Mphete yoyendetsera galimoto: Choteteza chosaoneka cha kukhazikika kwa injini
Mu "ufumu" wamakono wa injini ya galimoto, pali zinthu zambiri zosafunika koma zofunika kwambiri. Mphete yopondereza ndi imodzi mwa izo. Ili ngati "axial guard" yosalankhula yomwe imatsimikizira kuti injini ikugwira ntchito bwino. Ngati yalephera, ingayambitse kusintha kwa unyolo ndikuwopseza magwiridwe antchito abwinobwino a injini.
Ntchito yaikulu ya mphete yolumikizira
Mphete yopondereza, monga mtundu wa bearing yotsetsereka ya injini, imatenga udindo waukulu wothandizira crankshaft mozungulira. Panthawi yogwira ntchito ya injini, crankshaft simangofunika kuzungulira mwachangu komanso imapanga axial thrust chifukwa cha kuyenda kobwerezabwereza kwa gulu la piston connecting rod, gear transmission, ndi zina zotero. Ngati siili yocheperako, crankshaft idzakumana ndi axial movement, zomwe zidzasokoneza malo oyenera pakati pa zigawo zamkati za injini. Mphete yopondereza imasamutsa katundu wa axial kupita ku cylinder block kudzera pafupi ndi pamwamba pa crankshaft, kupereka chithandizo chokhazikika cha axial cha crankshaft ndikuchepetsa kwambiri kuyenda kwake kwa axial. Kawirikawiri, kusiyana kumeneku kuyenera kulamulidwa mkati mwa 0.35mm kuti kupewe kuyenda kwambiri kwa axial kwa crankshaft, komwe kungayambitse kusokoneza pakati pa ndodo yolumikizira ndi khoma la cylinder, piston ndi valavu, ndi zina zotero, ndikuwonetsetsa kuti magawo onse osuntha akugwira ntchito bwino.
Kuwonjezera pa kuthandizira ndi kuyika malo a axial, mphete yoyendetsera mafuta ilinso ndi ntchito yothandizira pakukonza mafuta ndikuchepetsa kuwonongeka kwa kukangana. Pamwamba pake nthawi zambiri pamakhala mipata yamafuta. Pakagwira ntchito injini, mafuta amatha kupanga filimu yamafuta yosalekeza pamwamba pa malo olumikizirana pakati pa crankshaft ndi mphete yoyendetsera mafuta kudzera mu mipata yamafuta, kuchepetsa kuchuluka kwa kukangana ndikuchepetsa kuwonongeka kwachindunji pakati pa zitsulo, kukulitsa bwino moyo wa ntchito ya crankshaft ndi mphete yoyendetsera mafuta. Nthawi yomweyo, kapangidwe koyenera ka mipata yamafuta kumatsimikizira kuyenda bwino kwa mafuta oyendetsera mafuta ndipo kumapereka mafuta osalekeza pamalo okangana, kupewa kuwonongeka kwambiri ndi kutentha kwambiri kwa zigawo chifukwa cha mafuta osakwanira.
Pa camshaft, mainjini ena alinso ndi ma thrust rings, omwe amagwira ntchito mofanana ndi ma thrust rings a crankshaft, omwe amagwiritsidwa ntchito kuchepetsa kuyenda kwa camshaft, kuonetsetsa kuti valavu ikugwira ntchito molondola, komanso kusunga nthawi yolondola yotsegulira ndi kutseka ma valavu, motero kusunga mphamvu yotulutsa komanso kusunga mafuta a injini.
Zolakwika zomwe zimachitika kawirikawiri komanso zomwe zimayambitsa mphete zopondereza
Kuwonongeka kwambiri: Ichi ndi chimodzi mwa zolakwika zomwe zimachitika kawirikawiri pa mphete yopopera. Pakagwiritsidwa ntchito kwa nthawi yayitali, mphete yopopera imakanda nthawi zonse pamwamba pa crankshaft, pamodzi ndi kutentha kwambiri komanso kuthamanga kwambiri kwa injini, gawo losatha la alloy pamwamba pa mphete yopopera limatha pang'onopang'ono. Kuphatikiza apo, zizolowezi zoyipa za oyendetsa, monga kuthamanga mwachangu pafupipafupi, kuchepetsa liwiro, kapena kugwiritsa ntchito clutch m'malo osalowerera komanso otsika m'mphepete mwa nyanja, zidzapangitsa kuti mphamvu ya axial ya crankshaft ichuluke mwadzidzidzi, zomwe zimapangitsa kuti mphete yopopera iwonongeke. Ngati mafuta opaka mafuta ndi otsika kapena njira yamafuta yatsekedwa, zomwe zimapangitsa kuti mafuta asamayende bwino, zidzathandizanso kuti mphete yopopera iwonongeke.
Kukhazikitsa kolakwika: Kukhazikitsa mphete yoyendetsera mafuta kumakhala ndi zofunikira kwambiri pakuwongolera. Nthawi zambiri, pamwamba pa groove ya mafuta payenera kuyang'ana pa crankshaft kuti mafuta odzola azitha kulowa bwino pamwamba pa friction ndikupanga mafuta. Ngati njirayo yayikidwa molakwika, izi zimapangitsa kuti mafuta azikhala ochepa, ndipo mphete yoyendetsera mafuta ndi crankshaft sizingapange filimu yogwira ntchito bwino yamafuta, zomwe zimapangitsa kuti friction youma iwonongeke, zomwe zingayambitse kuwonongeka mwachangu kwa mphete yoyendetsera mafuta kapena ngakhale ablation. Nthawi yomweyo, ngati mphete yoyendetsera mafuta sinakhazikitsidwe bwino mu cylinder block kapena malo ogwirizana a crankshaft panthawi yokhazikitsa, mphete yoyendetsera mafuta ingasunthe ndikulephera kuchepetsa kuyenda kwa axial kwa crankshaft.
Kuchotsa ndi kuwonongeka: Mphete yopondereza ikawonongeka kwambiri kapena ikakhudzidwa ndi zinthu zosazolowereka, imatha kuchoka pamalo oikira ndikugwera mu poto yamafuta. Mphete yopondereza yochotsedwa idzataya mphamvu yake yopondereza pa crankshaft, zomwe zimapangitsa kuti crankshaft isunthe kwambiri, ndipo ikhoza kugundana ndi zinthu zina mu poto yamafuta, zomwe zimapangitsa kuti pakhale kuwonongeka kwina. Mwachitsanzo, munthawi yofulumira kwambiri, kukhudzana pakati pa clutch ndi flywheel kudzasamutsa mphamvu yayikulu. Ngati mphete yopondereza yawonongeka kwambiri ndipo singathe kupirira mphamvu ya axial, ikhoza kuchoka, motero kuyambitsa zizindikiro zosazolowereka kuchokera ku sensa ya crankshaft ndi alamu kuchokera ku kuwala kwa injini.
Kuzindikira ndi kuyankha ku zolakwika za mphete yolumikizirana
Pamene chitsulo chopondereza chalephera kugwira ntchito, injini nthawi zambiri imakhala ndi zizindikiro zina zosazolowereka. Ngati kuyenda kwa axial kwa crankshaft kuli kwakukulu kwambiri, kungayambitse phokoso losazolowereka panthawi yogwira ntchito kapena injini, makamaka posuntha magiya, kuthamanga kapena kutsika. Phokoso lidzakhala lodziwikiratu. Pakhoza kukhalanso zolakwika mu transmission system monga kulephera kwa clutch kapena kuvutika posuntha magiya. Pazochitika zazikulu, zingayambitse kuchepa kwa mphamvu ya injini ndi kugwiritsa ntchito mafuta molakwika.
Pozindikira vuto la thrust plate, njira ya tachometer ingagwiritsidwe ntchito kuzindikira kayendedwe ka axial ka crankshaft. Ngati kayendetsedwe kake kapitirira mtengo wokhazikika wa 0.35mm, mwina thrust plate yatha kapena yagwa. Vuto la thrust plate likatsimikizika, ndikofunikira kukonza ndikusintha nthawi yake. Pakusintha, zofunikira pakuyika ziyenera kutsatiridwa mosamala kuti zitsimikizire kuti njira ya thrust plate ndi yolondola ndipo yakhazikika bwino. Nthawi yomweyo, yang'anani ngati pali kuwonongeka kulikonse pamwamba pa thrust plate. Ngati kuli kofunikira, konzani kapena kusintha crankshaft. Pakuyendetsa tsiku ndi tsiku, zizolowezi zabwino zoyendetsera ziyenera kupangidwa, mafuta abwino nthawi zonse ayenera kusinthidwa, ndipo thrust plate ndi zida zina ziyenera kufufuzidwa malinga ndi kayendedwe kosamalira kuti apewe mavuto omwe angakhalepo asanachitike, kukulitsa moyo wa injini, ndikuwonetsetsa kuti kuyendetsa bwino komanso kosalala. Thrust plate, ngakhale yaying'ono, ndi gawo lofunikira kwambiri pakugwira ntchito bwino kwa injini. Kumvetsetsa ntchito yake ndi mawonekedwe ake olakwika kumatithandiza kusamalira bwino injini ya galimoto, kuzindikira ndi kuthetsa mavuto omwe angakhalepo panthawi yake, kukulitsa nthawi yogwira ntchito ya injini, ndikuwonetsetsa kuti kuyendetsa bwino komanso kosalala.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
