Paunenge uchiisa, usaite nyundo yakananga iyo inobereka magumo kumeso uye isina-kusimbiswa pamusoro.Press block, sleeve kana mamwe maturusi ekuisa anofanirwa kushandiswa kugadzira iyo inotakura bere yunifomu simba.Usaisa nekukungurutsa muviri.Kana iyo yekumisikidza yakashongedzwa, ichaita kuti kuisirwa kuve kwakanyanya.Kana kupindira kwakakodzera kwakakura, kutakura kunofanirwa kupiswa kusvika 80 ~ 90 ℃ mumafuta emaminerari uye kuiswa nekukurumidza sezvinobvira, kunyatso kudzora tembiricha yemafuta haipfuure 100 ℃, kuitira kudzivirira kudzikisira mhedzisiro yekuomarara uye kukanganisa saizi kupora.Paunosangana nematambudziko mukuparadzana, zvinokurudzirwa kuti ushandise disassembly chishandiso kudhonzera kunze uchinyatso kudira mafuta anopisa pachindori chemukati, kupisa kuchaita kuti mhete yemukati iwedzere, kuitira kuti zvive nyore kudonha.
Haasi ese mabhengi anoda hushoma kushanda clearance, iwe unofanirwa kusarudza iyo yakakodzera clearance zvinoenderana nemamiriro.Muchiyero chenyika 4604-93, iyo radial clearance ye rolling bearings yakakamurwa kuita mapoka mashanu: boka 2, boka 0, boka 3, boka 4 uye boka 5. Hunhu hwemvumo hunotevedzana kubva kudiki kuenda kuhombe, uye boka 0 ndiyo chiyero. clearance.Basic radial clearance group inokodzera zvakajairwa mashandiro emamiriro, tembiricha yakajairwa uye kupindirana kwakajairika;Yakakura radial clearance inofanirwa kusarudzirwa mabheya anoshanda pasi pemamiriro akakosha akadai senge tembiricha yakakwira, kumhanya kwakanyanya, ruzha rwakaderera uye kuderera.Diki radial clearance inofanirwa kusarudzwa kuti inyatso spindle uye muchina chishandiso chekuruka mabheji;Diki yekushanda clearance inogona kuchengetedzwa kune roller bearings.Mukuwedzera, hapana mvumo yekutakura kwakaparadzaniswa;Pakupedzisira, kubvumirwa kwekushanda kwekutakura mushure mekuiswa kunofanira kuva kuduku kudarika kubvumirwa kwepakutanga kusati kwaiswa, nokuti kutakura kunofanira kutakura kumwe kutenderera kwemutoro, pamwe chete nekuputika kwe elastic kunokonzerwa nekutakura zvakakodzera uye mutoro.
Tichitarisa dambudziko rekuvhara chisimbiso chemabheya ane chisimbiso chakaiswa, pane matanho maviri anofanirwa kuitwa zvakanyatsonaka mukugadzirisa.
1. Inlaid chisimbiso chisimbiso chifukidziro chechifukidziro chinoshandurwa kumativi ose maviri ekutakura, uye chimiro chekuisa chekutakura chinogadziriswa kubva kune midziyo.Kubatana kwakananga nekutakura hakudiwi, uye kutakura iguruva-uchapupu kubva kunze kwekubereka.Iyo yekuisa chisimbiso chechimiro ichi chakakwira kupfuura iyo yekutakura pachayo inotengeswa neanotakura mumiriri, iyo inovhara zvakananga nzira yekupinda yegranular zvinhu uye inovimbisa kuchena kwemukati unotakura.Ichi chimiro chinovandudza kupisa kwekupisa nzvimbo yekutakura uye hachikonzeri kukanganisa kunopesana nekuneta kwekuita kwekutakura.
2. Kunyange zvazvo nzira yekunze yekuisa chisimbiso yekutakura ine chisimbiso chakanaka chekuvhara, nzira yekupisa inopisa yakavharwawo, saka zvikamu zvekutonhora zvinoda kuiswa.Chishandiso chekutonhodza chinogona kudzikisa tembiricha yekushanda kwelubricant, uye tembiricha yakanyanya kushanda yemabheri inogona kudzivirirwa kuburikidza nekupisa kwechisikigo kupera mushure mekutonhora.
