Uma i-rolling bear ye-crankshaft yenjini ihluleka, izoba nomthelela ngqo esimweni sobuchwepheshe benjini. Ngakho-ke, kufanele kuqashelwe ukwehluleka kwe-rolling bear. Ukwehluleka okuvamile kwe-rolling bear manje kuhlaziywa ngale ndlela elandelayo: 1. Kukhona igebe phakathi kokunyakaza kwezindandatho zangaphakathi nangaphandle zokuthwala kanye nokugqokwa kwezingxenye zokukhwelana.

①. Iringi yangaphandle ye-bearing iyahamba. Ukuze kube lula ukuhlakazeka nokuhlanganisa, iringi yangaphandle yebheringi eginqikayo ithatha ukulingana kwesikhashana nembobo yesihlalo. Ukuphazamiseka okukhulu kweringi yangaphandle ye-bearing yangaphambili ngu-0.035mm, futhi imvume ephezulu ingu-0.013mm. Ukuphazamiseka okukhulu kweringi yangaphandle yebheringi yangemuva ngu-0.016mm, futhi imvume ephezulu ingu-0.06mm. Lapho uhlanganisa, imbobo yesihlalo kufanele ilinganiswe, futhi ukuphazamiseka kwayo noma imvume akufanele idlule ububanzi obungenhla, ngaphandle kwalokho imbobo yokuhlala kufanele ilungiswe.

②. Iringi yangaphakathi ye-bearing iyahamba. Iringi yangaphakathi ye-rolling bearing ithatha ukulingana kokuphazamiseka nejenali. Ukuphazamiseka okukhulu kobubanzi bangaphakathi be-bearing yangaphambili ngu-0.055mm, futhi ukuphazamiseka okuncane kungu-0.012mm. Ukuphazamiseka okukhulu kobubanzi bangaphakathi bebheringi yangemuva ngu-0.046mm, futhi ukuphazamiseka okuncane kungu-0.003mm. Kusukela kumbono wokuxhumana ongenhla, uma ukuthwala kuye kwahlakazwa futhi kwahlanganiswa izikhathi eziningana, kungase kube negebe phakathi kweringi yangaphakathi ye-bearing kanye nejenali, ijenali kufanele ilungiswe ngaphambi kokuba isetshenziswe.

Lapho ukulingana phakathi kwebheyili ne-shaft kuxega, ezinye izisebenzi zokunakekela zisebenzisa embossing noma ukubhoboza ingaphezulu le-shaft exegayo ukuze kuphendulwe ingaphezulu le-shaft ngomzamo wokuthola indawo eqinile elingana. Lokhu akubhubhisi nje kuphela ukuma kwejometri ye-shaft surface, kwenza i-bearing ingatholi indawo efanele yesikhungo ngesikhathi sokufakwa kanye ne-skews, kodwa futhi ingxenye e-fluffed ekugcineni izoba isicaba futhi ibe yinto ekhululekile. Indlela efanele yokulungisa ukugaya nokulungisa ijenali kuqala, bese uxubha noma ufutha ijenali.

2. Ikheji elithwalayo eliginqikayo ligugile, likhubazekile noma liphukile

①. Lapho uhlanganisa izindandatho zangaphakathi nangaphandle ze-rolling bearing, ngenxa yokuphazamiseka okukhulu, amabhola athwalayo anamathele endandeni yokuhlala, futhi i-cage yokuthwala igxiliwe kalula ngesikhathi sokusebenza. Ngakho-ke, ukulinganisa kufanele kwenziwe ngesikhathi sokuhlanganiswa ukuze kuqinisekiswe ukuphazamiseka okujwayelekile.

②. Ukugcotshwa kwe-crankshaft bearing kuwuhlobo lwe-splash. Lapho ukuthwala kuntuleka noma kungenawo amafutha okugcoba, ikakhulukazi lapho umthwalo osebenza ekuthwaleni mkhulu, izinga lokushisa elithwalayo liyakhuphuka. Ngokuvamile, izinga lokushisa leringi yangaphakathi yokuthwala licishe libe ngu-10°C ngaphezu kweringi yangaphandle. Ngenxa yokuthi ukunwetshwa okushisayo kwamasongo angaphakathi nangaphandle kuhlukile, igebe phakathi kwebhola nomzila womjaho liyanyamalala, futhi ikheji cishe lizompintsha lapho ukuthwala kusebenza. Ngakho-ke, lapho ufaka i-bearing, uwoyela wokugcoba ohlanzekile kufanele usetshenziswe emgwaqeni womjaho ukuvimbela uwoyela wokugcoba ukuba ungachaphazi futhi ubangele ukungqubuzana okomile.

3. Umjaho onamabhere aginqikayo kanye nokuxebuka kwendawo

①. Ukucwecwa okubangelwa umthwalo womthelela kanye nengcindezi eshintshanayo. Izinto ezigingqayo ze-bearing kanye nemigwaqo eyindandatho yangaphakathi neyangaphandle yonke ingaphansi kwemithwalo ye-cyclic pulsating, okuholela ekushintsheni kokucindezeleka kokuxhumana. Uma inani lemijikelezo yokucindezeleka lifinyelela inani elithile, ukuchitheka kokukhathala kwenzeka ezindaweni zokusebenza zezinto eziginqikayo noma imigwaqo eyindandatho yangaphakathi nangaphandle. Uma umthwalo othwalayo mkhulu kakhulu, lokhu kukhathala kuzokwanda. Ngaphezu kwalokho, uma i-bearing ifakwe ngokungalungile futhi i-shaft igobile, umgwaqo womjaho ungase uqhume. I-flywheel kanye ne-pulley yenjini ifakwe ama-counterweights, futhi umzuzu wokujikeleza we-inertia okhiqizwayo ulinganiswa nomzuzu wokuzungeza we-inertia okhiqizwa ingxenye ejikelezayo yenjini. Uma umzuzu okhiqiziwe we-inertia ungalingani, injini izodlidliza kakhulu ngemva komlilo, okuzokwandisa inani lokushintshana kokucindezeleka nemijikelezo yokucindezeleka, okubangele umgwaqo womjaho kanye nezinto eziginqikayo ukuthi zixebuke ngaphambi kwesikhathi.

Ukuze ugweme ukusakazeka endaweni yomjaho kanye nezinto eziginqikayo, umthwalo owengeziwe kanye nokudlidliza okungadingekile kufanele kugwenywe ngesikhathi sokusetshenziswa, i-throttle nesivinini kufanele kusetshenziswe ngendlela efanele ngesikhathi sokusebenza ukuze kuvinjwe ugandaganda ukuthi ungaqhuzuki, namabhawodi omzimba angashintshi ihlolwe kaningi ukuvimbela ukuxega .

②. Ngenxa yokuthi izinhlayiya eziqinile zangaphandle ziwela endaweni ehambisanayo yegobolondo noma phakathi kwendawo ehambisanayo ye-shaft nendandatho, ukuma komzila womjaho kuhlanekezelwe. I-elementi eginqikayo ibeka ingcindezi enkulu lapha, okuholela ekugugeni okusheshayo nokuxebuka kwensimbi komjaho weringi. I-Rolling bearing iyingxenye enembe kakhulu, ezwela kakhulu endabeni yangaphandle. Enqubweni yokulungisa, sebenzisa indwangu yokwesula ehlanzekile, engafakwanga emgqeni. Indwangu ye-wiper akumele ithathelwe indawo ngentambo kakotini endala, ngoba intambo iphetha ngentambo kakotini endala ixubene kalula emafutheni okugcoba bese ifaka i-bearing, eyingozi kakhulu. Ngaphambi kokuhlanganisa, hlanza kahle ijenali, imbobo yokuhlala, nendandatho yangaphakathi nengaphandle yeringi ukuze uvimbele ukungcola ekungeneni endaweni yokukhwelana.

③. Umonakalo odalwe ukulimala komzila womjaho ngesikhathi sokufakwa. Uma ngesikhathi sokufakwa, ingcindezi esetshenzisiwe idluliselwa ngendandatho yangaphandle kanye nebhola lensimbi, nakanjani izobangela imigodi engxenyeni lapho umjaho wendandatho uthintana nebhola lensimbi. I-bear yahlubuka futhi yaqedwa ngesikhathi esifushane. Ngakho-ke, amathuluzi akhethekile kufanele asetshenziswe lapho kuhlakazwa, futhi izingxenye ezithwala amandla kufanele zilungile futhi zilingane.

4. Ukucaciswa kwe-radial kanye ne-axial ye-bearing kuyanda

Ukucaciswa kwe-radial kanye ne-axial kwama-bearings kuyanda, ngaphandle kokungqubuzana okomile nokungqubuzana okukhulu nokuguga ngesikhathi sokuqala. Ngokuyinhloko kubangelwa ukungqubuzana phakathi kwezinhlayiya zensimbi ebusweni bezingxenye kanye nesihlabathi, uthuli nokungcola kumafutha okugcoba ezintweni ezigoqayo kanye nemigwaqo yomjaho.

I-bearing inokwenyuka okuphawulekayo kokuvunyelwa phakathi kwendandatho nezinto eziginqikayo ngenxa yokugqoka kwe-abrasive, indawo ye-matte yenziwe emgwaqeni womjaho, futhi kuvele izimpawu zokuklwebheka ezingalingani. Indlela yokuvimbela iwukuba esikhundleni sikawoyela wokugcoba ngesikhathi, futhi imbobo yokugcoba kufanele ingangeni moya ukuze kuvinjelwe ukungena kokungcola.
