3 General technical description The ARCUSAFLEX coupling is a highly flexible flywheel coupling with an axial plugin 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 discshaped 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 C a natural/synthetic caoutchouc mixture as a standard version, up to C a more heat resistant mixture and for higher application temperatures up to 3 C a silicone mixture. The inside diameter of the rubber disc element is vulcanized directly to a taper hub or bolton sleeve. The toothed profile on the circumference of the element provides in service a virtually backlashfree, positive plugin connection to the coupling flange. The ARCUSAFLEX flywheel coupling series covers a torque range from Nm (corresponding to approx. kw at 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 and DIN standards. Other flange dimensions or overall lengths can be provided on request. Shafttoshaft 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 M, + 3). The most important attributes and advantages of ARCUSAFLEX couplings Very high torsional flexibility with a linear torsional deflection characteristic High torsional vibration and shock load absorbing capability Backlashfree torque transmission Ease of assembly thanks to the plugin type design with ample axial float Compensation of major misalignments Torque limitation protecting the drive against overload ATEX 95 ACengl_95 3 Kupplungen.de
4 Types ARCUSAFLEX type ACT with taper bush The ARCUSAFLEX flywheel coupling type ACT...F 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 shrinkfitlike connection, free from backlash is established between the coupling hub with rubber disc element and the shaft. Thanks to the use of coercially 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 ACT. The torque, which can be transmitted, depends on the particular taper bush. Advantage: Ease of assembly and disassembly with no need for special tools! Taper bush Flange Taper hub with rubber element ARCUSAFLEX type AC...F with bolted hub The ARCUSAFLEX flywheel coupling type AC...F has the rubber disc element vulcanized to a bolton 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.

For a preliminary selection use the engine torque TAN, a general safety factor of S =.3.5 should be applied for ARCUSAFLEX couplings with flexible rubber disc elements of natural/synthetic caoutchouc. The following requirements should be satisfied for a proper selection of the coupling size:. The nominal torque capacity T KN of the coupling shall be at least equal to the max. drive torque T AN while taking the T KN T AN S t service factors into account Calculate the driving torque T AN Given a driving power P AN and a coupling speed n AN, the driving torque is calculated as follows: The temperature factor S t allows for a decreasing load carrying capability of the coupling at elevated ambient temperatures. In this connection S t =S t is valid for standard version and S t =S t for silicone version. The maximum torque capacity T Kmax of the coupling shall be at least equal to the highest torque T max encountered in operation while taking the temperature factor S t into account 3. The permissible continuous fatigue torque under reversing stresses T KW of the coupling should be at least equal to the highest fatigue torque under reversing stresses T W encountered throughout the operating speed range while taking the temperature and frequency into account. T AN [Nm] = 955 P AN [kw] n AN [min ] C S t.5.4. on request S t T Kmax T Kmax S t T kw ( Hz) T W S t S f The frequency factor S f allows for the frequency dependence of the permissible continuous vibratory torque under reversing stresses T KW ( Hz) when operating with a different frequency f x S f = f x The dimensioning of the coupling should be checked, with a view to the acting fatigue torque, 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. We are able to conduct this analysis according to the or nmass system when all required technical details are given. 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. ACengl_95 9 Kupplungen.de

18 Alignment Careful alignment of the coupling is an essential requirement for detached, nonflanged 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 shaftside 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. ARCUSAFLEX flywheel coupling Type AC...F ARCUSAFLEX flywheel coupling Type ACT...F ARCUSAFLEX shaft coupling Permissible shaft displacement 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 5 rpm. Precise alignment prevents premature wear of the rubber element. Coupling size Angular displacement Radial displacement Axial displacement,5,3, , ,5 7 7,5 D 9 9D,7/,7D D /,9 D Permissible radial displacement Kr [] Permissible angular displacement α [ ] Permissible axial displacement Ka []*) ±.5 ±3 ±4 ±7 + / ±7 ±5 ±7 ±4 ± ±7 ±5 ±4 ±3 ±4 ±3 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...FK 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. D Safety precautions lt 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. Kupplungen.de ACengl_95
