#PROGRESSION~N-Eupex Torsionally Flexible Couplings www.jbj.co.uk/couplings.html#flender 39 #DriveLineHarmony Type DK couplings in the size range from 68 to 225 are appropriate for long and trouble-free operation, particularly for pump applications, because they enable compensation for large shaft offsets as a consequence of thermal expansion, for example. Due to very low restoring forces, the coupling provides a smooth solution in difficult and demand-ing cases. Moreover, theATEX coupling is certified, so it is suitable for use in potentially explosive areas. » 2.2 Split hub With the split hub, assembly and disassembly are simple and inexpen-sive, requiring only that the two half shells be connected or separated. The coupled drive and work machines do not have to be moved. In comparison with the conventional hub design, this saves up to half of the time required. For example, to exchange a pump, only the locating screw of the respective half shells has to be loosened. Then the hub can be easily removed. After the new pump is mounted or attached, the two half shells of the split hub can be simply placed in position and screwed together. The same is true for exchanging the elastomer elements, whichmust be replaced at specified intervals depending on operating behavior and wear condition. Anew feature on the market is that the half shells in the parallel keyway are split. When the clamping screws are tightened, the half shells are centered above the parallel key, which guarantees that the halves are positioned properly with respect to each other. A positive side effect here is that the keyed joint is constructed so that there is no backlash. » 2.3 Comparison of the N-EUPEXH and the N-EUPEXDK
