Ukuthwala Ukwehluleka Ukukhathala: Ukuthi Ukucindezeleka Kokuxhumana Kwe-Rolling Kuholela Kanjani Emifantuni Ne-Spalling

Ukwehluleka ukukhathala kuseyimbangela ehamba phambili yokulimala ngaphambi kwesikhathi, okubangela ukwehluleka okungaphezulu kwama-60% ezimbonini. Ama-element bearings—okuhlanganisa iringi yangaphakathi, iringi yangaphandle, izakhi ezigoqayo (amabhola noma ama-roller), kanye nekheji—isebenza ngaphansi kokulayishwa kwe-cyclic, ngezinto ezigingqayo ngokuqhubekayo zidlulisela amandla phakathi kwamasongo.

Ngenxa yendawo encane yokuxhumana phakathi kwezinto ezigoqayo kanye nemigwaqo yomjaho, umphumelaUkucindezeleka kokuxhumana no-Hertzianiphezulu kakhulu, ikakhulukazi ngaphansi kwezimo zejubane eliphezulu noma zomthwalo osindayo. Le ndawo yokucindezeleka egxilile iholelaukukhathala kokucindezeleka, okubonakala njengokugoba phezulu, ukuqhekeka, futhi ekugcineni ukuqhekeka.

Kuyini Ukukhathala Kokucindezeleka?

Ukukhathala kokucindezeleka kubhekisela kuukulimala kwesakhiwo okwenziwe kwasendaweniokubangelwa ukulayisha okuphindaphindiwe komjikelezo ngezansi kwamandla okugcina aqinile wento. Ngenkathi ingxenye enkulu yeukuzalaihlala ikhubazekile ngokunwebeka, izindawo ezincane kakhulu zithola ukuwohloka kwepulasitiki ngokuhamba kwesikhathi, ekugcineni kuqale ukwehluleka. Inqubo ivamise ukuvela ngezigaba ezintathu eziqhubekayo:

1. Ukuqaliswa kwe-Microcrack

• Kuvela kumazinga angaphansi komhlaba (0.1–0.3 mm ngaphansi kwendawo yomjaho).

• Kubangelwa ukugxila kokucindezeleka okujikelezayo kokungapheleli kwe-microstructural.

2. Ukusakazwa koMfantu

• Imifantu ikhula kancane kancane ezindleleni zokucindezela okukhulu kwe-shear.

• Ithonywe ukukhubazeka kwezinto kanye nemijikelezo yokulayisha yokusebenza.

3. Ukuphuka Kokugcina

• Ukulimala kwendawo kubonakala njengespalling or umgodi.

• Uma imifantu ifinyelela usayizi obalulekile, izinto ezibonakalayo ziyahlukana ukusuka phezulu.

Ukucabangela Ukukhathala Kwezimoto zikagesi Ezisindayo

In izimoto ezinkulu zempahla (LGVs)futhiizimoto zezimpahla ezisindayo(ama-HGV)-ikakhulukazi izinhlobonhlobo zikagesi-ukumelana nokukhathala kubaluleke kakhulu ngenxa:

• Ububanzi be-RPM ebanzi: Amamotho kagesi asebenza kumabhendi esivinini abanzi kunezinjini ezivuthayo, akhulisa amaza okulayisha ama-cyclic.

• Okukhiphayo kweTorque Ephakeme: Ukudluliswa kwe-torque esindayo kudinga ama-bearings anamandla okukhathala athuthukisiwe.

• Umthelela Wesisindo Sebhethri: Isisindo esingeziwe samabhethri e-traction siphakamisa ingcindezi ezingxenyeni ze-drivetrain, ikakhulukaziamasondo nama-motor bearings.

Abanikeli Ababalulekile Ekukhathaleni Kwengcindezi

√ Imithwalo Eshintshanayo

Ama-Bearings kumasistimu aguquguqukayo ahlala evezwa kokuhlukahlukaimithwalo ye-radial, axial, negobayo. Njengoba ama-elementi ajikelezayo ezungeza, ingcindezi yokuxhumana iyashintsha ngokujikeleza, idale ukugxila okuphezulu kwengcindezi ngokuhamba kwesikhathi.

√Ukukhubazeka Okubalulekile

Okufakiwe, ama-micro-cracks, nama-voids ngaphakathi kwempahla ethwalayo kungenza njengeama-concentrators wokucindezeleka, ukusheshisa ukuqala kokukhathala.

√Ukugcotshwa Okungalungile

Ukuthambisa okunganele noma okonakele kuyenyukaukungqubuzana nokushisa, ukunciphisa amandla okukhathala nokusheshisa ukuguga.

√Ukufakwa Okungalungile

Ukungaqondi kahle, ukulingana okungalungile, noma ukuqinisa ngokweqile phakathi nokufakwa kungase kungenise ingcindezi engalindelekile, kubeke engcupheni ukusebenza okuphathekayo.

Ukuqonda nokunciphisa ukukhathala kwengcindezi kubalulekile ekuqinisekiseni impilo ende yesevisi ezicelweni ezifunayo—ikakhulukazi izimoto ezisebenza ngogesi ezisindayo. Nakuba ukuthuthuka kwezinto zokwakha kanye nobuchwepheshe bokulingisa kuthuthukise ukumelana nokukhathala, kufaneleukukhetha, ukufakwa, nokugcinwazisabalulekile ekusebenzeni nasekuthembekeni.
