Pane zvinodikanwa pane yekumisikidza uye nzvimbo yekuisa?

Ehe.Kana paine mafirita esimbi, maburrs, guruva uye zvimwe zvinhu zvekune dzimwe nyika zvinopinda muberero, kutakura kunoburitsa ruzha uye kudedera panguva yekushanda, uye zvinogona kukuvadza mijaho uye zvinhu zvinotenderedza.Naizvozvo, usati waisa bearing, iwe unofanirwa kuve nechokwadi kuti inokwirisa pamusoro uye yekuisa nharaunda yakachena.

Mabearings anofanira kucheneswa here asati aiswa?

Kumusoro kwekutakura kunoputirwa nemafuta anorwisa-rust.Unofanira kurichenesa nemazvo nepeturu yakachena kana parafini, wozora rakachena, remhando yepamusoro kana giresi rekuzora rinopisa uye rinopisa zvikuru usati waisa nekushandisa.Hutsanana hune simba guru pakutakura hupenyu uye kuzunguzika uye ruzha.Asi isu tinoda kukuyeuchidzai kuti mabheya akavharirwa zvizere haadi kucheneswa nekuwedzerwa mafuta.

Ungasarudza sei mafuta?

Lubrication ine kukosha kwakanyanya pakushanda uye hupenyu hwemabheya.Pano tinokuzivisai muchidimbu mitemo yekusarudza girisi.Girisi inogadzirwa nebase mafuta, thickener uye additives.Zvimiro zvemhando dzakasiyana-siyana dzegirisi uye mhando dzakasiyana dzemhando imwechete yegirizi dzinosiyana zvakanyanya, uye inotenderwa kutenderera miganhu yakasiyana.Iva nechokwadi chekuteerera paunosarudza.Kuita kwegirisi kunonyanya kutsanangurwa nemafuta epasi.Kazhinji, yakaderera viscosity base oiri inokodzera yakaderera tembiricha uye yakanyanya kumhanya, uye yakakwira viscosity base mafuta inokodzera kupisa kwakanyanya uye mutoro wakakwira.Iyo thickener inobatanawo nekuita kwekuzora, uye kushorwa kwemvura kweiyo thickener kunosarudza kusamira kwemvura kwegirisi.Muchidimbu, magirosi emhando dzakasiyana haagone kusanganiswa, uye kunyange magirisi ane thickener akafanana achave nemhedzisiro yakaipa kune mumwe nemumwe nekuda kwezvimwe zvinowedzera.

Pakuzora mabearings, girizi yaunozora yakawanda ndiyo iri nani here?

Paunenge uchizora mabhero, ipfungwa isiriyo yakajairika yekuti kana uchiwedzera girizi, zviri nani.Mafuta akawandisa mumabhengi nemakamuri ekubereka anokonzeresa kusanganiswa kwegirisi, zvichikonzera kupisa kwakanyanya.Huwandu hwemafuta akazadzwa mukutakura hunofanira kukwana kuzadza 1/2 kusvika 1/3 yenzvimbo yemukati yekubereka, uye inofanira kuderedzwa kusvika 1/3 nekumhanya kukuru.

Nzira yekuisa uye disassemble?

Panguva yekuisa, usagadzirisa zvakananga chiso chekupedzisira uye chisina kusimbiswa pamusoro pekubereka.Dzvanya mabhuraki, maoko kana mamwe maturusi ekuisa (tooling) anofanirwa kushandiswa kuenzana kusimbisa kubereka.Usaise kuburikidza ne rolling elements.Kana iyo yekumisikidza yakashongedzwa, iyo yekumisikidza ichaenda zvakanyanya.Kana kupindira kwakakodzera kwakakura, kutakura kunofanira kuiswa mumafuta emaminerari uye kupisa kusvika 80 ~ 90°C isati yaiswa nekukurumidza.Nyatsodzora tembiricha yemafuta kuti isapfuure 100°C kudzivirira kushatirisa mhedzisiro kubva mukuderedza kuomarara uye kukanganisa dimensional kupora.Paunosangana nematambudziko muku disassembly, zvinokurudzirwa kuti ushandise disassembly chishandiso kudhonzera kunze uchinyatsodira mafuta anopisa parin'i yemukati.Kupisa kuchawedzera mhete yemukati yekubereka, zvichiita kuti zvive nyore kudonha.

Iyo idiki iyo radial clearance yekubereka, zviri nani?

Haasi ese mabhengi anoda kushoma kushanda clearance, iwe unofanirwa kusarudza iyo yakakodzera clearance zvinoenderana nemamiriro ezvinhu.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. Iyo yemvumo yemvumo inorongeka kubva kudiki kusvika kuhombe, pakati peboka ripi. 0 ndiyo yakajairika clearance.Iyo yakakosha radial clearance boka inokodzera zvakajairwa kushanda mamiriro, yakajairika tembiricha uye inowanzo shandiswa kukanganisa inokwana;mabheya anoshanda pasi pemamiriro akakosha akadai sekushisa kwakanyanya, kumhanya kwakanyanya, ruzha rwakaderera uye kukwesha kwakaderera kunofanirwa kushandisa yakakura radial clearance;kune mabearings anoshanda pasi pemamiriro akakosha akadai sekushisa kwakanyanya, kumhanya kwakanyanya, ruzha rwakaderera, kukweshana kwakaderera, nezvimwewo. Mabearings ezvekukwenenzverwa maspindles uye maspindle emuchina wekushandisa anofanirwa kushandisa madiki radial clearances;roller bearings inogona kuchengetedza shoma shoma yekushanda clearance.Mukuwedzera, hapana mvumo yekutakura kwakasiyana;pakupedzisira, kushandiswa kwekushanda kwekutakura mushure mekuiswa kuduku kudarika kusunungurwa kwepakutanga kusati kwaiswa, nokuti kutakura kunofanira kutsungirira kumwe kutenderera kwemutoro, uye kunewo kupesana kunokonzerwa nekutakura uye mutoro.Kuwanda kwe elastic deformation.
