Esigabeni esikhulu semboni yanamuhla, kukhona ingxenye ebonakala ilula kodwa ebalulekile esekela buthule ukusebenza kwemishini eminingi, okungukuthi, uchungechunge lwama-roller. Lesi sihloko sizokuyisa ekujuleni kwezwe le-amaketanga okugoqa, kusukela esimisweni sayo sokusebenza kuya endimeni yayo ebalulekile embonini yanamuhla. Ake sihlole imfihlakalo yale nhliziyo yezimboni ndawonye.
Umsuka kanye nokuvela kwamaketanga okugoqa
Imvelaphi yamaketanga okugoqa ingalandelelwa emuva ku-180 BC, lapho iShayina yasungula idivayisi ebizwa ngokuthi “i-chain drive” yokuphakamisa amasondo amanzi. Kodwa-ke, iketanga lokugoqa langempela lasungulwa nguCharles F. Kratzer ngasekupheleni kwekhulu le-19. Wathuthukisa iketanga eliyisicaba lendabuko futhi wanezela ama-roller, okwathuthukisa kakhulu ukusebenza kahle kanye nomthamo womthwalo weketanga lokugoqa.
Ngokuthuthuka kwenguquko yezimboni, uhla lokusetshenziswa kwamaketanga okugoqa luye lwaqhubeka nokukhula. Kusukela kumabhayisikili kuya ezimotweni, kusukela emishinini yezindwangu kuya emigqeni yokukhiqiza yezimboni yesimanje, amaketanga okugoqa asekhona yonke indawo. Umklamo wawo uphinde ulungiselelwe njalo ukuze uvumelane nesivinini esiphezulu kanye nemithwalo emikhulu.
Isakhiwo kanye nomgomo wokusebenza we-roller chain
Iketanga lama-roller liqukethe uchungechunge lwezixhumanisi ezixhumene, ngalinye eliqukethe amapuleti amabili eketanga kanye ne-roller eyodwa. Amapuleti eketanga avame ukwenziwa ngensimbi, kuyilapho ama-roller enziwe ngensimbi eqinile ukunciphisa ukungqubuzana nokuthuthukisa ukumelana nokuguguleka. Izixhumanisi zamaketanga zixhunywe ngamaphini nemikhono ukuze kwakheke i-whole eguquguqukayo neqinile.
Isimiso sokusebenza se-roller chain sisekelwe ekungqubuzaneni nasekuhlanganiseni. Lapho umthombo wamandla (njengemoto) ushayela i-sprocket, amazinyo e-sprocket mesh ngamapuleti e-chain angaphakathi e-roller chain, esunduza izixhumanisi ze-chain endleleni enqunyiwe. Ama-roller ajikeleza phakathi kwezixhumanisi ze-chain nama-sprocket, enciphisa ukungqubuzana futhi enze ukudluliselwa kwamandla kube ngcono.
Izinzuzo kanye nokusetshenziswa kwamaketanga okugoqa
Isizathu sokuthi amaketanga e-roller asetshenziswa kabanzi embonini ikakhulukazi ngenxa yezinzuzo ezilandelayo:
Ukusebenza kahle okuphezulu: Ukungqubuzana okugoqayo kwamaketanga okugoqa kuncane kakhulu kunokungqubuzana okushelelayo, okusho ukuthi kungadlulisela amandla amakhulu ngokusetshenziswa kwamandla okuphansi.
Umthamo womthwalo ophezulu: Ngenxa yokuba khona kwama-roller, amaketanga ama-roller angamelana nemithwalo emikhulu futhi afanele imishini esindayo.
Ukuphila isikhathi eside: Amaketanga okugoqa asezingeni eliphezulu angasetshenziswa iminyaka eminingi ngokunakekelwa okufanele, okunciphisa izindleko zokufaka esikhundleni.
Ukuthembeka: Umklamo wamaketanga okugoqa ulula futhi uthembekile, futhi angasebenza kahle ngisho nasezindaweni zokusebenza ezinzima.
Ukusetshenziswa kwamaketanga okugoqa kubanzi kakhulu, kufaka phakathi kodwa kungagcini lapho:
Imboni yezimoto: Enjinini yemoto, kusetshenziswa amaketanga okugoqa ukushayela i-camshaft ukuqinisekisa ukuvulwa nokuvalwa okunembile kwamavalvu.
Amabhayisikili nezithuthuthu: Amaketanga okugoqa ayingqikithi yesistimu yokudlulisa amabhayisikili nezithuthuthu, edlulisela amandla amaphedali emasondweni.
Imishini yezimboni: Ezimbonini ezifana nezindwangu, ukupakisha, kanye nokunyathelisa, amaketanga okugoqa asetshenziswa ukushayela izingxenye ezahlukene zemishini ukuze kufezwe ukunyakaza okuqondile okuhambisanayo.
Imishini yezolimo: Emishini yezolimo efana nemishini yokuvuna kanye namatrakta, amaketanga okugoqa asetshenziswa ukudlulisa amandla nokuthuthukisa ukusebenza kahle komsebenzi.
Ukunakekelwa nokuxazulula izinkinga zamaketanga ajikelezayo
Nakuba amaketanga okugoqa aziwa ngokuqina kwawo, ukulungiswa okufanele kusabalulekile. Nazi ezinye izinyathelo zokulungisa eziyisisekelo:
Ukuhlolwa okuvamile: Hlola ukuthi izixhumanisi zeketanga zibonisa yini izimpawu zokuguguleka, ukwelula, noma umonakalo.
Ukuhlanza: Hlanza iketanga le-roller njalo ukuze ususe uthuli namafutha ukuze unciphise ukuguguleka.
Ukugcoba: Gcoba ngamafutha afanele ukuze unciphise ukungqubuzana futhi uvimbele ukugqwala.
Ukulungiswa kokucindezeleka: Gcina ukucindezeleka okufanele. Ukuxega kakhulu noma ukuqina kakhulu kuzothinta impilo nokusebenza kahle kweketanga.
Uma iketanga le-roller lihluleka, izinkinga ezivamile zifaka:
Ukuguga kwezixhumanisi zeketanga: Ukuguga ngokweqile kwezixhumanisi zeketanga kungabangela ukuthi iketanga liphuke.
Ukwelula uchungechunge: Ukusetshenziswa kwesikhathi eside kuzolula kancane kancane uchungechunge futhi kuthinte i-meshing.
Umonakalo we-roller: Umonakalo we-roller uzokwenza ukuthi ukudluliselwa kwamandla kungabi bushelelezi.
Kulezi zinkinga, ukushintshwa nokulungiswa ngesikhathi kuyadingeka.
Izitayela zentuthuko yesikhathi esizayo zamaketanga okugoqa
Ngokuthuthuka kobuchwepheshe, amaketanga okugoqa nawo athuthuka njalo. Nazi ezinye zezindlela zokuthuthukiswa kwesikhathi esizayo:
Ukusungula izinto ezintsha: Ukusetshenziswa kwezinto ezintsha, njengepulasitiki enamandla amakhulu nezinto ezihlanganisiwe, kungenza amaketanga okugoqa abe lula futhi aqine kakhudlwana.
Ubuhlakani: Amaketanga e-roller anezinzwa ezihlanganisiwe angaqapha isimo sawo ngesikhathi sangempela futhi abikezele izidingo zokulungisa.
Umklamo onobungani nemvelo: Izinto ezingasetshenziswa kabusha kanye nomklamo wokusetshenziswa kwamandla aphansi kuzokwenza amaketanga okugoqa abe nobungani nemvelo.
Ukwenza Ngokwezifiso: Ngokuthuthuka kobuchwepheshe bokuphrinta be-3D, amaketanga e-roller enziwe ngokwezifiso azokwazi ukuhlangabezana nezidingo zezinhlelo zokusebenza ezithile.
Isiphetho
I-roller chain, inhliziyo yemboni kanye nomfutho wemishini, isekela ukusebenza kwemboni yesimanje ngomklamo wayo olula nonamandla. Ngokuthuthuka okuqhubekayo kobuchwepheshe, i-roller chain izoqhubeka nokudlala indima engenakuphikwa emkhakheni wezimboni. Ukuqonda i-roller chain ukuqonda itshe eliyisisekelo lemboni nokuqonda umongo wemishini.
