Iiroller chain ziyinxalenye ebalulekileyo kwiintlobo ngeentlobo zezicelo zoshishino, kuquka ukwenziwa kwemveliso, oomatshini bezolimo kunye neemoto. Ezi roller chain zenzelwe ukudlulisa amandla ngokufanelekileyo nangokuthembekileyo, zibalulekile ekusebenzeni kakuhle kwezixhobo kunye noomatshini. Nangona kunjalo, ukuqinisekisa ukuba zihlala ixesha elide kwaye zisebenza, iiroller chain kufuneka zidlule kwinkqubo yonyango lobushushu ukuze ziqine kwaye ziqine ngakumbi.
Unyango lobushushu linyathelo elibalulekileyo ekwenzeni iiroller chain njengoko lunokuphucula kakhulu iipropati zoomatshini zeroller chain kunye nokumelana kwayo nokudinwa. Ngokubeka iroller kwinkqubo yokufudumeza nokupholisa elawulwayo, ulwakhiwo lwesixhobo lunokutshintshwa ukuphucula ubulukhuni, ukuqina kunye nokusebenza ngokubanzi. Eli nqaku liza kujonga ngokunzulu ukubaluleka konyango lobushushu ekwandiseni ukuqina kweeroller chain kunye neendlela ezahlukeneyo ezibandakanyekayo kule nkqubo.
Eyona njongo iphambili yonyango lobushushu be-roller chain kukufezekisa ibhalansi efanelekileyo yobunzima kunye nokuqina kwezinto. Oku kufezekiswa ngothotho lwemijikelo yokufudumeza kunye nokupholisa elawulwa ngononophelo eyenzelwe ukutshintsha isakhiwo se-microstructure ye-chain kwinqanaba le-athomu. Iindlela eziqhelekileyo zonyango lobushushu kwi-roller chain ziquka ukucima kunye nokushisa, i-carburizing kunye nokuqinisa i-induction.
Ukucima nokulungisa yinkqubo yonyango lobushushu esetyenziswa kakhulu kwiityathanga eziqengqelekayo. Ifudumeza itsheyini ukuya kubushushu obuthile ize emva koko iyipholise ngokukhawuleza kwindawo yokucima efana neoyile okanye amanzi. Oku kupholisa ngokukhawuleza kudala isakhiwo esiqinileyo esongeza ubulukhuni bomphezulu kunye nokumelana nokuguguleka kwetsheyini. Emva koko itsheyini iyathomalaliswa ngokuyifudumeza kwakhona ukuya kubushushu obuphantsi, nto leyo enika ubulukhuni betsheyini kwaye inciphise uxinzelelo lwangaphakathi, ngaloo ndlela yonyusa ukuqina kwayo iyonke.
I-Carburizing yenye indlela esebenzayo yokunyanga ubushushu kwiitsheyini eziqengqelekayo, ingakumbi kwiimfuno ezifuna ubulukhuni obuphezulu bomphezulu kunye nokumelana nokuguguleka. Ngexesha lenkqubo ye-carburizing, itsheyini ivezwa kwindawo etyebileyo kwi-carbon-rich at high heavy, nto leyo evumela ii-athomu ze-carbon ukuba zisasazeke kumaleko womphezulu wezinto. Oku kubangela ukuba iqokobhe langaphandle eliqinileyo elinomongo oqinileyo, libonelela ngokumelana nokuguguleka okuhle kakhulu kunye nokudinwa ngelixa ligcina amandla alo lonke itsheyini.
Ukuqina kwe-induction yindlela ekhethekileyo yokunyanga ubushushu edla ngokusetyenziswa ukuqinisa iindawo ezithile zee-roller chain, ezifana neendawo ezithwala umthwalo kunye neendawo zokunxibelelana. Kule nkqubo, ukufudumala kwe-induction okuphindaphindekayo kusetyenziswa ukufudumeza ngokukhawuleza indawo ekujoliswe kuyo, emva koko icinywe ukuze kufezekiswe ubunzima obufunekayo. Ukuqina kwe-induction kuvumela ulawulo oluchanekileyo lobunzulu bokucima kwaye kunciphisa ukuguquguquka, okwenza kube yinto efanelekileyo yokuphucula ukuqina kwezinto ezibalulekileyo kwii-roller chain.
Ukongeza kwezi ndlela zonyango lobushushu, ukukhethwa kwezinto kudlala indima ebalulekileyo ekwandiseni ukuqina kwetyathanga le-roller. Iintsimbi ze-alloy ezikumgangatho ophezulu, ezifana ne-4140, 4340 kunye ne-8620, zihlala zisetyenziselwa ukwenza iityathanga ze-roller ngenxa yokuqina kwazo okugqwesileyo kunye namandla. Ezi zinto zilungele kakuhle iinkqubo zonyango lobushushu kwaye ziyakwazi ukufezekisa iipropati zoomatshini ezifunekayo, ezibalulekileyo ukumelana neemeko ezinzima zokusebenza ezifunyanwa ziityathanga ze-roller.
Ukwandisa ukuqina kwetyathanga le-roller ngonyango lobushushu akupheleli nje ekwandiseni ubomi balo benkonzo, kodwa kukwanceda ekuphuculeni ukusebenza kakuhle kunye nokuthembeka koomatshini elisetyenziswa kubo. Ityathanga le-roller eliphathwe kakuhle libonelela ngokuguguleka okuphezulu, ukudinwa kunye nokumelana nokugqwala, kunciphisa iimfuno zokugcinwa kunye nexesha lokungasebenzi ngelixa kuqinisekiswa ukusebenza rhoqo kwiindawo zoshishino ezifuna amandla.
Ngamafutshane, unyango lobushushu luphawu oluphambili ekwandiseni ukuqina kwetyathanga le-roller. Ngokubeka ityathanga kwiinkqubo zonyango lobushushu ezikhethekileyo ezifana nokushisa, i-carburizing, kunye nokucima i-induction, iipropati zoomatshini zetyathanga zinokuphucuka kakhulu, ngaloo ndlela ziphucula ubulukhuni, ukuqina, kunye nokumelana nokuguguleka. Xa zidityaniswe nokusetyenziswa kwentsimbi ye-alloy esemgangathweni ophezulu, unyango lobushushu ludlala indima ebalulekileyo ekuqinisekiseni ubomi benkonzo kunye nokuthembeka kwetyathanga le-roller kwizicelo ezahlukeneyo zoshishino. Ke ngoko, abavelisi kunye nabasebenzisi bokugqibela kufuneka babeke phambili ukuphumeza iindlela ezifanelekileyo zonyango lobushushu ukuze kuphuculwe ukusebenza kunye nokuqina kwetyathanga le-roller kwimishini nakwizixhobo zabo.
