1. Technical data

The following lists of technical data contain the most important details of the coupling. These data
and the contractual agreement for the coupling determine the limits of its use according to the terms
of the contract.

The nominal torques TKN shown in the following lists are valid for:

• Continuous operation up to 24 h

• Shock loads of up to twice the nominal torque are allowed up to five times per hour on starting
or during operation.

• Operation within the stipulated alignment

• Operation within a temperature range from -20 °C up to +280 °C (ambient temperature resp.
shaft end temperatures)

Attention ! In order to ensure continuous, trouble-free operation, the coupling

has to be selected with a service factor, adequate to the application.
In case of changes in operating conditions (power rating, speed,
changes on driver or driven machine) re-examination of the design
is urgently necessary.

2. General information

2.1 General

These operating instructions should always be kept accessible near the coupling.

Only exact knowledge of the operating instructions ensures trouble-free coupling operation.
Therefore, it is in the interest of our customers that these instructions are read, understood and
in all aspects observed by personnel responsible for transport, assembly and operation.

Note: We cannot be held responsible for damages and operating hold-ups, resulting from failure
to comply with the operating instructions.

The “coupling” dealt with in these instructions, has been designed for stationary applications in
general mechanical engineering.

Possible applications for couplings of this series are e.g. waste water treatment, dredgers,
chemical industry, printing machines, iron and steel industry, conveyors, hoisting equipment, food
industry, paper machines, pumps, cable railways, ventilators, compressors, cement industry etc.

The coupling is designed only for the application range stated in section 1 “Technical data”.
Deviating operating conditions necessitate a new contractual agreement.

The coupling described herein, corresponds to the state of technology at the time of going to press.

In the interest of further development, whilst maintaining the essential characteristics, we reserve
the right to make changes, which are deemed to increase its capacity and safety.

The copyright on these operating instructions remains with Flender AG.

3. Safety information

3.1 Safety notes for the user

• The coupling has been designed according to the state of technology and is supplied in a safe
to operate condition. Unauthorized modification, which interfere with the operational safety are
not permitted. This applies also to guarding devices, which have been put up against
unintentional contact.

• The coupling is to be installed and operated only within the scope of conditions laid down in the
supply contract.

• The customer 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 environment
protection 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 safeguarded
against 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 the coupling.

• The driver is to be switched off at once, if, during operation, any changes such as changed
running noise, can be noticed on the coupling.

• The coupling is to be protected by appropriate protecting guards against accidental touching.

• When the coupling is incorporated in machines or equipment, the manufacturer of the machine
or equipment is obliged to include all instructions, notes and descriptions of these operating
instructions in his operating instructions.

3.1.1 Marking of safety notes in the operating instructions

Any important instructions which refer to safety and operational protection, have been marked by:

This symbol points to safety measures, which must be followed to avoid

personal injuries.

Attention ! This symbol refers to safety measures which must be observed to avoid
damage to the coupling.

Note! This note refers to general operating instructions, which should be

specially noted.

4. Transport and storage

4.1 Extent of supply

The extent of supply is listed on the transport documents. Its completeness should be checked on
delivery. Possible transport damage and/or missing parts should be reported immediately in
writing. After consultation with Messrs. Flender an expert should be called in.

4.2 Transport

Subject to transport route and size, the coupling is packed differently. If not specially agreed in the
contract, the packing corresponds to guide lines HPE. Symbols on the packaging should be noted.
They have the following meaning:

Top Fragile Keep dry Sensitive Centre of Do not use Secure

to heat gravity hook here

Attention ! Make sure to use suitable lifting gear.

4.3 Storage

4.3.1 Storage of coupling parts

The coupling is supplied with a protective coating and can be stored for up to 6 months, indoors
at a dry location. In case longer storage is intended, a corresponding long-term conservation is
necessary (refer to Flender).

4.3.2 Storage of plate packs

4.3.2.1 General information

Properly stored plate packs remain unchanged in their characteristics. Storage under unfavourable
conditions and improper handling will have a negative influence and a change of physical properties
will result. These changes can come about through reaction to oxygen, ozone, extreme temperatures
or damp.

4.3.2.2 Store

The storage place should be dry and dust-free. The plate packs are not to be stored together with
corrosive chemicals, acids, alcaline solutions etc.

Attention ! Damp storage places (relative humidity above 65%) are unsuitable.
Care should be taken that no condensation develops.

5. Technical specification

5.1 General description

Hub Plate pack Spacer Plate pack Hub

Octagonal plate pack

ARPEX couplings are all steel couplings. The plate packs are placed between flanges of coupling
parts and spacer and alternately bolted with them.

Individual thin steel plates are assembled on bushings and are pressed tightly together by an
inserted, internally bevelled, retaining ring. The retaining ring is fastened by the expanded end of
the bushing, which fits snugly against it. As all joints are built-up like this, the plate pack forms a
compact unit.

By this arrangement of plate packs, the ARPEX coupling is torsionally stiff and torque is transmitted
without backlash.

ARPEX couplings of series ARS-8 size 251-8 to 722-8 have octagonal plate packs (see illustration).
Collar bolts with collar nuts connect plate packs with spacer- and coupling part flanges.

By virtue of the modular design concept, ARPEX couplings can be assembled almost at random.

The size identification of the coupling is on the outside diameter (da) of coupling flange in mm. This
identification is complemented by a preceding combination of letters, which specify the coupling
components.

6.1 Information on machining finish bores, axial safeguarding, setscrews, balancing

6.1.1 Finish bores

• Remove rust preventive coating from coupling parts.

Observe manufacturer’s instructions regarding handling of solvents.

In order to machine finish bores components have to be carefully aligned. Limits for concentric and
offset mislignment are listed in table 6.1. Parts have to be held at the planes marked thus ( ).

Attention ! The max. permissible bore diameters apply to drive type fastenings
without taper action according to DIN 6885/1 and must not be
exceeded under any circumstances.

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.

Disregarding these notes can cause damage to the coupling. Flying

metal fragments can cause serious personal injuries!

order to keep the clearance in the shaft hub connection as low as
possible, depending on utilization of the tolerance bands and, on
the other hand, to limit hub stressing arising due to the interference
within the permissible levels. Non-compliance may endanger the
shaft-hub connection.

Disregarding these notes can cause damage to the coupling. Flying

metal fragments can cause serious personal injuries!

6.1.1.1 Keyways

Keyways have to be machined to suit the existing keys. For keyways, the tolerance band of hub
keyway width ISO P9 has to be kept to.

6.1.2 Axial safeguarding

A setscrew or endplate can be used for axial safeguarding of coupling parts. If end plates are to
be used, 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 the keyway.

Table 6.3: Setscrew allocation

The following guide lines should be observed!

The setscrews are to be located at the centre of the hub core, as shown in above illustration. If this
is not practical, please note that the clearance distance (e) to the setscrew is to be at least
M x 1,5.

Hexagon socket setscrews with cup point according to DIN 916 should be used.

The setscrew length should fill the threaded hole but not project
above the hub (L min = M x 1,2)

6.1.4 Balancing

Rough drilled couplings resp. rough-drilled coupling parts are supplied in an unbalanced condition.
For these components it is recommended that they are balanced, subject to their intended use, after
finish boring (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 be
removed to a minimum, a rather large equalizing radius should be chosen.

Finish bored couplings or coupling parts are supplied in a balanced state according to customer‘s
specification.

6.2 General information on assembly

When assembling , the safety instructions of section 3 should 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
and subsequent 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 the coupling or coupling parts, as this will have a negative
influence on the mechanical properties of the coupling.

Disregarding these notes can cause damage to the coupling. Flying

metal fragments can cause serious personal injuries!

6.3 Mounting of coupling parts (shaft-hub connection with key)

Prior to starting, finish bores and surfaces for spacer rings and nuts resp. close fitting bolts (subject
to assembly procedure, see sect. 6.10) have to be thoroughly cleaned and rust protection removed.
The same applies to shaftends.

Observe manufacturer’s instructions regarding handling of solvents.

Attention ! The coupling parts have to be mounted using suitable equipment,

so as to avoid damaging any shaft bearings through axial mounting
force. Use suitable lifting gear. Distance ring

Shaft ends should not protrude over hub inside faces. If neces-
sary, place spacers or distance rings to bridge the gap between
coupling and shaft shoulder. Axial safeguarding by setscrew or
endplate.

Attention ! Tighten setscrews only with hex. key according to DIN 911,
without extention pipe.

Disregarding these notes can cause damage to the coupling. Flying

metal fragments can cause serious personal injuries!

For hubs with key connection it is recommended to warm the coupling hubs to max. 150 °C, this
will facilitate mounting.

Take care not to get burned by hot components.

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
the endplate if applicable resp. loosen setscrew. With the aid of a three-armed puller resp. by
placing a pulling device in the threaded holes (only in existence if demanded), remove the hub from
the shaft.

In case of a tight fit, warm the hub uniformly with a burner and carefully pull the hub with a pulling
device from the shaft.

Take care not to get burned by hot components!

Check disassembled components carefully before reuse or return them, if necessary, to Flender
for repairs.

6.5 Shrink connections

6.5.1 Assembly

Cylindrical shrink connections are joined by heating the outer part. To avoid premature binding,
joining should be carried out speedily in a draught-free space.

Attention should be paid to a short transport distance!

6.5.1.1 Mounting aids

• Hot air oven or ring burner

• Crane with rapid lowering facility (for vertical shaft)
• Cleaning agents, solvents, brushes, rags

BA 8702 EN 06.98 Page 15 of 32

6.5.1.2 Preparation for shrinking

• Parts should be visually checked

Particularly noting the following points:
- chamfer on shaft and hub bore
- shrink fit surfaces without any damage
- undamaged threaded connections for hydraulic implements.

• Remove preserving coat from parts to be joined with solvent

Observe manufacturer’s instructions regarding handling of solvents.

• Check penetrability of oil channels and lengths of threads of thread connections.

• Heat hub uniformly to the specified temperature.

Take care not to get burned by hot components!

6.5.1.3 Shrinking process

• Preferred shaft position, if possible, is vertical.

• Locate heated hub without tilt, taking note of the leading-in chamfer.
• Lower hub without interruption down to the shoulder, taking care that no tilting occurs.
• Leave parts to cool slowly to room temperature
• parts can stressed after approx. 24 hours.

Take care not to get burned by hot components!

6.5.2 Disassembly of shrink connections

To disassemble a coupling hub with a cylindrical shrink fit, the plate packs and the spacer have to
be disassembled first.

When disassembling in cold surroundings, the shrink connection should be slightly warmed up.

6.5.2.1 Ungraded shaft end

Depending on the length of the coupling hubs, there are one or more oil grooves. The oil must be
pressed into the shrink fit with the aid of one or more pumps, subject to the number of oil grooves.
The axial movement is realized with the help of a separate hydraulic press or mechanical puller.

6.5.2.2 Graded shaft end

The coupling hubs are furnished with at least one oil groove. A motor driven pump must be installed
at the transition from the smaller to the bigger diameter of the shaft, due to the large amount of oil
which is needed in a short time. A hand-operated pump is sufficient for all other oil connections.
The axial movement is caused by the pressure effect at the grade.

6.5.2.3 Viscosity of pressure oil

Under normal temperature conditions thin-bodied, pure mineral oil with a viscosity of 6 to 10°E at
50°C serves best as pressure oil.

However, should oil escape in masses, so that the pressure cannot be held on disassembly, the
use of more heavy-bodied oil is possible.

Page 16 of 32 BA 8702 EN 06.98

6.6 V-supports

Plate packs of ARPEX couplings are axially flexible and thus cannot support the weight of a spacer
in a vertical application. Support plates are optionally available, which direct the spacer weight as
an axial thrust force to the machine bearing, without straining the plate pack.
For applications of this type, spacers and connecting pieces are fitted, fully functional, at the factory.
The support plates are adapted and fitted to suit the coupling combination.

6.6.1 Assembly

When assembling a N-hub, the factory fitted support plate has to be removed by unscrewing the
three studscrews with an Allan key. The hub is then mounted on the shaft end as described in
section 6.3.

After mounting, reassemble the support plate in the hub, locate it properly and screw in the three
studscrews. Take care that the support plate seating is flat.

Disregarding these notes can cause damage to the coupling. Flying

metal fragments can cause serious personal injuries!

Now the plate pack is positioned on the hub face and the spacer with the factory fitted support plate
is located on the lower support plate; after this, the second plate pack and close fitting bolts are
inserted and assembled (see section 6.10 f).

6.6.2 Disassembly

Remove spacer and plate packs in reverse order. Unscrew the three studscrews and with two
forcing screws in the support plate, lift it out of the recess. When replacing plate packs, check the
V-support plates and renew them if necessary.

6.7 F-flange fastening

6.7.1 Condition on delivery

F- flanges are supplied, subject to agreement, as single parts or ready assembled with a spacer.

6.7.2 Assembly

Before assembling, clean coupling parts carefully with the help of a suitable solvent.

Observe manufacturer’s instructions regarding handling of solvents.

• Check recesses and contact faces of F-flanges for possible damage and rework them if
necessary.
• Take great care in making recess connections.
• The connecting bolts have to be tightened evenly one after the other with the specified torque
(see table 6.4), being careful that the recess connection is not tilted.

6.8 Assembly of summation balanced couplings

Couplings which are summation balanced, have a 4-digit number stamped on each component

6.10 Fitting the plate packs

6.10.1 Size 251-8 to 722-8 / Rotation angle method

6.10.1.1 Preparatory measures:

• Apply lubricant (ATEC special paste) to the contact faces of

the nut and the bolt head and the thread of the fitting bolt. This
lubricant is included in the scope of a plate pack supply. Bolt
the plate pack alternately together with the coupling
components, so that the rings (item 1, Fig. I) contact the
ARPEX flange (item 2). Preferably tighten the nuts so that they
contact the flange (Fig. I). If this is impossible for space
reasons, assembly the other way round is also possible.

• The tightening torque for the bolts must be applied to the nuts
Fig. I
and the bolt head be secured against turning. This protection
against turning must be supported on the flange to which the
plate pack is fastened. Tighten the nuts as follows:

6.10.1.2 Pretensioning of fitting bolt

The following procedure is recommended:

)
• Tighten the nuts consecutively using torque T0 (see table 6.5 α/2

Here, also, the same procedures apply as described

under 6.10.1. Radial flange

In addition, the following should be noted:

The plate pack has to be fastened to the coupling parts

such that the radial flange of the plate pack sits close to
the flange of the coupling part, as otherwise the proper
function of the coupling cannot be guaranteed.

Non-observance of these in-

structions can impair the pro-
per function of the coupling.

6.12 Alignment

The couplings can compensate for misalignment of shafts to be connected up to the data listed in
6.13. The radial and angular misalignments of shaft ends is to be kept as small as possible.

Couplings featuring two plate packs can accomodate axial, radial and angular misalignments.
Couplings with only one plate pack, accept just angular and axial misalignment.

On aligning machine parts, use a caliper gauge to measure gap "S1" (see illustration) between
coupling flanges at several measuring points. If the measured flange gaps are within the value range
S1 min/S1 max (see table 6.6), then the alignment is sufficiently good.

S1 = Gap of coupling flanges

S1 min = see table
S1 max = see table
M = Measuring point

Attention ! The assembly misalignment values must not exceed values for
S1 min and S1 max (table 6.6). In order to have misalignment
reserves for the operating process, it is advisable to align the
couplings such that the assembly misalignment is smaller than
stated below (see also sect. 6.13 f).

6.13 Possible misalignments

Misalignments of coupling parts relative to each other can occur from inaccurate alignment on
installation or can be caused by operating factors (heat extension, shaft bending, machine frame
too weak etc.).

Radial misalignment ∆Kr / Angular misalignment ∆Kw Axial misalignment ∆Ka

S - ∆Ka

∆Kr

∆Kw

L S + ∆Ka

Table 6.7 lists perm. misalignments in angular and at the same time, axial direction, whereby values
for axial misalignment refer to 1 plate pack.

The listed values are the total allowable misalignments which are allowed to occur during operation;
misalignments which occurs during the assembly process must be considered appropriately.

Permissable radial misalignment depends on the allowable angular misalignment and on center
distance of plate packs.

∆Kr = tan ∆Kw × L

L = center distance of plate packs

L = S8 - S1

Example for finding the permissible misalignment:

Required:
Perm. misalignment values for an ARPEX coupling type ARS-8 NHN 251-8 with a shaft distance
of S8 = 1000 mm.

a) Allow. angular misalignment = 0,4° at ∆Ka = 0 mm

Allow. axial offset = ± 2,1 mm (2 plate packs = 2 x 1,05 mm) at ∆Kw = 0°

b) Allow. axial misalignment at ∆Kw = 0,2° = ± 1,06 mm (2 plate packs = 2 x 0,53 mm)

The corresponding allow. radial misalignment at an angular misalignment of 0.2° is calculated

as follows:

Center distance of plate packs L = S8 - S1

= 1000 mm - 25 mm = 975 mm

∆Kr = tan (0,2°) x 975 mm = 3,40 mm

7. Putting into service

7.1 Before operating

Check all bolt connections and retighten them if necessary. Alignment and gap dimension S1
should also be checked and corrected if necessary (see table 6.6 and 6.7). Then mount the
coupling guard, protection against unintentional contact.

Disregarding these notes can cause damage to the coupling. Flying

metal fragments can cause serious personal injuries!

8. Operation

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

Attention !
must be stopped at once. Determine the cause of trouble with the
aid of the trouble-shooting check list (sect. 9) which features
possible sources, their causes and proposals to eliminate them.
In case, the cause cannot be found resp. if there is no possibility
to remedy the trouble with own resources, we recommend calling
for a service engineer from one of our service depots (sect. 11).

9. Failures - causes and remedies

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. Different
operating behaviour should be seen as a fault, which has to be remedied promptly.

Before beginning any maintenance activities, repairs or other

work, the operator has to ensure that the complete drive has
stopped. The driver has to be secured against unintentional
starting; otherwise we refer to the particular health and safety
requirements for the installation.

10. Maintenance

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.
Should individual plates or whole strands be broken, then the particular plate pack has to be
replaced; in these cases, check also the coupling flanges for damage.

Any further maintenance work is not necessary.

10.2 Replacing plate packs

Original ARPEX plate packs should only be used as replacement, to guarantee proper torque
transmission and trouble-free function.

Note! As a rule, replacing plate packs is possible without the necessity to shift
coupled drive members. Exceptations are combinations with F-flanges
and special designs.

For reassembly, carefully note instructions of section 6 “Assembly” and section 7 “Putting into
service”.

11. Stocking of spare parts, addresses of service centres

Storage of important spare and wearing parts at the site is an essential requirement for operational
availability of the coupling.

When ordering spare parts, the following data has to be given:

Number of pieces, name of parts, size ( provided it is available, state also DRG. no. and
position of spare part on the spare parts list.)

If coupling parts are required with finish bore and balanced, specify the following:

Finish bore, fit, keyway and balancing quality

Example of an order: 1 pc. ARPEX hub, series ARS-8, size 285-8 with bore 100 H7 and
keyway according to DIN 6885-1, single part dynamically
balanced G 2.5 - after keywaying, speed 1000 rpm

1 pc. ARPEX plate pack, series ARS-8, size 285-8 complete.

We can only guarantee original spare parts supplied by us.

Attention ! We expressly draw client’s attention to the fact that spare parts and
accessories not supplied by us, have not been checked and
released by us. Their assembly and/or use can possibly alter
design characteristics negatively and thereby impair the active
and/or passive safety. Flender AG excludes any liability and
guarantees for any damage which results from the use of non-
original spare parts and accessories.

Please note that for individual components special manufacturing and supply specifications
frequently exist and that we always offer spare parts according to the state of technology and latest
legal requirements.
