8 1.2 PRODUCT SELECTION For correctly selectng a gear reducer or geared motor, several essental peces of data are requred: 1. The rotatonal nput speed to the gear reducer (n 1 ) and the rotatonal output speed (n 2 ). Through these two values t s possble to calculate the reducton rato () of the gear reducer usng the followng formula: =n 1 /n 2 2. The torque requred by the applcaton (Mr 2 ). The geared motor or gear reducer can be selected once ths data s known. Ths gude helps you to select the rght product n just a few steps: Geared motor selecton 1. Determne the applcaton s actual servce factor (s.f.). Ths parameter depends on the type of load of the powered machne, the number of starts per hour and the hours of operaton (refer to the Servce factor paragraph). 2. Calculate the nput power Pr 1 usng the requred torque value Mr 2, the speed n 2 and dynamc effcency value. Pr1= (Mr 2 *n 2 )/(9550*η d ). The dynamc effcency value depends on the type of gear reducer and on the number of gear reducton stages. (To calculate the effcency value see ts page). 3. Consult the geared motor performance tables and dentfy a normalsed power value exceedng the requred power Pr 1, such that: Pr 1 4. Once the sutable nomnal power has been dentfed, select the geared motor capable of generatng the rotatonal speed closest to the desred n 2 value and wth servce factor s.f. greater or equal to that requred by the applcaton. In the geared motor selecton tables the combnatons nclude 2-pole, 4-pole and 6-pole motors powered at 50Hz. Gear reducer selecton 1. Determne the applcaton s servce factor (s.f.) (consult to the Servce factor paragraph on ts page). 2. Calculate the reducton rato from the requested output speed n 2 and from the nput speed n1. =n 1 /n 2 3. Calculate the torque Mc 2 for selectng the gear reducer through the torque requred by the applcaton Mr 2 and the servce factor s.f.: Mc 2 =Mr 2 *(f.s.) 4. Consult the Gear Reducer Performance tables lookng for the reducer that, wth the reducton rato closer to the calculated one, has a nomnal torque so that: Mc 2 Checks Once the gear reducer or geared motor has been selected, the followng checks should be performed: A. Maxmum torque Generally, the maxmum torque (peak nstantaneous load) that can be appled to the gear reducer must not exceed 200% of the nomnal torque (ATEX - M 2 max). B. Radal loads 1. Verfy that the radal loads actng on the nput and/or output shafts are wthn wth the values ndcated n the catalogue. If they exceed these values, ncrease the sze of the gear reducer or modfy the external load capacty. Durng the checkng phase, t s mportant to remember that the values ndcated n the catalogue refer to loads actng on the mdpont of the shaft protruson, therefore, f the load s appled to a dfferent poston, approprate formulas must be used to calculate the admssble load n the desred poston (refer to the Radal loads paragraph). 2. If accessory output shafts are present, make sure that the appled load s compatble wth shaft sze. If help s needed: contact MOTOVARIO TECHNICAL SERVICE. C. If an electrc motor s gong to be ftted to the selected gear reducer, check for ts applcablty by referrng to the confguraton table (see paragraph flange avalablty ). From IEC 180 motors, verfy f necessary to support the motor wth feet. In case of need please contact MOTOVARIO TECHNICAL SERVICE. 7

9 1.3 SERVICE FACTOR The servce factor (f.s.) depends on the operatng condtons the gear reducer s subjected to. The parameters that need to be taken nto consderaton to select the most adequate servce factor correctly comprse: LOAD: type of load of the operated machne : A - B - C length of daly operatng tme: hours/day ( ) start-up frequency: starts/hour (*) A - unform = fa 0,3 B - moderate shocks = fa 3 C - heavy shocks = fa 10 fa = Je/Jm Je [kgm 2 ] moment of reduced external nerta at the drve-shaft Jm [kgm 2 ] moment of nerta of motor If fa > 10 call our Techncal Servce. A. Screw feeders for lght materals, fans, assembly lnes, conveyor belts for lght materals, small mxers, lfts, cleanng machnes, fllers, control machnes. B. Wndng devces, woodworkng machne feeders, goods lfts, balancers, threadng machnes, medum mxers, conveyor belts for heavy materals, wnches, sldng doors, fertlzer scrapers, packng machnes, concrete mxers, crane mechansms, mllng cutters, foldng machnes, gear pumps. C. Mxers for heavy materals, shears, presses, centrfuges, rotatng supports, wnches and lfts for heavy materals, grndng lathes, stone mlls, bucket elevators, drllng machnes, hammer mlls, cam presses, foldng machnes, turntables, tumblng barrels, vbrators, shredders. 8

10 1.4 INSTALLATION To nstall the gear reducer t s necessary to note the followng recommendatons: Check the correct drecton of rotaton of the gear reducer output shaft before fttng the unt to the machne. In the case of partcularly lengthy perods of storage (4/6 months), f the ol seal s not mmersed n the lubrcant nsde the unt, t s recommended to change t snce the rubber could stck to the shaft or may even have lost the elastcty t needs to functon properly. Whenever possble, protect the gear reducer aganst solar radaton and bad weather. Ensure the motor cools correctly by ensurng good passage of ar from the fan sde. In the case of ambent temperatures < -5 C or > +40 C call the Techncal Servce. The varous parts (pulleys, gear wheels, couplngs, shafts, etc.) must be mounted on the sold or hollow shafts usng specal threaded holes or other systems that anyhow ensure correct operaton wthout rskng damage to the bearngs or external parts of the unts. Lubrcate the surfaces n contact to avod sezure or oxdaton. Pantng must defntely not go over rubber parts and the holes on the breather plugs, f any. For unts equpped wth ol plugs, replace the closed plug used for shppng wth the specal breather plug. Check the correct level of the lubrcant through the ndcator, f there s one. Startng must take place gradually, wthout mmedately applyng the maxmum load. When there are parts, objects or materals under the motor drve that can be damaged by even lmted spllage of ol, specal protecton should be ftted. Please note: n the event of a cover wth adhesve label havng to be replaced, you wll have to stck a new label onto the new cover. Please contact Motovaro and we can supply you wth one. 9

It s related to the load appled on the centre lne of the shaft and n the most unfavourable condtons of angle of applcaton and drecton of rotaton. The maxmum admssble axal loads are 1/5 of the value of the gven radal load when they are appled n combnaton wth the radal load. The tables relatng to the output shafts gve the maxmum admssble value. Ths value must never be exceeded snce t relates to the strength of the case. Partcular condtons of radal load hgher than the lmts of the catalogue may occur. In ths case, call our Techncal Sevce and provde detals on the applcaton: drecton of the load, drecton of rotaton of the shaft, type of servce. In case of double extenson shafts wth radal load appled on both ends, the max. admssble radal loads must be defned accordng to the specfc runnng condtons, n ths case call our Techncal Servce. The radal load on the shaft s calculated wth the followng formula: Fre=(2000*M*fz)/D or Fre Resultng radal load M Torque on the shaft D [mm] Dameter of the transmsson member mounted on the shaft - Value of the maxmum admtted radal load (see relatve tables) fz = 1,1 gear pnon - 1,4 chan wheel - 1,7 v-pulley - 2,5 flat pulley Input When the radal load s not on the center lne of the shaft, t s necessary to adjust the admssble radal load wth the followng formula: Frx=(*a)/(b+x) a, b = values gven n the tables x = dstance from the pont of applcaton of the load to the shaft shoulder NRV/NRV-P a b max(**) ISW a b max(**) IHW a b max(**) (** max) Max admssble value of the reducer n statc condtons and/or for lmted operatons.

46 2.12 LUBRICATION Informaton In cases of ambent temperatures not envsaged n the table, call our Techncal Servce. In the case of temperatures under -30 C or over 60 C t s necessary to use ol seals wth specal propertes. For operatng ranges wth temperatures under 0 C t s necessary to consder the followng: 1. The motors need to be sutable for operaton at the envsaged ambent temperature. 2. The power of the electrc motor needs to be adequate for exceedng the hgher startng torques requred. 3. In case of cast-ron gear reducers, pay attenton to mpact loads snce cast ron may have problems of fraglty at temperatures under -15 C. 4. Durng the early stages of servce, problems of lubrcaton may arse due to the hgh level of vscosty taken on by the ol and so t s wse to have a few mnutes of rotaton under no load. Ol (NON Atex products) must be changed after approx hours/2 years of operaton; ths tme vares based on the type of servce and on the envronment nsde whch the gear reducer s nstalled.

78 4.5 TORQUE LIMITER Operatng prncple In ths mechancal devce the transmsson of movement takes place by means of frcton between the drvng surface (nput shaft (10)) and the drven surface (wormwheel (9)). These are subject of a determned compresson created by the plate (7) whch s generated by two bellevlle washers (6), arranged n seres. The bellevlle washers acton s generated by the bushng (3), drven by the external lockng rng nut (1) whch s screwed on the output shaft. The shft (X) s guaranteed by the connecton between the two concal elements of the hub (2) and the worm wheel. The transmsson of movement has a standard operaton up to a maxmum admssble torque value (slp torque); over ths value the torque lmter starts to work generatng a slp between the worm wheel, whch contnues to spn conducted by the nput shaft, and the hub whch remans stll. Over the slp torque expected from the regulaton, the torque lmter s stll on hold : t transmts the set value and t doesn t transmt hgher values. Ths ensures to the machne to restart automatcally wthout external acton. For safety reasons t sn t recommended to nstall ths devce n lftng equpment: n case of overloads or rregulartes, durng the shft, the weght could not be mantaned n suspenson. 77

79 4.5 TORQUE LIMITER Descrpton The torque lmter s a mechancal devce desgned to protect the transmsson from movement caused by accdental overloads or rregulartes. It s appled to the output of the worm gear reducers and t works as an nternal frcton appled on the output shaft, whch can be adjusted manually through an external lockng rng nut. Compared to electronc or external mechancal devces, ths soluton presents the followng advantages: Lmted addtonal dmensons compared to the verson wthout the torque lmter; Hollow output shaft wthout changes n terms of dameter compared to the standard verson; Quck acton drectly on the transmsson that must be protected; It has been desgned for ol-bath operaton, therefore wear-free and relable; Manual adjustment of the slp torque; Over the slp torque, the torque lmter s stll on hold, ensurng the automatc machne restart wthout external nterventon; Usng the torque lmter, t s possble also to rotate the gearbox shaft by loosenng the external lockng rng nut, for example n case of mechancal locks due to worm rreversblty. The torque lmter devce must to be nstalled as a protecton system for accdental events and not as protecton of wrong gearbox selecton (for example after selectng a gearbox wth a low servce factor compared wth the real needs of the applcaton). The torque lmter s avalable for worm gear reducers type NMRL050 / NMRL-P / SWL and t s applcable n all combned unt confguratons provded n the catalogue, usually on the last gearbox. The torque lmter s suppled on the gearbox output shaft n J or K poston Slp torque settng A slp torque settng s easly adjustable from the outsde through the rotaton of the lockng rng nut, characterzed by 4 marks to defne the number of turns (each mark s equvalent to ¼ of a turn). The devce s prelmnary set durng the assembly phase. The followng factors may affect the settng: temperature and perod of adjustment. It s therefore recommended, durng the nstallaton, to actually verfy the slp torque lmt, n accordng to the real needs of the applcaton. The standard drecton of rotaton for the regstraton of the rng nut s clockwse. Lookng frontally from the rng nut sde, the torque lmter s n J poston when the motor poston s on the rght sde; wth the motor on left sde the torque lmter s n K poston. It s recommended for long stops, even f the machne restarts automatcally, to return the rng nut to ts orgnal poston and to set t agan. As prevously mentoned, for each reducers sze ( ) the slp torque range depends by the rato and the drecton of rotaton of the gearbox, whch affects the tolerances between the two concal components that generate the slp (there s an axal component whch tends to approach or move ther away). Therefore n the settng dagrams are shown two lnes whch represent the approxmate lmts wthn the provded slp torque could change. The slp torque settng must be always checked afterward to determne f the number of turns of the rng nut guarantees the desred slp torque value.
