Chisimbiso chemafuta chisimbiso chakagadzirirwa kuvhara majoini ezvikamu zvinotenderera zvemotokari.Pasinei nekuita sekureruka uye ruzivo rwakakura rwekushandiswa mumotokari, dhizaini uye kusarudzwa kwechikamu ichi ibasa rakakosha uye rakaoma.
Zvisizvo 1: Kusarudza chisimbiso cheoiri, zvakakwana kuti uzive hukuru hwayo
Saizi yakakosha, asi kure neiyo chete parameter.Nehukuru hwakafanana, zvisimbiso zvemafuta zvinogona kusiyanisa zvakanyanya muzvinhu zvavo uye chiyero.Nokuda kwechisarudzo chakarurama, iwe unoda kuziva hurumende yekushisa umo chisimbiso chemafuta chichashanda, kutungamira kwekutenderera kwe shaft yekuisa, kana maitiro ekugadzira akadai semazamu maviri anodiwa.
Mhedziso: nokuda kwekusarudzwa kwakarurama kwechisimbiso chemafuta, unoda kuziva zvose zvayo, uye ndezvipi zvinodiwa zvinogadziriswa nemugadziri wemotokari.
Zvisizvo 2. Zvisimbiso zvemafuta zvakafanana uye kusiyana kwemutengo kunobva pamakaro emugadziri.
Muchokwadi, zvisimbiso zvemafuta zvinogona kugadzirwa nezvinhu zvakasiyana kana nenzira dzakasiyana.
Zvishandiso zvinoshandiswa kugadzirwa kwemafuta seal:
● ACM (acrylate rubber) - kupisa kwekushanda -30 ° C ... + 150 ° C. Zvinhu zvakachipa, zvinowanzoshandiswa pakugadzira zvisimbiso zvehubhu.
● NBR (mafuta-uye-petroli-resistant rubber) - kutonhora kwekushanda -40 ° C ... + 120 ° C. Inoratidzwa nekupikisa kukuru kune marudzi ose emafuta uye mafuta.
● FKM (fluororubber, fluoroplastic) - kupisa kwekushanda -20 ° C ... + 180 ° C. Chinhu chinonyanya kushandiswa pakugadzirwa kwemafuta ecamshaft zvisimbiso, crankshafts, nezvimwewo. pamwe chete nezvinogadzirisa, oiri, zvitubu uye zvinonyungudutsa.
● FKM+ (yakanzi fluororubbers ine zvimwe zvinowedzera) - kupisa kwekushanda -50 ° C ... + 220 ° C. Patented zvinhu zvinogadzirwa nehuwandu hwemakemikari makuru ekubata (Kalrez naViton (yakagadzirwa neDuPont), Hifluor (yakagadzirwa naParker) , pamwe chete nezvinhu Dai-El uye Aflas).Izvo zvakasiyana kubva kune yakajairwa fluoroplastic neyakakura tembiricha siyana uye yakawedzera kuramba kune acids nemafuta uye mafuta ekuzora.
Zvakakoshawo kuziva kuti panguva yekushanda, chisimbiso chemafuta hachibati pamusoro pechifukidzo, chisimbiso chinoitika nekuda kwekugadzirwa kwevhavha munzvimbo yekutenderera kweshaft uchishandisa zvinyorwa zvakakosha.Nhungamiro yavo inofanirwa kuverengerwa pakusarudza, kana zvisina kudaro notches haizosveta mafuta mumuviri, asi zvinopesana - isundire kunze uko.
Kune marudzi matatu emanotsi:
● Kutenderera chaiko
● Kutenderera kuruboshwe
● Inodzokororwa
Pamusoro pezvinhu, zvisimbiso zvemafuta zvakare zvakasiyana mukugadzira tekinoroji.Nhasi, nzira mbiri dzekugadzira dzinoshandiswa: kugadzira nematrix, kucheka kubva pakuvhara nekucheka.Muchiitiko chekutanga, kutsauka kwezviyero uye zvimiro zvechisimbiso chemafuta hazvibvumirwi pamwero wetekinoroji.Mune yechipiri, ine huwandu hukuru hwekugadzira, kutsauka kubva kushiviriro kunogoneka, semhedzisiro iyo chisimbiso chemafuta chave chine zviyero zvakasiyana kubva kune zvakatarwa.Chisimbiso chakadaro chemafuta chinogona kusapa chisimbiso chakavimbika uye chinotanga kudonha kubva pakutanga, kana kukurumidza kutadza nekuda kwekukweshana pashaft, panguva imwe chete ichikuvadza pamusoro peiyo shaft pachayo.
Kubata chisimbiso chitsva chemafuta mumaoko ako, edza kukotamisa mucheto waro wekushanda: mune chisimbiso chitsva chemafuta, chinofanira kunge chiri elastic, kunyange uye chakapinza.Iyo yakanyanya kupinza, zviri nani uye zvakareba iyo itsva chisimbiso chemafuta chichashanda.
Pazasi pane pfupi pfupi tafura yekufananidza yemafuta zvisimbiso, zvinoenderana nerudzi rwezvinhu uye nzira yekugadzira:
