Phenomenon (1): Txawv loads yuav tshwm sim nyob rau hauv ntau hom ntawm dov bearing kev puas tsuaj nyob rau hauv lub tsis zoo lubrication.Thaum lub load tsawg thiab muaj slippage, nplua daim tawv nqaij peeling tshwm sim.Vim tias lawv muaj ntau heev thiab zoo li lub qhov hauv qhov kev sib tw.Peb siv pitting los piav txog nws.Thaum lub load loj thiab lubricating roj zaj duab xis ua nyias, xws li dej nkag, thaum lub raceway polished nyob rau hauv siab, lub plhaub-zoo li tus dimples yuav tshwm.Thaum lub load yog siab thiab lub lubrication yog tsis zoo, yuav muaj ib tug heev pronounced rhuab cheeb tsam ntawm lub raceway, thiab tom qab kev khiav hauj lwm txuas ntxiv, thawj kab nrib pleb yuav tshwm sim.Ua rau: - Lubrication tsis zoo vim yog: • Cov roj nplua nyeem tsis txaus • Kev khiav hauj lwm kub siab dhau • Cov dej nkag ua rau muaj kev sib txhuam ntau dhau thiab cov khoom siv kev ntxhov siab rau ntawm qhov chaw sib tw - Qee lub sij hawm muaj kev daws teeb meem: - Ua kom muaj roj nplua nyeem - Siv cov roj nplua nyeem siab viscosity thiab kuaj EP additives nyob qhov twg los tau – Txias lubricants/bearings – softer greases yog hais tias ua tau – Tiv thaiv dej ingress • nkees vim hnav.

Phenomenon (2): Piv txwv li, muaj spalling ntawm dov cov ntsiab lus ntawm tapered roller bearings.ribbon khiav.Yog vim li cas: Vim tias cov khoom sib kis ntawm cov roj nplua nyeem, xws li kev nkag mus ntawm cov khoom txawv teb chaws vim kev foob tsis ua haujlwm, cov khoom siv bearing tau hnav nyob rau hauv qhov chaw sib cuag thiab cov geometry ntawm cov khoom hloov.Ib feem ntawm qhov tshwm sim ntawm lub zos overloading kuj muaj feem xyuam rau kev hloov tsis raug ntawm tapered roller bearings.Kev ntsuas kev kho mob: - Kev hloov pauv raws sij hawm ntawm cov roj nplua nyeem - Lim roj - Txhim kho cov ntsaws ruaj ruaj - Kev hloov cov ntsaws ruaj ruaj raws sij hawm - Kev kho cua sov tshwj xeeb ntawm cov nplhaib thiab cov chais • Kev qaug zog los ntawm cov pob txha ntawm cov txheej tawv tawv.

Phenomenon (3): Qhov chaw-hardened bearing qhov chaw muaj cov khoom loj ntawm txoj kev sib tw tawm.Ua rau: - Kev tawg lossis kev sib cais ntawm cov txheej tawv tawv - Kev thauj khoom ntau dhau lossis qhov tob tsis txaus ntawm cov txheej txheem tawv tawv rau cov khoom thauj, xws li vim kev tsim khoom tsis raug kho: - Kho qhov tob ntawm txheej hardened rau cov khoom thauj - Tsis txhob overloading rau Kev tshem tawm Cov Kabmob Kev Ntsuam Xyuas Kev Ua Haujlwm ntawm Kev Ua Haujlwm thiab Kev Puas Tsuaj Rolling Hu Rau Hom 51: Hnav hauv ntau qhov chaw tuaj yeem hloov pauv geometry ntawm qhov chaw sib cuag mus rau qhov chaw uas overloading hauv zos ua rau qaug zog tsis ua haujlwm.
