1 GEAR OUPLINGS D

2 MAINA GEAR OUPLINGS - INTRODUTION The full-flex gear couplings are employe to mechanically connect two rotating shafts which have to transmit a torque in a torsionally rigi way. The torque is transmitte from hub to sleeve an vice-versa by the working gear teeth, an between the connecting flanges of the two hubs by the set bolts. The gear couplings are flexible to compensate the misalignment of the shafts to be connecte. They compensate both the initial misalignment (support clearances, imensional an geometrical tolerances of the equipment, alignment imperfections), an further alignment moifications (settling an support wear) an/or temperature (expansion). The gear couplings are flexible because their working gear teeth must be able to float an slie, in orer to compensate misalignments. loating is performe by engaging outer spherical gear teeth with inner cylinrical ones, both having proper tangential clearance. The outer spherical gear teeth, olive shape tangential section an "Semitopping" on the hea, enable the gear hubs to float on their central axis, thus allowing their axial slie an the continuous lube flow, while avoiing any harmful stress concentration on the gear teeth. The gear teeth center on their external iameters, with a proper raial clearance, so that the rotating masses o not generate any vibration when operating at low spee an transmitting torque. When the spee an/or the torque get higher, the gear teeth center on their working flas, so istributing the loa on all the teeth. We recommen to perform a ynamic balancing of the rotating masses - grae an requirements to be specifie (see AGMA 000 0) - in case of high rotation spee or when equipment having supports sensitive to mass inbalance are involve. A single engagement of gear teeth (half-coupling) can compensate both angular an axial misalignments; two engagements of gear teeth (complete coupling) are require to compensate also the parallel misalignments. Please remember that angular, parallel, axial an combine misalignments, maximum spee rotation an transmitte torques must be in accorance with the requirements of every kin of coupling, to avoi excessive or early wear. Maintenance an lubrication have to be careful an precise. Please strictly follow our INSTALLATION, USE & MAINTENANE INSTRUTIONS (see pages,,,, ). MAINA gear couplings are obtaine from forge steel ingots, machine an heat treate. Gear couplings can be mae of ifferent types of steel, as AISI, AISI, Nitralloy N//M which are harene an tempere before being machine. To increase the loa capacity, in some types of couplings, the gear teeth can be surface-harene after machining by thermal or thermochemical treatements an, when require, they can be groun. Main treatments are inuction tempering, nitroxiation an gas nitriing. It is also possible to perform antioxiant an anticorrosive treatments in the en stage. We can perform a nitroxiation (N.O.) treatment on our stanar GO-A gear couplings mae of AISI, when require. Besies limiting surface corrosion, this treatment improves surface harness an wear resistance, an increases working gear teeth lifetime even in presence of high misalignments an rotation spees. Unless otherwise require, our gear couplings are properly package, accoring to their imensions, weight, require type of transport an storage. To prevent oxiation, the interface surfaces or the surfaces which have to be submitte to assembly operations are usually protecte by a wax film of TETYL 0 E. The raw (semifinishe) an wie surfaces of spacer tubes are painte, after sanblasting, by one primer acrylic coat an two final epoxy coats; this kin of painting can resist at temperatures up to 00. Different types of coatings can be applie on eman. The torque a gear coupling can transmit as well as its maximum operating spee change accoring to the total misalignment between the shafts to be connecte (see iagrams of spee factor Kv an of loa factor Ki, shown on pages 0, 0, 0 an 0). The gear couplings must be selecte accoring to the operational ata (loa an spee), the application, the nominal an max loa capacities, the nominal spee, the static an ynamic misalignments an the max amitte bore. This catalogue shows the main types an esigns of flex gear couplings employe in the machinery manufacturing; it oes not contain all the possible ifferent esigns. or special solutions, not inclue in this catalogue, please contact MAINA.

More specific an etaile instructions are provie with the goos. To perform all the require operations, use the necessary time an carefully check the work one. Please remember that all the mechanical machinings, like bore an keyway finishing, an the operations of lifting, hanling, assembly, hub shrifitting, installation, alignment, lubrication an maintenance, must be performe by qualifie, well traine an expert personnel only. INSTALLATION - Keep the gear couplings in a proper non-corrosive environment, protecte from ust, humiity an ba weather. Every months, repeat the anticorrosive protection treatment on the machine surfaces. - Before use, remove the gear coupling from the package an check its conition. - Before installation, isassemble the gear coupling in its main components, remove the anticorrosive coat from the machine surfaces an clean the bore surfaces carefully. If toxic chemicals are use for the cleaning operations, follow prescribe safety measures. NEVER USE ORROSIVE PRODUTS. - If the finish bore operations are to be performe, verify that they conform to the imensional an geometrical tolerances, efine in the specifications an in the rawings (see also AGMA 00A). - When working next to a rotating evice, always follow safety proceures: verify that the unit is off an that it cannot restart until the work is finishe. arefully check the safety conitions. The personnel must wear proper clothing, which cannot get caught on the mechanical components. - In orer to facilitate the hanling an lifting of the gear couplings an their components, screw the eyebolts in their bores, employing the require tools an operating in the max safety conitions. Before hanling an lifting, verify the weights of the units an the position of their barycenter, checking with the catalogue an/or the rawings. During the hanling operations, avoi any impact which may amage the machine components. Use proceures an hanling an lifting evices which o not amage the gear couplings an their components. - The gear couplings, when operating uner loa, offer a resistance to the axial slie (translation). An axial force proportional to the transmitte torque contrasts this movement, an its entity is irectly relate to the primitive iameter of the gear teeth an to the value of the ynamic friction coefficient. The reaction force is obtaine as follows: Where: - a = Axial force [kn] a=tnxµ/dp - Tn = Drive Nominal Torque - Dp = Primitive Diameter of the gear teeth [m] - µ = riction oefficient(from 0.0 to 0.), epening on the lubrication conition. In particular emergency conitions the value µ = 0.0 can be taken.

60 INSTALLATION, USE & MAINTENANE - A slight interference of approx. the 0./00 of the iameter is recommene for the hub key shrifitting operations. The following tolerances are suggeste: for the hole an m-r for the shaft. urthermore, after shrifitting, the keys must remain fixe in position on their flas, using the tolerance P for the keyways. or stanar keys in stanar hubs, with the nominal loa conition an heavy, uniirectional uty, it is preferable not to excee a specific pressure on the flas of 0 [N/mm ]. - or keyless shrifittings, interferences from the /00 to the./00 of the iameter are employe, using a tolerance of for the hole an s-x for the shaft, or special fits. In this case always contact MAINA engineering staff who, in accorance with the type of shrifitting an the technical agreements, will evaluate the torque transmittable at the slipping as well as the stress generate in the hub, accoring to AGMA 00-A. In case of shrifittings with high interference on the flex hubs with working gear teeth, the external iameter of the gear teeth must always be reuce by a suitable imension. The threae holes, for fitting the oil pressure removal evices, an the shape of filling holes an grooves are usually execute in accorance with SK prescriptions. Shrifittings can be cylinrical, cylinrical with ouble iameter, conical, conical with interpose bush. onical shrifittings are suitable for hyraulic assembly. - Uniformly heat the hubs, placing them either in an air furnace or in an oil bath, both with thermostatic control. It is also possible to heat the hubs by open flame, taking care not to generate overheatings an frequently checking the temperature with suitable an precise evices. Employing the flame, heat the outer sie of the hubs, carefully avoiing to irect it on the gear teeth; work in max safety conition, far from flammable materials or substances. - The heating temperatures must be evaluate consiering an expansion which generates a clearance between hole an shaft of the./00 of the iameter. The heating temperatures, epening on the shrifitting interference, are -0 for key shrifittings an 0- for keyless shrifittings. Never excee. - After the hub heating, wearing suitable thermal insulate clothing, clear the hole seat of the carbon resiual, using a proper cleaning paper instea of common rags. After cleaning, measure the entity of the expansions. Afterwars, lubricate holes an hub surfaces with pure mineral oil without aitives. In case _ 0., follow our of shrifittings with a friction coefficient µ > specifications (PB 0). - Before shrifitting the hub, check that the flange sleeves or the removable sie flanges are correctly positione on the shafts. Verify the seal integrity of these components an check that the seals are correctly inserte in their seats. - During the shrifitting operations, avoi any contact between the hot hub surfaces an the rubber seals. Position the gear sleeves or the sie flanges on the hubs only when the hub temperature goes below 0. - Position the machines to be connecte so that the axial istance between the hubs (or between the heas of the shafts) complies an is in tolerance with the imension A shown in the catalogue or on the rawings. Obviously, this imension has to be in accorance with any possible expansion or axial movements/strokes of the connecte shafts or to the axial clearance limiting evices. Moreover, to allow the half coupling aitional alignment operations, the gear hubs must have the capability to move back so as to show a part of the hub; the minimum necessary movement is referre to as "ca" in TAB I. To make both the assembly an alignment operations an the aitional gear teeth checks easier, it shoul be possible to move the gear sleeves back as far as they withraw from the gear teeth. If there is not enough space, we recommen requesting gear couplings equippe with removable sie flanges. To remove the gear couplings without moving the connecte units, request couplings equippe with intermeiate spacer. Perform the angular an parallel alignment of the half couplings an of the connecte machines. To assure long coupling gear teeth lifetime it is better to assure that, after the machines alignment operation an in ynamic working conitions, the initial resiual misalignment between the two half couplings is very close to the /00 of the coupling gear teeth istance L. The max amissible limit is efine for every kin of gear couplings as the max ynamic angle value. This must always be lower than the allowe angle epening on the max working spee (see Kv iagrams). Secure the machines to their founations an frames, tightening all the locking bolts an nuts. After this operation, check the half coupling alignment again. Assemble the gear sleeves an the sie flanges on the hubs, carefully avoiing any seal amage, then fill the half coupling with grease by a spatula. lose the gear couplings, assembling all their components an evices. To assure a perfect fitting, apply a light coat of mastic on the flanges before closing them. During the assembly operations, respect the mutual position of the components; follow the assembly marks showing the right alignment an orientation of the hubs. Screw the main flange connection bolts, carefully tightening them at the torques shown in TAB IV. arefully screw an tighten all the remaining bolts. or high-spee gear couplings ynamically balance, in orer to maintain the balancing conition with a reuce resiual inbalance, besies observing the assembly marks use uring the balancing operations, it is also recommene to respect the position of the bolts which, in this case, must not be replace or mixe. omplete the lubrication through the grease nipples or the conical plugs. Do not excee bar of pressure. Verify that the floating part of the gear coupling (gear hubs an spacers) is able to move axially of the imension (see TAB ). heck the tightening of all bolts an screws, grease nipples an/or plugs. Before starting the machines, place proper safety protections aroun the gear coupling. After the start-up, the founation settling an a suitable perio of working at the max torques, spee an ifferent temperatures (for a perio of about months), check the wear, verify an revise, if necessary, the alignment conition.

61 INSTALLATION, USE & MAINTENANE ORRET ALIGNMENT IS ESSENTIAL TO ENSURE A LONG OPERATING LIETIME - Determine the angular misalignment value processing, in accorance with the tables, the measurements of the hea parallelism between the reference frontal surfaces of the two hubs. or this purpose, by inserting the thickness gauge between the heas of the two hubs, perform a first 0 test to ientify the position an the min an max entity of the istance between the hubs. After efining the extreme positions, perform a precise measurement of points at 0, like A in IG.0. The max ifference between two values at 0 is A Determine the parallel misalignment value processing, accoring to the tables, the mutual eccentricity between the reference iameter of the two hubs. or this purpose, rigily fasten the test inicator on a ban in two halfs to the reference iameter of a hub, like B in IG.0. Verify that the whole unit, uring a 0 rotation, oes not have any clearance, afterwars measure the min an max eccentricity. The max ifference is P - or gear couplings with tubular spacer or with floating shaft, check the hea parallelism between the hubs reference surfaces, using an insie micrometer positione like in IG.0 or a comparator positione like D in IG.0 or E in IG.0. The max ifference between two values at 0 is A The hub eccentricity is measure by a comparator, positione like in IG.0, G in IG.0 or in IG.0. The max ifference is P Gear couplings with spacer, having a long istance between the gear teeth, require an aligment accuracy lower than the normal gear couplings o. The initial static no-loa alignment conition (machines off) must consier what will happen uner loa (ynamic conition). This means that it shoul be also able to compensate the misalignments generate by loa an temperatures (see point of INSTALLATION INSTRUTIONS). heck the alignment conition of the half couplings, using for this purpose a moern laser equipment. In this case, to perform the alignment operations, the instructions for the use of the equipment have to be followe.
