Isenzeko somkrwelo kububanzi obungaphandle bezinto eziqengqelekayo: iidents ezijikelezayo kwindawo yokunxibelelana yezinto eziqengqelekayo.Ngokuqhelekileyo kukho ukulandelelana okujikelezayo okujikelezayo kwii-roller, jonga i-Figure 70 kunye ne-71, kunye ne-"hairball" isenzeko sihlala sikhona kwiibhola, jonga uMzobo 72. Akufunekanga udideke kunye ne-edge traces (jonga icandelo 3.3.2.6).Umda womzila owenziwe ngumphetho ohambayo uhamba kakuhle ngenxa yokuguqulwa kweplastiki, ngelixa i-scratch inamacangca abukhali.Amasuntswana aqinileyo ahlala efakwe kwiipokotho zekheji, ebangela ukubetha, jonga uMfanekiso 73. Unobangela: I-lubricant engcolisekileyo;amasuntswana aqinileyo afakwe kwiipokotho zekheji asebenza njengamasuntswana abrasive kwivili lokusila I-Remedy: - iqinisekisa iimeko zokufakela ezicocekileyo - ziphucula ukutywinwa - zihluza i-lubricant.

Isenzeko samanqaku e-Slip: izinto eziqengqelekayo ziyatyibilika, ngakumbi iirola ezinkulu nezinzima, ezinjengeebheringi ze-INA ezincedisana ngokupheleleyo.I-Slip i-roughens kwiindlela zomdyarho okanye izinto eziqengqelekayo.Izinto eziphathekayo zihlala zisakha kunye namanqaku okutsala.Ngokuqhelekileyo ayisasazwanga ngokulinganayo kumphezulu kodwa kumabala, jonga iSazobe 74 kunye no-75. Ukugatywa kwemingxuma emincinci kukholisa ukufunyanwa, jonga kwicandelo 3.3.2.1 “Ukudinwa ngenxa yokungathanjiswa kakuhle”.Izizathu: -Xa umthwalo uphantsi kakhulu kwaye ukuthambisa kukwimeko embi, izinto eziqengqelekayo ziyatyibilika kwiindlela zomdyarho.Ngamanye amaxesha ngenxa yokuba indawo yokuthwala incinci kakhulu, i-roller iyancipha ngokukhawuleza kwiipokethi ze-cage kwindawo engalayishiyo, kwaye ikhawuleza ngokukhawuleza xa ingena kwindawo yokuthwala.-Utshintsho olukhawulezayo kwisantya.Amanyathelo okulungisa: – Sebenzisa iibheringi ezinomthwalo ophantsi umthamo – Layisha kwangaphambili iibheringi, umz. ngemithombo – Nciphisa umdlalo odlalayo – Qinisekisa umthwalo owaneleyo nokuba ungenanto – Phucula ukuthambisa

I-Bearing scratching phenomenon: Kwiibheringi ze-cylindrical roller ezihlukeneyo okanye iibheringi ze-tapered roller, izinto eziqengqelekayo kunye neendlela zomdyarho azikho izinto ezihambelana ne-axis kunye ne-equidistant ukusuka kwizinto eziqengqelekayo.Ngamanye amaxesha kukho iiseti ezininzi zamanqaku kwicala le-circumferential.Lo mkhondo udla ngokufunyanwa kuphela kwicala le-circumferential malunga ne-B/d kune-circumference yonke, jonga uMfanekiso 76. Isizathu: Ukungalungelelani kakuhle kunye nokuhlikihla omnye komnye xa ufaka i-ferrule enye kunye ne-ferrule enezinto ezijikelezayo.Kuyingozi ngakumbi xa kushukunyiswa amacandelo obunzima obukhulu (xa i-shaft eshinyeneyo eneringi yangaphakathi ethwele kunye nendibano yento eqengqelekayo ityhalelwa kwiringi yangaphandle esele ifakiwe kwizindlu zokuthwala).Unyango: -Sebenzisa izixhobo zofakelo ezifanelekileyo-Kunqande ukungahambi kakuhle-Ukuba kunokwenzeka, jika kancinci xa ufaka izinto.
