Nzvimbo yekushanda ye ring ring inzvimbo yakasvibiswa ine taper duku (iyo taper ring cone angle ye 90 series diesel injini ndeye 2 °), uye chikamu chemuchinjikwa ndicho trapezoidal. Mushure mokunge cylinder yaiswa mumhete, iyo chete yekunze yakadzika mupendero wemhete inosangana nemadziro evhavha, iyo inowedzera kusangana kwekumanikidza pamusoro pepamusoro uye inovandudza kumhanya-mukati uye kuvhara kushanda. Panguva imwecheteyo, kukwesha kwemafuta kwakanaka kana kuchidzika, uye nekuda kwe "oil wedge" mhedzisiro yenzvimbo yakarerekera kana ichikwira kumusoro, inogona kuyangarara pafirimu remafuta uye kuita mhedzisiro yekugovera zvakaenzana mafuta ekuzora. Naizvozvo, kunyangwe kudzvinyirirwa kwekusangana kwakakwira, hazvizokonzerese kupfeka kwefusion.

Pakuisa taper mhete, pane chinodiwa chinotungamira, uye haifanirwe kuisirwa kumashure, zvikasadaro zvinokonzeresa kudonha kwemafuta (pombi mafuta), kuwedzera kushandiswa kwemafuta ekuzora uye kabhoni deposits muinjini. Iko kuungana kwakakodzera kunofanirwa kuve: iyo diki yekupedzisira yemhete ye taper yakaiswa yakatarisa kumusoro (kumucheto kudiki kweiyo taper ring ye90 series dizeli injini yakanyorwa nezwi rekuti "上", kana mucherechedzo wekare taper mhete isina kujeka. , mugumo wakakwenenzverwa wedenderedzwa rekunze unofanira kutarisana pasi) . Iyo taper mhete haikodzeri mhete yemhepo yekutanga, nekuti mhete yemhepo yekutanga inotakura kumanikidza kukuru kwekupisa. Kana ikashandiswa semhete yemhepo yekutanga, inogona kusundidzirwa kure nemadziro ecylinder uye kurasikirwa nekuisa chisimbiso kwayo.

2 Twisted Rings

Muchinjikwa-chikamu chemhete yakamonyoroka ndeye asymmetrical, uye mupendero wepamusoro wedenderedzwa remukati remhete wakaiswa grooved (seyechipiri neyechitatu mhete dzemhepo dze4125A injini yedhiziri), kana chamfered (senge mhete dzese dzemhepo dze. iyo 4115T injini yedhiziri); Kune zvakare grooves kana chamfers pamucheto wezasi wemhete yekunze yemhete. Nekuti chikamu chemhete chine asymmetrical uye iyo elastic simba haina kuenzana, inozomonyoroka yega mushure mekuisa silinda. Iyo yekunze yemhete inzvimbo yakatsetseka ine diki kumusoro uye pasi hombe, iyo iri mumutsara wakabatana necylinder madziro, uye zvakare mumutsara wekubatana ne ring groove, uye iri padhuze nepamusoro nepasi pekupedzisira nzvimbo dze. ring groove. Izvi hazvisi chete zvine kunaka kwekumhanya-mukati uye kuisa chisimbiso kuita, asi zvakare kunoderedza kukanganisa uye kupfeka pane ring groove, uye kukwesha kwemafuta uye kuita kwemafuta ekugovera kuri nani zvakare. Kuiswa kwemhete yakamonyoroka kwakafanana neyeye taper mhete, uye kunewo chinodiwa chekutungamira, uye haigone kuiswa kumashure, kana zvisina kudaro ichaita kuti mafuta afambe. Iyo yemukati grooved kana chamfered divi re torsion mhete inofanira kuiswa yakatarisa kumusoro; rutivi rwekunze rwakarukwa kana kuti chamfered runofanira kuiswa rwakatarisa pasi. Mhete yakamonyoroka hainawo kukodzera yekutanga mhete yemhepo. Kufanana nemhete yematepi, kana mhete yekutanga yemhepo ikashandiswa, inogona kusundirwa kure nemadziro ecylinder uye kurasikirwa nekuisa chisimbiso kwayo.

3 dhiramu zvindori

Nzvimbo yekunze yemhete-yakaita denderedzwa yakatenderedza uye yega mushure mekugaya, iyo yakaenzana neyekutanga mamiriro erectangular chikamu mushure mekumhanya-mukati. Mushure mekuiswa muhumburumbira, iri mumutsara wekubatana nemadziro ecylinder, uye mafambiro ekumusoro uye pasi ane mhedzisiro yekugadzira firimu remafuta. Yakasimbiswa nekumhanya kukuru uye simba rebhiza rakakwirira. Inoshandiswa zvakanyanya muinjini, seyekutanga gasi mhete. Izvo zvinowanzoita rectangular cross-section barrel rings, single-sided trapezoidal barrel rings kana kaviri-sided trapezoidal barrel mhete. Paunenge uchiisa, rutivi rune mucherechedzo runofanira kutarisana nepamusoro pepiston, zvikasadaro zviri nyore kukonzera kukundikana kwakadai sekusaisa chisimbiso, kuderera kwecylinder pressure, kuwedzera kushandiswa kwemafuta, uye kuoma kutanga.

5 rectangular zvindori

Rectangular zvindori zvinonziwo flat rings, izvo zviri nyore kugadzira, zvine nzvimbo yakakura yekubatana ne cylinder wall, uye ine simba rakasimba rekupisa kupisa. Parizvino ndiwo anonyanya kushandiswa piston mhete. Zviri nyore kuisa, pasina zvakadaro, inogona kushandiswa seyekutanga, yechipiri uye yechitatu mhepo mhete. Asi apo piston inodzorera, inenge iine basa rekupomba mafuta, kureva kuti, kana piston yangodzoka, rin'i yepiston inotsikirira mafuta mumhete yegorofu kukamuri rinopisa kamwe chete, uye mafuta anoputirwa nyore nyore muimba inopisa. Kana mhete ine rectangular yakasanganiswa nemhete yakatemwa kana mhete yakamonyoroka, rin'i ine rectangular inoshandiswa seyekutanga gasi mhete.

6 trapezoidal zvindori

Iyo trapezoidal mhete inowanzoshandiswa seyekutanga mhete yemhepo yeinjini yedhiziri ine mutoro wakakwira. Inogona kushandura gaka riri pakati pemhete nemhete groove kana piston ichizungunuka kuruboshwe nekurudyi kana gaka riri pakati pemazaru emhete richichinja, nekudaro kusvina mafuta ecoke mairi, izvo zvinogona Inodzivirira mhete yepiston kuti isabatirwe nekuda kwekugwinya. .
