3 General design AC The is a highly flexible flywheel 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 7 F (0 C) a natural/synthetic caoutchouc mixture as a standard version, up to 22 F (00 C) a more heat resistant mixture and for higher application temperatures up to 2 F (30 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 flange. The flywheel series covers a torque range from lbin ( Nm) (corresponding to approx. 500 kw at 000 rpm). Element versions of different torsional stiffnesses are available for optimizing the torsional vibration range. The flange connection dimensions of s comply predominantly with the SAE J 20 and DIN 2 standards. Other flange dimensions or overall lengths can be provided on request. Shafttoshaft connections when required can be met by shaft s which consist of flywheel s of the standard design equipped with a second hub. Type approvals by a number of leading classification societies are available. If required, s complete with fail safe devices can also be supplied. s 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). Main features of the highly flexible ARCUSAFLEX s 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 AC_us_04 Reich USA Corporation, Mahwah, NJ (20) FAX (020)

4 Types Taper bushing Flange Taper hub with rubber element type ACT with taper bush The ARCUSAFLEX flywheel type ACT...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 shrinkfitlike connection, free from backlash is established between the 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 hub is omitted for the ARCUSAFLEX 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! Bolted hub Flange Element with bolton sleeve type AC...F2 with bolted hub The ARCUSAFLEX flywheel type AC...F2 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 hub. 4 Reich USA Corporation, Mahwah, NJ (20) FAX (020) AC_us_04

It is the customer s/user s responsibility to ensure there are no inadmissible loads acting on all the components. Especially existing SAE bolt connections have to be checked regarding the transmissible torque, if necessary other measures, e.g. additional reinforcement by pins, may be required. It is also the customer s/user s responsibility to make surethe dimensioning of the shaft and keyed or other connection is correct. With the type ACT...F2 the transmissible torque is dependant among others on the torque capacity of the taper bush. REICHKUPPLGEN have an extensive programme of s to cover nearly every drive configuration. Furthermore customized solutions can be developed and be manufactured also in small series or as prototypes.

For a preliminary selection use the engine torque TAN, a general safety factor of S =.3.5 should be applied for s with flexible rubber disc elements of natural/synthetic caoutchouc. The following requirements should be satisfied for a proper selection of the :. The nominal torque capacity T KN of the should be at least equal to the max. engine torque T AN at any operating temperature while taking the temperature factor S t into account. Calculation of the nominal engine torque: The temperature factor S t allows for a decreasing load carrying capability of the at elevated ambient temperatures. In this connection S t = S t is valid for S t = S t2 2. The maximum torque capacity T Kmax of the should be at least equal to the highest torque T max at any operating temperature while taking the temperature factor S t into account. T KN T AN.

The permissible continuous fatigue torque under reversing stresses T KW of the 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.

St. Sf S f f = X 0 The dimensioning of the should be checked for permissible loads by means of a torsional vibration analysis which will be conducted by us on request. When using s in drives with great torque transmission variations, an additional safety factor should be applied for torque transmission to the driven machine. Lists specifying s 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. The 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 rubber disc are available upon request. AC_us_04 Reich USA Corporation, Mahwah, NJ (20) FAX (020)

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. ). 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 MA specified in table using a torque wrench..

23 Alignment Careful alignment of the is an essential requirement for detached, nonflanged machinery in order to ensure proper functioning of the and to avoid premature wear of the rubber element. Flywheel s shall be aligned from the shaftside half to either one of the machined surfaces of the engine flywheel or engine housing. Where shaft s are used, the angular and radial displacements between the two halves are determined by applying the usual dial indicator method. The alignment requirements of the other application components have to be considered additionally. Permissible shaft displacement The permissibility of major shaft displacements depends on a number of factors such as, shore hardness of the rubber element, operating speed and torque load of the. The following reference values refer to an operating speed of 500 rpm. Precise alignment prevents premature wear of the rubber element.
