2. General information
2.1 Introduction
These operating instructions are constituent part of the coupling delivery and should always be keptaccessible near the coupling.
All persons involved in the installation, operation, maintenance and repair ofthe coupling must have read and understood these Operating Instructions andmust comply with them at all times. We accept no responsibility for damage ordisruption caused by disregard of these Instructions.
The “couplings“ dealt with in these Operating Instructions, have been designed for stationaryapplications in general mechanical engineering. The coupling serves to transmit power and torquebetween two shafts or flanges connected by this coupling.
The coupling described in these Operating Instructions, corresponds to the state of technicaldevelopment at the time of going to press.
In the interest of further development, whilst maintaining the essential characteristics, we reserve theright to make changes on single modules and accessory parts, which are deemed to increase itscapacity and safety.

� The coupling is to be installed and operated only within the scope of conditions laid down in the supplycontract.The coupling is designed only for the application range stated in the product catalogues (seechapter 1. of these Operating Instructions ”Technical data” and table 1.1). Any other or furthermoreuse or deviating operating conditions be considered as ”non-intended use” and necessitate a newcontractual agreement.For damages which result from this only the user/operator of the machine/application assumesliability.
3.2 Fundamental duties
� The operator has to ensure that all personnel engaged in assembly, operation, care and maintenance,have read and understood these operating instructions and that they strictly observe all points to:
– avert danger to life and limb of users and third parties
– safeguard the operational safety of the coupling
and
– exclude downtime and environmental damage through wrong handling.
� The relevant regulations and instructions concerning health and safety at work, and environmentprotection have to be observed for transport, assembly and disassembly, operation and maintenance.
� The coupling is to be operated and maintained only by authorised and trained personnel.
� All work has to be carried out carefully and from the point of view of “safety”.
� Any work on the coupling has to be carried out whilst it is at rest. The driver is to be safeguardedagainst unintentional starting (e.g. by locking the key switch or removing fuses in the mains supply).A notice should be placed at the start-up location which says that work is being carried out on thecoupling.
� The coupling is to be protected by appropriate protecting guards against accidental touching. Theprotecting guards must not impair the function of the coupling.
For use in hazardous areas the protecting guards must be conform to type ofprotection IP2X at least.
� The driver is to be switched off at once, if, during operation, any changes can be noticed on thecoupling.

5. Technical description
5.1 General description
Hub HubPlate pack
SpacerPlate pack
Hexagonring plate pack
Octagonside bar plate pack
Hexagonside bar plate pack
ARPEX couplings are all steel couplings. The plate packs are placed between the flanges of thecoupling parts and alternately bolted with them.
Individual thin steel plates are assembled on bushings and are pressed tightly together by inserted,internally bevelled, retaining rings. The retaining rings are fastened by the expanded ends of thebushings, which fit snugly against it.
Due to this arrangement at ring-disc-design the plate pack forms a compact unit. Side-bar-plate-packsare composed of single side bar discs which are beaded together in disc-strands which form, annularlycompounded, the plate pack.
Due to this arrangement of plate packs, the ARPEX coupling is torsionally stiff and torque is transmittedwithout backlash. In axial and radial direction the coupling remains flexible and is able to compensateaxial, radial and angular misalignments of the connected machines.
Depending on the coupling series collar bolts and collar nuts or conical bolt-units connect the platepacks with spacer- and coupling part flanges.
The size identification of the coupling defines the outside diameter (da) of coupling flange in mm as wellas the design of the plate pack (”-6” = hexagon). This identification is complemented by a precedingcombination of letters, which specify the coupling components.
Example: ARS-6 NHN 255-6Coupling with 2 hubs (N) and 1 H spacer (H) size 255 with hexagon plate pack ofseries ARS-6

BA 8704 EN 11.05
5.2 Marking of the coupling parts according to Directive 94/9/EC
Couplings, which are assigned for use in hazardous areas, must show thefollowing marks e. g. at the hub core diameter of one of the couplingcomponents:
FLENDER AG �� 2G T2/T3/T4/T5/T6 –40°C�Ta�230/150/85/50/35°C
D-46393 Bocholt �� 2D T 120 °C –40°C�Ta�70°CARPEX <year of manufacture> � M2
All other coupling components must be marked with (at small componentsonly the packing material is marked, if necessary).
5.3 Operating conditions
Marked couplings and coupling parts as desribed in Item 5.2 ”Marking of thecoupling parts according to Directive 94/9/EC” are suited for the operatingconditions defined in Directive 94/9/EC.
� Equipment group II (use above ground) of category 2 and 3 for areas wherethere are explosible gas, vapour, mist, air mixtures as well as for areas wheredust can form explosible atmospheres.
Depending on the associated temperature class the following maximumambient temperature in the direct vicinity of the coupling, resp. maximumsurface temperature of the coupling is permissible.

6. Assembly
Note: The instructions of section 3, ”Safety notes” must be observed.
Couplings and coupling parts which will be operated in hazardous areas inconformity with Directive 94/9/EC, are delivered fundamentally only finishbored by the manufacturer.
For couplings which will not be operated in hazardous areas in conformity with Directive 94/9/ECFLENDER also delivers unbored or prebored coupling parts at customer’s request. The necessaryrefinishing must be carried out in strict compliance with the following specifications and with particularcare!
Responsibility for carrying out the refinishing is borne by the orderer.FLENDER can accept no guarantee claims arising from unsatisfactoryrefinishing!
The specified tightening torques in chapter 6 (table 6.2, 6.3 and 6.4) must beabsolutely kept. Deviating tightening torques may result in accelerated wear ofthe plates and damage of the coupling.
Non-observance of the instructions stated in this chapter may result inbreakage of the coupling. Flying metal fragments can cause serious personalinjuries!
A damaged coupling becomes an explosion hazard. Operation of the couplingwith damaged coupling components in hazardous areas in conformity withDirective 94/9/EC is inadmissible.
6.1 Information on machining finish bores, axial safeguarding, set screws, balancing
6.1.1 Finish bore
Remove rust preventive coating from coupling parts.
Observe manufacturer’s instructions regarding handling of solvents.
When machining the finished bore the parts must be carefully aligned. For the permissible radial andaxial run1-outs, refer to DIN ISO 286 Basic Degree of Tolerance IT7.The parts must be mounted on the marked faces ( ) (see Fig. 6.1).

BA 8704 EN 11.05
The max. permissible bore diameters (see chapter 1 ”Technical data”) apply todrive type fastenings without taper action according to DIN 6885/1 and must notbe exceeded under any circumstances. The finished bores must be 100 %checked with suitable measuring equipment.
If instead of the planned drive type fastening other shaft- hub connections (e.g. splined hub profiles,tapered or stepped bores, stressed type fastenings with taper action) are to be used, consult FLENDER.
For drive connections by keys, the following combinations of fit are specified (see table 6.1):

Table 6.1: Combinations of fit
Observation of fit combinations is necessary, on the one hand, in order to keepthe clearance in the shaft hub connection as low as possible, depending onutilization of the tolerance bands and, on the other hand, to limit hub stressingarising due to the interference within the permissible levels. Non-compliancemay endanger the shaft-hub connection.
6.1.1.1 Keyway
Keyways have to be machined to suit the existing keys. For keyways, the tolerance band of hub keywaywidth ISO P9 has to be kept to.
Caution!

6.1.2 Axial safeguarding
A setscrew or endplate must be used for axial safeguarding of coupling parts. If end plates are to beused, contact FLENDER with regard to the recessing of coupling parts.
6.1.3 Setscrews
To avoid damaging the shaft, the setscrew bore should be machined over thekeyway.In exceptional cases the setscrew has to be displaced by 180° according to thekeyway, if due to the bore and hub core diameter too little steel material remainsbetween keyway and hub core (e. g. series ARS-6 size 78-6).
The following guide lines should be observed:
The setscrews are to be located at the centre of the hubcore (see fig. 6.2). If this is not practical, please note that theclearance distance (e) to the set screw is to be at least M x 1.5.
Hexagon socket set screws with cup point according to DIN 916should be used.

Fig. 6.2: Bore for setscrew
The set screw length should fill the threaded hole but not project above the hub(Lmin. = M x 1.2).
6.1.4 Balancing
Rough drilled couplings resp. rough-drilled coupling parts are supplied in an unbalanced condition. Forthese components it is recommended that they are balanced, subject to their intended use, after finishboring (for this purpose, we refer to DIN 740, DIN ISO 1940 part 1).
Balancing is usually achieved by removing metal through drilling. In order to limit the material to beremoved to a minimum, a rather large equalizing radius should be chosen (see fig. 6.3).
Finish bored couplings or coupling parts are supplied in a balanced state according to customer’sspecification.

6.2 General information on assembly
Note: The instructions of section 3 ”Safety notes” must be observed.
Assembly is to be carried out with great care by skilled fitters.
Care should be taken, already at the planning stage, that adequate space is available for assembly andsubsequent maintenance work.
Adequate lifting gear should be on hand at the start of assembly.
Under no circumstances can any sort of welding work be allowed on thecoupling or coupling parts, as this will have a negative influence on themechanical properties of the coupling.
If lacquered couplings are used in hazardous zones, the requirements for theconductivity of the lacquer coating and the limitation of the thickness of theapplied lacquer coating in accordance with Guideline EN 13463 (Guidelines forthe avoidance of explosion hazards due to electrical charges) must beobserved. Where lacquer coatings have a thickness less than 200 �m, noelectrostatic charge is to be expected. Where lacquer coatings are thicker than200 �m, an electrostatic charge must be avoided, e.g. by cleaning the coupling.

6.3 Mounting of coupling parts (shaft-hub connection with key)
Before starting assembly the bore holes and the bearing surfaces of the rings, bushes, nuts and reamedbolts resp. tapered sleeves and bushes (see section 6.12 ”Assembly of the plate packs” resp. separateassembly instructions) must be recovered from dirt and all kind of rust-preventative such as paint, Tectyletc. The same applies to shaft ends.
Observe manufacturer’s instructions regarding handling of solvents
The coupling parts have to be mounted using suitable equipment, so as toavoid damaging any shaft bearings through axial mounting force. Use suitablelifting gear.
Shaft ends should not protrude over hub inside faces. If necessary,place spacers or distance rings to bridge the gap between couplingand shaft shoulder (see fig. 6.4). Axial safeguarding by setscrewor endplate.
Tighten setscrews only with hex. keyaccording to DIN ISO 2936, without extensionpipe.
For hubs with key connection it is recommended to warm thecoupling hubs to max. 150 °C, this will facilitate mounting.
Take care not to get burned by hotcomponents!
A mounting device will ease fitting hubs with transition fits and heated hubs on the lightly oiled shaft end.
Bar is threaded into shaft end; size of thread depends on available shaft diameter. Put a plate ofappropriate size over the threaded bar. By tightening the nut the hub moves onto the shaft (see fig. 6.5).

6.4 Disassembly of shaft-hub connection with key
To pull a coupling hub from the shaft, the plate packs have to be disassembled first. Then remove theendplate if applicable resp. loosen setscrew. With the aid of a three-armed puller resp. by placing apulling device in the threaded holes (only in existence if demanded), remove the hub from the shaft(see fig. 6.6 and 6.7).
In case of a tight fit, warm the hub uniformly with a burner and carefully pull the hub with a pulling devicefrom the shaft.
Take care not to get burned by hot components!
Check disassembled components carefully before reuse or return them, if necessary, to FLENDER forrepairs.

6.5 Shrink connections
6.5.1 Assembly
Cylindrical shrink connections are joined by heating the outer part. The shrinking temperature will becalculated by the manufacturer according to the corresponding order and can be taken from thesupplied coupling drawing.To avoid premature binding, joining should be carried out speedily in a draught-free space.
Attention should be paid to a short transport distance!
Remove the screw plugs from the thread connections of the hubs at gradedshaft ends during the joining process of the hubs. Reinsert the screw plugsafter completion of the joining process.
The joint surfaces must be absolutely clean and grease-free.
Observe manufacturer’s instructions regarding handling of solvents.
Take care not to get burned by hot components!
6.5.2 Disassembly
Depending on the length of the coupling hubs, there are one or more oil grooves. The oil must bepressed into the shrink fit with the aid of one or more pumps, subject to the number of oil grooves. Theaxial movement is realized with the help of a separate hydraulic press or mechanical puller.
Secure hubs axially! Danger of injury due to drop down of couplingcomponents.

Note the following procedure on assembly:
� Degrease shaft and hub bore.
Hub bore and shaft must be absolutely clean and grease-free.
Observe manufacturer’s instructions regarding handling of solvents.
� Loosen clamping screws slightly and pull clamping ring just a fraction off the hub, so that the clampingring is loose.
� Push hub on shaft.
� Tighten clamping screws evenly one after the other. Several turns must be made, until the clampingring fits snugly and evenly on the flange of the clamping resp. slipping hub. The clamp connection isready for use, when the tightening torque for clamping screws (quality 10.9), listed on page 22 intable 6.3 ”Tightening torques for connection and clamping screws”, has been reached and theclamping ring sits close against the hub flange.
Non-observance of these recommendations can impair the function of theclamping hub resp. slipping hub.Caution!

6.6.2 Disassembly
Loosen clamping screws evenly one after the other. Each screw should only be loosened by half arevolution per rotation. Free all clamping screws by 3 - 4 threads.
In case the clamping ring does not automatically come loose from the hub, additional forcing screws,depending on number of threaded holes (subject to size of coupling), have to be used on the ARPEXflange and evenly tightened, until the clamping ring comes loose. Before mounting the clamping ringagain, remove the forcing screws!
Subject to the size, clamping and slipping hubs of type 124 (see fig. 6.8) are already equipped withforcing screws in the clamping ring. Before mounting the clamping ring again, screw back the forcingscrews to their original position!
If the procedures described before are not successful at the bigger clamping hubs, oil has to be forcedinto the parting line between clamping ring and hub by high pressure pump; to remove thus the selfblocking of the clamping ring. For this purpose the high pressure hose of the pump is connected via theG 1/4” connecting thread on the outside diameter with the clamping ring (see fig. 6.10).
Before retightening the clamping ring remove the forcing screws and close the G 1/4” threaded hole withthe plug, supplied as part of the shipment.
If the clamping ring has been removed hydraulically, then the taper surfaces have to be cleaned toremove the hydraulic oil and greased again with Altemp Q NB 50 (Messrs. Klüber).
Observe manufacturer’s instructions regarding handling of solvents.
Dismounted clamping resp. slipping hub connections do not have to be further disassembled andregreased before retightening. But in case the cone faces are to be greased again, the above namedlubricant must be used.

Depending on the length, splitted spacers are supplied in pre-assembled, hand-tightened condition oras component parts.
6.8.1 Assembly of splitted spacers
� Before assembling, degrease the fitting bores and the bearing faces of the coupling parts carefully.
Fitting bores and bearing faces of the coupling parts must be absolutely cleanand grease-free.
Observe manufacturer’s instructions regarding handling of solvents.
� Internal and external recesses (see figure 6.12) resp. the fitting bores (see figure 6.13) as well as thebearing faces of the components of the splitted spacer have to be checked for possible damage andreworked if necessary.
� Before inserting the bolts, look for possible balancing markings (see figures 6.12 to 6.13). Atunmarked spacers the spacer halfs must be mounted in that way, that the fitting bores of the outerflanges lie opposite (see figures 6.12 to 6.13).
� Be very careful in fitting recess resp. fitting bolt connections.
� The connecting screws have to be tightened crosswise and evenly one after the other with thespecified tightening torque (see table 6.3 ”Tightening torques of connection and clamping screws”).
� Be careful that the recess connection is not tilted!

6.10 Assembly of summation balanced couplings
Couplings which are summation balanced, have a 4-digit number stamped on each component flangeOD (see figure 6.17 ”AAAA”). Take care on assembly, that only coupling parts are bolted together whichhave the same numbers on their flange OD. The components have to be arranged so that numbers arein one line, to be readable from one direction (see fig. 6.17). Only this arrangement guarantees therequirements!

7. Putting into service
Note: The instructions of section 3, ”Safety notes” must be observed.
7.1 Before operating
Before putting into service check all bolt connections and retighten them if necessary. Alignment andgap dimension S1 should also be checked and corrected if necessary (see corresponding tables in theassembly instructions of the different series).
For coupling types with pre-assembled plate packs it is absolutely required to check if the transitprotection (see detail X - figure 6.16) is completely removed.
Then mount the coupling guard, protection against unintentional contact.
For use in hazardous areas the protecting guards must be conform to type ofprotection IP2X at least.
Failure to observe these instructions may result in breakage of the coupling.Flying metal fragments can cause serious personal injuries!
A damaged coupling becomes an explosion hazard. Operation of the couplingwith damaged coupling components in hazardous areas in conformity withDirective 94/9/EC is inadmissible.
8. Operation
Note: The instructions of section 3 ”Safety notes” must be observed.
8.1 General operating data
During operation, pay attention to
� changing running noises
� suddenly occurring vibrations.
In case any irregularities are noticed during operation, the drive must bestopped at once. Determine the cause of trouble with the aid of thetrouble-shooting check list (see chapter 9).
The check list features possible sources, their causes and proposals toeliminate them.
In case, the cause cannot be found resp. if there is no possibility to remedy thetrouble with own resources, we recommend calling for a service engineer fromone of our service depots (see chapter 11).
Caution!

BA 8704 EN 11.05
9. Failures, causes and remedies
Note: The instructions of section 3, ”Safety notes” must be observed.
9.1 General
The following listed failures can only be clues in the search for any cause of faults.
In complex drive situations, all other components have to be included in the search.
During all operating phases, the coupling should run with low noise and without vibration. Differentoperating behaviour should be seen as a fault, which has to be remedied promptly.
FLENDER will not be bound by the terms of the guarantee or otherwise beresponsible in cases of improper use of the coupling, modifications carried outwithout FLENDER s agreement, or use of spare parts not supplied byFLENDER.
When remedying faults and malfunctions, the gear unit must always be takenout of service. Secure the drive unit to prevent it from being started upunintentionally. Attach a warning notice to the start switch.Otherwise we refer to the particular health and safety requirements for theinstallation.
9.2 Possible failures
Störungen Ursachen Beseitigung
Sudden change in noiselevel and/or suddenlyoccuring vibrations
Change in alignment Stop drive
Remedy reason for change in alignment(e.g. tighten loose foundation bolts)

BA 8704 EN 11.05
9.3 Incorrect use
Experience has shown that the following faults can result in incorrect use of the ARPEX coupling. Inaddition to observing the other instructions in these Operating Instructions, care must therefore betaken to avoid these faults.Directive 94/9/EC requires the manufacturer and user to exercise especial care.
Failure to observe these instructions may result in breakage of the coupling.Flying metal fragments can cause serious personal injuries!
Through incorrect use the coupling may become an explosion hazard.
Incorrect use of the ARPEX coupling may result in damage to the coupling.
Coupling damage may result in stoppage of the drive and the entire system.
9.3.1 Possible faults when selecting the coupling or coupling size
� Important information for describing the drive and the environment will not be communicated toothers.
� System torque too high.
� System speed too high.
� Application factor not correctly selected.
� Chemically aggressive environment not taken into consideration.
� The ambient temperature is not permissible.
� Finished bore with impermissible diameter resp. impermissible fit classification (see chapter 6).
� The transmission capacity of the shaft-hub connection is not appropriate to the operating conditions.
9.3.2 Possible faults when installing the coupling
� Components with transport or other damage are being fitted.
� When mounting coupling parts in a heated condition, this parts are being excessively heated.
� The shaft diameter is outside the specified tolerance range.
� Coupling components have been interchanged.
� Prescribed tightening torques resp. rotation angles are not being adhered to.
� Alignment or shaft misalignment values do not match the specifications of these operating orassembly instructions respectively.
� The coupled machines are not correctly fastened to the foundation, so a shifting of the machines e.g.through loosening of the foundation screw connection is causing excessive displacement of thecoupling parts.
� ARPEX plate packs are not installed correctly (see assembly instructions of each series).
� The coupling guard used is not suitable for operation within the meaning of the explosion protectionrequirements or according to Directive 94/9/EC.
� Operating conditions are being changed without authorisation.

9.3.3 Possible faults in maintenance
� Maintenance intervals are not being adhered to.
� Original ARPEX plate packs are not being used.
� Damaged ARPEX plate packs are being used.
� Use of ARPEX plate packs, which are not conform with the technical specification according to theapplication.
� Leakage in the vicinity of the coupling is not being identified and as a result chemically aggressivemedia are damaging the coupling.

BA 8704 EN 11.05
10. Maintenance
Note: The instructions of section 3, ”Safety notes” must be observed.
Any work on the coupling has to be carried out whilst it is at rest.The driver is to be safeguarded against unintentional starting (e.g. by lockingthe key switch or removing fuses in the mains supply). A notice should beplaced at the start-up location which says that work is being carried out on thecoupling.
10.1 General
ARPEX couplings should be visually checked corresponding to the maintenance schedules of the plant,but at least once a year. Special attention is to be paid to the condition of the plate packs. Shouldindividual plates or whole strands be broken, then the particular plate pack has to be replaced. In thesecases, check also the coupling flanges for damage.
Any further maintenance work is not necessary.
If the above specified maintenance instructions are not adhered to, a correctoperation within the meaning of the explosion prevention requirements andDirective 94/9/EC can no longer be guaranteed on the coupling.
Use in hazardous zones is then not permitted.
10.2 Replacing plate packs
Original ARPEX plate packs should only be used as replacement, to guarantee proper torquetransmission and trouble-free function.
Note: As a rule, replacing plate packs is possible without the necessity to shift coupled drivemembers. Exceptions are combinations with so-called B-hubs (hubs which areinserted into the spacer the other way round for space-reasons) and special designs.
For reassembly, carefully note instructions of section 6, “Assembly” and section 7, “Putting into service”.
