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 Couplings N-Eupex Series Introduction N-EUPEX as overload-holding, fail-safe series N-EUPEX DS as overload-shedding, non-fail-safe series Coupling suitable for use in potentially explosive atmospheres. Complies with the current ATEX Directive for: II 2G Ex h IIC T6 ... T4 Gb X II 2D Ex h IIIC T85 °C ... 110 °C Db X I M2 Ex h Mb X N-EUPEX and N-EUPEX DS claw couplings (also known as pin / cam couplings) connect machines. They compensate for shaft misalignment, generating only low restorative forces. The torque is transmitted through elastomer elements, so the coupling has...

Torsionally Flexible Couplings N-Eupex Series Introduction Elastomer element of the N-EUPEX series The elements of the N-EUPEX coupling are subjected to compression. If the elements are irreparably damaged, the hub parts come into contact with metal. This "emergency operation capability" is required, e.g., in the case of fire pump drives. Elastomer flexible of the N-EUPEX DS series The elements of the N-EUPEX DS series are subjected to compression and bending forces. If the elements are irreparably damaged, the metal parts turn against one another without contact, and the power transmission is...

Torsionally Flexible Couplings N-Eupex & N-Eupex DS Technical Specifications The damping coefficient is y = 1.4 Torsional stiffness and damping is further dependent on the ambient temperature and the frequency and amplitude of the torsional vibration excitation. More precise torsional stiffness and damping parameters on request. With flexible couplings the manufacturing process of the rubber elements and their aging primarily influence the stiffness value CTdyn. For this reason calculation must be made with a tolerance for the dynamic stiffness of ± 20 %. The specified damping coefficient y is a minimum...
