Ngivame ukuzwa abangani bebuza, uyini umehluko phakathi kwamaketanga ophawu lwamafutha esithuthuthu namaketanga avamile?
Umehluko omkhulu phakathi kwamaketanga avamile esithuthuthu kanye namaketanga avaliwe ngowoyela ukuthi ngabe kukhona yini indandatho yokuvala phakathi kwezingcezu zeketanga zangaphakathi nezangaphandle. Bheka kuqala amaketanga avamile esithuthuthu.
Amaketanga angaphakathi nangaphandle amaketanga avamile, iketanga lakhiwe ngamajoyinti angaphezu kwe-100 amaketanga angaphakathi nangaphandle axhunywe ngokushintshana, akukho phawu lwerabha phakathi kwalawa amabili, futhi amaketanga angaphakathi nangaphandle asondelene kakhulu.
Kumaketanga avamile, ngenxa yokuchayeka emoyeni, uthuli namanzi anodaka ngesikhathi sokugibela kuzongena phakathi kwesikhafu nama-roller eketanga. Ngemva kokuba lezi zinto zangaphandle zingene, zizogqoka igebe phakathi kwesikhafu nama-roller njengephepha lokusantisa elicolekile. Endaweni yokuxhumana, igebe phakathi kwesikhafu ne-roller lizokhula ngokuhamba kwesikhathi, futhi ngisho nasendaweni ekahle engenalo uthuli, ukugqokwa phakathi kwesikhafu ne-roller akunakugwenywa.
Nakuba ukuguguleka nokuqhekeka phakathi kwezixhumanisi zeketanga ngalinye kungabonakali emehlweni enyama, uchungechunge lwesithuthuthu luvame ukwakhiwa ngamakhulu ezixhumanisi zeketanga. Uma zibekwe ngaphezulu, kuzoba sobala. Umuzwa oqondakala kakhulu ukuthi uchungechunge lunwetshiwe, ngokuyisisekelo izintambo ezijwayelekile kufanele ziqiniswe kanye cishe ngebanga elingu-1000KM, ngaphandle kwalokho izintambo ezinde kakhulu zizothinta kakhulu ukuphepha kokushayela.
Bheka futhi iketanga lokuvala uwoyela.
Kukhona indandatho yerabha yokuvala phakathi kwamapuleti eketanga angaphakathi nangaphandle, efakwa amafutha, angavimbela uthuli lwangaphandle ukuthi lungene esikhaleni esiphakathi kwama-roller nama-pin, futhi avimbele amafutha angaphakathi ukuthi angaphonswa ngaphandle, futhi anganikeza ukuthambisa okuqhubekayo.
Ngakho-ke, ibanga elide lochungechunge lwezisimbozo zikawoyela libambezeleka kakhulu. Iketanga lezisimbozo likawoyela elithembekile alidingi ukuqinisa uchungechunge ngaphakathi kwamakhilomitha angu-3000, futhi impilo yesevisi iyonke inde kuneyezisimbozo ezivamile, ngokuvamile kungabi ngaphansi kwamakhilomitha angu-30,000 kuya kwangu-50,000.
Kodwa-ke, yize uchungechunge lwezisimbiso zikawoyela luhle, alunazo izinkinga. Okokuqala yintengo. Uchungechunge lwezisimbiso zikawoyela lomkhiqizo ofanayo luvame ukubiza kakhulu ngokuphindwe kane kuya kahlanu kunechungechunge olujwayelekile, noma ngisho nangaphezulu. Isibonelo, intengo yochungechunge lwezisimbiso zikawoyela lwe-DID oludumile ingafinyelela ngaphezu kwe-yuan eyi-1,000, kuyilapho uchungechunge olujwayelekile lwasekhaya lungaphansi kwe-yuan eyi-100, kanti uhlobo olungcono luyi-yuan eyikhulu kuphela.
Khona-ke ukumelana kokusebenza kochungechunge lwezisimbozo zikawoyela kukhulu kakhulu. Ngokwemibono yabantu abavamile, "lufile". Ngokuvamile alufanele ukusetshenziswa kumamodeli amancane okufuduka. Yilawo kuphela amabhayisikili anokufuduka okuphakathi nokukhulu azosebenzisa lolu hlobo lwechungechunge lwezisimbozo zikawoyela.
Okokugcina, uchungechunge lwe-oil seal aluyona iketanga elingenakulungiswa. Naka leli phuzu. Lidinga futhi ukuhlanzwa nokugcinwa. Ungasebenzisi amafutha ahlukahlukene noma izixazululo ezinenani eliphezulu kakhulu noma eliphansi kakhulu le-pH ukuhlanza uchungechunge lwe-oil seal, okungabangela ukuthi indandatho yokuvala iguge futhi ilahlekelwe umphumela wayo wokuvala. Ngokuvamile, ungasebenzisa amanzi angathathi hlangothi anensipho ekuhlanzeni, futhi ukwengeza ibhulashi lamazinyo kungaxazulula inkinga. Noma i-wax ekhethekile yeketanga ingasetshenziswa.
Ngokuqondene nokuhlanza amaketanga avamile, ungasebenzisa uphethiloli ngokuvamile, ngoba unomthelela omuhle wokuhlanza futhi kulula ukuwushintsha. Ngemva kokuhlanza, sebenzisa indwangu ehlanzekile ukuze usule amabala kawoyela bese uwomisa, bese usebenzisa ibhulashi ukuhlanza uwoyela. Vele usule amabala kawoyela.
Ukuqina kweketanga elijwayelekile kuvame ukugcinwa phakathi kuka-1.5CM no-3CM, okuyinto evamile. Lolu lwazi lubhekisela ebangeni lokujika kweketanga phakathi kwama-sprocket angaphambili nangemuva esithuthuthu.
Ukudlula leli nani kuzobangela ukuguguleka kweketanga nama-sprocket ngaphambi kwesikhathi, ama-hub bearings ngeke asebenze kahle, futhi injini izothwala imithwalo engadingekile. Uma iphakeme kunale datha, ngeke isebenze. Ngesivinini esikhulu, iketanga lizojika liye phezulu naphansi kakhulu, futhi lize libangele ukuhlukana, okuzothinta ukuphepha kokushayela.
