Qhagamshela ipiston kunye ne crankshaft, kwaye uthumele amandla kwipiston kwi crankshaft, ukuguqula intshukumo ebuyelayo yepiston ibe yintshukumo ejikelezayo yecrankshaft.
Iqela lokudibanisa intonga liqulunqwe ngumzimba wentonga yokudibanisa, intonga yokudibanisa isiphelo esikhulu, intonga yokudibanisa i-bushing encinci, intonga yokudibanisa i-bush enkulu kunye ne-bolts yokudibanisa (okanye izikrufu). Iqela lokudibanisa intonga lixhomekeke kumandla wegesi ukusuka kwipiston yepiston, i-swing yayo kunye nokubuyisela amandla angenayo e-inertial yeqela lepiston. Ubukhulu kunye nolwalathiso lwala mandla luyatshintsha ngamaxesha athile. Ngoko ke, intonga yokudibanisa ixhomekeke kwimithwalo eguqukayo efana noxinzelelo kunye noxinzelelo. Intonga yokudibanisa kufuneka ibe namandla okwaneleyo okukhathala kunye nokuqina kwesakhiwo. Amandla angonelanga okudinwa adla ngokubangela ukuba umzimba wentonga yokudibanisa okanye ibholithi yokudibanisa intonga iphuke, okukhokelela kwingozi enkulu yomonakalo kumatshini wonke. Ukuba ukuqina akwanelanga, kuya kubangela ukugoba komzimba wentonga kunye nokuguqulwa okungaphandle komjikelo wesiphelo esikhulu sentonga yokudibanisa, okukhokelela ekunxityweni kwepiston, isilinda, ukuthwala kunye nepini yokukrala.
Isakhiwo kunye nokwakheka
Umzimba wentonga yokudibanisa iqulethwe ngamacandelo amathathu, inxalenye edibaniswe nepiston yepiston ibizwa ngokuba yisiphelo esincinci sentonga yokudibanisa; inxalenye edityaniswe ne-crankshaft ibizwa ngokuba sisiphelo esikhulu sentonga yokudibanisa, kwaye inxalenye edibanisa isiphelo esincinci kunye nesiphelo esikhulu ibizwa ngokuba ngumzimba wentonga yokudibanisa.
Isiphelo esincinci sentonga yokudibanisa ubukhulu becala sisakhiwo esincinci se-annular. Ukuze kuncitshiswe ukunxiba phakathi kwentonga yokudibanisa kunye nepiston yepiston, i-bronze bushing enodonga oluncinci icinezelwe kumngxuma omncinci wokuphela. I-drill okanye i-grooves ye-mill kwintloko encinci kunye ne-bushing ukuvumela i-oyile yokutshiza ukuba ingene kwiindawo zokukhwela i-rubricating bushing kunye ne-piston pin.
I-shaft yokudibanisa yintonga ende, kwaye iphinda ixhomekeke kumandla amakhulu ngexesha lomsebenzi. Ukuthintela ukugoba kunye nokukhubazeka, umzimba wentonga kufuneka ube nobulukhuni okwaneleyo. Ngenxa yesi sizathu, ininzi yokudibanisa i-shafts ye-injini yemoto isebenzisa amacandelo a-I-shaped, anokunciphisa ubunzima kunye nokuqina okwaneleyo kunye namandla, kwaye amacandelo afana ne-H asetyenziswa kwiinjini eziphezulu. Ezinye ii-injini zisebenzisa isiphelo esincinci sentonga yokudibanisa ukutshiza i-oyile ukupholisa ipiston, kwaye umngxuma odlulayo kufuneka ugrunjwe kwicala lelongitudinal yomzimba wentonga. Ukuze ugweme ukuxinzezeleka koxinzelelo, uxhulumaniso phakathi kwentonga yokudibanisa kunye nesiphelo esincinci kunye nesiphelo esikhulu samkela inguqu egudileyo ye-arc enkulu.
Ukuze kuncitshiswe i-vibration ye-injini, ukuhluka komgangatho we-cylinder nganye intonga yokudibanisa kufuneka inqunyelwe kuluhlu oluncinci. Xa kuhlanganiswa i-injini kumzi-mveliso, ngokuqhelekileyo ihlelwa ngokobunzima beencam ezinkulu nezincinci zentonga yokudibanisa kwiigram. Intonga yokudibanisa yeqela.
Kwi-injini yohlobo lwe-V, iisilinda ezihambelanayo zemigca ekhohlo kunye neyokunene yabelana ngepini ye-crank, kunye neendidi ezidibanisayo zineentlobo ezintathu: iintonga zokudibanisa ezihambelanayo, iifolokhwe zokudibanisa iintambo kunye neentonga eziphambili kunye nezincedisayo.
Uhlobo oluphambili lomonakalo
Iifom zomonakalo eziphambili zokudibanisa iintonga kukuphuka kokukhathala kunye nokuguqulwa okugqithisileyo. Ngokuqhelekileyo i-fractures yokukhathala ifumaneka kwiindawo ezintathu zoxinzelelo oluphezulu kwintonga yokudibanisa. Iimeko zokusebenza zentonga yokudibanisa zifuna intonga yokudibanisa ibe namandla aphezulu kunye nokumelana nokukhathala; Kukwafuna ukuqina okwaneleyo kunye nokuqina. Kwiteknoloji yokudibanisa intonga yendabuko, izinto eziqhelekileyo zisebenzisa intsimbi ecinyiweyo kunye neyomsindo njengentsimbi ye-45, i-40Cr okanye i-40MnB, enobulukhuni obuphezulu. Ngoko ke, izinto ezintsha zokudibanisa izintonga eziveliswe ziinkampani zemoto zaseJamani ezifana neC70S6 i-carbon microalloy ephezulu engacinywanga kunye nentsimbi epholileyo, i-SPLITASCO series Forged steel, i-FRACTIM yentsimbi eyenziwe ngentsimbi kunye ne-S53CV-FS yentsimbi, njl njl. ). Nangona intsimbi ye-alloy inamandla aphezulu, inomdla kakhulu kuxinzelelo loxinzelelo. Ngoko ke, iimfuno eziqinileyo zifunekayo kwimilo yentonga yokudibanisa, i-fillet engaphezulu, njl., kwaye ingqalelo kufuneka ihlawulwe kumgangatho wokucubungula umphezulu wokuphucula amandla okukhathala, ngaphandle koko ukusetyenziswa kwentsimbi ephezulu ye-alloy ayiyi kufezekisa oyifunayo. isiphumo.
