DISC COUPINGS
DISC COUPINGS MAIN FEATURES The isc coupling is of the continuous ring laminate metallic iaphragm type with blaes in stainless steel. The torque is transmitte in pure tension through alternate riving an riven bolts on a coon pitch circle iameter. The isc couplings assure the following basic avantage: - no lubrification - no maintenance - high rotation spees - low weight with high torque capacity - strong construction - permit axial, parallel an angular misalignment - work in both rotation irections - no torsional clearance with high torsional rigiity - high an low temperature operation - operation in averse environmental conitions - possibility to replace the element blaes without isplacement of couple machines Disc couplings in the stanar version are manufacture with stainless steel blaes, bolts an bushes in high resistant steel an the other parts in carbon steel. The couplings are operational in a temperature range from - C to +0 C equippe with self-locking metallic nuts an from - C up to +100 C if equippe with nut with nylon insert. Disc couplings are manufacture upon specific request: - in all stainless components to face specific corrosion problems - in special steel for very low operational temperatures - with hubs an spacers in titanium or aluminium alloys to reuce the weight an the inertia - with spacer in composite to reuce the weight an to get very high lenght without intermeiate bearing - accoring with 94/9/CE (Atex) stanars. TYPOOGY Disc couplings are esigne an manufacture in ifferent types to meet the requirements of the ifferent en uses applications: - The series HBSX-GCSX-HPSX-BE with ouble elements compose by two hubs, two element blaes an one spacer allow angular, axial an parallel misalignment. The catalogue shows the allowe values. The axial an parallel misalignments are the consequence of the angular misalignment an therefore inversally proportional, i.e. the increase of one value correspons to the ecrease of the other one. The values of axial thrust generate by the axial misalignment are available asking for to our technical office. Upon request the lenghts of the hubs an of the spacer may be moifie. - The series GCSX has the same features of the range HBSX with the only ifference that the element blaes are with unrivette bushes. This range has been esigne to improve the torque capacity with same size of the coupling. - The series HBX-GCX-HPX with single element compose by two hubs an one element blaes allow an angular an axial misalignment, but not parallel one. For this reason their use is subject to the perfect alignment between the riving an riven machines. Normally these couplings are use in ouble space with a shaft, in orer to bring the transmission as for two elements. - The series GCSTX-GCSX/CTFX are an alternative version of series GCSX an are isegne specifically fo the use in the cooling towers. For this en use, the spacer ens are protecte by close caps to avoi the access of water an vapours to prevent the internal oxyation. The size tables relate to the couplings for cooling towers give the spacer length for operating spees till 1500 RPM. For higher spee requirements refer to our technical service. - The series GCSTX-FC with spacer in composite esigne for cooling towers, allows a weight reuction of about 70% with easy installation an permits to reach the spacer length up to six meters without bearings. The size tables relate to the couplings for cooling towers give the spacer length for operating spees till 1500 RPM. For higher spee requirements refer to our technical service. A backstop evice is equipable to these series of couplings on the motor sie hub to assure one rotation irection only. - The series HBSX/AH-GCSX/AH with aapter an oversize hubs allow to get hubs with bigger size bores. This particular configuration allows to effect the balancing operation of the assemble aapters, element blaes an spacer without removing them, which assure to obtain a very high grae of balancing repeteability. - The series HBSX/RH with reverse hubs an with the spacer ivie in two halfs is esigne to replace the coonly coercialize gear couplings with isc couplings perfectly interchangeable in operational an size aspects with the avantage above mentione. With this range of coupling it is possible to replace the gear couplings also on alreay operating machines without changing the position of the riving an riven machines.
SEECTION The proper size selection of couplings epens by several factors. First of all the choice have to be one for a coupling suitable to transmit the imum torque necessary to suit the nominal power (installe power) of the riving machine assuming that it will be higher than the riven machine power (absorbe power). After having etermine the power (HP or KW) to be transmitte as well as the relate operating spee (RPM) an the suitable service factor (Fs) it is possible to select the coupling with the use of the formulas here below. It is also necessary to check that the shaft iameters of the riving an riven machines are lower than the allowe bore of the coupling (see Table A). Selection of coupling base on power: HP or KW Power = --------------------- x Fs RPM Selection of coupling base on torque: HP x 70 or KW x 9550 Torque (Nm) = --------------------------------------------------- x Fs RPM The couplings inclue in this catalogue withstan a start up, or occasional overloa torque, equal to 1,5 times the nominal torque an a short circuit torque equal to 3 times the nominal torque. For all applications it is foreseen a service factor as shown on the table C (such table gives service factor approximate values corresponing to the main applications). BAANCING For couplings with finishe bores or wele spacer it is carrie out upon request the inamic balancing, grae G 6.3 ISO 1940 unless otherwise require. It is anyway nacesary to etermine if the balancing has to be realize with or without key way. The balancing is one with a shaft passing through the coupling an blocke in the bores of the hubs or with separate components. To obtain an high balancing, repeteability grae is avisable use the range with aapter (AH pag. 10 22). Consiering that, ue to the assembly tolerance, it is not possible to grant the assemble unit riving machine/coupling/riven machine balancing tolerance within the establishe grae, manufacturer has eveloppe an experience a specific proceure to permit the balancing on site of the isc couplings by fitting up grub screws on specific holes realize uring the coupling manufacture. This solution is specifically use with high spee couplings. Consequently to the high machining accuracy in the manufacture, meium spee couplings o not require balancing unless for exceptionally heavy couplings. Normally the isc couplings with iameter till 100 at 4500 RPM, with iameter from 100 to 0 at 3000 RPM, with iameter from 0 to 500 at 1500 RPM, are manufacture an elivere without balancing. SAFETY ADVICE The couplings are manufacture accoring to the up to ate technical know-how an supplie for safe operation. Moifications non authorise by manufaturer, that can compromise the working safety, are not permitte. The couplings must be employe only within the limit conition of the technical supply specification an respecting the safety running rules.

Disc coupling assembling an alignment instructions Disc couplings tolerate misalignments which vary with the number of isc pack bolts. A 4 bolts couplings, for instance, allows a angular misalignment of 1 corresponing to 0,0 per (ra), value that, multiplie by the istance between the isc packs or by the coupling outer iameter, give the value of the parallel an angular misalignment in. Those imum figures are not intene to be use for initial alignment, because the allowable parallel misalignment uner working conition will vary accoring to the axial eflection an viceversa. Both those values will vary with the spee variation. Therefore it is important that initial alignment is as right as possible, in orer to allow variations of conitions uring operation. COUPING ASSEMBING Hubs have to be assemble on machine shafts so that the hub flange faces are aligne with shaft ens, except in case of ifferent instruction. The length of spacer complete of isc packs, an eventual aapters, will be then equal to the istance between shaft ens (DBSE). The hubs with bores foreseen for low interference fit have to be uniformly heate at 1-130 C an quickly assemble on shafts. Do not heat locally in orer to avoi stresses an permanent istorsions. The couplings with aapters are assemble with centring calibrate steps; for assembling an isassembling the central part it is necessary to press the same in orer to get over the step. For small/meium size coupling isassembling it is sufficient to insert a screwriver between the aapter an the hub flange, taking care not amage the connection surfaces meanwhile for big size couplings, on the flanges are foreseen tappe holes for pressing bolts. When assembling isc pack of the series GC, that have loose sleeves, it is important that the roune surfaces of the same are in the isc pack sie. The higher sleeves have to be assemble into the flange large through holes. When utilising the coupling type GCSX/CTFX on cooling towers or on long spacer rive, we recoen to start the alignment proceure from the en hubs, consiering for alignment the values given by, setting up before the spacer shaft with support an then the other parts. AIGNMENT PROCEDURE The alignment proceure will vary accoring to the involve machinery. Then we are not proposing to give operation etails, but to propose misalignment limits an suggest the ways for checking the same. AXIA AIGNMENT Generally, lower is the number of coupling isc pack bolts, higher is the allowe tolerance uring initial alignment. We avice to respect the following limits, unless ifferent specific instruction are given. The istance between hub flanges (2) must be than: For 4 bolts coupling a = ± 1 For 6 bolts coupling a = ± 0,8 For 8 bolts coupling a = ± 0,5 For 10 bolts coupling a = ± 0,5 For 12 bolts coupling a = ± 0,5 PARAE AND ANGUAR AIGNMENT We have three ways for checking the parallel an angular alignment. The most use is the classic one with the ial gauge, supporte by the more innovative one with laser system. The more practical way consists in checking the gap between flanges, on both isc packs, on 360 ; that is possible if all coupling components are assemble. This metho can be use also to verify the coupling alignment time going, without removing the transmission components. With this last proceure we check simultaneously the parallel p an angular α alignments. Check flange gap at 12 an 16 o clock position (check of parallel an vertical angular alignment) Check flange gap at 9 an 3 o clock position (check of parallel an horizontal angular alignment)
The values S - Smin must be of pα (): For 4 bolts coupling of pα () = [α (ra) x D] where α (ra) = 0.004 For 6 bolts coupling of pα () = [α (ra) x D] where α (ra) = 0.003 For 8 bolts coupling of pα () = [α (ra) x D] where α (ra) = 0.002 For 10 bolts coupling of pα () = [α (ra) x D] where α (ra) = 0.0015 For 12 bolts coupling of pα () = [α (ra) x D] where α (ra) = 0.001 Then: Parallel alignment p () (ra) x a Angular alignment α () (ra) x D The state values are for general use an can vary in specific cases, for instance for couplings working at high ilatations or spees. In any case, better is the initial alignment, higher is the tolerance at unforeseen misalignment ue to structure movements. After having properly aligne the coupling, make sure that all the bolts or fixing screws are tightene. If possible check the tightening after some hours of operation too. BAANCING Usually uring balancing on flanges, of couplings for meium an high spees, are printe some references (e.g. alphabetic letters) to be respecte when assembling. For making easier the precision balancing on site we foresee some tappe hole on flanges in orer to have the possibility to a balancing weights. α () = S - Smin α (ra) = S - Smin D
