Umsebenzi wesondo elicindezelayo kanye nesondo elingasebenzi kahle lejeneretha
Kuhlelo lokushayela oluhambisana nenjini, i-tensioner pulley kanye ne-idler pulley kuyizingxenye ezimbili ezibalulekile ezinemisebenzi ehlukene. Zihlangene, ziqinisekisa ukusebenza okuzinzile nokuphumelelayo kwebhande.
Umsebenzi we-pulley ye-tensioner
Umsebenzi oyinhloko we-tensioner pulley ukulungisa ngokuzenzakalelayo ukucindezeleka kwebhande, ukuqinisekisa ukuthi ibhande lihlala lisesimweni esihle kakhulu sokusebenza. Isebenzisa iziphethu zangaphakathi noma izindlela ze-hydraulic ukuze ibuyisele ngokuzenzakalelayo ukucindezeleka ngokusekelwe ekunwetshweni noma ekugugeni kwebhande, ngaleyo ndlela:
Ukuvimbela ibhande ukuthi lingasheleli noma lingasheleli amazinyo ngenxa yokuxega kakhulu;
Ukugwema ibhande ekusheshiseni ukuguguleka noma ukwandisa umthwalo wenjini ngenxa yokuba liqinile kakhulu;
Ukunciphisa ukudlidliza nomsindo enqubweni yokudlulisa kanye nokuthuthukisa ukuzinza kohlelo.
Ngenxa yokuguga kwezinto ezingaphakathi ezimanzisa amanzi kanye neziphethu, isikhathi sokuphila se-tensioner pulley sivame ukufana nesebhande. Kunconywa ukuthi ufake ibhande esikhundleni salo ukuze ugweme ukwehluleka okulandelayo.
Umsebenzi we-pulley ye-idler
Umsebenzi oyinhloko we-pulley ye-idler ukushintsha indlela yokudlulisela yebhande, kunokudlulisa amandla noma ukulungisa ukucindezeleka. Imisebenzi yayo ethile ihlanganisa:
Ukushintsha indlela yebhande: ukuvumela ibhande ukuthi lidlule izingxenye zenjini eziyinkimbinkimbi (njengemishini yokupholisa umoya, amaphampu amanzi, amajeneretha, njll.);
Ukwandisa i-engeli yokugoqa: ukwandisa indawo yokuxhumana phakathi kwebhande kanye ne-pulley, ukuthuthukisa ukusebenza kahle kokudlulisa, kanye nokunciphisa ingozi yokushelela;
Ukunciphisa ukudlidliza kwebhande: ukuhlinzeka ngokusekelwa okuphakathi ekudlulisweni kwebanga elide, okwenza ibhande lisebenze kahle kakhulu;
Ayishintshi isilinganiso sokudlulisa: i-pulley engasebenzi ishintsha indlela kuphela, ngaphandle kokuthinta isilinganiso sokudlulisa amandla.
I-pulley ye-idler ivame ukufakwa phakathi kwama-pulley amabili ashayelayo noma aqhutshwayo. Lapho ama-bearings e-pulley ye-idler eguga, kungase kube nemisindo noma ukudlidliza okungavamile, okudinga ukushintshwa ngesikhathi.
Ukulimala kwe-pulley ye-generator tensioner (ngezinye izikhathi ebizwa nangokuthi i-pulley ye-idler) kungaba nemiphumela eminingi emibi ekusebenzeni okuvamile kwemoto, okuthinta kakhulu uhlelo lwesikhathi senjini, uhlelo lokushaja, kanye nohlelo lokupholisa.
Imiphumela eyinhloko
Okubangela ukuphazamiseka kwesikhathi senjini: I-pulley ye-tensioner inesibopho sokugcina ukuqina okufanele kwebhande. Uma seliwonakele, ibhande lizoxega, lishelele, noma liphambuke, liphazamise ngqo ukusebenza okunembile kwesistimu yesikhathi senjini, okuholela ekugxumeni kwamazinyo esikhathi. Lokhu kuzobangela ukuphazamiseka okukhulu kwesikhathi, okuholela ekunyakazeni kwenjini, ubunzima bokusha, ngisho nokungakwazi kwemoto ukuqala.
Ingozi enkulu yokulimala kwenjini: Uma i-pulley ye-tensioner yebhande lesikhathi yonakele, isimo siba sibi kakhulu. Ukucindezeleka kwebhande lesikhathi elixhumanisa i-crankshaft ne-camshaft kuba yinto engalawuleki, okwenza izikhathi zokuvula nokuvala kwama-valve okungenisa nawokukhipha umoya zingavumelani nokunyakaza kwe-piston, okungase kuholele ezingozini ezinkulu ezifana nokugoba noma ukuphuka kwama-valve yi-piston, okubangela umonakalo omkhulu ezingxenyeni zangaphakathi zenjini (njenge-valve, izihlalo zama-valve, ama-piston, njll.), ngezindleko zokulungisa eziphezulu kakhulu ngisho nenjini.
Okubangela ukukhiqizwa kwamandla kagesi okungavamile: Ijenereyitha iqhutshwa yibhande. Ukulimala kwe-pulley ye-tensioner kubangela ukuthi ibhande lishelele noma libe nokucindezeleka okwanele, okuvimbela ijenereyitha ukuthi isebenze ngesivinini esizinzile, okuholela ekukhiqizweni kwamandla okwanele noma ekukhiqizweni okungazinzile. Lokhu kuzothinta ngqo ukusebenza okuvamile kwemishini kagesi yangaphakathi (njengezibani, umsindo) futhi kubangele ukuthi ibhethri lingashajwa ngokugcwele, okungase kuholele ekuphukeni kwemoto ngenxa yamandla anele ngesikhathi sokushayela ngokuhamba kwesikhathi.
Okubangela ukushisa kakhulu kwenjini: Ibhande lejenereyitha livame futhi ukushayela iphampu yamanzi. Ukulimala kwe-pulley ye-tensioner kubangela ukuthi ibhande lishelele noma libe nokucindezeleka okwanele, okuholela ekujikelezeni kabi kwe-coolant kanye nokungakwazi kwenjini ukuqeda ukushisa ngempumelelo, okubangela ukushisa kakhulu kwenjini. Ukushisa okuphezulu okuqhubekayo kuzokhulisa ukuguguleka kwezingxenye zangaphakathi zenjini futhi kuholele nasekuhlulekeni kwemishini njengokudonsa udonga lwesilinda kanye nokuguqulwa kwekhanda lesilinda.
Ukukhiqiza imisindo engajwayelekile kanye nokusheshisa: I-pulley ye-tensioner eyonakele izokhiqiza imisindo engavamile esobala, ikakhulukazi lapho imoto ishesha kakhulu noma ifinyelela isivinini esingaba ngu-1500 rpm, umsindo uzokhula kakhulu. Ngesikhathi esifanayo, ngenxa yokwehla kokusebenza kahle kokudlulisa amandla, imoto ingase ibhekane nokusheshisa. Ukusheshisa ukuguguleka kwebhande kanye nokwehluleka kwesistimu: Uma ibhande lisesimweni sokuxega, lizoba nokungqubuzana okungajwayelekile ne-pulley, okubangela ukuba izinga lokuguguleka kwalo lidlule kakhulu izinga elijwayelekile futhi kudingeke ukushintshwa kusenesikhathi. Ezimweni ezimbi kakhulu, uma i-pulley ecindezelayo ithola ukubanjwa noma ukuphuka kwebhereyi, ibhande lizohluleka ngokuphelele ukusebenza, okuholela ekuhlulekeni okuphelele kwezinhlelo ezihlobene (njengezinjini, amaphampu amanzi, njll.).
Ekuphetheni, yize i-pulley ecindezelayo yejenereyitha iyinto encane, umonakalo wayo ungathinta lonke uhlelo, uthinte kakhulu ukusebenza kwamandla emoto, ukonga, kanye nokuphepha kwayo. Uma kutholakala noma yiziphi izimpawu ezingavamile ezingenhla, imoto kufanele imiswe ngokushesha ekusetshenzisweni futhi ilungiswe ngobungcweti. Ezimweni ezidingekayo, ibhande lesikhathi, ibhande lejenereyitha, nezinye izingxenye kufanele nazo zishintshwe ndawonye.
