Ngaphezu kwezingxenye ze-preset clearance bearing, i-Timken isungule izindlela ezinhlanu ezivame ukusetshenziswa zokusetha ngokuzenzakalelayo i-bearing clearance (okungukuthi i-SET-RIGHT, i-ACRO-SET, i-PROJECTA-SET, i-TORQUE-SET kanye ne-CLAMP-SET) njengezinketho zokulungisa ngesandla. Bheka kuThebula 1- "Ukuqhathaniswa kwezindlela ze-tapered roller bearing set clearance" ukuze ubonise izici ezahlukene zalezi zindlela ngefomethi yethebula. Umugqa wokuqala waleli thebula uqhathanisa ikhono lendlela ngayinye lokulawula ngokufanele "ububanzi" be-bearing clearance yokufaka. Lawa manani asetshenziswa kuphela ukubonisa izici eziphelele zendlela ngayinye ekusetheni i-clearance, kungakhathaliseki ukuthi i-clearance isethwe ku-"preload" noma "axial clearance". Isibonelo, ngaphansi kwekholomu ye-SET-RIGHT, ushintsho lwe-clearance olulindelekile (i-high probability interval noma i-6σ), ngenxa yokulawula ukubekezelelana kwe-bearing kanye ne-housing/shaft, lungase lusuke ku-0.008 inches kuya ku-0.014 inches. Ububanzi be-clearance bungahlukaniswa phakathi kwe-axial clearance kanye ne-preload ukuze kukhuliswe ukusebenza kwe-bearing/application. Bheka uMfanekiso 5- "Ukusetshenziswa Kwendlela Ezenzakalelayo Yokusetha I-Bearing Clearance". Lesi sibalo sisebenzisa umklamo ojwayelekile wetrakhi yezolimo enamasondo amane njengesibonelo ukubonisa ukusetshenziswa okujwayelekile kwendlela yokusetha i-bearing roller setting clearance.
Sizoxoxa ngokuningiliziwe ngezincazelo ezithile, imibono kanye nezinqubo ezisemthethweni zokusetshenziswa kwendlela ngayinye ezahlukweni ezilandelayo zale module. Indlela ye-SET-RIGHT ithola imvume edingekayo ngokulawula ukubekezelelana kwe-bearing kanye nohlelo lokufaka, ngaphandle kwesidingo sokulungisa ngesandla i-TIMKEN tapered roller bearing. Sisebenzisa imithetho yamathuba kanye nezibalo ukubikezela umphumela walezi zimvumelwano ekuvunyelweni kwe-bearing. Ngokuvamile, indlela ye-SET-RIGHT idinga ukulawulwa okuqinile kokubekezelelana komshini we-shaft/bearing housing, ngenkathi ilawula ngokuqinile (ngosizo lwamamaki okunemba namakhodi) ukubekezelelana okubucayi kwama-bearing. Le ndlela ikholelwa ukuthi ingxenye ngayinye ekuhlanganisweni inezimvumelwano ezibucayi futhi idinga ukulawulwa ngaphakathi kobubanzi obuthile. Umthetho wamathuba ukhombisa ukuthi amathuba okuba ingxenye ngayinye ekuhlanganisweni ibe ukubekezelelana okuncane noma inhlanganisela yezimvumelwano ezinkulu mancane kakhulu. Futhi landela "ukusatshalaliswa okujwayelekile kokubekezelelana" (Isithombe 6), ngokusho kwemithetho yezibalo, ukufakwa kwazo zonke izingxenye zosayizi kuvame ukuwela phakathi kobubanzi obungaba khona bokubekezelelana. Umgomo wendlela ye-SET-RIGHT ukulawula kuphela ukubekezelelana okubaluleke kakhulu okuthinta imvume ye-bearing. Lokhu kubekezelelana kungaba ngaphakathi ngokuphelele kwebheri, noma kungabandakanya izingxenye ezithile zokufaka (okungukuthi, ububanzi u-A no-B kuMfanekiso 1 noma uMfanekiso 7, kanye nobubanzi bangaphandle bomgodi kanye nobubanzi bangaphakathi bebheri). Umphumela uba ukuthi, ngamathuba aphezulu, imvume yokufaka ibheri izowela ngaphakathi kwendlela eyamukelekayo ye-SET-RIGHT. Umfanekiso 6.

Akukho ukulungiswa okudingekayo uma usebenzisa indlela ye-SET-RIGHT. Okudingeka ukwenze nje ukuhlanganisa nokubopha izingxenye zomshini.
Zonke izilinganiso ezithinta ukuvuleka kwamabhereyitha esihlanganyelweni, njenge-bearing tolerances, ububanzi bangaphandle bomgodi, ubude bomgodi, ubude bendlu yamabhereyitha, kanye nobubanzi bangaphakathi bomgodi wamabhereyitha, zibhekwa njengeziguquguquko ezizimele lapho kubalwa amazinga okunokwenzeka. Esibonelweni esikuMfanekiso 7, zombili izindandatho zangaphakathi nezangaphandle zifakwe kusetshenziswa ukulingana okuvamile, futhi isivalo sokugcina simane siboshwe ekugcineni komgodi. s = (1316 x 10-6)1/2= 0.036 mm3s = 3 x 0.036=0.108mm (0.0043 in) 6s = 6 x 0.036= 0.216 mm (0.0085 inches) 99.73% wenhlangano (ububanzi bamathuba) isikhawu esingenzeka = 0.654 Ukuze uthole i-100% ye-mm (0.0257 inches) assembly (isibonelo), khetha i-0.108 mm (0.0043 inches) njengesikhala esimaphakathi. Ku-99.73% we-assembly, ububanzi bokuvuleka okungenzeka bungu-zero kuya ku-0.216 mm (0.0085 intshi). †Amasongo amabili angaphakathi azimele ahambisana ne-axial variable ezimele, ngakho-ke i-axial coefficient iphindwe kabili. Ngemva kokubala ububanzi bamathuba, ubude obujwayelekile bobukhulu be-axial budinga ukunqunywa ukuze kutholakale i-bearing clearance edingekayo. Kulesi sibonelo, zonke izilinganiso ngaphandle kobude bomgodi ziyaziwa. Ake sibheke ukuthi singabala kanjani ubude obujwayelekile bomgodi ukuze kutholakale i-bearing clearance efanele. Ukubalwa kobude bomgodi (ukubalwa kobukhulu obujwayelekile): B = A + 2C + 2D + 2E + F[ [2lapho: A = ububanzi obumaphakathi bendlu phakathi kwezindandatho zangaphandle = 13.000 mm (0.5118 amayintshi) B = isilinganiso sobude bomgodi (TBD) C = Ububanzi obumaphakathi bokuthwala ngaphambi kokufakwa = 21.550 mm (0.8484 amayintshi) D = Ububanzi obumaphakathi bokuthwala ngenxa yokulingana kwendandatho yangaphakathi* = 0.050 mm (0.0020 amayintshi) E = Ububanzi obumaphakathi bokuthwala ngenxa yokulingana kwendandatho yangaphandle* = 0.076 mm (0.0030 amayintshi) F = (kuyadingeka) imvume ejwayelekile yokuthwala = 0.108 mm (0.0043 amayintshi) * Kuguqulwe kwaba ukubekezelelana okulinganayo kwe-axial.
