Umahluko oPhambili phakathi kokucima kunye nokunciphisa amandla kwi-Roller Chain Manufacturing: Kutheni le nkqubo zimbini zimisela ukusebenza kwe-Chain?
Kwimveliso yeeroller chain, iinkqubo zonyango lobushushu zibalulekile kumgangatho wemveliso kunye nobomi benkonzo. Ukucima kunye nokushisa, njengeendlela ezimbini ezisisiseko kunye neziphambili zonyango lobushushu, zikhankanywa rhoqo ngabathengi, kodwa uninzi lwabo alunalo ulwazi olupheleleyo ngomahluko wabo kunye nempembelelo esebenzayo. Eli nqaku liza kujonga umahluko obalulekileyo phakathi kokucima kunye nokushisa, kunye nendlela ezisebenzisana ngayoikhonkco lerolaimveliso, ukunceda abathengi bavavanye ngokuchanekileyo ukusebenza kwemveliso kwaye bakhethe ikhonkco le-roller elihlangabezana neemfuno zabo.
1. Inkqubo Ebalulekileyo: Ukuqonda Umahluko Ophambili Phakathi Kweenkqubo Ezimbini Kwimbono Yemolekyuli
Umahluko ophambili phakathi kokucima kunye nokulungisa ubushushu usekwe kwiindlela ezahlukeneyo ezitshintsha ngazo ulwakhiwo lwemolekyuli yezinto zesinyithi, ezimisela ngokuthe ngqo indlela ezichaphazela ngayo ukusebenza kwe-roller chain. Ukucima yinkqubo yokufudumeza izinto zesinyithi ze-roller chain (ezifana neekhonkco, ii-roller, kunye neepini) ukuya kubushushu be-austenitization (ngesiqhelo i-800-900°C, kuxhomekeke kulwakhiwo lwezinto), kugcinwe ubushushu ixesha elithile ukuvumela izinto ukuba ziqine ngokupheleleyo, kwaye emva koko zipholise ngokukhawuleza izinto emanzini, kwi-oyile, okanye kwezinye iindawo zokupholisa. Le nkqubo iguqula isakhiwo sekristale sesinyithi ukusuka kwi-austenite ukuya kwi-martensite, isakhiwo esibonakala ngobunzima obukhulu kodwa sibuthathaka. Njengesiqwenga seglasi, esiqinileyo kodwa siqhekeka lula, izinto ezingaqiniswanga zinokwaphuka ngenxa yempembelelo okanye ukungcangcazela xa zisetyenziswa ngokwenene.
Ukufudumala kubandakanya ukuphinda kufudumale izinto zesinyithi ezicinyiweyo ukuya kubushushu obungaphantsi kwendawo yokutshintsha kwesigaba (ngesiqhelo yi-150-650°C), kugcinwe ubushushu ixesha elithile, kuze kupholiswe kancinci. Le nkqubo inciphisa uxinzelelo lwangaphakathi kwi-martensite kwaye ilungisa isakhiwo sekristale sezinto ngokusebenzisa ukusasazwa kunye nokuchacha kwe-carbide. Ngokufuziselayo, ukufudumala kufana nokuphatha "iglasi" ecinyiweyo ngokufanelekileyo, ukugcina ubunzima obuthile ngelixa kwandisa ukuqina kwayo kunye nokuthintela ukwaphuka okubuthathaka.
2. Impembelelo Yokusebenza: Ubugcisa Bokulinganisela Ubulukhuni, Ukuqina, kunye Nokumelana Nokunxiba
Kwizicelo ze-roller chain, izinto kufuneka zibe nobunzima obuthile bokumelana nokuguguleka kunye nokuqina okwaneleyo kokumelana nempembelelo kunye nokugoba okuphindaphindiweyo. Ukudibanisa ukucima kunye nokushisa kwenzelwe ngokuchanekileyo ukufezekisa olu lungelelwaniso.
Ukucima kunokuphucula kakhulu ubulukhuni kunye nokumelana nokuguguleka kwezinto zeroller chain. Umzekelo, emva kokucima, ubulukhuni bomphezulu weeroller bunokwandiswa nge-30%-50%, bumelane ngempumelelo nokungqubana kunye neempembelelo ze-sprockets kwaye bude ubomi bazo benkonzo. Nangona kunjalo, njengoko bekutshiwo ngaphambili, izinto ezicinyiweyo zibuthathaka ngakumbi kwaye zinokwaphuka okanye zaphuke phantsi kwemithwalo enzima okanye ukungqubana.
Ukufudumala, ukongeza ekucimeni, kulungisa iipropati zezinto ngokulawula ubushushu bokufudumeza kunye nexesha lokubamba. Ukufudumala okuphantsi kobushushu (150-250°C) kunokugcina ubulukhuni obuphezulu ngelixa kunciphisa ukuphuka, okwenza ukuba kufaneke kwiindawo ezifuna ubulukhuni obuphezulu, njengeeroli. Ukufudumala okuphakathi kobushushu (300-450°C) kunika ukuthamba okuphezulu kunye nokuqina, okuhlala kusetyenziswa kwiindawo ezigoba ngokuphindaphindiweyo, njengeepleyiti zetyathanga. Ukufudumala okuphezulu kobushushu (500-650°C) kunciphisa kakhulu ubulukhuni ngelixa kwandisa ukuqina kunye nokuqina, okwenza ukuba kufaneke kwiindawo ezifuna ubulukhuni obuphezulu, njengeepini.
3. Ulandelelwano lweNkqubo: Ulwalamano oluHlangeneyo olungenakuguqulwa
Kwimveliso ye-roller chain, ukucima kunye nokulungisa ngokuqhelekileyo kwenziwa ngolandelelwano "lokucima kuqala, emva koko ukulungelelanisa." Olu landelelwano lumiselwa ziimpawu zenkqubo nganye.
Ukucima kwenziwa ukuze kufunyanwe isakhiwo se-martensitic esiqinileyo, kubekwa isiseko sokulungiswa kokusebenza okulandelayo. Ukuba ukucima kwenziwa ngaphambi kokucima, isakhiwo esenziwe ngokucinezela siya kutshatyalaliswa ngexesha lenkqubo yokucima, singaphumeleli ukusebenza okufunekayo. Ukucima, kwelinye icala, kuphucula isakhiwo emva kokucima, kususa uxinzelelo lwangaphakathi, kwaye kulungisa ubulukhuni kunye nokuqina ukuze kuhlangatyezwane neemfuno zokwenyani zesicelo. Umzekelo, ngexesha lokuveliswa kwepleyiti yetsheyini, kuqala ziyacinywa ukuze kwandiswe ubulukhuni bazo. Emva koko ziyacinywa kubushushu obuphakathi ngokwendlela ekucetywayo ukuyisebenzisa. Oku kuqinisekisa ukuba itsheyini igcina ubulukhuni obuthile ngelixa igcina ubulukhuni obuhle, ivumela ukuba imelane nokugoba nokulula okuphindaphindiweyo ngexesha lokusebenza kwetsheyini.
4. Impembelelo Esebenzayo Kumgangatho We-Roller Chain: Izalathiso Eziphambili Abathengi Abamele Bazihlolisise
Kubathengi, ukuqonda umahluko phakathi kokucima kunye nokushisa kubanceda bahlole umgangatho we-roller chain baze bakhethe iimveliso ezifanelekileyo kwizicelo zabo ezithile.
Isalathisi soBulukhuni: Ukuvavanya ubulukhuni bezinto zeroller chain kunika uvavanyo lokuqala lwenkqubo yokucinywa. Ngokubanzi, ubulukhuni beroller kufuneka bube phakathi kwe-HRC 58-62, obo beetrafti zeroller phakathi kwe-HRC 38-42, kunye nobo bepini phakathi kwe-HRC 45-50 (amaxabiso athile anokwahluka ngokuxhomekeke kwiinkcukacha kunye nokusetyenziswa). Ukuba ubulukhuni alwanelanga, oko kubonisa ukuba ubushushu bokucinywa okanye izinga lokuphola belinganelanga; ukuba ubulukhuni buphezulu kakhulu, kusenokuba kungenxa yokunganyamezelani ngokwaneleyo, okubangela ukuba bube buthathaka kakhulu.
Isalathisi soBulukhuni: Ubulukhuni bunokuvavanywa ngeendlela ezifana novavanyo lokuchaphazela. Itsheyini eqengqelekayo esemgangathweni ophezulu akufuneki iqhekeke okanye iqhekeke xa ithwaxwa yimithwalo ethile yokuchaphazela. Ukuba itsheyini iqhekeka lula ngexesha lokusetyenziswa, kusenokuba kungenxa yobushushu obungafanelekanga, nto leyo ebangela ukuqina kwezinto ezinganeleyo.
Ukumelana nokuguguleka: Ukumelana nokuguguleka kunxulumene nobunzima kunye nolwakhiwo oluncinci lwento. Izinto ezisetyenziswa kwi-roller chain ezicinyiweyo ngokupheleleyo kwaye ziqiniswe ngokufanelekileyo zinesakhiwo esincinci somphezulu oxineneyo, ukumelana nokuguguleka okugqwesileyo, kwaye zinokugcina ukusebenza kakuhle xa zisetyenziswa ixesha elide. Abathengi banokuvavanya ukumelana nokuguguleka ngokuqonda iiparameter zenkqubo yonyango lobushushu yomthengisi kunye nokuphonononga ingxelo yovavanyo lobomi benkonzo yemveliso.
5. Indlela yokukhetha: Ukufanisa iiParamitha zeNkqubo neSicelo
Izicelo ezahlukeneyo zineemfuno ezahlukeneyo zokusebenza kwee-roller chains, ngoko ke iiparameter ezifanelekileyo zenkqubo yokucima kunye nokulungisa kufuneka zikhethwe ngokusekelwe kwiimfuno zokwenyani.
Kwizicelo zothumelo olunzima nolukhawulezayo, ezifana noomatshini bemigodi nezixhobo zokuphakamisa, iiroller chain zifuna ubulukhuni obuphezulu kunye nokumelana nokuguguleka, ngelixa zinobulukhuni obaneleyo bokumelana nemithwalo emikhulu yempembelelo. Kwezi meko, kufuneka kusetyenziswe i-quench yobushushu obuphezulu kunye ne-intermediate-tempering efanelekileyo ukuqinisekisa ukusebenza kakuhle kwezinto. Kwizicelo zothumelo olulula nolukhawulezayo, ezifana noomatshini bokulungisa ukutya kunye nezixhobo zokuhambisa, iimfuno zobulukhuni beeroller chain ziphantsi kakhulu, kodwa ubulukhuni kunye nokugqitywa komphezulu kuphezulu. Ukucima ububushushu obuphantsi kunye nobushushu obuphezulu kunokusetyenziswa ukuphucula ubulukhuni kunye nokuqina kwezinto.
Ukongeza, izinto ezingqongileyo zinokuchaphazela ukukhethwa kwenkqubo. Kwiindawo ezirhabaxa, unyango lomphezulu we-roller chain luyafuneka, kwaye iinkqubo zokucima kunye nokunciphisa umphezulu zinokuchaphazela ukusebenza kakuhle konyango lomphezulu, ngoko ke kufuneka kuqwalaselwe ngokupheleleyo.
