Uhlalutyo lwezoqoqosho loKhetho lweRoller Chain
Kwiinkqubo zothumelo lwemizi-mveliso, iiroller chains, njengenxalenye ephambili edibanisa ukuthembeka kunye nokuguquguquka, zisetyenziswa kakhulu kwiindawo ezahlukeneyo ezifana nokuvelisa oomatshini, izixhobo zezolimo, kunye nokuthuthwa kwezinto.imixokelelwane yeroller, iinkampani zihlala ziwela kumgibe wokukhetha "amaxabiso kuphela"—zikholelwa ukuba okukhona ixabiso lokuqala lokuthenga liphantsi, kokukhona liphantsi, ngelixa zingayinaki iindleko ezifihlakeleyo ezifana nokulahlekelwa lixesha lokungasebenzi, iindleko zokulungisa ezikhulayo, kunye nenkunkuma yamandla enokubangelwa kukukhetha okungafanelekanga. Ukukhetha koqoqosho lokwenyani kugxile ekudluleleni ngaphaya komlinganiselo omnye weendleko kunye nokusebenzisa "iXabiso loMjikelo woBomi (LCC)" njengeyona nto iphambili yokufezekisa iindleko ezifanelekileyo kuyo yonke inkqubo yokuthenga, ukusetyenziswa, kunye nokugcinwa. Eli nqaku liza kuhlalutya eyona nto iphambili yokusebenza kakuhle kwezoqoqosho ekukhetheni i-roller chain ukusuka kumanqanaba amathathu: ingqiqo yokukhetha, izinto eziphambili ezinempembelelo, kunye nemigaqo esebenzayo.
I. Ingcamango Esisiseko Yokukhetha Uqoqosho: Ukubaleka Umgibe "Weendleko Zokuqala"
"Ukusebenza kakuhle kwezoqoqosho" kwee-roller chains akupheleli nje kwixabiso lokuthenga, kodwa kukubalwa okubanzi "kotyalo-mali lokuqala + iindleko zokusebenza + ilahleko ezifihlakeleyo." Iinkampani ezininzi zikhetha ii-supply chains ezixabiso liphantsi ukulawula iindleko zexesha elifutshane, kodwa zijongene nokutshintsha okuphezulu "rhoqo kwiinyanga ezintathu," kunye nokuvalwa kwemigca yemveliso ngenxa yokugcinwa kunye neendleko zabasebenzi ezonyukayo, ekugqibeleni okubangela ukuba iindleko zizonke zidlule kakhulu kwezo zee-supply chains ezisemgangathweni ophezulu.
Umzekelo, xa sithatha isityalo sokulungisa iinxalenye zeemoto: Itsheyini yeroli engeyoyesiqhelo ethengwe kwi-800 yuan inobomi obuqhelekileyo beenyanga ezi-6 kuphela, efuna ukutshintshwa kabini ngonyaka. Ixesha lokungasebenzi lokulungisa ngalinye liziiyure ezi-4. Ngokusekelwe kumgca wemveliso ixabiso lemveliso ngeyure le-5000 yuan, ilahleko yonyaka efihliweyo ifikelela kwi-40,000 yuan (kubandakanya umsebenzi wokulungisa kunye nelahleko yemveliso yexesha lokungasebenzi), kunye notyalo-mali olupheleleyo lonyaka lwe-800×2+40000=41600 yuan. Ngokwahlukileyo koko, ukukhetha itsheyini yeroli esemgangathweni ophezulu ehambelana nemigangatho ye-DIN, enexabiso lokuqala lokuthenga le-1500 yuan, ubomi beenyanga ezingama-24, efuna ukugcinwa kube kanye ngonyaka kunye neeyure ezi-2 zokungasebenzi, kuphumela kutyalo-mali olupheleleyo lonyaka lwe-1500÷2+20000=20750 yuan. Ukunciphisa iindleko ngokubanzi kwiminyaka emibini kungaphezulu kwe-50%.
Ngoko ke, ingxaki ephambili ekukhetheni ayikokuba “ibiza kakhulu xa ithelekiswa nexabiso eliphantsi,” kodwa kukulingana phakathi “kotyalo-mali lwexesha elifutshane” kunye “nexabiso lexesha elide.” Ixabiso lilonke loMjikelo woBomi (LCC) = Ixabiso lokuThenga lokuqala + Ixabiso loFakelo + Ixabiso loLondolozo + Ilahleko yexesha lokungasebenzi + Ixabiso lamandla + Ixabiso lokulahla. Kuphela ngokukhetha uthotho olusekelwe kule fomula apho ukusebenza kakuhle koqoqosho kungenziwa khona.
II. Izinto Ezine Eziphambili Ezichaphazela Ukusebenza Kakuhle Kwezoqoqosho Kokukhetha Iitsheyini
1. Ukuhambelana ngokuchanekileyo koMthwalo kunye namandla: Ukuphepha "uyilo olugqithisileyo" kunye "noyilo olungaphantsi" Amandla etsheyini eqengqelekayo kufuneka ahambelane ngokuchanekileyo nomthwalo wokwenyani; esi sisiseko sokusebenza kakuhle kwezoqoqosho. Ukusukela ngokungaboniyo "amandla aphezulu" nokukhetha imodeli yetsheyini edlula kakhulu iimfuno zokwenyani (umz., ukukhetha itsheyini enomthwalo olinganisiweyo we-100kN kumthwalo wokwenyani we-50kN) kuya kunyusa iindleko zokuthenga ngaphezulu kwe-30%. Kwangaxeshanye, ubunzima betsheyini obunyukileyo buya kwandisa ukumelana nokudluliselwa, okukhokelela ekonyukeni kwe-8%-12% ekusetyenzisweni kwamandla ngonyaka. Ngokwahlukileyo koko, ukukhetha itsheyini engomelelanga kuya kubangela ukwaphuka kokudinwa, ukuwohloka kwekhonkco letsheyini ngokukhawuleza, kunye nokulahleka kwexabiso lemveliso kwiyure nganye yexesha lokungasebenzi kunokulingana nexabiso lokuthenga letsheyini ngokwayo izihlandlo ezininzi.
Xa ukhetha imodeli, kuyimfuneko ukubala ukhuseleko olusekelwe kuhlu lwamandla emigangatho yamazwe ngamazwe (njenge-DIN, i-ASIN) kunye neeparamitha ezifana nomthwalo olinganisiweyo, umthwalo wempembelelo, kunye nomthwalo we-peak okhawulezileyo phantsi kweemeko zokusebenza zangempela (ukhuseleko oluyi-≥1.5 luyacetyiswa kwiimeko zoshishino kunye no-≥2.0 kwiimeko ezinzima). Umzekelo, i-12A series roller chain (pitch 19.05mm) ifanelekile kwi-medium-load transmission, ngelixa i-16A series (pitch 25.4mm) ifanelekile kwiimeko ezinzima. Ukudibanisa ngokuchanekileyo kunokulawula iindleko zokuqala kwaye kuphephe ilahleko ezifihlakeleyo ezibangelwa kukungabikho kwamandla aneleyo.
2. Uhlengahlengiso lweMeko yokuSebenza: Izinto eziHleliweyo kunye noKhetho lweSakhiwo Iimeko zokusebenza ezahlukeneyo zibeka iimfuno ezahlukeneyo kakhulu kwizinto kunye nolwakhiwo lwee-roller chains. Ukungahoyi iimpawu zeemeko zokusebenza ngexesha lokukhetha kuya kunciphisa ngokuthe ngqo ubomi be-chain kwaye kwandise iindleko zokugcinwa: Kwiimeko zokusebenza eziqhelekileyo (ubushushu obuqhelekileyo, owomileyo, umthwalo ophantsi ukuya kophakathi): ii-roller ze-carbon steel zanele, zibonelela ngomlinganiselo ongcono weendleko-ukusebenza, iindleko zokuqala zokuthenga eziphantsi, ulondolozo olulula, kunye nobomi benkonzo beminyaka eli-1-2; Kwiimeko zokusebenza ezirhabaxa/ezinomswakama (iikhemikhali, ukucubungula ukutya, izixhobo zangaphandle): ii-roller ze-stainless steel okanye ii-chains ezine-surface anti-corrosion treatment (ezifakwe i-galvanized, ezifakwe i-chrome-plated) ziyafuneka. Ixabiso lokuqala lokuthenga lale ion liphezulu ngama-20%-40% kunele-carbon steel chains, kodwa ubomi bazo benkonzo bunokwandiswa ngamaxesha ama-3-5, kuthintelwe ukulahleka kwexesha lokungasebenzi kunye neendleko zomsebenzi ezibangelwa kukutshintshwa rhoqo.
Kwiimeko zobushushu obuphezulu/zothuli (isinyithi, izixhobo zokwakha, ukumbiwa kwemigodi): kufuneka kukhethwe imixokelelwane yerola eyenziwe ngee-alloys ezimelana nobushushu obuphezulu okanye enezakhiwo ezivaliweyo. Uyilo oluvaliweyo lunciphisa uthuli olungena kwizithuba zekhonkco, lunciphisa izinga lokuguguleka, lwandise umjikelo wolondolozo ukusuka kwiinyanga ezi-3 ukuya kwiinyanga ezili-12, kwaye lunciphisa iindleko zolondolozo zonyaka ngaphezulu kwama-60%.
Kwiimeko zokuhambisa umgama omde (ukuhlelwa kwezinto, oomatshini bezolimo): Iitsheyini zokuhambisa eziphindwe kabini zikhetho olungabizi kakhulu. Zinepitch enkulu, ubunzima obulula, ukumelana nokudluliselwa okuphantsi, ukusetyenziswa kwamandla okuphantsi nge-15% kuneetsheyini zeroller eziqhelekileyo, ukusasazwa komthwalo okulinganayo, kunye nobomi obude ngama-20%.
3. Uyilo lweSilinganiselo seGear kunye nokusebenza kakuhle koThumelo: Iindleko zamandla ezifihlakeleyo
Ukuhambelana komlinganiselo wegiya phakathi kwetyathanga lerola kunye ne-sprocket kuchaphazela ngokuthe ngqo ukusebenza kakuhle kothumelo, kwaye ukulahleka kokusebenza kakuhle ekugqibeleni kuthetha iindleko zamandla. Uyilo olungafanelekanga lomlinganiselo wegiya (njengokungalingani phakathi kwe-chain pitch kunye nenani lamazinyo e-sprocket) lunokukhokelela ekungahambelani kakuhle kwe-meshing, ukwanda kokungqubana okutyibilikayo, kunye nokuncipha kwe-5%-10% ekusebenzeni kakuhle kothumelo. Kwisixhobo se-15kW esisebenza iiyure ezingama-8000 ngonyaka, ukwehla ngakunye kwe-1% ekusebenzeni kakuhle kubangela ukusetyenziswa kombane okongezelelweyo kwe-1200kWh ngonyaka. Ngexabiso lombane wemizi-mveliso eliyi-0.8 yuan/kWh, oku kuthetha ukuba yi-960 yuan eyongezelelweyo ngonyaka.
Xa ukhetha i-sprocket, kufuneka kulandelwe "umgaqo woyilo lwe-gear ratio": inani lamazinyo e-sprocket kufuneka libe phakathi kwamazinyo ali-17 nama-60 ukuze kuthintelwe ukuguguleka kakhulu kwe-chain ngenxa yamazinyo ambalwa kakhulu okanye ukwanda kokumelana nokudluliselwa ngenxa yamazinyo amaninzi kakhulu. Kwangaxeshanye, ukukhetha i-roller chain echanekileyo kakhulu kunye ne-small pitch error (njenge-A-series short-pitch precision double-link roller chain) kunokuphucula ukuchaneka kwe-meshing, kuzinzise ukusebenza kakuhle kokudluliselwa ngaphezulu kwe-95%, kwaye kunciphise kakhulu iindleko zamandla ekuhambeni kwexesha.
4. Ukulula koLondolozo: "Inzuzo efihlakeleyo" yokunciphisa ixesha lokungasebenzi Ixesha lokungasebenzi lokugcinwa "liyingxaki enkulu" kwimveliso yemizi-mveliso, kwaye uyilo lwesakhiwo see-roller chain luchaphazela ngokuthe ngqo ukusebenza kakuhle kolondolozo. Umzekelo, ii-roller chain ezinee-offset links zivumela ukulungiswa ngokukhawuleza kobude be-chain, ukunciphisa ixesha lokuqhaqha kunye nokuhlanganiswa, kunye nokunciphisa ixesha lokugcinwa elinye ukusuka kwiiyure ezi-2 ukuya kwimizuzu engama-30. Ngaphezu koko, uyilo lwee-modular chain link lususa isidingo sokutshintshwa ngokupheleleyo kwe-chain; kuphela ii-link ezigugileyo ekufuneka zitshintshwe, okunciphisa iindleko zokugcinwa nge-70%.
Ukongeza, kufuneka kuqwalaselwe ukuguquguquka kweendawo zokunxiba: ukukhetha iiroller chain ezihambelana nemigangatho yamazwe ngamazwe kuvumela ukuthengwa lula kweendawo zokunxiba ezifana neelinki, iiroller, kunye neepini kwihlabathi liphela, kuthintelwe ixesha elide lokungasebenzi ngenxa yokunqongophala kweendawo. Iinkonzo zokwenza ngokwezifiso ze-OEM/ODM ezinikezelwa zezinye iimpawu zinokuphucula ngakumbi ulwakhiwo lweroller ngokweemfuno zezixhobo, nto leyo ephucula ngakumbi ukugcinwa lula.
III. Iingcamango Ezintathu Eziqhelekileyo Ezingalunganga Ekukhetheni Iitsheyini Zokusebenza Kakuhle Kwezoqoqosho, Ukuwela Kumgibe Wee-90% Zamashishini
1. Ukusukela Amaxabiso Aphantsi Ngokungaboniyo: Ukungayinaki Imigangatho Nokuthobela
