Ukunwaya okwenzeka kububanzi obungaphandle bezinto ezigoqayo: amadents ayisiyingi endaweni yokuxhumana yezinto ezigoqekayo.Ngokuvamile kukhona imikhondo ye-circumferential ehambisanayo kuma-roller, bheka Umfanekiso 70 kanye no-71, futhi into ethi "hairball" ivame ukuba khona kumabhola, bheka Umfanekiso 72. Akufanele kudidaniswe nokulandela onqenqemeni (bona isigaba 3.3.2.6).Unqenqema lwethrekhi olwakhiwe unqenqema olugijima lubushelelezi ngenxa yokuguqulwa kwepulasitiki, kuyilapho ukuklwejwa kunemiphetho ebukhali.Izinhlayiya eziqinile zivame ukushumeka emaphaketheni ekheji, zibangele umunyu, bheka uMdwebo 73. Imbangela: Isithambisi esingcolile;izinhlayiya eziqinile ezishumekwe emaphaketheni ekheji zisebenza njengezinhlayiya ezilumayo esondo lokugaya Ikhambi: - liqinisekisa izimo zokufaka ezihlanzekile - lithuthukisa ukuvala - lihlunga i-lubricant.

Isenzakalo samamaki ashelelayo: izinto ezigingqayo ziyashelela, ikakhulukazi amarola amakhulu nasindayo, njengamabheringi e-INA agcwalisayo.Slip roughens imigwaqo yomjaho noma izinto eziginqikayo.Impahla ivamise ukwakha ngezimpawu zokudonsa.Ngokuvamile awasatshalaliswanga ngokulinganayo phezulu kodwa emabala, bheka uMdwebo 74 no-75. Imigodi emincane ivame ukutholakala, bheka isigaba 3.3.2.1 “Ukukhathala ngenxa yokungagcotshisi kahle”.Izimbangela: - Uma umthwalo uphansi kakhulu futhi ukugcotshwa kukubi, izinto eziginqikayo ziyashibilika emijahweni.Ngezinye izikhathi ngenxa yokuthi indawo yokuthwala incane kakhulu, ama-roller anciphisa ngokushesha emaphaketheni ekheji endaweni engalayishiwe, bese esheshisa kakhulu lapho engena endaweni yokuthwala.- Izinguquko ezisheshayo ngesivinini.Izinyathelo zokulungisa: - Sebenzisa ama-bearings anomthamo ophansi womthwalo - Layisha ngaphambili ama-bearings, isb. ngeziphethu - Yehlisa ukudlala okudlalayo - Qinisekisa ukuthi umthwalo owanele noma ungenalutho - Thuthukisa ukuthambisa

Ukunwaya okwenzekayo: Kumabhere angama-cylindrical roller ahlukanisekayo noma ama-roller ama-tapered, ama-elementi aginqikayo kanye nemigwaqo yomjaho ayinayo into ehambisana ne-eksisi kanye ne-equidistant kusuka kuma-elementi agingqayo.Kwesinye isikhathi kuba khona amasethi amaningana amamaki esiqondisweni se-circumferential.Lo mkhondo uvame ukutholakala kuphela endaweni eyindilinga cishe engu-B/d kuneseyingi yonke, bheka uMfanekiso 76. Imbangela: Ukungaboni ngaso linye kanye nokuhlikihlana lapho ufaka i-ferrule eyodwa kanye ne-ferrule enezinto ezigingqayo.Kuyingozi kakhulu uma uhambisa izingxenye zesisindo esikhulu (lapho i-shaft ewugqinsi enendandatho yangaphakathi eveza indandatho kanye nomhlangano wesici esigoqayo iphushwa eringini yangaphandle esivele ifakiwe endlini yokuthwala).Ikhambi: - Sebenzisa amathuluzi okufaka afanelekile - Gwema ukungahambi kahle - Uma kungenzeka, jika kancane lapho ufaka izinto.
