I-roller chain yinxalenye yothumelo esetyenziswa kakhulu kwimveliso yemizi-mveliso. Ukusebenza kwayo kuxhomekeke kakhulu kwinkqubo yokwenziwa, kwaye inkqubo yokwenza i-carburing yeyona nto iphambili ekuphuculeni ukusebenza kwe-roller chain.
Inkqubo ye-carburizing ye-roller chain: isitshixo sokuphucula ukusebenza
I-roller chain yenza umsebenzi obalulekileyo wokuhambisa izixhobo ezahlukeneyo zoomatshini. Indawo yayo yokusebenza idla ngokuba nzima kwaye iyatshintshatshintsha, ijongene nemingeni efana nomthwalo onzima, ukuguguleka kunye nokudinwa. Ukuze ii-roller chain zikwazi ukuziqhelanisa ngcono nezi meko zinzima kwaye zandise ubomi bazo benkonzo, inkqubo yokufaka i-carburing ibe yinxalenye ebalulekileyo yenkqubo yokwenziwa kwee-roller chain.
Imigaqo esisiseko yenkqubo yokugabha
I-Carburizing yinkqubo yonyango lobushushu esetyenziswa kakhulu ukuphucula ubulukhuni, ukumelana nokuguguleka kunye nokumelana nokudinwa komphezulu wentsimbi ngelixa kugcinwa ubulukhuni obuhle kunye ne-plasticity yesiseko. Ngokukodwa, i-roller chain ibekwa kwindawo etyebileyo kwi-carbon medium, kwaye ii-athomu ze-carbon zifakwa kumphezulu we-roller chain kubushushu obuphezulu ukuze zenze umaleko we-carburised ene-carbon ephezulu. Njengoko ubushushu buncipha, olu maleko we-austenite ene-carbon ephezulu luya kuguqulwa lube yi-martensite enzima kakhulu, ngaloo ndlela kufezekiswa ukuqina komphezulu we-roller chain.
Iindlela eziqhelekileyo zenkqubo ye-carburizing ye-roller chain
Ukugalela igesi: Le yenye yezona ndlela zisetyenziswa kakhulu zokugalela igesi. Itsheyini yeroller ifakwa kwisithando somlilo esivaliweyo kwaye iarhente yokugalela igesi eyenziwe ikakhulu ziigesi ze-hydrocarbon ezifana ne-methane kunye ne-ethane ingeniswa. Kumaqondo obushushu aphezulu, ezi gesi ziyabola ukuze zivelise ii-athomu zekhabhoni ezisebenzayo, ngaloo ndlela zifezekisa ukugalela igesi. Iingenelo zokugalela igesi kukusebenza okulula, isantya sokufudumeza esikhawulezayo, umjikelo omfutshane wemveliso, kunye nokukwazi ukulungisa ngokuchanekileyo ubunzulu kunye noxinzelelo lomaleko we-carburing ngokulawula iiparameter ezifana nokwakheka kwegesi kunye nesantya sokuhamba. Umgangatho we-carburing uzinzile, okulula ukuwufezekisa ngokusebenza ngoomatshini nangokuzenzekelayo, okuphucula kakhulu iimeko zomsebenzi.
I-carburizing yolwelo: I-carburizing yolwelo kukuntywilisela i-roller chain kwi-liquid carburizing medium. Izixhobo ezisetyenziswa rhoqo ziquka i-silicon carbide, i-“603″ carburizing agent, njl. Kwiqondo lobushushu elifanelekileyo, ii-athomu zekhabhoni ziyanyibilika kwi-liquid medium zize zingene kumphezulu we-roller chain. Inzuzo ye-liquid carburizing kukuba umjikelo wemveliso umfutshane, kwaye ukucima kungenziwa ngqo emva kwe-carburizing ngaphandle kokukhathazeka malunga ne-oxidation kunye ne-decarburization. Ubushushu kunye nexesha kulula ukulawula, ukufudumala kuyafana, kwaye ukuguqulwa kwento yokusebenza kunokunciphisa ngempumelelo. Izixhobo nazo zilula. Nangona kunjalo, iimeko zokusebenza zazo zimbi kwaye zihlala zifanelekile kwimveliso yeqhekeza elinye okanye elincinci.
I-carburizing eqinileyo: Le yindlela yendabuko yokwenza i-carburizing. I-roller chain ifakwa kwibhokisi ye-carburizing evaliweyo kunye ne-agent ye-carburizing eqinileyo, kwaye emva koko ibhokisi ye-carburizing ifakwa kwisithando sobushushu kwaye ifudunyezwe kubushushu be-carburizing kwaye igcinwe ifudumele ixesha elithile, ukuze ii-athomu zekhabhoni ezisebenzayo zingene kumphezulu we-roller chain. I-agent ye-carburizing eqinileyo ngokubanzi yenziwe ngamalahle kunye nezinye izinto ezikhuthazayo. Iingenelo zale ndlela kukusebenza okulula, iimfuno zobugcisa eziphantsi, akukho mfuneko yezixhobo ezikhethekileyo, uluhlu olubanzi lwemithombo yee-agent ze-carburizing kwaye zinokulungiswa nguwe, kunye noluhlu olubanzi lwezicelo. Kodwa iingxaki nazo ziyabonakala. Umgangatho we-carburizing kunzima ukuwulawula ngokuchanekileyo, iimeko zokusebenza zimbi, amandla aphezulu, umjikelo wemveliso mde, iindleko ziphezulu, kwaye ukuthambekela kokukhula kwengqolowa kukhulu ngexesha lenkqubo yokwenza i-carburizing. Kwezinye izinto ezibalulekileyo zomsebenzi, ukucima ngokuthe ngqo akuqhelekanga ukusetyenziswa.
Izinto eziphambili zenkqubo ye-carburizing ye-roller chain
Ubushushu kunye nexesha le-carburizing: Ubushushu be-carburizing buhlala buphakathi kwe-900℃ kunye ne-950℃. Amaqondo obushushu aphezulu anokukhawulezisa izinga lokusasazwa kwee-athomu zekhabhoni kwaye anciphise ixesha le-carburizing, kodwa kwangaxeshanye anokubangela ukukhula kweenkozo kwaye achaphazele ukusebenza kwe-roller chain. Ixesha le-carburizing limiselwa ngokobunzulu be-carburizing layer efunekayo, idla ngokuqala kwiiyure ezimbalwa ukuya kwiiyure ezininzi. Umzekelo, kwezinye ii-roller chains ezifuna umaleko we-carburizing ongaphantsi, kungathatha iiyure ezimbalwa kuphela, ngelixa kwii-roller chains ezifuna umaleko we-carburizing onzulu, kungathatha iiyure ezininzi zexesha le-carburizing. Kwimveliso yokwenyani, kuyimfuneko ukumisela ubushushu be-carburizing obufanelekileyo kunye neeparameter zexesha ngokusebenzisa iimvavanyo kunye namava ngokusekelwe kwizinto ezifana nezinto ezithile, ubungakanani kunye neemfuno zokusebenza kwe-roller chain.
Ulawulo lwe-carbon potential: I-carbon potential ibhekisa kubuchule be-agent ye-carburizing yokubonelela ngee-athomu ze-carbon kumphezulu wesixhobo somsebenzi.

Ngokwesiqhelo, izixhobo ezifana nee-oxygen probes kunye nee-infrared gas analyzers zisetyenziselwa ukujonga umoya okwisithando ngexesha langempela, kwaye i-carbon potential ilungiswa ngexesha ngokweziphumo zokubeka esweni ukuqinisekisa ukuba i-carbon potential gradient isoloko ikuluhlu olufanelekileyo, ukuze kufunyanwe umaleko we-carburing ofanayo nowomgangatho ophezulu. Ukongeza, ngoncedo lwetekhnoloji yokulinganisa yekhompyutha ephucukileyo, imodeli yokusasazwa kwe-carbon potential inokusekwa ukuze ilingise utshintsho lwe-carbon potential gradient kunye nokuguquka komaleko we-carburing phantsi kweeparamitha ezahlukeneyo zenkqubo, iqikelele isiphumo se-carburing kwangaphambili, ibonelele ngesiseko sesayensi sokwenza ngcono inkqubo, kwaye iphucule ngakumbi ukuchaneka kunye nokuzinza kwenkqubo ye-carburing.
Ukupholisa nokucima: Emva kokufaka i-carburizing, i-roller chain idla ngokufuna ukupholiswa ngokukhawuleza nokucima ukuze kwenziwe isakhiwo se-martensitic kwaye kuphuculwe ubulukhuni bomphezulu. I-command eqhelekileyo yokucima iquka ioyile, amanzi, ulwelo lokucima i-polymer, njl. I-command eyahlukileyo yokucima i-oyile inezinga lokupholisa elahlukileyo kunye neempawu, kwaye kufuneka ikhethwe ngokufanelekileyo ngokweemfuno zezinto kunye nokusebenza kwe-roller chain. Umzekelo, kwezinye ii-roller chain ezincinci, i-oyile quenching ingasetyenziswa; kwi-roller chain ezinkulu okanye ii-roller chain ezineemfuno zobulukhuni obuphezulu, i-water quenching okanye i-polymer quenching liquid quenching ingasetyenziswa. Emva kokucima, i-roller chain ikwafuneka incitshiswe ukuze kususwe uxinzelelo lwangaphakathi oluveliswa ngexesha lenkqubo yokucima kwaye kuphuculwe ubulukhuni bayo. Ubushushu bokupholisa ngokubanzi buphakathi kwe-150℃ kunye ne-200℃, kwaye ixesha lokupholisa limiselwa ngokwezinto ezifana nobukhulu be-roller chain kunye nobushushu bokupholisa, ngokuqhelekileyo malunga neyure e-1 ukuya kwezi-2.
Ukukhethwa kwezinto zeroller chain kunye nokulungiswa kwenkqubo ye-carburizing
Izinto ezisetyenziswa kwi-roller chain zihlala ziyintsimbi ye-carbon ephantsi okanye i-carbon alloy steel ephantsi, njengentsimbi ye-20, i-20CrMnTi, njl. Ezi zinto zinobunkunkqele obuhle kunye nokuqina, kwaye zinokwenza umaleko we-carburised osemgangathweni ophezulu ngexesha le-carburizing. Ukuthatha i-20CrMnTi njengomzekelo, iqulethe izinto ezifana ne-chromium, i-manganese kunye ne-titanium. Ezi zinto ze-alloy azinakuphucula kuphela amandla kunye nokuqina kwentsimbi, kodwa zikwachaphazela nempembelelo yayo yokuqina ngexesha le-carburing. Ngaphambi kokuba i-carburing, i-roller chain kufuneka ilungiswe kakuhle, njengokucola okanye ukuqhumisa isanti, ukuze kususwe ii-oxides eziphezulu kunye nokungcola ukuqinisekisa inkqubela phambili egudileyo yenkqubo ye-carburing.
