Crankshaft inobereka gwenzi.
Iwo mataira akaiswa pamabhureki akagadzika e crankshaft uye cylinder block uye anotamba basa rekubereka nekuzora anowanzo kunzi crankshaft bearing pads.
Crankshaft bearing rinowanzo kupatsanurwa kuva marudzi maviri: kubereka uye kubereka flanging. Flanged inotakura goko haingogone chete kutsigira nekuzora iyo crankshaft, asi zvakare kutamba chinzvimbo cheaxial chinzvimbo che crankshaft.
notch
Zvinyorwa zvematairi maviri zvinofanira kutarisana nedivi rimwe chete, uye kana tsvimbo yekubatanidza inotakura gwenzi yakakosha kumativi ose maviri, zviratidzo padivi rekubatanidza tsvimbo inofanira kuonekwa.
Kutakura kureba
Iyo itsva inotakurwa inotakurwa mugomba rechigaro, uye imwe neimwe magumo ekumusoro uye ezasi zvidimbu zviviri zvinofanirwa kuve 0.03-0.05mm yakakwirira kupfuura iyo inotakura chigaro ndege. Kuve nechokwadi chekuti ganda rinotakura uye gomba rechigaro zvakanyatsoenderana, gadzirisa kupisa kwekupisa.
Iyo nzira yeempirical yekutarisa kureba kwegwenzi rinotakura ndeiyi: gadza gwenzi rinotakura, isa chivharo chegwenzi chinotakura, simbisa imwe yekupedzisira bhauti zvinoenderana neyakatsanangurwa torque kukosha, isa gasket ye0.05mm ukobvu pakati peimwe chivharo chekupedzisira uye chinotakura. gwenzi chigaro ndege, apo torque ye sikuruu kuguma bhaudhi inosvika 10-20N · m, kana gasket isingagoni kubudiswa, inoratidza kuti kutakura kureba kwakareba, uye kuguma kusina kumira pamwe chete kunofanira kuva faira pasi; Kana iyo gasket inogona kubudiswa, inoratidza kuti urefu hwekutakura hwakakodzera; Kana iyo gasket isingasviki kune yakatsanangurwa torque kukosha, haigone kubviswa, zvichiratidza kuti gwenzi rinotakura rakapfupika uye rinofanira kusarudzwa zvakare.
Smooth back tenon yakanaka
Kudzokera kumashure kunofanirwa kunge kusina mavara, kushata kwepamusoro Ra iri 0.8μm, tenon inogona kudzivirira kutakura bushing kutenderera, basa rekuisa, senge tenon yakadzikira, rinogona kushandiswa kukanganisa hurefu hwakakodzera, senge kukuvara kwetenon, inofanira kudzokororwa- yakasarudzwa inobereka bushing.
Elastic fit pasina husk
Mushure mekuisa gwenzi idzva rekubereka pachigaro chekutakura, curvature radius yebhishi rinotakura rinodiwa kuti rive rakakura kudarika curvature radius yegomba rechigaro. Kana gwenzi rinotakura rinotakurwa mugomba rechigaro, rinogona kunyatsobatanidzwa negomba rechigaro chekutakura nechitubu chegwenzi rinotakura pacharo kuti ribatsire kupisa kupisa. Tarisa uone kana goko rinotakura riri mbeveve, unogona kubata kumashure kwegoko rinotakura kuti utarise, pane mbeveve inonzwika inoratidza kuti alloy uye pasi ndiro haina kusimba, inofanira kusarudzwa zvakare.
Iyo inofananidzwa gap ye shaft tile jenari inofanirwa kuve yakakodzera
Kana iyo goko rekubereka rasarudzwa, gaka rinoenderana rinofanira kuongororwa. Panguva yekuongorora, cylinder gauge uye micrometer inoyera gwenzi rinotakura uye jenari, uye mutsauko ndiko kubvumidzwa kwakakodzera. Nzira yekuongorora yekucheneswa kwegwenzi rinotakura ndeiyi: kune tsvimbo yekubatanidza, shandisa chidimbu chemafuta pagwenzi rinotakura, simbisa tsvimbo yekubatanidza pajenari rinoenderana, simbisa bhaudhi zvinoenderana neiyo torque yakakosha, uye ipapo swing. tsvimbo yekubatanidza neruoko, inogona kutenderera 1 ~ 1/2 kutendeuka, kudhonza tsvimbo yekubatanidza pamwe chete neaxis direction, hapana gap kunzwa, kureva, kusangana nezvinodiwa; Kune crankshaft shingles, isa mafuta pamusoro pehuro yega yega uye inobereka shingles, isa crankshaft uye simbisa mabhaudhi zvinoenderana neyakatsanangurwa torque kukosha, uye dhonza crankshaft nemaoko maviri, kuti crankshaft itendeuke 1/2 kutendeuka, uye kutenderera kwakareruka uye yunifomu pasina kuvhara chiitiko.
Yakakodzera yekuisa nzira ye crankshaft tile
Kuiswa kwakakodzera kwematairi e crankshaft kunosanganisira anotevera matanho akakosha:
Kuisirwa bharanzi shaft: Isa chiyero shaft padivi rega rega re crankshaft. Aya mabhanhire mashefu anovimba nekupfapfaidza mafuta ekuzora, pane kumanikidzira kudzosa kuburikidza nepombi yemafuta. Naizvozvo, iyo gap control pakati peyerenji shaft uye inotakura goko inonyanya kukosha uye inofanirwa kuchengetwa pakati pe0.15- 0.20 mm.
Gap control uye kugadzirisa: Kana iyo gap isiri nyore kudzora, unogona kutanga washandisa feeler kuyera mukaha pakati pegwenzi rinotakura uye chiyero shaft kana gwenzi rinotakura risati raiswa kune cylinder block. Iyo gap inokurudzirwa ndeye 0.3 mm. Kana iyo gap iri pasi pe 0.3 mm, saizi inodiwa inogona kuwanikwa nekukwenya kana machining pane lathe kuti ive nechokwadi chekuti chiyero chekupindira pakati pegwenzi rinotakura uye gomba rekubereka ndeye 0.05 mm, uye gaka rinenge 0.18 mm mushure mekubereka. gwenzi rinopinzwa mugomba rekubereka.
Yakagadzika gwenzi rinotakura: Pakuisa chiyero shaft inotakura gwenzi, 302AB glue inofanirwa kuiswa kuseri kwegwenzi rinotakura kuti iwedzere kugadzikana kwegwenzi rinotakura uye kudzivirira kuti isafambe kana kusunungura.
Kutakura chinzvimbo uye lubrication: yega yega goko rinotakura rine bump yekumisikidza, iyo inofanirwa kunamira mune yekumisikidza slot pane cylinder block. Panguva imwecheteyo, ita shuwa kuti gomba remafuta mubereko rinoenderana nechikamu chemafuta mucylinder block kuitira kumisikidza iyo lubrication system.
Kutakura kuisirwa chivharo chekuisa: Mushure mekuisa yekutanga kubereka chivharo, shandura crankshaft kuti uone kuti hapana chakamira. Isa chivharo chekubereka uye uisimbise maererano nezvinodiwa. Izvi zvinoitwa kune imwe neimwe inotakura cap. Kana chivharo chekutakura chakanamatira, dambudziko rinogona kunge riri muvharo yekutakura kana muchikamu chekutakura. Bvisa uye tarisa maburrs kana kusakwana kwechigaro chekutakura.
Nekutevera nhanho idzi, unogona kuve nechokwadi chekumisikidzwa kwakaringana kwematairi e crankshaft uye kudzivirira kutadza kwemuchina nekuda kwekuisa zvisina kunaka.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
