General technical descriptionThe ARCUSAFLEX® coupling is a highly flexible flywheel coupling with an axial plug-in facility. It provides a torsionally soft connection between an internal combustion engine and a driven machine.
The highly flexible torque transmission characteristic is achieved by a disc-shaped rubber element that is subjected to a torsional load and enables both, the absorption of high torsional vibrations and the compensation of major misalignments. For an optimum adaptation to the conditions of application three different kinds of vulcanisates are available: For application temperatures up to 80°C a natural/synthetic caoutchouc mixture as a standard version, up to 100°C a more heat resistant mixture and for higher application temperatures up to 130°C a silicone mixture.
The inside diameter of the rubber disc element is vulcanized directly to a taper hub or bolt-on sleeve. The toothed profile on the circumference of the element provides in service a virtually backlash-free, positive plug-in connection to the coupling flange.
The ARCUSAFLEX flywheel coupling series covers a torque range from 200 - 110000 Nm (corresponding to approx. 6500 kW at 1000 rpm). Element versions of different torsional stiffnesses are available for optimizing the torsional vibration range. The flange connection dimensions of ARCUSAFLEX couplings comply predominantly with the SAE J 620 and DIN 6281 standards. Other flange dimensions or overall lengths can be provided on request.
Shaft-to-shaft connections when required can be met by ARCUSAFLEX shaft couplings which consist of ARCUSAFLEX flywheel couplings of the standard design equipped with a second hub.
Type approvals by a number of leading classification societies are available. If required, couplings complete with fail safe devices can also be supplied.
ARCUSAFLEX® couplings comply to explosion protection according to ATEX 95. They are certified according to the directive 94/9/EC and may be used in hazardous locations (categories M2, 2 + 3).

TypesARCUSAFLEX type AC-T with taper bush
ARCUSAFLEX type AC...F2 with bolted hub
Taper bush
Flange
The ARCUSAFLEX® flywheel coupling type AC-T...F2 is equipped with a taper bush for shaft mounting. The rubber disc element is vulcanized directly to the taper hub. After completion of the assembly, a shrink-fit-like connection, free from backlash is established between the coupling hub with rubber disc element and the shaft.
Thanks to the use of commercially available taper bushes with a number of different bore dimensions, the need for finishing the bore and keyway of the coupling hub is omitted for the ARCUSAFLEX® coupling type AC-T. The torque, which can be transmitted, depends on the particular taper bush.
Advantage: Ease of assembly and disassembly with no need for special tools!
The ARCUSAFLEX® flywheel coupling type AC...F2 has the rubber disc element vulcanized to a bolt-on sleeve which in turn is bolted to a hub or similar component.
Advantage: Depending on the arrangement of the rubber disc element, two different mounting lengths can be achieved using one and the same coupling hub.

Element versions: WN = 55° Shore A; NN = 65° Shore A; SN = 75° Shore A; UN = 85° Shore A Due to the physical characteristics of the rubber materials the measurable rubber hardness is subject to a dispersion, which is defined according to DIN 53505 with ± 5° Shore A. Because of in-house manufacturing this dispersion of the shore hardness can be minimized. *) Continuous fatigue torque under reversing stresses ± TKW at = 10 Hz, for other frequencies fx apply TKW ∙ 1) Torsional stiffness for AC 2.7 on request

Technical noteThe technical data applies only to the complete coupling or the corresponding coupling elements. It is the customer’s/user’s responsibility to ensure there are no inadmissible loads acting on all the components. Especially existing connections, like bolt connections, have to be checked regarding the transmittable torque, if necessary other measures, e.g. additional reinforcement by pins, may be required. It is the customer’s/user’s responsibility to make sure the dimensioning of the shaft and keyed or other connection, e.g. shrinking or clamping connection, is correct.

The coupling size to be used in conjunction with internal combustion engines is dimensioned and selected with a view to torsional vibration. For a preliminary selection use the engine torque TAN, a general safety factor of S = 1.3 - 1.5 should be applied for ARCUSAFLEX couplings with flexible rubber disc elements of natural/synthetic caout-chouc.
The following requirements should be satisfied for a proper selection of the coupling size:
1. The nominal torque capacity TKN of the coupling shall be at least equal to the max. drive torque TAN while taking the service factors into account
Calculate the driving torque TAN Given a driving powe PAN and a coupling speed nAN, the driving torque is calculated as follows:
The temperature factor St allows for a decreasing load carrying capability of the coupling at elevated ambient temperatures. In this connection St = St1 is valid for St = St2
2. The maximum torque capacity TKmax of the coupling shall be at least equal to the highest torque Tmax encountered in ope-ration while taking the temperature factor S t into account
3. The permissible continuous fatigue torque under reversing stresses TKW of the coupling should be at least equal to the highest fatigue torque under reversing stresses TW encoun-
tered throughout the operating speed range while taking the temperature and frequency into account.
The frequency factor Sf allows for the frequency dependence of the permissible continuous vibratory torque under reversing stresses TKW (10 Hz) when operating with a different frequency fx
TkW (10 Hz) ≥ TW ∙ St ∙ Sf
TKmax ≥ TKmax ∙ St
TKN ≥ TAN ∙ St
Sf = √ fx___10

St2 1.5 1.5 1.5 1.7 1.9 2.1 2.3 2.5
The dimensioning of the coupling should be checked for permissible coupling loads by means of a torsional vibration analysis which will be conducted by us on request. When using ARCUSAFLEX couplings in drives with great torque transmission variations, an additional safety factor should be applied for torque transmission to the driven machine. Lists specifying couplings assigned to different ratings and torsional vibration conditions are available for all common internal combustion engines operating at constant speeds to facilitate your selection of an operationally safe coupling.
The coupling can be equipped with an additional balancing mass on the primary or secondary side, if this is required due to the torsional vibration conditions or for control reasons.
Further information for the torsional vibration calculation and for use of the ARCUSAFLEX rubber disc coupling are available on request.

Mounting instructionsType AC-T...F2 with taper bushing
Tightening torques for mounting the taper bush
Table 1
How to mount the taper bush
1. The outer taper of the taper bush and the bore with the inner taper of the element hub shall show bright metal and must be free of grease prior to mounting. Preservatives must be removed completely.
2. Insert the taper bush into the element hub and line up all connecting bores. Make sure that half threaded holes coincide with half plain holes (Fig. 1).
3. Screw in lightly greased or oiled assembly screws. Do not tighten the screws yet (Fig. 2).
4. Slide the element hub with inserted taper bush onto the cleaned shaft with keyway and put it into the mounting position LX (Fig. 3).
5. Tighten the screws uniformly up to the tightening torque MA1
specified in table 1 using a torque wrench.
6. The screws can be retightened again by tapping against the taper bush with a hammer using an intermediate plate. Repeat, if necessary.
How to remove the element hub with taper bush
1. Loosen and remove all screws. Depending on the taper bush size, screw either 1 or 2 greased screws into the half pulling-off thread(s) of the taper bush (Fig. 4).
2. Tighten the screws uniformly until the taper bush is loose in the element hub.
3. As soon as the taper bush is loose, the element hub can be pulled off the shaft together with the taper bush.

Tightening torques
Shaft couplings
All boIts and screws must be tightened to the specified torques during assembly in order to ensure a reliable torque transmission. Prior to putting the machinery into operation, all bolts and screws of the coupling must be checked for proper fit and tightness. The indicated torques apply to an total friction factor of μ = 0.14. For further questions please ask REICHKUPPLUNGEN.
For the tightening torques MA1 see the mounting instruction for taper bushes table 1. For the tightening torques MA3 see table 3.

Table 3 Tightening torques for the bolted hub connection Types AC...F2 and AC...F2.K (grade 8.8)
Note: The aluminium flanges of the coupling sizes AC 2,3 - AC 10D have to be mounted only with washers. We recommend to use washers as big as possible, but minimum dimensions according to DIN 433. If needed bolts of grade 10.9 with suitable washers and the corresponding tightening torque can be used, please consult us.

Alignment
Permissible shaft displacement
Careful alignment of the coupling is an essential requirement for detached, non-flanged machinery in order to ensure proper functioning of the coupling and to avoid premature wear of the rubber element.
Flywheel couplings shall be aligned from the shaft-side coupling half to either one of the machined surfaces of the engine flywheel or engine housing. Where shaft couplings are used, the angular and radial displacements between the two coupling halves are determined by applying the usual dial indicator method. The alignment requirements of the other application components have to be considered additionally.
The permissibility of major shaft displacements depends on a number of factors such as coupling size, shore hardness of the rubber element, operating speed and torque load of the coupling. The following reference values refer to an operating speed of ≈ 1500 rpm.
Precise alignment prevents premature wear of the rubber element.

Larger displacements of short duration, as may occur when starting and stopping the diesel engine, are permissible. These maximum displacements must not occur simultaneous.*) At types AC...F2K and AC...TK the axial fitting length LF of the coupling should always offer a plus tolerance within the possible tolerance range in order to reach max. axial movability of the dismantled coupling element.
Safety precautionslt is the customer‘s and user‘s responsibility to observe the national and international safety rules and laws. Proper safety devices must be provided for the coupling to prevent accidental contact.
Check all bolted connections for the correct tightening torque and fit after a short running period preferably after a test run.

Requested DataCoupling Selection / Torsional Vibration Calculationacc. to the 2-mass-system (DIN 740 part 2)
The dimensioning of the coupling should be supported by a torsional vibration analysis particularly with a view to the acting fatigue torque under reversing stresses. We are able to conduct this analysis according to the 2 or n-mass system when all required technical details are given.
If the driven machine shall be flanged to the engine using an intermediate housing we kindly ask you to advise us the dimensions and details indicated on the following diagram enabling us to optimize the mounting positon of the coupling.
The coupling should always be properly ventilated in the intermediate housing (e.g. through ventilation holes in the housing).
