Examples of particularly safety-relevant areas of application are cable railway drives, lifting gear for crane drives or escalator drives. Design andConfigurations ® A RUPEX coupling comprises two hub sections which are mounted on the machine shafts. The hub parts are connected positively by steel pins and elastomer elements. The coupling can be fitted with add-on parts such as brake disks or brake drums. Up to size 360, the pins and buffers are fitted on one side. From size 400 up, the pins and buffers are fitted in the hubs on alternate sides. Frequently, the coupling is used to connect the gear shaft to the driven machine. In the case of drives without gear units, the coupling is particularly suitable for operation in harsh conditions or heavy-duty drives with electric motor drive. Ventilator drives with high ventilator mass and drives in the cement industry are typical applications. Coupling suitable for use in potentially explosive atmospheres. II 2GEx h IICT6 ... T4Gb X ® RUPEX couplings can also hold loads when overloaded and are therefore especially suitable for drives for special safety and reliability requirements. ® RUPEX couplings are suitable for reversing operation and horizontal and vertical fitting or fitting at any required angle. Application Complies with the current ATEX Directive for: ® RUPEX pin and bush couplings link machine shafts and compensate for shaft misalignment with weak restorative forces. ® Thanks to their robust design, RUPEX couplings are also suitable for harsh operating conditions. Benefits ® Torque shock loads and changing loads are no problem for robust, compact flexible RUPEX couplings. ® RUPEX couplings are fitted by putting together the coupling halves. Fitting with low torsional backlash is simplified by the barrel-shaped geometry of the buffers. The steel variant is especially suitable for high-speed drives. The torque is conducted through elastomer elements, so the coupling has typically flexible rubber properties. II 2DEx h IIICT85 °C ... 110 °CDb X ® RUPEX couplings require little maintenance. Only the elastomer elements, as wear parts, need be replaced and the coupled machines do not need to be moved to do so. I M2 Ex hMb X ® RUPEX couplings are available as a catalogue standard in 26 sizes with a rated torque of between 200 Nmand 1,300,000 Nm. The coupling is suitable for use at ambient temperatures of between -30°C and +80°C. By using alternative elastomer elements, the permissible ambient temperature range can be extended to between -50°C and +100°C. 1 #DriveLineHarmony Rupex Series Introduction Torsionally Flexible Couplings www.jbj.co.uk/couplings.html#flender
