® ® 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

The coupling types set up for shaft-hub connections with Taper clamping bushes are designated as follows: » VariantA: Coupling with part 3 – part 3 » Variant B: Coupling with part 4 – part 4 » VariantAB: Coupling with part 3 – part 4 In the case of part 3, the Taper clamping bush is screwed in from the shaft end face side. The coupling half must be fitted before the machines to be connected are pushed together. In the case of part 4, the Taper clamping bush is screwed in from the machine-housing side. If there is insufficient room, the Taper clamping bushes cannot be fitted from this side. Besides fitting space for the Taper clamping bush bolts, space for the fitting tool (offset screwdriver) must be taken into account. In the case of coupling type EBWT, part 3 and part 4 can be combined as required. Furthermore, the variant with a Taper clamping bush can be combined with the finish drilled hub.

www.jbj.co.uk/couplings.html#flender 3 #DriveLineHarmony ELPEX-B Series Introduction Highly Flexible Couplings The permitted shaft misalignment depends on the operating speed. As the speed increases, lower shaft misalignment values are permitted. The correction factors for different speeds are specified in the following table. Themaximum speed for the respective coupling sizemust be noted. With flexible couplings the manufacturing process of the rubber elements and their aging primarily influence the stiffness value C . For this reason Tdyn calculation must be made with a tolerance for the dynamic stiffness of ±20%. The specified damping coefficient Ψ is a minimum value with the result that the damping performance of the coupling corresponds at least to the specified value. 500 1000 1500 3000 Restorative forces on request. Correction factor FKV 1.2 1.1 1.0 0.7 The damping coefficient isΨ= 0.9 Torsional stiffness depends on the ambient temperature and the frequency and amplitude of the torsional vibration excitation. More precise torsional stiffness and damping parameters on request. ΔKperm= ΔK1500 ⋅ FKV The restorative force (including in the axial direction) depends on speed, system torque and shaft misalignment.

www.jbj.co.uk/couplings.html#flender 11 #DriveLineHarmony ELPEX-S Series Introduction Highly Flexible Couplings Complies with the current ATEX Directive for: II 2GEx h IICT4 ... T3Gb X Coupling suitable for use in potentially explosive atmospheres. II 2DEx h IIICT120 °C ... 160 °CDb X I M2 Ex hMb X (Type EST is not available in Ex version.) ELPEX-S couplings are highly torsionally flexible and because of their low torsional stiffness and damping capacity are especially suitable for coupling machines with a highly non uniform torque pattern. Standard ELPEX-S coupling types are designed as flange-shaft-connections or shaft-shaft connections. Application-related types can be implemented on request Benefits The ELPEX-S coupling is suitable for horizontal and vertical mounting positions or mounting at any required angle. The coupling parts can be arranged as required on the shafts to be connected. ELPEX-S couplings are especially suitable for reversing operation or operation with changing directions of load. The rubber disk elements are fitted virtually without backlash and give the coupling linear torsional stiffness, i.e. the torsion stiffness remains constant even when the load on the coupling increases. There are 4 different rubber element versions with different grades of torsional stiffness available for each size from stock. The ELPEX-S coupling is available as a catalog standard in 12 sizes with rated torques of between 330 Nmand 63000 Nm. The rubber disk element is vulcanized onto a flange on the inside diameter. The flange can mount e.g. a taper clamping bush or a hub. On its outer diameter the rubber disk element has driving teeth, which are inserted into the outer flange. The torque is transmitted positively between the rubber disk element and the outer flange. In the type for shaft-shaft connection the outer flange is screwed to a flange hubmounted on amachine shaft. The coupling is suitable for ambient temperatures of between -40 °C and +120 °C. The ELPEX-S coupling is frequently used for diesel motor drives or reciprocating compressor drives. There are outer flanges with different connection dimensions available for each coupling size. Design &Configurations On certain types the flexible rings can be changed without having tomove the coupledmachines. Application If substantial overload occurs, the rubber disk element of the coupling is irreparably damaged, the coupling throws the load and thus limits the overload for particular operating conditions. The coupling can be inserted and fitted blind e.g. in a bell housing. Because the different rubber versions enable the torsional stiffness to be adjusted to meet requirements, the coupling is also suitable for drives which require a specific and preferably precalculated torsional vibration behaviour setting.

www.jbj.co.uk/couplings.html#flender 14 #DriveLineHarmony ELPEX-S Series Design & Configurations Highly Flexible Couplings Fail-safe device of ELPEX-S coupling G_MD10_XX_00023 The ELPEX-S coupling can also be designed with a fail-safe device. If the rubber disk element fails, the coupling can continue operating in emergency mode for a short time. This option is frequently required e.g. in the case of marine drives. If the rubber disk element fails, cams transmit the torque from the inner and outer parts of the fail-safe device. In normal operation the torsion angle of the rubber disk element is smaller than the gap between the cams, so there is no metal tometal contact. In the case of machines which excite torsional vibration, it is highly recommended carrying out a torsional vibration calculation or measuring the coupling load occurring in the drive. Function The ELPEX-S coupling's transmission characteristic is determined essentially by the rubber disk element. The torque is transmitted positively between the rubber disk element and the outer flange. The outer flange can be bolted to e.g. a diesel motor or compressor flywheel. Coupling selection The ELPEX-S coupling is especially suitable for rough operating environments. An application factor lower than that in the chapter introduction is therefore sufficient for all applications.
