General technical description The 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 0 C a natural/synthetic caoutchouc mixture as a standard version, up to 00 C a more heat resistant mixture and for higher application temperatures up to 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 coupling flange. The flywheel coupling series covers a torque range from 00 0000 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 couplings comply predominantly with the SAE J 0 and DIN standards. Other flange dimensions or overall lengths can be provided on request. Shafttoshaft connections when required can be met by shaft couplings which consist of 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. 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 couplings AC_Pros_e_03 3

Types type ACT with taper bush The 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 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 type AC...F with bolted hub The 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 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 service factors into account T KN T AN S t Calculate the driving torque T AN Given a driving powe P AN and a coupling speed n AN, 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 S t = S t is valid for S t = S t. 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. The frequency factor S f allows for the frequency dependence of the permissible continuous vibratory torque under reversing stresses T KW (0 Hz) when operating with a different frequency f x T AN [Nm] = 9550 C 0 70 0 90 00 0 0 30 S t.5.4. on request S t.5.5.5.7.9..3.5 T Kmax T Kmax S t T kw (0 Hz) T W S t S f S f = f x 0 P AN [kw] n AN [min ] 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 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 coon 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 rubber disc coupling are available on request. AC_Pros_e_03 9

Tightening torques 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 = 0.4.

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. flywheel coupling Type AC...F flywheel coupling Type ACT...F 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 500 rpm. Precise alignment prevents premature wear of the rubber element.

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. AC_Pros_e_033
