Backlash-free Servo-insert Coupling Assembly InstructionsInstallationClean and degrease both shaft surface andcoupling hub bores. Re-check shaft diametersand coupling bores for proper tolerances.As a standard, the boreholes are equippedwith a fitting in accordance with ISO-H7.For the shafts, we recommend an transition,e.g. H7/g6. When selecting other shaft fitting,the fitting should not exceed a maximum of0.01 - 0.05 mm.Slide a coupling hub onto each shaft andproceed to torque the screws of one clampring or shrink disc after checking axial dimensions.Refer to the technical data to assurecorrect screw tightening torque.Firmly press elastomer spider into one of thetwo hubs. Because of the interference fit,the force necessary to install the spider maybe quite high, therefore a PU tolerant greasesuch as Vaseline may be applied to easeassembly. The edges of the spider and thejaws of the coupling hubs are both chamferedto ease assembly.Raised contact points visible on the front andback side of the elastomer spider help maintainproper spacing between the two hubsassuring electrical isolation and full angularmisalignment capabilities.Carefully push the coupling hubs togetherwhile maintaining the necessary spacing,tighten the screws of the remaining clampring or shrink disc to the recommended torque.The function of the gap is to prevent thecoupling hubs from restraining the axial movementof the spider. This ensures optimumlife of the coupling and spider.coupling hubWhile mountinghubspiderelastic deformationelastomerspiderhubhubhubspiderraisedcontact pointsBacklash free after finalassembly preloadedhubspiderEhub®DIST.

Therefore, theflexible spider needs to be precompressedfor proper seatingduring the assembly procedure.The amount of pre-compressionvaries widely depending on theshore harness of the spider, thesize of the coupling and the machiningtolerances. A light forceis necessary to pre-compressthe torsionally soft spiders whilea large force is required to precompressa torsionally stiff spider.TkN – Nominal Torque of coupling(Nm): Continuous torquewhich can be transmittedthroughout the entire speedrange, taking into considerationoperational factors such as ambienttemperature and torsionalstiffness.Tkmax – Maximum Torque ofcoupling (Nm): Torque to betransmitted 1 x 10^5 times asa peak load or 0.5 x 10^4 timesas an alternating load during theentire life of the coupling takinginto consideration factors suchas temperature, torsional stiffnessand shock loading.Type Servoinsert5791419242838424880929880929864809298648092986480929864929864929864929864929864929864ShorescaleMax. speed (min -1 ) for typeDK/GSADSADS/R EK/GS ASS/A ASS/A-P DMK/ADSDXK/ADSAAAAAADAAADAAADAAADAADAADAADAADAAD38000 4750027000 3400019000 2400013000 16000 2540010000 12000 190007000600050004000360085001380011700955080507200318002380017300147001190010000910011450895070006000500040000,30,50,90,71,22,02,41,835647,512,5165101721356075951602001903254052654505603105256551) Dynamic torsional stiffness at 0.5 x TkNDynamic balancing is required for speeds exceeding V=30m/sTorque (Nm)TkNTkmax0,61,01,71,42,44,04,83,66101281525321020344270120150190320400380650810530900112062010501310Statictorsionalstiffness3,25,28,38,614,323341731517460115172234340570860124014302060298022903440435045807160105406300192002758078502237036200Dynamictorsionalstiffness1016252643691035295155224180344513702103017202580372042966189893468761031413050137522148631620243055707170258059308274Axialstiffness(Nm/rad) (Nm/rad) 1) (Nm/mm)82154296114219421630125262518769153336654856582112020102930148025603696178032004348235044006474243055707270258059308274®DIST.
