® ® ELPEX-B couplings are highly flexible and free of torsional backlash. Because of their low torsional stiffness and damping capacity, ELPEX-B couplings are ® especially suitable for coupling machines with a highly non uniform torque pattern. ELPEX-B couplings are also suitable for connecting machines with high shaft misalignment. The elastic tire can simply be slipped over the hub parts. The elastic tire is held firmly in place by fitting the clamping ring. The connection transmits the torque by frictional engagement. ® Standard ELPEX-B coupling types are designed as shaft-shaft connections.Application-related types can be implemented on request. Benefits ® The ELPEX-B coupling is suitable for horizontal and vertical mounting positions or mounting positions at any required angle. The coupling parts can be arranged as required on the shafts to be connected. If the elastic tyre is irreparably damaged or worn, the metal parts can rotate freely against one another because they are not in contact with one another. Application ® ® ELPEX-B couplings are highly flexible and free of torsional backlash. Because of their low torsional stiffness and damping capacity, ELPEX-B couplings are ® especially suitable for coupling machines with a highly non uniform torque pattern. ELPEX-B couplings are also suitable for connecting machines with high shaft misalignment. ® Standard ELPEX-B coupling types are designed as shaft-shaft connections.Application-related types can be implemented on request. ® The ELPEX-B coupling's transmission characteristic is determined essentially by the elastic tire. The elastic tire is manufactured from a natural rubber or a chloroprene rubber mixture with amultiply fabric insert. The elastic tire is fastened to the hubs with bolts and two clamping rings. In type EBWT, the shaft-hub connection is achieved with Taper clamping bushes, in type EBWN with finish-drilled hubs and parallel keys. The type EBWZ connects themachine shafts additionally via a detachable adaptor. The elastic tire is slit at the circumference and can be changed without having tomove the coupledmachines. ® The ELPEX-B coupling is available as a catalogue standard in 15 sizes with a rated torque of between 24 Nm and 14500 Nm. The coupling can be fitted with elastic tires made of natural rubber for ambient temperatures of -50 °C to +50 °C and with elastic tires made of chloroprene rubber for -15 °C to +70 °C. The elastic tyre is fitted without backlash and gives the coupling linear torsional stiffness, thus the torsional rigidity remains constant as the load on the coupling increases. ® The ELPEX-B coupling is especially suitable for reversing operation or operation with changing directions of load. Design andConfigurations The chloroprene rubber tire is marked FRAS, "Fire-resistant and Antistatic". 1 #DriveLineHarmony ELPEX-B Series Introduction Highly Flexible Couplings Fitted coupling (shown without connecting shafts) Fitted elastic tire Unfitted coupling www.jbj.co.uk/couplings.html#flender
