I-roller chain wuhlobo lweketango elisetshenziselwa ukudlulisa amandla emishini.Iwuhlobo lwe-chain drive futhi isetshenziswa kakhulu emishinini yasendlini, yezimboni neyezolimo, okubandakanya abathumeli, abaklami, imishini yokuphrinta, izimoto, izithuthuthu namabhayisikili.Ixhunywe ndawonye uchungechunge lwama-cylindrical roller amafushane futhi ishayelwa igiya elibizwa ngokuthi i-sprocket, okuwumshini wokudlulisa amandla olula, othembekile futhi osebenza kahle.
1.Isingeniso se-Roller Chain:
Amaketango e-roller ngokuvamile abhekisela kumaketanga ama-roller anembayo wokudlulisa iphimbo elifushane, asetshenziswa kakhulu futhi akhiphayo amakhulu kakhulu.Amaketanga e-roller ahlukaniswe abe umugqa owodwa kanye nemigqa eminingi, afanele ukudluliswa kwamandla amancane.Ipharamitha eyisisekelo yeketango le-roller iyi-chain link p, elingana nenombolo yeketanga leketango eliphindwe ngo-25.4/16 (mm).Kunezinhlobo ezimbili zezijobelelo enombolweni yeketango, u-A no-B, okubonisa uchungechunge olubili, futhi uchungechunge olubili luyaphelelisana.
2.ukwakheka kwe-roller chain:
Iketango le-roller lakhiwe i-inner chain plate 1, i-outer chain plate 2, iphinikhodi engu-3, umkhono 4 kanye ne-roller 5. I-internal chain plate kanye nomkhono, i-outer chain plate kanye nephinikhodi konke kuyalingana. ;ama-roller kanye nomkhono, kanye nomkhono kanye nephinikhodi konke okuhambisanayo.Uma usebenza, izixhumanisi zamaketanga angaphakathi nangaphandle zingaphambukisa isihlobo komunye nomunye, umkhono ungajikeleza ngokukhululekile eduze kwe-pin shaft, futhi i-roller isethwe emkhonweni ukuze kuncishiswe ukuguga phakathi kweketango ne-sprocket.Ukuze unciphise isisindo futhi wenze amandla esigaba ngasinye alingane, amapuleti eketango angaphakathi nangaphandle ngokuvamile enziwa abe umumo othi “8”.[2] Ingxenye ngayinye yeketango yenziwe nge-carbon steel noma i-alloy steel.Ngokuvamile ngokusebenzisa ukwelashwa ukushisa ukuze kuzuzwe amandla athile nobulukhuni.
3.I-Roller Chain Pitch:
Ibanga eliphakathi nendawo ukuya phakathi nendawo phakathi kwamaphinikhodi amabili asondelene ochungechungeni libizwa ngokuthi i-chain pitch, echazwa ngo-p, okuyipharamitha ebaluleke kakhulu yeketango.Lapho iphimbo likhula, ubukhulu bengxenye ngayinye yeketango buyanda ngokufanele, futhi amandla angadluliselwa nawo anda ngokufanele.[2] I-pitch yeketango p ilingana nenombolo yeketango leketango le-roller eliphindwe ngo-25.4/16 (mm).Isibonelo, inombolo yeketango 12, i-roller chain pitch p=12×25.4/16=19.05mm.
4.Isakhiwo se-roller chain:
Amaketanga e-roller ayatholakala ngamaketanga emigqa eyodwa kanye nemigqa eminingi.Uma kudingekile ukuthwala umthwalo omkhulu futhi udlulise amandla amakhulu, imigqa eminingi yamaketanga ingasetshenziswa, njengoba kuboniswe kuMfanekiso 2. Amaketanga anemigqa eminingi alingana namaketanga amaningana avamile omugqa owodwa axhunywe omunye nomunye ngamaphini amade.Akufanele kube kuningi, okuvame ukusetshenziswa amaketanga anemigqa emibili kanye namaketanga emigqa emithathu.
5.Ifomu lokuhlanganisa i-roller:
Ubude beketango bumelwe inani lezixhumanisi zamaketango.Ngokuvamile, kusetshenziswa isixhumanisi seketango elinenombolo elinganayo.Ngale ndlela, izikhonkwane ezihlukanisiwe noma iziqeshana zasentwasahlobo zingasetshenziswa emalungeni eketango.Uma i-curved chain plate ingaphansi kwengcindezi, isikhathi sokugoba esengeziwe sizokwenziwa, futhi ngokuvamile kufanele kugwenywe ngangokunokwenzeka.
6.I-Roller chain standard:
I-GB/T1243-1997 ibeka ukuthi amaketanga e-roller ahlukaniswe abe uchungechunge lwe-A no-B, phakathi kwalo uchungechunge lwe-A lusetshenziselwa isivinini esikhulu, umthwalo osindayo kanye nokudluliselwa okubalulekile, okuvame ukusetshenziswa kakhulu.Inombolo yeketango ephindwe ngo-25.4/16mm inani le-pitch.Uchungechunge B lusetshenziselwa ukudluliselwa okuvamile.Ukumakwa kwe-roller chain yilokhu: iketango inombolo eyodwa umugqa inombolo eyodwa iketango inombolo inombolo eyodwa inombolo ejwayelekile.Isibonelo: i-10A-1-86-GB/T1243-1997 isho ukuthi: Iketango le-roller eliwuchungechunge, iphimbo lingu-15.875mm, umugqa owodwa, inani lezixhumanisi ngu-86, izinga lokukhiqiza i-GB/T1243-1997
7.Ukusetshenziswa kwe-roller chain:
I-Chain drive isetshenziswa kabanzi emishinini ehlukahlukene ezimbonini ezahlukahlukene ezifana nezolimo, izimayini, i-metallurgy, imboni ye-petrochemical kanye nokuphakamisa ezokuthutha.Amandla angadluliswa ngamaketango angafinyelela ku-3600kW, futhi ngokuvamile asetshenziselwa amandla angaphansi kuka-100kW;isivinini seketango singafinyelela ku-30 ~ 40m/s, futhi isivinini seketango esivame ukusetshenziswa singaphansi kuka-15m/s;~ 2.5 kufanelekile.
8.Izici ze-roller chain drive:
inzuzo:
Uma iqhathaniswa ne-belt drive, ayinakho ukushelela okunwebekayo, ingagcina isilinganiso esinembile sokudlulisa isilinganiso, futhi inekhono eliphezulu lokudlulisela;iketango alidingi amandla amakhulu okucindezela, ngakho-ke umthwalo ku-shaft nokuthwala kuncane;ngeke ishelele, ukudluliswa kunokwethenjelwa, kanye nokulayisha ngokweqile Ikhono elinamandla, lingasebenza kahle ngaphansi kwejubane eliphansi nomthwalo osindayo.
ukushiyeka:
Kokubili ijubane leketango elisheshayo kanye nesilinganiso sokudlulisa ngokushesha siyashintsha, ukuzinza kokudlulisela akulungile, futhi kukhona ukushaqeka nomsindo phakathi nokusebenza.Ayifanele izikhathi zesivinini esikhulu, futhi ayifanele izinguquko ezivamile lapho ujikeleza khona.
9.inqubo yokusungulwa:
Ngokocwaningo, ukusetshenziswa kwamaketanga eChina kunomlando weminyaka engaphezu kuka-3,000.E-China yasendulo, amaloli okulahla kanye namasondo amanzi asetshenziselwa ukuphakamisa amanzi ukusuka phansi ukuya phezulu kufana namaketanga okuthutha anamuhla.Ku-“Xinyixiangfayao” ebhalwe ngu-Su Song ku-Northern Song Dynasty yase-China, kuqoshwe ukuthi okushayela i-armillary sphere kufana nensimbi yokudlulisa iketango eyenziwe ngensimbi yesimanje.Kuyabonakala ukuthi i-China ingelinye lamazwe okuqala ekusetshenzisweni kwe-chain.Kodwa-ke, isakhiwo esiyisisekelo seketango lesimanje saqala ukusungulwa futhi sahlongozwa nguLeonardo da Vinci (1452-1519), usosayensi omkhulu kanye nomdwebi we-European Renaissance.Kusukela ngaleso sikhathi, ngo-1832, uGalle eFrance wasungula iketango lephini, futhi ngo-1864, iketango elingenamikhono lama-Slaite eBrithani.Kodwa kwakungu-Swiss Hans Reynolds owafinyelela ezingeni lomklamo wesakhiwo seketanga lesimanje.Ngo-1880, waphelelisa ukushiyeka kwesakhiwo seketango langaphambilini, waklama iketango laba yisethi ethandwayo yamaketanga ama-roller, futhi wathola i-roller chain e-UK.i-chain invention patent.
