Amaketanga e-roller ayisici esibalulekile ezinhlotsheni ezahlukene zezimboni, okuhlanganisa imishini yokukhiqiza, yezolimo neyezimoto. Lawa maketanga aklanyelwe ukudlulisa amandla ngendlela ephumelelayo nethembekile, abalulekile ekusebenzeni kahle kwemishini nemishini. Kodwa-ke, ukuqinisekisa ukuthi ihlala isikhathi eside futhi isebenza kahle, amaketanga e-roller kumele adlule enkambisweni yokwelashwa ngokushisa ukuze andise ukuqina kwawo namandla awo.
Ukwelashwa ngokushisa kuyisinyathelo esibalulekile ekukhiqizweni kwe-roller chain njengoba kungathuthukisa kakhulu izakhiwo zemishini ye-roller chain kanye nokumelana kwayo nokuguguleka nokukhathala. Ngokubeka i-chain enkambisweni yokushisa nokupholisa elawulwayo, isakhiwo sezinto ezibonakalayo singashintshwa ukuze kuthuthukiswe ubulukhuni, ukuqina kanye nokusebenza okuphelele. Lesi sihloko sizobheka ngokujulile ukubaluleka kokwelashwa ngokushisa ekwandiseni ukuqina kwe-roller chain kanye namasu ahlukahlukene ahilelekile kule nqubo.
Inhloso eyinhloko yokwelashwa kokushisa kwe-roller chain ukufeza ibhalansi efanele yokuqina kwezinto nokuqina. Lokhu kufezwa ngochungechunge lwemijikelezo yokushisa nokupholisa elawulwa ngokucophelela eyenzelwe ukushintsha isakhiwo se-microchain ezingeni le-athomu. Amasu avame kakhulu okwelapha ukushisa kwama-roller chain afaka phakathi ukucima nokushisa, i-carburizing kanye nokuqina kwe-induction.
Ukucima nokulungisa kuyinqubo yokwelapha ukushisa esetshenziswa kabanzi kumaketanga ajikelezayo. Kufudumeza iketanga liye ekushiseni okuthile bese liphola ngokushesha endaweni yokucima njengamafutha noma amanzi. Lokhu kupholisa okusheshayo kudala isakhiwo esiqinile esikhuphula ubulukhuni bomphezulu kanye nokumelana nokuguguleka kweketanga. Iketanga libe seliqiniswa ngokulifudumeza liye ekushiseni okuphansi, okunikeza ukuqina kweketanga futhi kunciphise ukucindezeleka kwangaphakathi, ngaleyo ndlela kwandise ukuqina kwalo okuphelele.
I-Carburizing ingenye indlela ephumelelayo yokwelapha ukushisa yamaketanga ajikelezayo, ikakhulukazi ekusetshenzisweni okudinga ubulukhuni obuphezulu bomphezulu kanye nokumelana nokuguguleka. Ngesikhathi senqubo ye-carburizing, iketanga livezwa emoyeni ocebile nge-carbon emazingeni okushisa aphezulu, okuvumela ama-athomu e-carbon ukuthi asakazeke engxenyeni engaphezulu yezinto ezibonakalayo. Lokhu kuphumela egobolondweni langaphandle eliqinile elinomongo oqinile, okunikeza ukumelana nokuguguleka okuhle kakhulu nokukhathala ngenkathi kugcinwa amandla aphelele eketanga.
Ukuqina kokungeniswa kuyindlela ekhethekile yokwelapha ukushisa evame ukusetshenziselwa ukuqinisa izindawo ezithile zamaketanga okugoqa, njengezindawo ezithwala umthwalo kanye nezindawo zokuxhumana. Kule nqubo, ukushisa kokungeniswa okuvame kakhulu kusetshenziswa ukushisa ngokushesha indawo eqondiwe, bese iqedwa ukuze kufezwe ubulukhuni obufunwayo. Ukuqina kokungeniswa kuvumela ukulawula okunembile kokujula kokucima futhi kunciphisa ukuguquguquka, okwenza kube kuhle kakhulu ekuthuthukiseni ukuqina kwezingxenye ezibalulekile ngaphakathi kwamaketanga okugoqa.
Ngaphezu kwalezi zindlela zokwelapha ukushisa, ukukhethwa kwezinto kudlala indima ebalulekile ekwandiseni ukuqina kweketanga lama-roller. Izinsimbi ze-alloy ezisezingeni eliphezulu, njenge-4140, 4340 kanye ne-8620, zivame ukusetshenziswa ukukhiqiza amaketanga ama-roller ngenxa yokuqina kwawo okuhle kakhulu. Lezi zinto zifaneleka kahle ezinqubweni zokwelapha ukushisa futhi ziyakwazi ukufeza izakhiwo ezidingekayo zemishini, ezibalulekile ekumelaneni nezimo zokusebenza ezinzima ezibhekene namaketanga ama-roller.
Ukwandisa ukuqina kweketanga lama-roller ngokwelashwa ngokushisa akugcini nje ngokwandisa isikhathi salo sokusebenza, kodwa futhi kusiza ekuthuthukiseni ukusebenza kahle kanye nokuthembeka kwemishini esetshenziswa kuyo. Amaketanga ama-roller aphathwe kahle ngokushisa anikeza ukuguguleka okuphezulu, ukukhathala kanye nokumelana nokugqwala, kunciphisa izidingo zokulungisa kanye nesikhathi sokungasebenzi ngenkathi kuqinisekiswa ukusebenza okuqhubekayo ezindaweni zezimboni ezidinga kakhulu.
Ngamafuphi, ukwelashwa ngokushisa kuyisici esibalulekile ekwandiseni ukuqina kweketanga lama-roller. Ngokubeka iketanga ezinqubweni ezikhethekile zokwelashwa ngokushisa njengokushisa, i-carburizing, kanye nokucima ukungeniswa, izakhiwo zemishini zeketanga zingathuthukiswa kakhulu, ngaleyo ndlela kuthuthukiswe ubulukhuni, ukuqina, kanye nokumelana nokuguguleka. Kuhlanganiswe nokusetshenziswa kwensimbi ye-alloy esezingeni eliphezulu, ukwelashwa ngokushisa kudlala indima ebalulekile ekuqinisekiseni impilo yesevisi kanye nokuthembeka kwamaketanga ama-roller ezinhlotsheni ezahlukahlukene zezimboni. Ngakho-ke, abakhiqizi kanye nabasebenzisi bokugcina kufanele babeke phambili ekusebenziseni imikhuba efanele yokwelashwa ngokushisa ukuze kuthuthukiswe ukusebenza nokuqina kwamaketanga ama-roller emishinini nasemishinini yabo.
