Kodi chogwirira ndodo yolumikizira magalimoto ndi chiyani?
Pini ya crankshaft (yomwe imadziwika kuti "pin yaying'ono") ndi gawo lofunika kwambiri lothandizira injini. Imayikidwa pakati pa ndodo yolumikizira ndi chojambulira cha ndodo yolumikizira ya crankshaft, yomwe imagwira ntchito yolumikiza pisitoni, kulumikiza ndodo ndi crankshaft, komanso kuthandizira kutumiza mphamvu ndi kusintha kwa kayendedwe.
Chepetsani kukangana: Pogwiritsa ntchito zipangizo zosamalidwa bwino, kukangana kotsetsereka pakati pa ndodo yolumikizira ndi crankshaft kumachepa.
Thandizo ndi malo: Onetsetsani kuti ndodo yolumikizira ikuzungulira mozungulira crankshaft panthawi yothamanga kwambiri.
Kutaya kutentha: Kutumiza kutentha komwe kumachitika chifukwa cha kukangana kumutu waukulu wa ndodo yolumikizira kuti kupewe kutentha kwambiri komwe kumachitika m'deralo.
Kupereka mafuta ndi mafuta: Mabuku ena olumikizira ndodo amapangidwa ndi mipata ya mafuta ndi mabowo amafuta, omwe amapereka mafuta kukhoma lamkati la pistoni kuti azizire pistoni.
Makhalidwe a kapangidwe kake
Kapangidwe ka zinthu: Kawirikawiri kamakhala ndi zitsulo kumbuyo + aloyi yochepetsera kuwonongeka (monga aloyi ya Babbitt, aloyi yokhala ndi aluminiyamu yambiri, bronze ya lead, ndi zina zotero).
Kukhuthala: Chitsulo chakumbuyo chili pafupifupi 1–3mm, ndipo gawo lochepetsa kuwonongeka ndi pafupifupi 0.3–0.7mm.
Kapangidwe ka magawo: Kagawika m'magawo apamwamba ndi otsika, ndipo njira yokhazikitsira ndi chizindikiro ziyenera kudziwika panthawi yokhazikitsa.
Kapangidwe ka malo: Pali malo oonekera kapena mabowo kuti aletse kuzungulira kapena kuyika kolakwika.
Mayina ndi masiyanidwe ena odziwika bwino
"Kabuku kakang'ono": Dzina lake ndi chifukwa chakuti kabuku kolumikizira ndodo ndi kopyapyala kuposa kabuku kakang'ono ("kabuku kakang'ono"), ndipo ndi kakang'ono kukula kwake.
Kusiyana ndi magazini yayikulu:
Buku lalikulu (buku lalikulu): Limathandizira buku la crankshaft ndipo limakhazikika pa silinda. Kapangidwe kake nthawi zambiri kamakhala ndi mabowo ndi mipata yamafuta kuti mafuta aperekedwe, zomwe zimagwiritsidwa ntchito pothandizira mokhazikika.
Buku lolumikizira ndodo (buku laling'ono): Limatsatira kugwedezeka kobwerezabwereza kwa ndodo yolumikizira, yokhala ndi kapangidwe kosavuta. Ma injini ena othamanga kwambiri ali ndi utoto wowonjezera kukana kuwonongeka.
Mawonekedwe a zolakwika
Kutuluka kwakukulu: Kutsika kwa kuthamanga kwa mafuta ndi phokoso la "kugogoda kwa silinda".
Kusakwanira kwa malo: Kuwonongeka mofulumira, ndipo pazochitika zazikulu, kungayambitse "kutseka kwa crankshaft".
Phokoso losazolowereka: Vuto la connecting rod journal nthawi zambiri limaonekera ngati phokoso lomveka bwino la "kugogoda", makamaka lodziwika bwino panthawi yothamanga mwadzidzidzi.
Malangizo okonza
Mukasintha majenerali olumikizira ndodo, ndikofunikira kugwiritsa ntchito zofunikira zoyambirira kapena zofanana ndi majenerali enieni.
Kukhazikitsa kuyenera kutsatira mosamalitsa zofunikira za torque kuti kumangitse mabotolo a ndodo yolumikizira, ndikuwonetsetsa kuti zofunikira za msonkhano monga momwe jenali, chizindikiro, ndi momwe pisitoni imayendera ku giya yowerengera nthawi.
Pakukonza tsiku ndi tsiku, samalani ndi ubwino wa mafuta ndi nthawi yosinthira, chifukwa mafuta osakwanira adzapangitsa kuti jenereta iwonongeke mwachangu.
Mabuku olumikizira ndodo zamagalimoto (omwe amadziwika kuti "mabuku ang'onoang'ono") ndi zigawo zazikulu zolumikizira mu injini, zomwe zimayikidwa pakati pa mutu waukulu wa ndodo yolumikizira ndi buku la crankshaft. Ntchito zawo zazikulu zitha kufotokozedwa motere:
Chepetsani kukangana ndi kutha: Kudzera mu gawo la aloyi lochepetsa kutha (monga aloyi yoyera, aloyi yochokera ku aluminiyamu, ndi zina zotero), kukangana mwachindunji pakati pa mutu waukulu wa ndodo yolumikizira ndi crankshaft journal kumachepa, zomwe zimateteza zonse ku kutha kwambiri.
Thandizo ndi malo: Monga chotengera chotsetsereka, chimathandizira crankshaft journal, kuonetsetsa kuti kulumikizana kuli kokhazikika pakati pa ndodo yolumikizira ndi crankshaft, ndikusunga njira yolondola yoyendera.
Mphamvu yotumizira: Imasamutsa mphamvu ya mpweya ndi mphamvu yobwezera ya inertia yomwe imayendetsedwa ndi pistoni kupita ku crankshaft, zomwe zimapangitsa kuti kusintha kuchoka pa kuyenda kwa pistoni kupita ku kuyenda kozungulira kwa crankshaft kusinthe.
Kupaka mafuta ndi kuyeretsa kutentha:
Mitsempha ya mafuta ndi mabowo a mafuta pa nyuzipepala zimasonyeza bwino mafutawo, kupanga filimu yokhazikika ya mafuta, zomwe zimapangitsa kuti mafuta azitha kupakidwa;
Chitsulo chopyapyala chimayendetsa kutentha komwe kumapangidwa ndi kukangana kupita ku mutu waukulu wa ndodo yolumikizira, zomwe zimathandiza kuwononga kutentha, ndikuletsa kutentha kwambiri komwe kumachitika m'deralo.
Kuonjezera nthawi yogwira ntchito: Kudzera mu kapangidwe kosatha komanso koyenera, chepetsani kutha kwa injini, ndikuwonjezera kulimba kwa injini.
Majenerali olumikizira ndodo nthawi zambiri amagawidwa m'majenerali apamwamba ndi otsika. Jenerali yapamwamba ili ndi mipata yamafuta ndi mabowo amafuta operekera mafuta ku payipi yamkati kuti izizire; jenerali yapansi ilibe mipata yamafuta ndipo makamaka imatenga gawo lothandizira. Mukakhazikitsa, samalani ndi komwe kumachokera ma protrusions ndi miyezo ya torque, apo ayi, ingayambitse phokoso losazolowereka, kutentha kwa jenerali, kapena kutseka crankshaft.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
