Piston assembly inosanganisirei?
Iyo piston gungano chikamu chakakosha cheinjini yemotokari, iyo inonyanya kuumbwa nezvinhu zvitanhatu zvinotevera:
1. Piston: Icho chikamu chekamuri yekupisa uye yakashongedzerwa nemhete dzinoverengeka dzekuisa mhete yepiston.
2. Piston mhete: Yakaiswa papiston kuti isimbise, kazhinji inoumbwa nemhete yegesi uye mhete yemafuta.
3. Piston yepini: Kubatanidza piston uye musoro muduku wepiston yekubatanidza tsvimbo, kune nzira mbiri dzekuzara kwakazara uye semi-inotenderera.
4. Piston yekubatanidza tsvimbo: tsvimbo yekubatanidza yepiston uye crankshaft, yakakamurwa kuva musoro mukuru uye musoro muduku kumativi ose maviri, musoro muduku wakabatanidzwa nepiston, musoro mukuru wakabatanidzwa kune crankshaft.
5. Kubatanidza tsvimbo kubereka: chikamu chekuzora chakaiswa mumusoro mukuru wetambo yekubatanidza.
6. Kubatanidza tsvimbo yebhaudhi: bhoti inogadzirisa kuguma kukuru kwetambo yekubatanidza pa crankshaft.
Piston mhete ndiyo yakakosha chikamu mukati meinjini yemafuta, iyo uye silinda, piston, silinda madziro pamwe chete kupedzisa chisimbiso chemafuta gasi. Injini dzemotokari dzinowanzo shandiswa dzine marudzi maviri einjini dzedhiziri nepeturu, nekuda kwekuita kwavo kwakasiyana kwemafuta, kushandiswa kwemhete dzepiston hakuna kufanana, mhete dzepiston dzekutanga dzinoumbwa nekukanda, asi nekufambira mberi kwehunyanzvi, simbi yakakwira-simba. zvindori zvepiston zvakazvarwa, uye nebasa reinjini, zvinodiwa zvezvakatipoteredza zvinoramba zvichivandudzika, zvakasiyana-siyana zvemhando yepamusoro yekurapa kwepamusoro, senge thermal spraying, electroplating, chrome plating, etc. Gasi nitriding, kuiswa kwemuviri, kupfeka kwepamusoro, zinc manganese. phosphating kurapwa, nezvimwewo, inovandudza zvakanyanya basa remhete yepiston.
Pini yepiston inoshandiswa kubatanidza piston kune tsvimbo yekubatanidza uye kupfuudza simba papiston kune tsvimbo yekubatanidza kana zvakasiyana.
Iyo piston yepiston inoiswa kune yakakura periodic kukanganisa mutoro pasi pekushisa kwakanyanya, uye nekuda kwekuti swing Angle yepiston yepini mugomba repini haina hombe, zvakaoma kuumba firimu rekuzora, saka mamiriro ekuzora haana kunaka. Nechikonzero ichi, piston yepiston inofanirwa kuve nekuoma kwakaringana, simba uye kupfeka kuramba. Huremu hudiki sezvingabvira, uye pini negomba repini zvinofanirwa kunge zvine maburi akakodzera ekufananidza uye kunaka kwepamusoro. Kazhinji, kuomarara kwepiston kunonyanya kukosha, kana piston pin bending deformation, inogona kukonzera kukuvadzwa kuchigaro chepiston.
Muchidimbu, mamiriro ekushanda kwepiston piston ndeyekuti chiyero chekumanikidza chakakura, firimu yemafuta haigone kuumbwa, uye deformation haina kurongeka. Nokudaro, kugadzirwa kwayo kunoda simba rakakwana remagetsi uye kupfeka kushorwa, asiwo simba rakanyanya kuneta.
Muviri wetsvimbo yekubatanidza inoumbwa nezvikamu zvitatu, uye chikamu chakabatana nepiston yepiston inonzi danda rekubatanidza musoro muduku; Chikamu chakabatana ne crankshaft chinodaidzwa kuti musoro muhombe wetsvimbo yekubatanidza, uye chikamu chinobatanidza musoro mudiki nemusoro muhombe chinodaidzwa kuti mutumbi wetsvimbo yekubatanidza.
Kuti uderedze kupfeka pakati pemusoro mudiki nepiston, iyo yakatetepa-yakavezwa bronze bushing inotsikirirwa mugomba remusoro. Dhora kana mill grooves mumisoro midiki nemakwenzi kuti ubvumire kupfachuka kwemafuta kuti apinde panzvimbo yekubatanidza yepini yekuzora bushing-piston.
Muviri wetsvimbo yekubatanidza itsvimbo yakareba, uye simba riri mubasa racho rakakurawo, kuitira kudzivirira kupfugama kwayo, muviri wetsvimbo unofanirwa kuva nekuoma kwakakwana. Nokuda kwechikonzero ichi, tsvimbo yekubatanidza yejini yemotokari inowanzotora chimiro I chikamu, chinogona kuderedza kuwanda pasi pemamiriro ezvinhu ekuti kuoma uye simba zvakakwana, uye injini yakasimba-yakasimba ine chikamu chakaita H. Mamwe mainjini anoshandisa tambo yekubatanidza diki musoro jekiseni mafuta ekutonhodza piston, iyo inofanirwa kudhiriwa kuburikidza negomba rerefu riri mumuviri wetsvimbo. Kuti udzivise kushushikana kwepfungwa, muviri wetsvimbo yekubatanidza, musoro muduku uye musoro mukuru zvakabatanidzwa nehombe denderedzwa yakatsetseka shanduko.
Kuti uderedze kuzunguzika kweinjini, mutsauko wehumburumbira wekubatanidza tsvimbo unofanirwa kuganhurwa kune hudiki, mumusangano wefekitori weinjini, kazhinji mumagiramu sechikamu chekuyera zvinoenderana nehukuru uye hudiki huremu hweinjini. tsvimbo yekubatanidza, injini imwechete yekusarudza boka rimwechete rekubatanidza tsvimbo.
Painjini yemhando yeV, masilinda anoenderana ari kuruboshwe uye kurudyi makoramu anogovera pini, uye tsvimbo yekubatanidza ine marudzi matatu: parallel yekubatanidza tsvimbo, forogo yekubatanidza tsvimbo uye huru uye yebetsero yekubatanidza tsvimbo.
Iwo mataira akaiswa pamabhureki akagadzika e crankshaft uye cylinder block uye anotamba basa rekubereka nekuzora anowanzo kunzi crankshaft bearing pads.
Crankshaft kutakura inowanzoparadzaniswa kuva marudzi maviri: kubereka (Mufananidzo 1) uye flanged kubereka (Mufananidzo 2). Flanged inotakura bushing haingogone kutsigira nekuzora crankshaft, asi zvakare kutamba chinzvimbo cheaxial chinzvimbo che crankshaft (panogona kungove nenzvimbo imwe chete pane crankshaft yekuseta axial positioning mudziyo).
Apo patinoshandisa mabhoti ekubatanidza tsvimbo, tichaona kuti kune matambudziko akawanda ekubatanidza mabhoti emudonzvo, pachava nezvinetso zvekuonekwa, matambudziko ekushivirira urefu, matambudziko ekuputsika, matambudziko eshinda yezino, matambudziko anowanikwa panguva yekuisa, nezvimwewo.
Nzira iri nyore ndeyekuedza bhaudhi yekubatanidza tsvimbo, tsvaga pane dambudziko uye uchinje. Iyo yekubatanidza tsvimbo yebhoti bvunzo inoda nzira. Kubatanidza tsvimbo yebhoti ibhoti yakakosha inobatanidza chigaro chekutakura chekuguma kukuru kwetambo yekubatanidza uye chivharo chekutakura. Iyo yekubatanidza tsvimbo yebhaudhi inoiswa pasi pekuita kwe preloading simba panguva yekuungana, uye yekubatanidza tsvimbo yebhaudhi inoiswawo kune chiito chekudzorera inertia simba apo injini yedhiziri ina-stroke iri kushanda. Iyo dhayamita yebhoti yekubatanidza tsvimbo idiki nekuti inoganhurwa nedhayamita yepini yepini uye yekunze vharanda saizi yemagumo makuru ekubatanidza tsvimbo.
Bhaudhi rinobatanidza chivharo chetsvimbo chinopatsanura kumucheto mukuru wetsvimbo yekubatanidza. Pamabhengi maviri ega ega, maviri kana mana mabhaudhi etsvimbo anowanzo shandiswa kuachengetedza. Mhando yebhaudhi inosiyana. Musoro unowanzo gadzirwa nendege yekumisikidza kana convex block yekumisikidza nekumisikidzwa neyakatakura tsigiro pamusoro kudzivirira bhaudhi yetsvimbo yekubatanidza kubva pakutenderera pakusunga nati. Iyo dhayamita yebhoti rodhi muviri pane imwe neimwe chikamu chepamusoro chekutakura yakakura, kuitira kuti inogona kuiswa negomba rebhoti panguva yekusangana; Iyo dhayamita yeimwe yakasara yebhoti tsvimbo yemuviri chikamu idiki pane dhayamita yegomba rebhaudhi, uye kureba kwakareba, kuitira kuti mutoro wechikamu cheshinda uderedzwe kana kukotama uye kukanganisa kutakurwa. Chikamu cheshinda chinowanzo tora shinda yakatsetseka nehupamhi hwepamusoro.
Kuti udzivise tambo yakarukwa kuti isasununguke, bhaudhi yetsvimbo yekubatanidza ine chisingaperi chinodzivirira-kusunungura chishandiso, chinowanzova cotter pini, anti-kusunungura washer uye copper plating pamusoro peshinda. Kubatanidza mabhaudhi etsvimbo anowanzo kutakura mitoro inochinjana, iyo iri nyore kukonzeresa kuneta kukanganisa uye kutyora, izvo zvinokonzeresa zvakakomba mhedzisiro. Naizvozvo, kazhinji inogadzirwa neyemhando yepamusoro alloy simbi kana yepamusoro-mhando kabhoni simbi, uye mushure mekupisa kupisa kurapwa. Mukutarisira, kutarisa kunofanira kubhadharwa pakuongorora kusimba kwayo kudzivirira kusunungura; Nguva dzose disassembly tarisa iyo yakatsemuka uye yakawandisa elongation, nezvimwewo, inofanira kutsiviwa nenguva kana zvichidikanwa. Paunenge uchiisa, zvakakosha kuyambuka uye zvishoma nezvishoma kusimbisa maererano neyakatemerwa pre-tightening simba, iyo isingagoni kuva yakakura kana kuti duku, kuitira kuti udzivise njodzi dzakadai sekuputika kwebhoti mubasa.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
