is mostly designed as a keyway connection, and...

Torsionally Flexible Jaw Couplings Size Undrilled N-Bipex Series General Information Torsional Stiffness and Damping The values stated in the above table apply to a capacity utilization of 50%, an excitation amplitude of 10% TKN with frequency 10 Hz and an ambient temperature of 20°C. The dynamic torsional stiffness (CTdyn) is load-dependent and increases in proportion to capacity utilization. The following table shows the correction factors for different nominal load. CTdyn = CTdyn 50 % • FKC Correction factor FKC 92/95 Shore A and 64 Shore D Furthermore, torsional stiffness and damping depend on...
