Injongo yokutywinwa kweoli kukubonelela ngokutywinwa phakathi kwe-crankshaft ejikelezayo nangaphandle.Iimpawu zeoyile zeClassical ziquka indlu yentsimbi ephethe umlebe wokutywina oguqukayo kwaye ikwabonelela ngomsebenzi wokutywina omileyo.Umlebe wokutywina wamatywina e-oyile udla ngokuveliswa ngezinto ze-elastomer, kwaye udibana nomphezulu we-shaft ejikelezayo.Ngale ndlela, umlebe ucinezelwa kumphezulu we-shaft ngokusebenzisa iringi yasentwasahlobo.Ngenxa yokunyakaza okujikelezayo, kukho i-gap yokutywina ye-approx.1 µm ekupheleni komlomo.I-oyile inokungena kulo msantsa, osebenza ukuthambisa umlomo wokutywina.
Uphuhliso oluqhubekayo kuyilo lwe-injini lukhokelela kwiimfuno ezihlala ziphezulu kolu hlobo lwesitywina se-oyile.Isantya esiphezulu se-injini kunye namaqondo obushushu e-oyile, ixesha elide phakathi kweenguqu ze-oyile kunye nezithambisi ezinezongezo zanamhlanje ezisabela ngokungqongqo ngezinto zokutywina zifuna izisombululo ezitsha nezihlala zihleli.Izinto eziphathekayo zeoli ye-oyile yexesha elizayo kuthiwa yi-POLYTETRAFLUOROETHYLENE okanye ngokulula i-PTFE.Ezi zinto zokwenziwa ziyaziwa ngokubanzi phantsi kwayo igama lokuthengisa i-polymer.
Ukruthakruthwano oluphantsi kunye nobuncinci bokusetyenziswa kwamandla zizinto ezilungileyo ezibonelelwa yi-PTFE oil seals.Ezi zitywina zingasetyenziswa ngaphandle kweengxaki kunye nokusebenza okomileyo okanye ukuthambisa okungonelanga.Izinto eziphathekayo ze-thermal, kunye noluhlu olusebenzayo lwe--130 ° C ukuya ku-200 ° C, alunakulinganiswa.Ngaphezu koko, i-PTFE ibonakaliswe kukuxhathisa kweekhemikhali eziphezulu kunye ne-torque ephantsi ephuke emva kokuma.
Xa ishushu, i-PTFE izama ukubuyela kwimo yayo yokuqala.Ngamanye amazwi: Isixhobo “sikhumbula” isimo saso sokuqala.Lo mcimbi waziwa njengempembelelo yememori yeplastiki, kwaye ivumela izitywina ukuba zakhiwe ngaphandle kokwenza ngathi intwasahlobo.Ngexesha lokwenziwa, umlebe wokutywina ufana nendandatho ecaba, ehlanganiswe kwindandatho yokuqinisa.Ngexesha lokudityaniswa kwi-shaft, umlebe wokutywina wokuqala osicaba uyakhula kwaye ugoqeke ukuze ungqinelane nedayamitha ye-shaft.Nje ukuba umlebe wokutywina ushushu ngexesha lokusebenza kwe-injini, izama ukubuyela kwisimo sayo sokuqala.
Izindlu zangaphandle zenziwe ngentsimbi engenasici.IRingi ye-O ye-fluoroelastomer iqinisekisa ukutywinwa okufanelekileyo okuzinzileyo.I-diameter yangaphakathi igxininise ngokugqibeleleyo kunye nobubanzi obungaphandle.Owona mlebe wokutywina wenziwa nge-PTFE ekwaziyo ukunxitywa kakhulu kunye nokukhuhlana okuphantsi.Isitywina esongezelelweyo sothuli (umlebe werabha okanye umcu ozivelisayo) ubonelela ngomqobo osebenzayo ngokuchasene namasuntswana angcolisayo.
