Umphezulu osebenzayo we-taper ring yi-tapered surface ene-taper encinci (i-angle ye-cone ye-taper ye-90 ye-injini ye-diesel yi-2 °), kunye necandelo lomnqamlezo li-trapezoidal. Emva kokuba i-cylinder ifakwe kwindandatho, kuphela umgca wangaphandle ongaphantsi kwendandatho udibanisa nodonga lwe-cylinder, okwandisa uxinzelelo loqhagamshelwano kumphezulu kunye nokuphucula ukusebenza kunye nokutywinwa. Kwangaxeshanye, i-oyile scraping ukusebenza ilungile xa isihla, kwaye ngenxa "ye-oyile wedge" isiphumo somgangatho othambekileyo xa unyuka, inokudada kwifilimu yeoli kwaye ibe nefuthe lokusasaza ngokulinganayo ioyile yokuthambisa. Ngoko ke, nangona uxinzelelo loqhagamshelwano luphezulu, aluyi kubangela ukunxiba kwe-fusion.

Xa ufaka i-taper ring, kukho imfuneko yolwalathiso, kwaye akufanele ifakwe ngasemva, kungenjalo iya kubangela ukuvuza kweoli enzulu (i-oyile yepompo), ukwandisa ukusetyenziswa kweoli yokuthambisa kunye ne-carbon deposits kwi-injini. Udibaniso oluchanekileyo kufuneka lube: isiphelo esincinci se-taper ring ifakwe ijonge phezulu (isiphelo esincinci se-taper ye-90 ye-injini ye-diesel ibhalwe ngegama elithi "上", ukuba uphawu lwe-taper endala alucacanga. , isiphelo esikhazimlisiweyo sesangqa sangaphandle kufuneka sijonge phantsi) . Umsesane we-taper awufanelekanga kwindandatho yokuqala yomoya, kuba umsesane wokuqala womoya unoxinzelelo olukhulu lokutsha. Ukuba isetyenziswe njengeringi yokuqala yomoya, inokutyhalelwa kude nodonga lwesilinda kwaye iphulukane nesiphumo sayo sokutywinwa.

2 Izangqa eziphothiweyo

I-cross-section yeringi ephothiweyo i-asymmetrical, kwaye umda ophezulu wesangqa sangaphakathi se-ring is grooved (njengamakhonkco omoya wesibini kunye nesesithathu se-4125A injini ye-diesel), okanye i-chamfered (njengawo onke amakhonkco omoya injini yedizili eyi-4115T); Kukho kwakhona iigrooves okanye ii-chamfers kumda ongezantsi weringi yangaphandle yeringi. Ngenxa yokuba icandelo lendandatho li-asymmetrical kwaye i-elastic force ayilingani, iya kujika ngokwayo emva kokufaka i-cylinder. Umphandle wesangqa ngumphezulu ocociweyo onomphezulu omncinci kunye nomzantsi omkhulu, onxibelelana ngomgca kunye nodonga lwesilinda, kwaye unxibelelana ngomgca kunye ne-ring groove, kwaye usondele kwindawo ephezulu kunye nesezantsi. i-ring groove. Oku akugcini nje ngokusebenza kakuhle kunye nokutywinwa, kodwa kunciphisa impembelelo kunye nokunxiba kwi-groove ye-ring, kunye nokukhuhla kwe-oyile kunye nokusebenza kokuhanjiswa kweoli nako kungcono. Ukufakwa kwendandatho ye-twist kufana nendandatho ye-taper, kwaye kukho imfuneko yolwalathiso, kwaye ayikwazi ukufakwa ngasemva, ngaphandle koko kuya kubangela ukuba ioli iqhube phezulu. Icala elingaphakathi le-grooved okanye i-chamfered yeringi ye-torsion kufuneka ifakwe ijonge phezulu; icala elingaphandle elinomgobo okanye eline-chamfered kufuneka lifakwe lijonge ezantsi. Umsesane ojijekileyo awufanelekanga kwindandatho yokuqala yomoya. Njengeringi ye-taper, ukuba i-air ring yokuqala isetyenzisiwe, inokutyhalwa kude nodonga lwesilinda kwaye ilahlekelwe yimpembelelo yayo yokutywinwa.

3 amakhonkco omphanda

Umphandle wangaphandle wendandatho ye-barrel ijikeleze kwaye yodwa emva kokusila, elingana nesimo sokuqala secandelo loxande emva kokugijima-ngaphakathi. Emva kokufakwa kwi-cylinder, ihambelana nomgca we-cylinder, kunye nokunyakaza okunyukayo kunye nokuhla kunempembelelo yokwenza ifilimu yeoli. Iqiniswe ngesantya esiphezulu kunye namandla aphezulu ehashe. Isetyenziswa kakhulu kwi-injini, njengentsimbi yokuqala yegesi. Izinto eziqhelekileyo ziyi-rectangular cross-section barrel rings, i-trapezoidal barrel rings enye okanye i-trapezoidal barrel rings. Xa ufaka, icala elinophawu kufuneka lijongane nomphezulu wepiston, ngaphandle koko kulula ukubangela ukungaphumeleli njengokutywinwa okungahambi kakuhle, uxinzelelo lwe-cylinder ephantsi, ukwanda kokusetyenziswa kweoli, kunye nobunzima bokuqalisa.

Izangqa ezi-5 ezixande

Amakhonkco angama-Rectangular abizwa ngokuba ngamakhonkco acwebileyo, alula ukwenza, abe nommandla omkhulu wokudibanisa kunye nodonga lwe-cylinder, kwaye abe nefuthe elinamandla lokutshatyalaliswa kobushushu. Okwangoku zezona zisetyenziswa kakhulu amakhonkco episton. Kulula ukuyifaka, ngaphandle kwayo nayiphi na into, ingasetyenziswa njengeyokuqala, i-air rings yesibini neyesithathu. Kodwa xa i-piston iphinda ibuyisela, inomsebenzi wokupompa ioli, oko kukuthi, xa i-piston iphinda iphinda ibuyele, i-piston ring icinezela ioli kwi-groove ye-ring groove ukuya kwigumbi lokutsha kanye, kwaye i-oyile iphonswa ngokulula kwigumbi lokutshisa. Xa umsesane we-rectangular uxutywe kunye ne-tapered ring okanye umsesane ojijekileyo, umsesane woxande usetyenziswa njengeringi yokuqala yegesi.

6 amakhonkco trapezoidal

Iringi yetrapezoidal isoloko isetyenziswa njengesangqa somoya sokuqala senjini yedizili enomthwalo omkhulu. Iyakwazi ukutshintsha umsantsa phakathi kweringi kunye negroove yeringi xa ipiston ijiwulwa ngasekhohlo nasekunene okanye isithuba phakathi kweendawo zokuvula umsesane iyatshintsha, ngaloo ndlela ikhupha ioyile yecoke kuyo, enokuthi ithintele umsesane wepiston ukuba ungabambeki ngenxa yentsini. .
