Umsebenzi wevili elixinayo kunye nevili elingasebenziyo lejenereyitha
Kwinkqubo yokuqhuba izixhobo ze-injini, i-tensioner pulley kunye ne-idler pulley zizinto ezimbini ezibalulekileyo ezinemisebenzi eyahlukeneyo. Zizonke, ziqinisekisa ukusebenza okuzinzileyo nokufanelekileyo kwebhanti.
Umsebenzi we-pulley ye-tensioner
Umsebenzi ophambili we-tensioner pulley kukulungisa ngokuzenzekelayo uxinzelelo lwebhanti, ukuqinisekisa ukuba ibhanti isoloko ikwimeko efanelekileyo yokusebenza. Isebenzisa izipringi zangaphakathi okanye iindlela ze-hydraulic ukuze ihlawule ngokuzenzekelayo uxinzelelo olusekelwe kubude okanye ukuguguleka kwebhanti, ngaloo ndlela:
Ukuthintela ibhanti ukuba ingatyibiliki okanye ingatyibiliki amazinyo ngenxa yokuba ikhululeke kakhulu;
Ukuphepha ukuba ibhande lingakhawulezisi ukuguguleka okanye ukwandisa umthwalo wenjini ngenxa yokuba ixinene kakhulu;
Ukunciphisa ukungcangcazela kunye nengxolo kwinkqubo yokudlulisa kunye nokuphucula uzinzo lwenkqubo.
Ngenxa yokwaluphala kwezinto ezingaphakathi ezidambisayo kunye nezipringi, ixesha lokuphila kwe-tensioner pulley lidla ngokufana nelebhanti. Kucetyiswa ukuba ibhande litshintshwe kunye nalo ukuze kuthintelwe ukungaphumeleli okulandelayo.
Umsebenzi we-pulley ye-idler
Umsebenzi ophambili we-idler pulley kukutshintsha indlela yokudlulisela ibhanti, endaweni yokudlulisa amandla okanye ukulungisa uxinzelelo. Imisebenzi yayo ethile ibandakanya:
Ukutshintsha icala lebhanti: ukuvumela ibhanti ukuba idlule izinto ezintsonkothileyo zenjini (ezifana nee-air conditioner, iimpompo zamanzi, iijenereyitha, njl.njl.);
Ukwandisa i-engile yokusonga: ukwandisa indawo yoqhagamshelwano phakathi kwebhanti kunye ne-pulley, ukuphucula ukusebenza kakuhle kothumelo, kunye nokunciphisa umngcipheko wokutyibilika;
Ukunciphisa ukungcangcazela kwebhanti: ukubonelela ngenkxaso ephakathi ekudlulisweni komgama omde, okwenza ibhanti isebenze kakuhle;
Ayitshintshi umlinganiselo wokudluliselwa: i-pulley ye-idler itshintsha icala kuphela, ngaphandle kokuchaphazela umlinganiselo wokudluliselwa kwamandla.
I-pulley ye-idler idla ngokufakwa phakathi kwee-pulley ezimbini eziqhubayo okanye eziqhutywayo. Xa iibheringi ze-pulley ye-idler ziphela, kunokubakho izandi ezingaqhelekanga okanye ukungcangcazela, okufuna ukutshintshwa ngexesha elifanelekileyo.
Ukonakala kwi-pulley ye-generator tensioner (ngamanye amaxesha ebizwa ngokuba yi-pulley ye-idler) kunokuba nemiphumo emibi kakhulu kwindlela eqhelekileyo yokusebenza kwesithuthi, ikakhulu okuchaphazela inkqubo yexesha lenjini, inkqubo yokutshaja, kunye nenkqubo yokupholisa.
Iziphumo eziphambili
Okubangela ukuphazamiseka kwexesha lenjini: I-tensioner pulley inoxanduva lokugcina uxinezeleko olufanelekileyo lwebhanti. Nje ukuba yonakele, ibhanti iya kutyhafa, ityibilike, okanye iphambuke, iphazamise ngokuthe ngqo ukusebenza ngokuchanekileyo kwenkqubo yexesha lenjini, nto leyo ebangela ukuba amazinyo exesha atsibe. Oku kuya kubangela ukuphazamiseka okukhulu kwexesha, okukhokelela ekushukumeni kwenjini, ubunzima bokutsha, kwanokungakwazi kwesithuthi ukuqala.
Ukubeka emngciphekweni umonakalo omkhulu kwinjini: Ukuba i-tensioner pulley ye-timing belt yonakele, imeko iba mandundu ngakumbi. Uxinzelelo lwe-timing belt edibanisa i-crankshaft kunye ne-camshaft alulawuleki, nto leyo ebangela ukuba amaxesha okuvula nokuvala kwee-intake kunye nee-exhaust valves angahambelani nokuhamba kwe-piston, nto leyo enokubangela iingozi ezinkulu ezifana nee-valve ezigotywayo okanye ezaphukileyo yi-piston, nto leyo ebangela umonakalo omkhulu kwiindawo zangaphakathi zenjini (ezifana nee-valve, izitulo zee-valve, ii-piston, njl.njl.), kunye neendleko zokulungisa eziphezulu kakhulu kunye nenjini.
Okubangela ukuveliswa kwamandla ejenereyitha ngendlela engaqhelekanga: Ijenereyitha iqhutywa yibhanti. Ukonakala kwe-pulley ye-tensioner kubangela ukuba ibhande lityibilike okanye libe noxinzelelo olwaneleyo, okuthintela ijenereyitha ekusebenzeni ngesantya esizinzileyo, okubangela ukuveliswa kwamandla okunganelanga okanye ukuphuma okungazinzi. Oku kuya kuchaphazela ngqo ukusebenza okuqhelekileyo kwezixhobo zombane zangaphakathi (ezifana nezibane, isandi) kwaye kubangele ukuba ibhetri ingatshajwa ngokupheleleyo, okunokubangela ukuba isithuthi singasebenzi kakuhle ngenxa yokungabikho kwamandla aneleyo ngexesha lokuqhuba ngokuhamba kwexesha.
Okubangela ubushushu obugqithisileyo benjini: Ibhanti yejenereyitha idla ngokuqhuba ipompo yamanzi. Ukonakala kwe-tensioner pulley kubangela ukuba ibhande lityibilike okanye libe noxinzelelo olwaneleyo, okubangela ukujikeleza kakubi kwe-coolant kunye nokungakwazi kwenjini ukucima ubushushu ngokufanelekileyo, okubangela ubushushu obugqithisileyo benjini. Ubushushu obuphezulu obuqhubekayo buya kwenza kube nzima ukuguguleka kweendawo zangaphakathi zenjini kwaye bukhokelele nakwiingxaki zoomatshini ezifana nokutsalwa kodonga lwesilinda kunye nokuguqulwa kwentloko yesilinda.
Ukuvelisa iingxolo ezingaqhelekanga kunye nokukhawulezisa: I-pulley ye-tensioner eyonakeleyo iya kuvelisa iingxolo ezingaqhelekanga ezicacileyo, ingakumbi xa imoto ikhawuleza kakhulu okanye ifikelela kwisantya esimalunga ne-1500 rpm, ingxolo iya kwanda kakhulu. Kwangaxeshanye, ngenxa yokuncipha kokusebenza kakuhle kokudlulisa amandla, imoto inokukhawulezisa. Ukuguguleka kwebhanti okukhawulezileyo kunye nokusilela kwenkqubo: Xa ibhanti ikwimeko yokungakhathali, iya kuba nokungqubana okungaqhelekanga ne-pulley, okubangela ukuba izinga layo lokuguguleka lidlule kakhulu kwinqanaba eliqhelekileyo kwaye lifune ukutshintshwa kwangethuba. Kwiimeko ezigqithisileyo, ukuba i-pulley exineneyo ifumana ukuxhuzula okanye ukwaphuka kwebhere, ibhanti iya kusilela ngokupheleleyo ukusebenza, nto leyo ekhokelela ekuphulweni ngokupheleleyo kweenkqubo ezinxulumene noko (ezifana neejenereyitha, iimpompo zamanzi, njl.njl.).
Ukuqukumbela, nangona i-pulley exinayo yejenereyitha incinci, umonakalo wayo unokuchaphazela yonke inkqubo, uchaphazele kakhulu ukusebenza kwamandla esithuthi, ukonga, kunye nokhuseleko. Ukuba kukho naziphi na iimpawu ezingaqhelekanga ezichazwe apha ngasentla, imoto kufuneka iyekwe ngoko nangoko ukuba isetyenziswe kwaye ilungiswe ngobuchule. Kwiimeko eziyimfuneko, ibhanti yexesha, ibhanti yejenereyitha, kunye nezinye izinto kufuneka zitshintshwe kunye.
