FLENDER Standard Couplings Flexible Couplings — N-EUPEX and N-EUPEX DS Series General information ■ Overview © Siemens AG 2011 7 N-EUPEX as overload-holding, fail-safe series N-EUPEX and N-EUPEX DS claw couplings connect machines. They compensate for shaft misalignment, generating only low restorative forces. The torque is conducted through elastomer flexibles, so the coupling has typically flexible rubber properties. N-EUPEX DS as overload-shedding, non-fail-safe series N-EUPEX couplings are overload-holding. By contrast, the N-EUPEX DS series is designed so that overload or advanced wear causes irreparable damage to the elastomer flexibles. The metal parts of N-EUPEX DS couplings can then rotate freely against one another without contact. (450) 655-7447 info@pt-dstech.com www.dstech.ca Elastomer flexible of the N-EUPEX series Elastomer flexible of the N-EUPEX DS series The flexibles of the N-EUPEX coupling are subjected to compression. If the flexibles 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. The flexibles of the N-EUPEX DS series are subjected to compression and bending forces. If the flexibles are irreparably damaged, the metal parts turn against one another without contact, and the power transmission is separated. Fitting new flexibles will make the coupling once more usable. The capacity of the N-EUPEX DS series to shed overloads is especially in demand for highly sensitive machines. 1275 Newton, local 15 Boucherville, Qc, Canada, J4B 5H2 G_MD10_XX_00068 N-EUPEX G_MD10_XX_00069 N- EUPEX - DS 7/2 Siemens MD 10.1 · 2011
© Siemens AG 2011 FLENDER Standard Couplings Flexible Couplings — N-EUPEX and N-EUPEX DS Series General information ■ Benefits N-EUPEX couplings are designed on the modular principle and have a very simple construction. N-EUPEX types are made up of subassemblies to suit requirements. The couplings are assembled by simply fitting the coupling halves together. Wear is restricted to the elastomer flexibles, which must be replaced at the end of their service life. Depending on type, the elastomer flexibles can be changed without moving the coupled machines. The coupling parts are readily available from stock and are mostly finish-machined, i.e. with finished bore, keyway, set screw and balancing. Optionally: The wear indicator for N-EUPEX couplings enables the condition of the flexible to be easily assessed. The wear condition can also be ascertained with the aid of a stroboscope while the coupling is rotating. The production process can thus continue undisturbed. If the stroboscope is to be used in a potentially explosive environment, you can enquire about the equipment for this at Siemens. Pocket part (part 1, 10) 1275 Newton, local 15 Boucherville, Qc, Canada, J4B 5H2 ■ Application The N-EUPEX coupling is available as a catalog standard in 23 sizes with a rated torque of between 19 Nm and 62000 Nm. The coupling is suitable for use at ambient temperatures of between -30 °C and +80 °C. By using alternative elastomer buffers, the permissible ambient temperature range can be extended to between -50 °C and +100 °C. G_MD10_EN_00176 Cam part (part 3, 4, 7) The wear indicator must be attached to the outside diameter of the coupling after the coupling has been fitted. In the case of diesel engine drives, the actual dynamic coupling load should be checked by measurement or torsional vibration calculations. 7 Frequently, the coupling is used to connect the motor to the gear unit input shaft. The coupling is suitable especially for drives with uniform to average dynamic loads. Examples of applications are pump drives, ventilator drives or crane running gear. Furthermore, N-EUPEX couplings can be used as add-on couplings, particularly on FLUDEX fluid couplings or ARPEX AKR safety couplings. In the case of drives with a diesel engine, N-EUPEX couplings are suitable for driven machines with a low mass moment of inertia. Coupling suitable for potentially explosive environments. Complies with Directive 94/9/EC for: II 2 G T4 / T5 / T6 D120 °C -30 °C ≤ T a ≤ +80 °C / +50 °C / +40 °C I M2 ■ Function (450) 655-7447 info@pt-dstech.com www.dstech.ca The motor torque is transmitted to the hub at the drive end via the shaft-hub connection, which is mostly designed as a keyway connection. The torque is transmitted to the hub on the output side with the aid of elastomer flexibles. The hub on the output side further transmits the torque to the driven machine or a gear unit placed in between. Because of the primarily compressionloaded elastomer flexibles, the coupling has a progressive torsional stiffness. In the case of the N-EUPEX DS coupling series, the elastomer flexible is subjected to bending and compression loads. In the event of overload or advanced wear, the coupling disconnects positively and the flexibles are irreparably damaged. The metal parts then rotate without touching one another. After new elastomer flexibles are fitted, the N-EUPEX DS coupling is once more operable. N-EUPEX DS couplings are maintenance-free, even in potentially explosive environments, so long as the possible torque interruption does not lead to an unacceptable disruption of the production process.
