1. Crankshaft inobereka kunyunguduka kukundikana

Kana crankshaft inotakura inyunguduka, mashandiro einjini mushure mekunge kukanganisa kwaitika ndekwekuti: ruzha uye rune simba rekugogodza simbi inoburitswa kubva kune yakanyungudika main bear. Kana mabhengi ese akanyunguduka kana kusununguka, pachava nekujeka "dang, pang" ruzha. Chikonzero chekukundikana

(1) Kutsikirira kwemafuta ekuzora hakuna kukwana, mafuta ekuzora haakwanise kusvina pakati pe shaft nebearing, zvekuti shaft nebearing zviri mu semi-dry or dry friction state, izvo zvinoita kuti tembiricha yeberero ikwire. uye anti-friction alloy inonyungudika.

(2) Mufambiro wemafuta ekuzora, muunganidzi wemafuta, chisefa chemafuta, nezvimwe zvakavharwa netsvina, uye vharafu yekupfuura pa strainer haigone kuvhurwa (iyo preload yechitubu chevharuvhu yakakura kwazvo kana chitubu nebhora vharafu zvakanamira ne. tsvina, nezvimwewo), Yakakonzera kukanganisa kwemafuta ekuzora.

(3) Mukaha uri pakati peshaft nebearing idiki kwazvo kuti igadzire firimu remafuta; kutakura kupfupika uye hakuna kuvhiringidza negomba reimba inotakura, zvichiita kuti kutakura kutenderere mugomba reimba, kuvhara gomba rekufamba kwemafuta pagomba reimba inotakura, uye kukanganisa kugoverwa kwemafuta ekuzora.

(4) Kutenderera kwejenari re crankshaft kwakashata. Munguva yekuzora mafuta, zvakaoma kuumba imwe firimu remafuta nekuti jenari haina kutenderera (inotakura kubvumidzwa dzimwe nguva yakakura uye dzimwe nguva idiki, uye firimu remafuta dzimwe nguva gobvu uye dzimwe nguva rakatetepa), zvichikonzera kusanaka kwemafuta.

(5) Kuchinja kwemuviri kana kutakura kukanganisa kugadzirisa, kana kupeta kwe crankshaft, nezvimwewo, ita kuti mitsetse yepakati yeberero guru rega rega isaenderane, zvichiita kuti mafuta emufirimu weberero rega rega asaenzana kana crankshaft ichitenderera, uye kunyange kuoma kukwenya. mamiriro kunyungudutsa fani.

(6) Huwandu hwemafuta ekuzora mupani yemafuta hauna kukwana uye tembiricha yemafuta yakanyanya, kana mafuta ekuzora anonatswa nemvura kana peturu, kana mafuta ekuzora emhando yakaderera kana mhando isingaenderane anoshandiswa.

(7) Kusakwana kwakashata pakati pemashure ekubereka uye gomba rechigaro chekutakura kana mhangura padding, nezvimwewo, zvichiita kuti kupisa kusina kunaka.

(8) Kuwedzera kwekukurumidza kweinjini, se "kumhanya" kweinjini yedhiziri, zvakare chimwe chezvikonzero zvekupisa kwemabheya.

Kudzivirira kukanganisa uye nzira dzekugadzirisa matambudziko

(1) Usati waisa gungano rejini, teerera kucheneswa uye kuongororwa kwenzvimbo yemafuta ekuzora (geza nemvura inodzvanyirira kana mweya), bvisa marara anovharira muunganidzi wesefa, uye simbisa kuchengetedzwa kweiyo coarse sefa kudzivirira. iyo sefa chinhu kubva pakuvharika uye vharafu yekunzvenga Isingashande.

(2) Mutyairi anofanira kucherechedza tembiricha yeinjini uye kudzvanywa kwemafuta ekuzora chero nguva, uye kutarisa kuti hapana ruzha rwusina kujairika muinjini; tarisa huwandu uye kunaka kwemafuta ekuzora usati wasiya mota.

(3) Kuvandudza kunaka kwekugadzirisa injini uye kusimbisa kusati kwagadzirisa kuongorora kwezvikamu zvakakosha.

(4) Kukweshwa kwebhingi guru re crankshaft kunofanira kuita kuti pakati pegomba rimwe nerimwe rinotakura buri rive nechepakati. Panyaya yekutsauka kudiki uye kugadzirisa nechido, nzira yekukwenya yekutanga kugadzirisa mutsara wakatwasuka unogona kushandiswa. Basa rekukwenya rinoenderana nekutakura tsvimbo yekubatanidza. Zvakangofanana.

2. The crankshaft main bearing inoita ruzha

Kuita kweinjini mushure meruzha kubva ku crankshaft bearing kunokonzerwa nekukanganisa kwe crankshaft main journal uye kutakura. Kana iyo huru inotakura inonyunguduka kana kudonha, injini inodedera zvakanyanya kana chinokwidziridza chinyadzo chakaora moyo zvakanyanya. Iyo huru inotakura yakapfekwa, uye iyo radial clearance yakakura kwazvo, uye pachava neinorema uye isinganzwisisi kugogodza ruzha. Iyo yakakwirira yeinjini kumhanya, iyo inonzwika ruzha, uye ruzha runowedzera nekuwedzera kwemutoro. Chikonzero chekukundikana

(1) Bearings nemagazini zvinopfekwa zvakanyanyisa; mabhaudhi ekusimbisa echifukidzo chekutakura haana kuvharwa zvakasimba uye akasunungurwa, izvo zvinoita kuti kuenzana kwemvumo pakati pe crankshaft uye kutakura kwakakura zvikuru, uye iyo miviri inoita ruzha painodhumhana.

(2) Iyo inotakura alloy inonyunguduka kana kudonha; kutakura kwakarebesa uye kupindira kwakakura kwazvo, zvichiita kuti fanidzo iparare, kana kubereka kupfupi kwazvo kuti risagone kumira zvakanaka uye rakasununguka mugomba reimba inotakura, zvichiita kuti maviri acho akonderane.

Kudzivirira kukanganisa uye nzira dzekugadzirisa matambudziko

(1) Kuvandudza kunaka kwekuchengetedza injini. Mabhoti ekugadzirisa evhavha yekutakura inofanira kusimbiswa uye yakavharwa. Kutakura hakufanire kunge kwakareba kana kupfupika kuti ive nechokwadi chekuvhiringidza kwakati.

(2) Giredhi remafuta ekuzora rinoshandiswa rinofanira kunge rakarurama, hapana mafuta akaderera anofanira kushandiswa, uye tembiricha yakakodzera yemafuta uye kumanikidza kunofanira kuchengetedzwa.

(3) Chengetedza chimiro chakanaka chekushanda chegadziriro yekuzora, tsiva mafuta ekuzora nenguva, uye chengetedza sefa yemafuta ekuzora nguva nenguva.

(4) Paunenge uchityaira, mutyairi anofanira kungwarira kuchinja kweoiri, uye nokukurumidza kutarisa kana mhinduro isina kujairika yawanikwa. Kana gomba rekutakura richikwira, iro gomba rekutakura rinofanira kugadziriswa. Kana isingakwanisi kugadziriswa, kutakura kunogona kuchinjwa uye kukweshwa. Kana cylindricity yejenari ye crankshaft ikadarika muganho wesevhisi, crankshaft jenari inofanirwa kukwenenzverwa uye kutakura kunofanirwa kusarudzwa zvakare.
